技术领域 FIELD

[0002] 本发明是关于计算机正畸术及牙医术。 [0002] The present invention relates to computer orthodontic surgery and dental surgery. 背景技术 BACKGROUND

[0003] 在正畸术治疗中,使用各种器具来将患者牙齿自初始位置移动至最终位置。 [0003] In the orthodontic treatment, the use of a variety of instruments to the patient teeth from an initial position to a final position. 器具对牙齿施加力,藉此移动一颗或多颗牙齿或将其保持在治疗阶段的适合位置。 Dental appliance for applying a force, thereby moving one or more teeth, or to maintain it at the appropriate stage of the treatment position.

[0004] 正畸术移动因牙齿位置与器具之间的一对一关系而造成,其机理是:将牙齿「挤」 成新外形并保持就位,由此允许牙齿有足够的时间适应新位置,之后,再次重复此过程,在治疗计划的不同治疗阶段牙齿会逐渐地移动。 [0004] Orthodontic surgery by moving one relationship between the position of the teeth caused by the appliance, the mechanism is: the teeth "squeezed" into a new shape and held in place, thereby allowing sufficient time for the teeth adapt to the new position After that, repeat this process at different stages of treatment dental treatment plan will gradually be moved.

[0005] 在当前治疗状态与后续目标或n+1治疗阶段之间的一对一关系中,牙科器具的适应可包括塑胶与牙齿几何形状之间的交互作用,该交互作用对于实现n+1牙齿位置并非最佳且通常不将该交互作用纳入该一对一关系的考量中。 [0005] In the current state of the follow-up treatment goals or n + 1-one relationship between the treatment phase, the adaptation may include a dental appliance geometry of the interaction between the plastic and the teeth, which interact to achieve n + 1 tooth position is not the best, and usually not into account the interaction of the one relationship. 对于较大的牙齿移动距离而言,尤其如此,在较大牙齿移动距离的情形下,器具的变形量可导致器具中的拉伸和应力,因此, 矫正器的一些区域与牙齿的关键区域和/或合意的区域并非密切地接触。 For larger distances in terms of tooth movement, particularly, in the case of the larger tooth movement distance, the amount of deformation can cause the appliance to the appliance and the tensile stress, therefore, of critical areas, and some areas of the aligner and the tooth Regional / or intimate contact is not desirable. 因此,无法将牙齿移动至合意的目标位置。 Therefore, you can not move teeth to a desired destination. 此外,还存在相反的效果,牙齿可能接触对于到达合意或目标位置产生反作用的区域。 In addition, there is also the opposite effect, the teeth may be exposed to reach a desired or target position counterproductive area.

[0006] 另外,牙科附件主要用于改变牙冠的几何形状,以确保更好地固持牙具,如沿合意移动的方向的矫正器。 [0006] Further, dental attachments used mainly to change the geometry of the crown, in order to ensure a better holding teeth, such as moving along the aligner desirable direction. 一般而言,该等附件用以在牙齿的垂直表面上提供「凸起」或「倒凹」,否则牙具难以固持牙齿。 Generally speaking, these accessories for the vertical surfaces of the teeth with the "bump" or "undercut", otherwise retaining teeth with hard teeth.

[0007] 实现牙齿的合意移动的现有方法包括:在治疗阶段的当前位置或η位置期间,根据计划的下一个位置或n+1位置来制造牙具并将其置于牙齿上。 Desirable to move the conventional method [0007] to achieve a tooth comprising: during the treatment phase of the current position or η position, according to the next position or location program n + 1 is manufactured and placed on the teeth with the teeth. 通常而言,我们假设,牙具或其若干部分的变形所产生的力和转矩(其是因用于牙具制作的牙齿位置与牙具所定位的牙齿的位置之间的差别而造成的)会致使牙齿移动到治疗阶段中的下一个计划位置中。 Generally speaking, we assume that a tooth or several parts of the deformation produced by the force and torque (which is due to differences in the position of making teeth with teeth with tooth position and the position of the teeth caused by used between) will cause Teeth move to the next phase of treatment plan location.

[0008] 然而,在实践中,无论在治疗中是否使用牙科附件,所产生的力和转矩的取向皆可能并非沿着既定牙齿移动的方向。 [0008] However, in practice, no matter whether in the treatment of dental attachments, force and torque generated by the orientation direction are not likely to move along a predetermined tooth. 此外,可仅针对牙冠而不考量牙根或其他解剖学结构来程序化或配置当前的牙齿移动。 In addition, only without consideration for the root crown or other anatomical structure or configuration of the current program of tooth movement. 牙根或其他解剖学结构可阻碍牙冠移动,并使得阻力中心向下处于牙骨槽内。 Root or other anatomical structures can hinder the crown is moved downwardly and such that the center of resistance of the bone in the tooth slot. 一般而言,因作用于牙冠的力而形成的对阻力中心的非有利转矩可能无法轻易地平衡。 In general, the center of resistance of the non-beneficial torque force acting on the crown may not be formed easily balanced. 此外,随着治疗过程期间的牙齿移动,牙具的变形逐渐减小,使得所施加的力亦随的减弱。 In addition, with the deformation tooth movement during the course of treatment, dental equipment decreases, so that weakened in tandem with the applied force.

[0050] 现在,三维正畸治疗计划工具(除其他以外,如AlignTechnology,Inc.的软件或可自eModels和OrthoCAD处购得的其他软件)使得数位治疗计划成为可能。 [0050] Now, the three-dimensional orthodontic treatment planning tools (among other things, such as AlignTechnology, Inc. Software or other software that can be customized at eModels and OrthoCAD purchased) makes several treatment plan possible. 此等技术允许临床医师使用实际的患者齿系作为自订治疗计划的起始点。 Such technology allows clinicians to use actual patient dentition as a starting point for a custom treatment plan. 相比于2003年8月21日提出的美国专利申请案序号10/640,439及2002年8月22日提出的美国专利申请案序号10/225,889中所论述的原始数位治疗计划,自Align Technology公司购得的软件技术是使用针对患者的数位模型来制定治疗计划,然后扫描所实现的治疗结果或实际的治疗结果来评估结果的「治疗成功程度」。 Compared to August 21, 2003 made US Patent Application Serial No. 10 / 640,439 original digital treatment planning and August 22, 2002 proposed by the United States Patent Application Serial No. 10 / 225,889 as discussed above, since Align Technology Corporation under software technology is used for the digital model of the patient to develop a treatment plan, and then scans the results of treatment achieved or actual treatment results to evaluate the results of the "degree of success of the treatment." 数位治疗计划和结果评估所存在的问题是数据冗余,并且缺乏以个体患者水平评估治疗成功度的标准和有效的方法。 Digital treatment planning and outcome evaluation problem is data redundancy, and the lack of individual patient in order to assess the level of success of the treatment standards and effective method. 使用牙科数据挖掘系统来分析信息。 Use dental data mining system to analyze information.

[0051] 图IA显示一个例示性牙科数据挖掘系统。 [0051] Figure IA displays an exemplary dental data mining systems. 在该系统中,牙科治疗数据集及结果数据集1存储在数据库或信息库2中。 In this system, dental treatment and outcome data set a data set stored in a database or repository 2. 数据挖掘软件3提取数据,由此产生结果4。 3 data mining software to extract data, the resulting outcome 4. 数据挖掘软件可询问在数据库2中捕获和/或更新的信息,并且可产生与患者牙病以及牙具解决方案相关的输出数据流。 Data mining software can ask the capture and / or update the information in the database, 2, and can produce dental patients and dental equipment and solutions related to the output data stream. 请注意,最为有利地是,可将数据挖掘软件的输出作为后续输入以自反射方式馈送至至少数据库及数据挖掘相关性算法。 Please note that most advantageously can export the data mining software as a self-reflective manner subsequent input is fed to at least the database and data mining algorithms.

[0052] 图IA的数据挖掘系统的结果是用于定义器具构形或定义器具构形的改变,以逐步地移动牙齿。 [0052] The results in Fig. IA data mining system is used to define the configuration of the appliance or equipment configuration changes to the definition in order to gradually move the teeth. 牙齿移动通常是与正畸治疗相关联的移动,包括全部三个正交方向的平移、 牙齿中心线沿两个正交方向的转动(其中转动轴垂直于垂直中心线)(「根成角」和「转矩」)、以及牙齿中心线沿正畸方向的转动(其中轴线平行于垂直中心线)(「纯转动」)。 Tooth movement is usually associated with movement orthodontic treatment, including translation in all three orthogonal directions, two orthogonal directions along the center line of the teeth of the rotation (which is perpendicular to the vertical centerline axis of rotation) ("root angulation" and "torque"), as well as dental orthodontic direction along the rotation center line (the axis of which is parallel to the vertical centerline) ("pure rotation").

[0053] 在一个实施例中,数据挖掘系统捕获3-D治疗计划的移动、起始位置及最终实现的牙位置。 [0053] In one embodiment, a data mining system to capture movement, starting position and ultimately tooth position of 3-D treatment planning. 该系统将结果与计划相比较,且可使用任何治疗方法来实现该结果,该等治疗方法包括:可移除式器具及固定式器具(如正畸托架和钢丝)、或甚至其他牙科治疗(如将实现结果与计划相比较以便进行正畸手术、牙周病治疗及恢复性治疗)。 The system compares the results with the plans, and may be used in any therapeutic method to achieve this result, such a method of treatment comprising: a removable appliances and fixed appliances (such as orthodontic brackets and wires), or even other dental treatment (as will achieve the results compared with the plan for orthodontic surgery, periodontal treatment and restorative treatment).

[0054] 在一实施例中,牙齿重迭工具是用以匹配每一牙齿牙弓扫描的治疗档案。 [0054] In one embodiment, the dental tool is used to match the treatment overlap each tooth arch file scan. 精化扫描(后续进展)重叠在初始扫描上,以基于牙齿解剖结构和齿座标系统达成匹配。 Refinement scan (subsequent progress) is superimposed on the initial scan, based on the anatomy of the tooth and the tooth coordinate system to reach match. 在两个牙弓中的牙齿匹配之后,重叠工具需要参照以便将上牙弓与下牙弓联系起来。 After the dental arch in the two match, overlapping tools need to refer to the upper dental arch and the lower dental arch link. 当选择选项「统计过滤」时,重迭工具藉由如下方式量测每一牙齿的移动量:先作为参照去掉移动量大于标准偏差而高于或低于全部牙齿移动平均量的牙齿移动(由当前阶段与前一阶段之间的位置差确定)。 When you select the option "statistical filtering," the amount of movement by way of overlapping tools to measure each tooth as follows: first, as a reference to remove the movement is greater than the standard deviation above or below the moving average amount of all dental tooth movement (by The current position and the previous phase difference between the determined phase). 然后,选择其余牙齿作为参照而量测每一牙齿的移动。 Then, select the remaining teeth as the reference and measuring movement of each tooth.

[0055] 图IB显示一个或多个牙具的性能分析。 Performance analysis of one or more teeth with the [0055] Figure IB is displayed. 在散布图中,相对于「目标」移动绘制出所「实现」的移动,并产生趋势线。 In the scattergram, with respect to the "target" mobile draw out movement "realize" and generate trend lines. 图中显示「散布」图以演示「散布」数据点的位置,并产生趋势线以显示牙具的性能。 The figure shows "scatter" in FIG demonstrate "spreading" position data points, and to produce a trend line of teeth with display performance. 在一实施例中,趋势线选择为线性趋势线(其可为曲线);如此,趋势线是所有「散布」数据的最佳拟合直线。 In one embodiment, the trend line is selected as a linear trend line (which may be curved); thus, the trend lines are all "spread" data, the best fit straight line. 矫正器的性能表示为趋势线的斜率。 The performance of the correction is expressed as the slope of the trend line. Y轴截距是模拟当佩戴矫正器时所发生的偶然移动。 Y-axis intercept is simulated when worn aligner occurred accidentally displaced. 可预测性是由R2进行量测,R2是由「实现」数据和「目标」数据的回归计算而获得。 Predictability were measured by R2, R2 is obtained from "achieve" regression calculation data and "objective" data.

[0056] 图IC显示一个数据挖掘系统实施例中使用的各种移动型数据。 [0056] Figure IC a portable display various data used in the example embodiment of a data mining system. 例示性数据集覆盖:扩张/收缩(+/-X平移)、近中/远中(+/-Y平移)、下压(-Z平移)、突出(+Z平移)、 倾倒/成角(X转动)、转矩/倾斜(Y转动)及纯转动(Z转动)。 Exemplary datasets covering: expansion / contraction (+/- X translation), mesial / distal (+/- Y translation), under the pressure (-Z translation), highlight (+ Z translation), dumping / angled ( X rotation), Torque / tilt (Y rotation) and a pure rotation (Z rotation).

[0057] 图ID显示一个或多个牙具的性能分析。 Performance analysis of one or more teeth with the [0057] Figure ID is displayed. 对于图ID中所示的运动类型,所实现的运动是该特定数据集的目标运动的约85%。 For sports type shown in Figure ID, the movement is achieved about 85% of the specific target motion data set.

[0058] 如图ID中显著的显示,在诸多阶段处,实际的牙齿移动一般都会滞后于目标牙齿移动。 [0058] Figure ID is displayed significantly, in many stages of the actual tooth movement generally lags behind the target tooth movement. 在藉由串接的聚合物器具进行治疗的情形下,该种滞后在治疗设计中起到重要作用, 此乃因牙齿移动及负面结果(患者的不适)两者肯定会随差异程度的不同而不同。 In the case of the appliance by a polymer series for treatment, the kind of hysteresis play an important role in the design of the treatment, which was due to the results of tooth movement and negative (patient discomfort) both will certainly vary depending on the degree of difference and different.

[0059] 在一实施例中,藉由考量目标牙齿位置与实际牙齿位置的统计偏差,如步骤170(图2A)和步骤232(图2B)中的临床参数便更加准确。 [0059] In one embodiment, the target tooth by considering the statistical deviation of the actual position and the position of the teeth, as in step 170 (FIG. 2A) and step 232 (FIG. 2B) in the clinical parameters will be more accurate. 例如,由于当前的目标移动未充分实现的计算概率很大,因此可减少后续的移动目标,因而导致后续移动阶段需完成为先前阶段既定的工作量。 For example, due to calculate the probability of the current movement is not sufficient to achieve the goal of a large, thus reducing follow a moving target, resulting in a subsequent move to the previous stage, complete stage given workload. 类似地,目标移动可能尤其在先前阶段中超越合意位置,使得预期的实际移动得到更佳的控制。 Similarly, the target may move beyond especially desirable position in the previous stage, so that the expected actual movement be better controlled. 该实施例牺牲最小化来回移动时间的目标,以换取实现目标末尾阶段结果的较高概率。 This embodiment minimizes the expense of target moves back and forth time in exchange for a higher probability to achieve the target end of the stage results. 该方法是针对若干类似患者案例的群组在治疗计划内达成。 This method is reached within a treatment plan for a number of similar cases in the group of patients.

[0060] 表1显示一实施例中的牙齿分组。 [0060] Table 1 shows an example embodiment of a packet in the teeth. 表2中指示牙齿移动的符号约定。 Table 2 indicates the sign convention tooth movement. 表3中演示所选60个牙弓的不同牙齿移动,其中性能以降序分类。 Table 3 demonstrates the selected 60 different arch tooth movement, which in descending classification performance. 器具性能可分为4个单独的组:高(79-85% )、平均(60-68% )、低于平均(52-55% )以及不足(24-47% )。 Equipment performance can be divided into four separate groups: high (79-85%), average (60-68%), lower than the average (52-55%) and low (24-47%). 表4显示移动可预测性的排名。 Table 4 shows the ranking of the mobile predictability. 可预测性分为3组:高预测性(0. 76-0. 82)、可预测性(0. 43-0. 63)及不可预测性(0. 10-0. 30)。 Predictability divided into three groups: high predictability (76-0 82 0.5.), Predictability (0.5 43-0 63) and unpredictability (0.5 10-0 30). 对于特定的数据集,例如,研究结果如下: For a particular data set, for example, results are as follows:

[0061] 门牙下压和前牙下压性能为高性能。 [0061] and the front incisor teeth under pressure for performance under pressure performance. 门牙下压的范围约为1. 7mm,且前牙下压的范围约1. 7mm。 Lower incisors pressure range of about 1. 7mm, lower front teeth and the pressure range of about 1. 7mm. 这些移动可预测性高。 These mobile high predictability.

[0062] 犬牙下压、门牙转矩、门牙转动及前牙转矩性能为平均性能。 [0062] Under pressure canines, incisors torque, rotation and front incisor teeth torque performance for average performance. 犬牙下压的范围约为1. 3mm,门牙转矩的范围约为34度,门牙转动的范围约为69度,且前牙转矩的范围约为34 度。 Under the canines pressure range of about 1. 3mm, incisors torque range of about 34 degrees, incisor rotation range of about 69 degrees, and the range of torque front teeth about 34 degrees. 该等移动或为可预测,或为高预测性。 Such as mobile or predictable, or high predictability.

[0063] 双尖牙倾倒、双尖牙近中、白齿转动及后牙扩张性能低于平均。 [0063] bicuspid dumped nearly bicuspid, the white teeth and posterior rotation expansion performance below average. 双尖牙近中的范围约为1毫米,双尖牙倾倒的范围约为19度,臼齿转动的范围约为27度,且后牙扩张的范围约为2. 8毫米。 Bicuspid near the range of about 1 mm, bicuspid dumping range of about 19 degrees, molar rotation range of about 27 degrees, and the posterior expansion of the range of about 2.8 mm. 双尖牙倾倒和双尖牙近中为不可预测移动,而其余为可预测移动。 Bicuspid dumping and bicuspids nearly as unpredictable movement, while the rest is predictable move.

[0064] 前牙和门牙突出、圆齿和双尖牙转动、犬牙倾倒、白齿远中以及后牙转矩性能为不足性能。 [0064] prominent front teeth and incisors, round teeth and bicuspids rotation, canines dumping, white teeth distal and posterior torque performance is inadequate performance. 前牙突出的范围约为1.7毫米,门牙突出的范围约为1.5mm,圆齿转动的范围约为67度,双尖牙转动的范围约为63度,犬牙倾倒的范围约为26度,臼齿远中的范围约为2毫米,且后牙转矩的范围约为43度。 Prominent front teeth range of about 1.7 mm, prominent front teeth range of about 1.5mm, scalloped rotation range of about 67 degrees, premolar rotation range of about 63 degrees, canines dumped about 26 degrees range, molars far in the range of about 2 mm, and the posterior teeth torque range of about 43 degrees. 除双尖牙转动为可预测移动(但其产生的性能较低)的外,所有该等移动皆为不可预测移动。 Except bicuspid rotation for predictable move (but it produces lower performance) is, all those moving are all unpredictable movement.

[0073] 在一实施例中,可运用数据驱动分析器。 [0073] In an embodiment, may use the data driven analyzers. 该等数据驱动分析器可包含多种模型,如参数统计模型、非参数统计模型、集群模型、最邻近模型、回归方法以及工程设计(人工)神经网络。 These data may contain a variety of model-driven parser, such as parametric statistical model, nonparametric statistical model, the cluster model, the nearest neighbor model, regression methods and engineering (artificial) neural network. 在作业的前,使用一个或多个训练对话来建立数据驱动分析器或模型。 Before operations, the use of one or more training session to establish a data driven analyzers or models. 用以在该等回话中建立分析器或模型的数据通常被称为训练数据。 Analyzer or model used to establish such answer data is often referred to as training data. 由于是藉由仅检查训练实例的方式来开发数据驱动分析器,因而训练数据的选择会显著地影响数据驱动分析器的准确性及学习速度。 Because it is only checked by way of training examples to develop data-driven analyzer, and thus select the training data can significantly affect the accuracy of the analyzer and the data driver learning speed. 一种以前使用的方式会产生称为用于训练目的的测试集的单独数据集。 One way to generate previously used separate data set is called for training purposes of the test set. 该测试集用以避免模型或分析与训练数据的过度拟合。 The test set is used to avoid over-fitting model or analysis of training data. 过度拟合是指分析器过度存储训练数据, 以致于其无法拟合或分类不可见数据。 Overfitting refers to the excessive storage of training data analyzer that can not fit or classify their data is not visible. 通常而言,在分析器或模型的构造期间,利用测试集对分析器的性能进行测试。 Typically, during construction analyzer or model, using a test set to test the performance of the analyzer. 重复地实施分析器或模型参数的选择,直至分析器在对测试集进行归类方面的性能到达最佳点为止。 Repeatedly implemented to select the analyzer or model parameters, until the parser to classify test set to reach the best performance in terms of the point reached. 此时,训练过程完成。 At this point, the training process is complete. 作为使用独立训练及测试集的替代方案是使用称为交叉验证的方法。 As the use of independent training and test sets alternative is to use a method called cross-validation. 交叉验证可用以为参数分析器确定参数值,或为非参数分析器确定模型。 Cross-validation parameter analyzer that can be used to determine the parameter values, or non-parametric analyzer to determine the model. 在交叉验证中,选择一个训练数据集。 In cross-validation, select a training data set. 接下来,藉由在重复过程中向分析器提交作为测试集的训练数据的不同部分,由此建立多个不同的分析器或模型。 Next, as submitted by the test set of training data to different portions of the analyzer in the repeated process, thereby establishing a plurality of different analyzers or models. 然后,基于所有模型或分析器的组合性能,确定参数或模型结构。 Then, based on the combined performance of all models or analyzer, determining the model parameters or structure. 根据交叉验证方法,通常地, 使用确定的最佳模型结构,用数据再次对分析器或模型进行训练。 Based on cross-validation method, typically, the best use of the model structure determined by data analyzer or model train again.

[0074] 在一实施例中,数据挖掘软件3(图1A)可为在数据库2(图1A)上抓取用于索引的数据的「蜘蛛」或「爬虫」。 "Spider" or "crawler" [0074] In one embodiment, the data mining software 3 (FIG. 1A) may be crawled on the database 2 (FIG. 1A) is used to index data. 在一实施例中,实施集群作业以探测数据中的模式。 In one embodiment, the Cluster operations to detect patterns in the data. 在另一实施例中,使用神经网络来辨识每一模式,此乃因神经网络在辨识牙科治疗模式方面具有很强的健硕性。 In another embodiment, the use of neural networks to identify each mode, which was due to the neural network has a strong resistance in identification of strong dental treatment modalities. 一旦治疗特征得到表征,则神经网络将输入的牙科信息与神经网络辨识器所知的治疗词汇表的存储模板进行对比。 Once the treatment characteristics obtained characterize the neural network storage template input dental information and neural network identifier known therapeutic vocabulary comparison. 除其他以外,辨识模型可包括:隐藏式马可夫模型(Hidden Markov Model, HMM)、动态程序化模型、神经网络、模糊逻辑、或模板匹配器。 Among other things, the identification model may include: hidden Markov model (Hidden Markov Model, HMM), dynamic program model, neural networks, fuzzy logic, or template matcher. 该等模型可单独使用或可组合使用。 These models may be used alone or in combination. [0075] 动态程序化考量了经由N个点的M个「帧」(frame)的所有可能路径,为达成自任一给定帧k的任一点i至下一帧k+Ι的任一点j的过渡,需付出指定的代价。 [0075] dynamically programmed via the M considered a "frame" (frame) of all possible paths of N points, to reach a given frame k himself any arbitrary point i to the next frame k + Ι point j, transition, you need to pay the price specified. 由于当前点至下一点的最佳路径独立于该点以外所发生的事件,因而经由i(k)结束于j(k+l)的路径的最小总体代价[i(k),j(k+l)]是其自身过渡的代价加上通往i(k)的最短路径的代价。 Due to the current point to the next point of the best path is independent of the events that occur outside of that point, and therefore the minimum overall cost via i (k) ends at j (k + l) of the path [i (k), j (k + l)] is its cost plus the cost of the transition leading to i (k) of the shortest path. 优选地,可将前趋路径值保存在MXN阵列中,且可将累计代价保存在2XN阵列中以便包含前一个可能的相邻列和当前列的累计代价。 Preferably, the value stored in the predecessor path MXN array, and the cost can be accumulated before storage in 2XN to include an array of adjacent columns may be accumulated cost and the current column. 然而,该方法需要相当的计算资源。 However, this method requires considerable computing resources.

[0076] 动态程序化要求巨大的计算量。 [0076] dynamic procedural requirements of the huge amount of computation. 为使辨识器找到帧序列与节点模型序列之间的最佳时间对准,其必须参照多个节点模型对大多数帧进行比对。 In order to find the optimal time frame identifier sequence between the nodes and the model sequence alignment, it must be compared to the majority of the reference frame model of multiple nodes. 降低动态程序化所需的计算量的一种方法是使用修剪。 Required to reduce the dynamic of a programmed calculation method is to use pruning. 若该比对的局部概率值低于给定阈值,修剪则会终止参照给定治疗模型对牙科治疗信息的给定部分进行动态程序化。 If the ratio of the partial probability value is below a given threshold, trimming given therapy will be terminated with reference to the model of the dental treatment information given portion dynamically programmed. 此将大大地降低计算。 This will greatly reduce the calculation.

[0077] 隐藏式马可夫模型被视为是动态程序化的一般性概括,在优选实施例中,使用隐 [0077] Hidden Markov model is seen as a dynamic program of general outlines, in a preferred embodiment, the use of hidden

藏式马可夫模型来评价观测序列O (1)、0 (2).....0(t).....O(T)的发生概率,其中每一观 Tibetan Markov model to evaluate the observation sequence O (1), 0 (2) ..... 0 (t) ..... O (T) of the probability of occurrence, in which each concept

测0(t)可为根据VQ方法的离散符号或可为连续向量。 Measuring 0 (t) may be based on a discrete symbol VQ method may be continuous or vector. 可将观测序列的模型建立为下部马可夫链(其带有非直接观测到的状态过渡)的概率函数。 You can model the observed sequence for the lower Markov chain (its state with a non-direct observed transition) probability function.

[0078] 在该优选实施例中,使用马可夫模型,以建立治疗观测序列的概率的模型。 [0078] In the preferred embodiment, the Markov model used to establish the probability of the observation sequence therapeutic model. 状态间的过渡由过渡矩阵A= [a(i,j)l来表示。 Between the transition from the state transition matrix A = [a (i, j) l expressed. 过渡矩阵的每一项a(i,j)是在该模型处于状态i的情形下实现到状态j的过渡的概率。 Each of the transition matrix a (i, j) is the probability to achieve in the case of the model is in state i to state j transition. 该模型的输出符号概率由函数集B = [b(j)]表示,其中输出符号矩阵的项b(j)是在模型处于状态j的情形下以指定值0(t)评价时返回输出观测0(t)的概率的函数。 Output symbol probability of the model set by the function B = [b (j)], where the matrix entry output symbols b (j) is returned to the specified output value 0 (t) evaluated in the case of the model is in a state of observation j 0 (t) the probability function. 该第一状态始终被约束为马可夫链的第一时间帧的初始状态,仅由左至右的状态过渡的规定集为可行。 The first state is always constrained initial state Markov chain first time frames specified set of state transitions only from left to right as possible. 预定的最终状态的定义是无法发生至其他状态的过渡。 Define a predetermined final state transition can not occur to other states.

[0079] 在一实施例中,过渡限制为重新输入状态或条目至下两个状态中的一个。 [0079] In one embodiment, the state transition is limited to re-enter or entry to the next two states a. 该等过渡在模型中定义为过渡概率。 Such a transition is defined as the transition probability in the model. 例如,当前具有处于状态2中的特征信号帧的治疗模式重新输入状态2的概率为a (2,2),输入状态3的概率为a (2,3),且输入状态4的概率为a (2,4) =la(2,2)-a(2,3)。 Treatment mode characteristic of the signal frame, for example, is currently in a state of 2 in having to re-enter state probability 2 is a (2,2), the probability of the input state 3 is a (2,3), and the probability that the input state is a 4 (2,4) = la (2,2) -a (2,3). 输入状态1的概率a (2,1)或输入状态5的概率a (2,5)为0,且概率a(2,1)至a(2,5)的和为1。 1, the input state probability a (2,1) or input state 5 the probability a (2,5) is 0, and the probability of a (2,1) to a (2,5) and is 1. 尽管优选实施例将流程图限制于当前状态或限制于下两个状态,熟悉此项技术者仍可藉由更加灵活的过渡限制来建立HMM模型,但自任何状态发生的过渡的全部概率的和仍为1。 Although the preferred embodiment will be limited to the current state of a flow chart or restrict at two states, those skilled in the art can still be more flexible transition restrictions established HMM model, but all of the probability of transition from any state occurs and still 1.

[0080] 在模型的每一状态j中,可藉由预定义输出符号集中的一个来识别当前特征帧, 或以概率的方式对其进行标记。 [0080] In each state j of the model, can be predefined by a set of output symbols to identify the current feature frame, or probabilistic manner be labeled. 在该情形下,输出符号概率b(j) (0(t))对应于特征帧符号为o(t)的模型所指派的概率。 In this case, the output symbol probability b (j) (0 (t)) corresponds to the feature frame symbol probability o (t) of the model assigned. 模型的排列是过渡概率的矩阵A= [a(i,j)]以及计算B = [b(j) (0(t))]的技术。 Arrangement model are the transition probability matrix A = [a (i, j)] and the calculation B = [b (j) (0 (t))] technology.

[0081] 在一实施例中,马可夫模型由多个训练模式序列形成用于参照的模式,且输出符号概率是多元高斯函数概率密度。 [0081] In one embodiment, the Markov model for the reference pattern is formed by a plurality of sequences of training patterns, and the output symbol probability are multivariate Gaussian probability density function. 牙科治疗信息传递穿过特征提取器。 Dental treatment information transfer through the feature extractor. 在学习期间,所获得的特征向量串列由参数估计器处理,该参数估计器的输出提供至隐藏式马可夫模型。 During the study, the feature vector obtained by serial processing parameter estimator, which provides an output parameter estimator to hidden Markov models. 隐藏式马可夫模型用以参照模式模板集,每一模板代表参照治疗模式的词汇集当中的一个识别模式。 Hidden Markov model to reference mode template set, each template representative reference treatment patterns among a set of vocabulary recognition mode. 接下来,利用马可夫模型参照模板,以基于由每一马可夫模型参照模式模板产生观测的概率,将观测序列归类到参照模式中的一个内。 Next, use the reference template Markov model, based on probabilistic Markov model generated by each reference pattern template observation, observation sequence will be classified into one of the internal reference mode. 在辨识期间,则可将未知的模式识别为在可能性计算器中概率最高的参照模式。 During recognition, pattern recognition may be unknown to the possibility of referring the highest probability calculator mode.

13[0082] HMM模板具有多个状态,每一状态皆具有一个离散值。 13 [0082] HMM template having a plurality of states, each state having both a discrete value. 然而,由于治疗模式特征可具有对比于单个值的动态模式,因而在一实施例中,于HMM的前端处添加神经网络可能够以动态值表示各状态。 However, due to the characteristics of the treatment mode in contrast to the dynamic mode may have a single value, which in one embodiment, the distal end is in the HMM neural network may be able to add dynamic values represent each state. 神经网络的输入层包括输入神经元。 The input layer of the neural network includes input neurons. 输入层的输出分配至中间层内的所有神经元。 Output of the input layer is distributed to all neurons of the intermediate layer within. 类似地,中间层的输出分配至所有输出神经元,该等输出神经元与HMM的内部状态一一对应。 Similarly, the output of the intermediate layer is assigned to all the output neuron, the internal state of these output neurons and the HMM-one correspondence. 然而,每一输出皆具有相对于其自身或相对于其他输出的概率,因此形成修改的HMM。 However, each output has its own probability or both relative to the other with respect to its output, thereby forming a modified HMM. 由此形成的HMM的每一状态皆能回应于特定的动态信号,因而得到更为健硕的HMM。 Each state of the HMM have encountered thus formed in response to a specific dynamic signals, and thus be more strong build HMM. 作为另一选择,神经网络可单独使用,而无需求助于HMM架构的过渡概率。 Alternatively, the neural network can be used alone, without resorting to the transition probability HMM architecture.

[0083] 图IA的输出流或结果4用作反馈,由此改善牙具的设计及/或医师对牙具的使用。 [0083] Figure IA output stream or result 4 is used as feedback, thereby improving the teeth with the design and / or physician's use of dental appliances. 例如,数据挖掘结果可用以基于阶段性方法来评价性能,用以基于治疗方法对器具性能指数进行对比,并用以评价性能由此对比牙齿上的不同附件形状和位置。 For example, data mining results can be evaluated based on the performance of a phased approach to treatments based on instrument performance index compared, and thereby to evaluate the performance comparison of different shape and position of attachment on the teeth.

[0084] 由于能针对庞大的治疗结果群组研究对于牙齿的具体功效及产品性能,因而能在两个或更多个案例群体之间作出统计显著的对比。 [0084] Due to the huge energy for therapeutic efficacy results of cohort studies and product performance for specific teeth, which can make a significant statistical comparison between groups of two or more cases. 倘若所研究的两个群组在治疗方法、器具设计或制造协定方面存在差异,则数据输出所呈现的在产品性能方面的差异可归因于方法、设计或制造协定。 If the two groups studied in treatment methods, apparatus design or manufacturing differences aspect agreement, then the output difference data presented in product performance can be attributed to the method, design or manufacturing agreements. 该最终结果是一种反馈机制,其使得临床医师或制造商能够基于样本尺寸相当庞大的性能数据、使用客观的可量测数据来优化产品设计以及使用。 The end result is a feedback mechanism, which allows the clinician or manufacturer can be based on a sample size of the enormous performance data can be measured using objective data to optimize product design and use.

[0085] 正畸治疗理论并未达成统一的认识,且实际治疗及结果受到附加不确定因素的限制,该等不确定因素为患者变数的量测、与未量测的患者变数的关系、以及患者遵循程度不同。 [0085] orthodontic treatment did not reach a common understanding of the theoretical and practical treatment and outcome are limited additional uncertainties, such as measurement uncertainty patient variables, the relationship between patient variables are not measured, and patient follow different degrees. 因此,不同的临床医师可能针对一个患者优选不同的治疗计划。 Therefore, different clinicians may for a patient is preferably different treatment plans. 因此,一个治疗计划可能并未为所有临床医师所接受,此乃因没有为所有人统一接受的「正确」治疗计划。 Therefore, a treatment plan may not be accepted by all clinicians, which was accepted because there is no unified for all of the "right" treatment plan.

[0086] 藉由针对临床医师的偏好定制治疗参数,接下来的几个实施例可达成临床医师及患者的更佳满意度。 [0086] By preference customize treatment parameters for the clinician, the next few embodiments may achieve better clinician and patient satisfaction. 该系统藉由以统计方式观测临床医师的治疗历史,由此探测治疗偏好方面的差异。 The system is statistically observation by clinicians treating history, thus detect treatment differences in preference. 例如,在牙齿相对拥挤的情形下,临床医师会实施双尖牙拔除的可能性会不同。 For example, in the case of relatively crowded teeth, the clinician will implement the possibility bicuspid removal will be different. 即使当不具备关于给定临床医师的过往治疗的充分记录时,仍可对其他预测变量(如地理位置、与训练相关的变量或行医经验和性质)实施集群,以统计观测治疗参数的显著差异。 Even when not have adequate records for a given clinician's past treatment, still on the other predictor variables (such as geographic location, and training related variables or practice experience and nature) to implement clustering, statistical observation of significant differences in treatment parameters .

[0087] 数据挖掘可发现不同临床医师针对可比对患者实现的不同治疗结果的统计显著模式。 [0087] Data mining can be found in different clinicians for comparable statistics for different patient outcomes achieved significant patterns. 例如,集群在一起的患者案例可相对于不使用集群技术的临床医师系统地减少并发症。 For example, the case of the patient with respect to cluster together can not use cluster technology clinicians systematically reduce complications. 数据挖掘工具所探测的该种差异可用作反馈给更多行医经验不足的临床医师的标记, 并且还可用作向行医经验丰富的临床医师恳求其使用的治疗差异的标记。 Data mining tools can be used to detect differences in the kinds of feedback to the more inexperienced mark practicing clinicians, and can also be used to practicing clinicians experienced plea marked differences in their therapeutic use.

[0088] 在一实施例中,集群技术与先前完成的案例配合使用,以对治疗并发症及结果进行分类。 [0088] In one embodiment, the clustering technique and with the use of previously completed case, for the treatment of complications and to sort the results. 然后,在每一群组内建立风险概率模型。 Then, establish a risk probability model within each group. 然后,基于治疗前变量的相似性,将新案例分配至相同的群组。 Then, based on the similarity of pre-treatment variables, assign the new case to the same group. 然后,将治疗完成后的每一患者群组内的风险与新案例配合使用,以预测治疗结果及并发症的风险。 Then, the risks associated with new cases each patient group after treatment is completed within conjunction to predict treatment outcome and the risk of complications. 然后,对高风险患者加以标记以引起特别注意,可能地包括治疗计划中的附加步骤或附加的临床干扰。 Then, mark it for high-risk patients be given special attention, the treatment plan may include the additional step or additional clinical disturbance.

[0089] 在另一实施例中,按照观测的临床治疗偏好将行医者集群分组,且在每一组中调节治疗参数以更加密切地符合所观测到的治疗偏好。 [0089] In another embodiment, according to the clinical observation of the practitioners prefer cluster packets, and adjusting the treatment parameters in each group in order to more closely conform to the observed treatment preference. 然后,基于与已知治疗历史的群组的已知变量相似性,将没有观测历史的行医者指派成若干组。 Then, based on the known history of the treatment of the group known variables similarity, there will be no history of medical practice observation assignments into several groups.

[0090] 图IE显示用于集群实践的例示性过程。 [0090] Figure IE show illustrative process for cluster practice. 首先,该过程基于临床医师治疗的历史对治疗实践(如治疗偏好、结果及人口统计变量和实践变量)进行集群(20)。 First, the process of treatment based on the historical treatment of clinicians practice (such as treatment preferences, and demographic variables and outcome variables practice) clustering (20). 接下来,该系统建立关于每一群组内的优选临床约束的模型(22)。 Next, the system model of the preferred clinical constraints within each group (22). 接下来,该系统基于人口统计变量及实践变量将没有治疗历史的临床医师指派至20中的群组(24)。 Next, the system is based on demographic variables and no treatment history variables practice clinicians assigned to 20 groups (24). 在一实施例中,该系统使用针对群组的临床约束(26)在每一群组内单独实施过程100 (参见图2A)。 In one embodiment, the system uses the constraint against clinical group (26) within each group in a separate embodiment of the process 100 (see FIG. 2A). 另外,该系统会随到达的新治疗数据和结果数据而更新群组和群组指派(28)。 In addition, the system will treat with the arrival of new data and update data and results and group assignment group (28).

[0091] 图IF显示数据挖掘系统产生建议治疗的另一实施例。 [0091] Figure IF display data mining system to produce another embodiment of the proposed treatment. 首先,该系统基于详细跟踪数据、诊断、治疗参数和结果以及人口统计变量,识别/集群具有详细跟踪(如多个高解析度扫描)的患者历史(40)。 First, the system is based on detailed tracking data, diagnosis, treatment and outcome parameters and demographic variables and identify / clusters with detailed tracking (such as multiple high-resolution scan) History (40) patients. 在每一群组内,该系统建立关于既定位置与由跟踪数据获得的实际位置间差异的模型(42)。 Within each group, the system is modeled on a predetermined position between the actual position data obtained by tracking the difference (42). 此外,在每一群组内,该系统建立关于特殊非合意结果的风险模型(44)。 In addition, within each group, the system is built on a special non-consensual outcome of the risk model (44). 在集群的第二层处,基于可获得的变量,集群带有较少详细跟踪数据的患者历史。 In the second layer of the clusters, based on the available variables, clusters with less detailed patient history tracking data. 第二层的集群具有足够的局部性,因而可将较多数量的第二层群组中的每一个指派至在40中计算的群组或将其视为新的群组(46)。 The second layer has sufficient localized clusters, which can be a large number of the second layer in the group is assigned to each computed group in 40 or it as a new group (46). 该系统藉由来自步骤46的群组的附加记录对步骤42的模型进行精化(48)。 The system additionally recorded by the group from step 46 to step 42 of model refinement (48). 其亦可藉由来自步骤48的群组的附加记录对步骤44的模型进行精化(50)。 It may also be a group of additional records from step 48 to step 44 the model was refined (50). 在集群的第三层处,然后,该系统基于诊断、人口统计及初始身体检查将新患者指派至步骤46的群组(52)。 In the third layer of the cluster, then the system is based on the diagnosis, demographics and initial physical examination of the new group of patients assigned to step 46 (52). 在每一步骤52的群组内,该系统建立关于既定位置与实际位置之间预期差异的模型(54)。 Each step in the group 52, the system model on the difference between the expected and the actual position of the predetermined position (54). 自步骤54起,该系统在相关处(包括图2B的232 和250)使用经修正的预期位置信息(67)。 Starting from step 54, the system at the relevant places (including 232 and 250 in FIG. 2B) is expected to use the amended position information (67). 另外,在每一步骤52的群组内,该系统建立关于非合意结果风险模型(56)。 In addition, within each group step 52, the system is built on a non-consensual outcome of the risk model (56). 自步骤56起,该系统亦对需要特别注意和临床约束的案例(如在图2B和2A的204和160中)加以标记(69)。 Starting from step 56, the system also requires special attention and clinical constraints cases (as in Fig. 2B and 204 2A and 160) to mark (69). 然后,该过程自订针对每一步骤52的群组的治疗计划(58)。 Then, the process is customized for each step of the group's treatment plan 52 (58). 接下来,该系统重复地收集数据(61),并将数据循环回至识别/集群患者历史(40)。 Next, the system repeatedly collect data (61), and recycled back to the identification data / cluster history (40) patients. 另外,可对群组进行修正及重新指派(63)。 In addition, the group can be corrected and re-assigning (63). 该系统亦连续地识别不具有良好图像的群组,以便进行附加跟踪分析(65)。 The system also does not continuously identified group has a good image, for additional tracking analysis (65).

[0092] 在临床治疗环境中,在牙齿移动可能的每一阶段都获取或处理高解析度的数据并非成本有效的做法。 [0092] In the clinical environment, in every stage of tooth movement may have to obtain or deal with high-resolution data is not cost-effective approach. 例如: For example:

[0093] •患者在各次临床就诊期间可能使用若干个器具。 [0093] • Patients may use several instruments at various clinical treatment period.

[0094] •某个给定患者可能仅提供一组牙齿印模。 [0094] • for a given patient may only provide a set of dental impressions.

[0095] •辐射的问题可能限制使用CT或X射线扫描的次数。 Problem [0095] • radiation may restrict the use of CT or X-ray scans of times.

[0096] •临床医师一般没有时间报告关于每次就诊时每颗牙齿的详细空间信息。 [0096] • Clinicians generally do not have time to report detailed spatial information about each visit each tooth.

[0097] 由于此等和其他限制,必需基于局部信息来设计治疗计划。 [0097] Due to these and other restrictions, based on local information necessary to design a treatment plan.

[0098] 在一实施例中,藉由使患者与收集具备详细跟踪信息的代表性样本之间的预测特征相匹配,由此大致地近似表达丢失的信息。 [0098] In one embodiment, the prediction by the patient with detailed tracking information and collect a representative sample of the match between thus roughly approximated the missing information. 在该情形下,基于预计不良的治疗结果,对患者加以标记以请求跟踪信息,如收集和分析附加的牙齿印模组。 In this case, based on the expected poor treatment outcome, to mark the patient to request tracking information, such as the collection and analysis of additional teeth printing module. 然后,使用获得的信息以精化患者群组以及随后指派至群组的患者治疗。 Then, using the obtained information to refine the patient group and the subsequent treatment of patients assigned to the group.

[0099] 一般而言,使用上述数据挖掘系统,扫描患者数据并对数据进行分析。 [0099] In general, using the data mining system, patient data and the scan data were analyzed. 该系统提出关于治疗计划的建议,供牙科行医者批准。 The system is to propose a treatment plan for dental practitioners approval. 牙科行医者可接受治疗计划或请求对治疗计划进行修改。 Dental practitioners acceptable treatment plan or request to modify the treatment plan. 一旦治疗计划得到批准,便可开始制造器具。 Once the treatment plan is approved, you can start making apparatus.

[0100] 图2A图解例示性过程100的概括性流程,过程100用以定义并产生复位器具,以对患者进行正畸治疗。 [0100] Figure 2A exemplary process flow 100 illustrates a general process 100 for defining and generating a reset appliance, orthodontic treatment to the patient. 过程100包括即将描述的方法,并且过程100适合于本发明的装置。 Process 100 includes a method to be described, and the process 100 is adapted to the apparatus of the present invention. 有利地,该过程的计算步骤是构建为在一个或多个习用数位电脑上执行的电脑程序模块。 Advantageously, the calculating step in the process is to build a computer program modules for execution on one or more conventional digital computers.

[0101] 作为初始步骤,先获取患者牙齿或口组织的模子或扫描(110)。 [0101] As an initial step, first obtain the patient's teeth or mouth tissue mold or scanning (110). 该步骤一般涉及对患者牙齿和牙龈进行取模,且另外或作为另一选择,可涉及蜡咬、直接接触式扫描、X射线成像、层析成像、超声成像以及用于获得关于牙齿、颚、牙龈和其他正畸相关组织的位置及机构信息的其他技术。 This step relates generally to patient teeth and gums modulo, and in addition or as an alternative, may involve wax bite, direct contact scanning, X-ray imaging, tomography, ultrasound imaging, and for obtaining on the teeth, jaw, gums and other orthodontic other relevant organizations and institutions of information technology position. 由以此获得的数据推导出数位数据集,该数位数据集代表患者牙齿和其他组织的初始排列(即,治疗前的排列)。 Data obtained by this digital data set is derived, the digital data set representative of the initial arrangement of the patients teeth and other tissues (i.e., before treatment arrangement).

[0102] 对该初始数位数据集进行处理以对各组织构成进行彼此分段(步骤120),该初始数位数据集可包括来自扫描作业的原始数据以及由该原始数据导出的表面模型的数据两者。 [0102] Each of the initial digital data set is processed to the organizations constituting each segment (step 120), the initial digital data set may comprise raw data from scanning operations and data derived from the raw data of the surface model of the two person. 具体而言,在该步骤中,制作数位表示各牙冠的数据结构。 Specifically, in this step, the production number, indicates the data structure of each crown. 有利地是制作整付牙齿的数位模型,其中包括量测的或推测的隐藏表面和根结构、以及周围骨胳及软组织。 Advantageously make lump sum dental digital models, including hidden surface and root structure measured or inferred, and the surrounding bone and soft tissue.

[0103] 牙齿的合意最终位置(即,正畸治疗合意及既定的最终结果)可由临床医师处以处方的形式接收到,可由基本正畸原则计算而得,或可由临床处方以计算方式推测(步骤130)。 [0103] a desired final position of the teeth (i.e., desirable and established orthodontic treatment final result) calculated by the prescribing clinician impose form received, by the basic orthodontic principles, or may be computationally speculate clinical prescription (step 130). 藉由关于牙齿的合意最终位置及牙齿自身的数位图像的规范,可指定每一牙齿的最终位置和表面几何形状(步骤140),从而在治疗的合意末端(end)处形成完整牙齿模型。 With a desired final position of the teeth and the teeth on its own digital image specification, can specify the final position of each tooth and surface geometry (step 140), so that (end) is formed at the end of a complete dental model in the desirable treatment. 一般而言,在该步骤中指定每颗牙齿的位置。 In general, the specified position of each tooth in this step. 该步骤的结果是数位数据结构集,该数位数据结构集表示经建模的牙齿相对于假设稳定组织的正畸正确复位。 Result of this step is a set of digital data structures, the digital data set represented by the structure of the teeth with respect to the modeling assumptions orthodontic stable organization reset properly. 该牙齿和组织两者皆表示为数位数据。 The two organizations are the teeth and represent several bits of data.

[0104] 具备每颗牙齿的起始位置和最终位置之后,接下来,该过程将定义每颗牙齿运动的牙齿路径。 [0104] After the starting position and the final position have each tooth, next, this process will define tooth paths each tooth movement. 在一实施例中,对牙齿路径进行总体优化,以使牙齿以最快且来回移动量最小的方式移动,以便将牙齿自其初始位置带到其合意最终位置。 In one embodiment, the overall optimization of tooth paths, so that the teeth and the back and forth movement to the fastest way to move a minimum amount, so that the teeth from the initial position to the final position of its desirable. (来回移动是牙齿沿着朝向合意最终位置以外的任何方向的任何移动。有时,必需藉由来回移动方可允许牙齿彼此地移动。)对牙齿路径进行分段。 (Moving back and forth along the teeth to move in any direction toward any location other than the final accord. Sometimes, it is necessary only by moving back and forth to each other to allow the teeth.) Tooth path segment. 对该等区段进行计算,以使区段内的每一牙齿运动皆保持在线性平移和转动平移的阈值极限范围内。 Calculation of such sections, so that each tooth movement within the segment are kept linear translational and rotational translation of the thresholds within limits. 以此方式,每一路径区段的端点皆可构成临床上可行的复位,且区段端点的总和构成临床上可行的牙齿位置序列,由此使得自序列中的一个点至下一个点的移动不会导致牙齿的碰撞。 Endpoint this manner, each path segment constituting Jieke clinically feasible reset, and the sum of the segment end points constitute a viable sequence of tooth positions clinically, thereby enabling the mobile self sequence one point to the next point does not result in a collision of teeth.

[0105] 在一个实施方案中,藉由基于待使用器具的性质的预设值,对线性和转动平移的阈值极限进行初始化。 [0105] In one embodiment, by default based on the nature of the appliance to be used, for linear and rotational translation of the threshold limit is initialized. 可使用针对患者的数据计算更为特别定制的极限值。 Can be used for patient data to calculate a more custom limits. 亦可基于器具计算的结果更新极限值(步骤170,稍后描述),该器具计算可确定:在沿着一个或多个牙齿路径的一个或多个点处,器具所能产生于牙齿和组织之后有构形上的力无法实现一个或多个牙齿路径区段所代表的复位。 Can also be calculated based on the result of the appliance to update the limit value (step 170, described later), this appliance calculation may determine: one or more teeth in a path along one or more points, can be generated by the appliance to the tooth and tissue After the configuration has the force can not be reset one or more teeth path segments represent. 藉由该信息,定义分段路径(步骤150)的子过程可重新计算路径或受到影响的子路径。 With this information, the definition of sub-paths (step 150) of the sub-process can recalculate the affected path or sub-path.

[0106] 在该过程的各阶段,且更具体而言在定义分段路径之后,该过程可以与且一般会与负责患者治疗的临床医师交互作用(步骤160)。 [0106] In the various stages of the process, and more specifically, after defining segmented paths, the process can be, and usually patients and clinicians responsible for the interaction (step 160). 可使用经程序化以接收牙齿位置及模型的客户端进程以及来自伺服电脑或伺服进程(其中构建了过程100的其他步骤)的路径信息来构建临床医师的交互作用。 May be programmed to receive by using tooth positions and models of the client process and the path information from the servo computer or servo process (process steps which construct the other 100) to build clinician interaction. 有利地,客户端进程程序化为允许临床医师显示位置及路径的动画,并允许临床医师重设一个或多个牙齿的最终位置并指定即将施加于分段路径的约束。 Advantageously, the client process is programmed to allow the clinician to display the location and path animation, and allows clinicians to reset the final position of one or more teeth and specify constraints imposed on the upcoming segment of the path. 若临床医师做出任何此等改变,则会再次实施定义分段路径的子过程(步骤150)。 If the clinician to make any such changes will be the implementation of the sub-process definition segmented paths again (step 150).

[0107] 分段牙齿路径以及相关联的牙齿位置数据是用以计算临床上接受的器具构形(或器具构形的接连变化),该器具构形将在路径区段所指定的步骤中沿着定义的治疗路径移动牙齿(步骤170)。 [0107] segmented tooth paths and associated tooth position data are used to calculate the appliance configuration clinically acceptable (or successive changes in appliance configuration), the configuration of the apparatus in the step along the path specified in the section defined treatment path of movement of teeth (step 170). 每一器具构形代表沿着患者治疗路径的一个步骤。 Each appliance configuration representative patients a step along the path. 对该等步骤进行定义及计算,以使每一离散位置可在前一个离散步骤实现的牙齿位置的基础上继而实 The other steps are defined and calculated so that each discrete position can be the basis of a discrete step towards the position of the front teeth and then the real

16现直线牙齿移动或简单转动,且以使每一步骤所需的复位量涉及作用于患者牙系上的正畸最佳力量。 16 straight teeth now move or simply rotate and so each step required to reset the amount involved in acting on the best orthodontic forces on the dentition of patients. 如同路径定义步骤一样,该器具计算步骤亦可包括交互作用且甚至包括与临床医师进行的重复交互作用(步骤160)。 As with the path definition step as the appliance calculation step can include interactions and even repeating the interaction (step 160) and the clinician. 下文将更加完整地描述构建该步骤的过程步骤200 的作业。 Operation process will hereinafter be more fully described in the step of constructing step 200.

[0108] 器具定义经计算之后,过程100可进行至制造步骤(步骤180),其中制造该过程所定义的器具,或产生可由手动过程或自动过程使用的电子信息或列印信息,以定义器具构形或定义器具构形的改变。 [0108] After the appliance is defined by calculation, the manufacturing process may proceed to step 100 (step 180), wherein the manufacturing apparatus as defined in the process, or generate the electronic information or print information may be a manual process or an automated process used to define the appliance configuration define appliance configurations or changes.

[0109] 图2B图解过程200,过程200构建上文提及的美国专利第5,975,893号中所述的该种聚合物壳体矫正器的器具计算步骤(图2A的步骤170)。 [0109] Figure 2B illustrates process 200, process 200 to build the kind of the polymeric shell aligner appliance U.S. Patent No. 5,975,893 referred to above described calculation step (step 170 in FIG. 2A). 该过程的输入包括:初始矫正器形状202、各种控制参数204以及当前治疗路径区段206末端处的牙齿合意末端构形。 Enter the process comprising: an initial aligner shape 202, various control parameters teeth desirable end 204 and the current treatment path segment 206 at the end configuration. 其他输入包括:就位于颚内的牙齿的数位模型、颚组织模型以及关于初始矫正器形状和矫正器材料的规范。 Other inputs include: jaw teeth located within the digital model of the jaw organizational models and specifications on initial corrective braces shape and materials. 使用该输入数据,该过程建立关于矫正器、牙齿和组织(其中矫正器就位于牙齿的上)的有限元模型(步骤210)。 Using the input data, the process of establishing a finite element model on braces, teeth and tissue (including braces on the teeth located) (step 210). 接下来,该过程对矫正器、牙齿和组织的复合有限元模型应用有限元分析(步骤220)。 Next, the process of composite braces, teeth and tissue finite element model of the finite element analysis (step 220). 该分析会一直运行直至到达退出条件,到达退出条件时, 该过程会评价牙齿是否到达当前路径区段的合意末端位置,或其位置是否充分靠近合意末端位置(步骤230)。 When the analysis would have been to run until you reach the exit conditions to reach the exit condition, the evaluation process will reach a desired end position of the teeth if the current path segment, whether or desirable location near full end position (step 230). 若牙齿并未到达可接受的末端位置,则该过程会计算新的候选矫正器形状(步骤240)。 If the tooth does not reach an acceptable end position, the process calculates a new candidate aligner shape (step 240). 若到达可接受的末端位置,则对该有限元分析所计算的牙齿运动进行评价以确定其在正畸术上是否可接受(步骤232)。 If reach an acceptable end position, the motion of the tooth calculated by the finite element analysis was evaluated to determine whether it can accept (step 232) on the orthodontic technique. 若未到达可接受的末端位置,则该过程仍继续进行以计算新的候选矫正器形状(步骤240)。 Failure to reach an acceptable end position, then the process is continuing to calculate a new candidate aligner shape (step 240). 若该等运动在正畸术上可接受且牙齿已到达可接受位置,则对当前矫正器形状与先前计算的矫正器形状进行对比。 If such movement in the orthodontic and dental surgery acceptable has reached an acceptable position, the current aligner shape and the previously calculated aligner shape comparison. 若当前形状是目前为止的最佳解决方案(决定步骤250),则将该形状储存为目前为止的最佳候选(步骤260)。 If the current shape is the best solution (decision step 250) so far, then the shape is stored as the best candidate so far (step 260). 若并非如此,则将其储存在可选步骤中作为可能的中间结果(步骤252)。 If this is not the case, then it is stored in the intermediate result in an optional step as a possible (step 252). 若当前矫正器形状是目前为止的最佳候选,则该过程确定其是否足够好到可接受的程度(决定步骤270)。 If the current aligner shape is the best candidate so far, the process determines whether it is good enough to an acceptable level (decision step 270). 若可接受,则退出该过程。 If acceptable, quit the process. 否则,该过程继续,并计算另一候选形状(步骤240)以供分析。 Otherwise, the process continues and calculates another candidate shape (step 240) for analysis.

[0111] 图3显示过程300,过程300是建立可用以实施过程200 (图2)的步骤210的有限元模型。 [0111] Figure 3 shows the process 300, process 300 is built to implement the process 200 (FIG. 2) of the finite element model can be used in step 210. 模型建立过程300的输入包括描述牙齿和组织的输入数据302及描述矫正器的输入数据304。 Model 300 includes a description of the process input data input data input teeth and tissue is described aligner 302 and 304. 描述牙齿302的输入数据包括:牙齿的数位模型;刚性组织结构的数位模型(若存在);高粘度流体形状和粘度的规范,其建立关于牙齿所嵌入的以及牙齿所连接的基质组织的模型;以及指定模型元件的非移动边界的边界条件。 Description teeth 302 of the input data comprises: teeth digital model; rigid structure of the digital model (if present); Specification for high viscosity fluids shape and viscosity, which build on the teeth are embedded and stromal tissue of teeth of the connected model; non-moving boundary and boundary conditions specified model components. 在一个实施方案中,该等模型元素仅包括:牙齿的模型、高粘度嵌入基质流体的模型以及实际上定义建模流体所盛装的刚性容器的边界条件。 In one embodiment, only those model elements comprising: a teeth model, embedded in a matrix of high viscosity fluid model and actually define the boundary conditions modeling the rigidity of the contained fluid container. 请注意,流体特性可随患者群组不同而不同,如随着年纪不同而不同。 Note that fluid characteristics may differ with the patient groups, such as the different ages and different.

[0112] 建立牙齿及组织的初始构形的有限元模型(步骤310),并且将该有限元模型高速缓存起来,以便在该过程稍后的重复中再次使用(步骤320)。 [0112] finite element model of teeth and tissues initial configuration (step 310), and the finite element model of the cache up to re-use (step 320) in the process is repeated in later. 当牙齿和组织初始构形的有限元模型建立完成时,建立聚合物壳体矫正器的有限元模型(步骤330)。 When the finite element model of teeth and tissue to complete the initial configuration of the establishment, the establishment of polymeric shell appliances finite element model (step 330). 该模型的输入数据包括指定矫正器的制作材料以及矫正器形状的数据(数据输入304)。 Input to the model includes the production of the specified material and aligner aligner shape data (data input 304).

[0113] 然后,对模型矫正器进行计算操控,以便将其放置于模型颚中的建模牙齿上,以建立就位矫正器的复合模型(步骤340)。 [0113] Then, the model aligner is calculated manipulated so as to be placed on the modeling teeth in the model jaw to create a composite model in place aligner (step 340). 可选地,对用以使矫正器(包括任何附连至牙齿的任何硬体)变形从而配合在牙齿上所需的力进行计算并将其用作量测特定矫正器构形的可接受性的质素因数。 Alternatively, in order to make the correction for (including any attachment to any hardware teeth) deformed to fit the desired force on the teeth is calculated and used as a measurement of the specific appliance configuration acceptability The quality factor. 可选地,根据基于治疗前的步骤以及其他患者信息的概率模型,对所使用的牙齿位置进行估计。 Alternatively, according to the pre-treatment step and a probability model based on other patient information, the position of the teeth used to estimate. 然而,在一较为简单的替代方案中,藉由如下方式建立关于矫正器变形的模型:对矫正器内部施加足够大的力以使矫正器大到足以配合在牙齿上;将模型矫正器放置于复合模型中的模型牙齿上;将模型牙齿和组织的条件设为无限刚性;以及允许模型矫正器松弛地进入到固定牙齿上的位置内。 However, in a simpler alternative, by the following manner to establish on the aligner deformation model: internal correction is applied to a sufficiently large force to the aligner is large enough to fit over the teeth; placed in the model aligner composite model model tooth; the condition of the teeth and organizations to model infinite rigid; and allow the model braces loosely into position within the fixed teeth. 建立关于矫正器和牙齿表面的模型,以使该阶段处的交互作用没有摩擦,由此使得矫正器模型实现模型牙齿上的正确初始构形, 之后开始有限元分析以找到关于复合模型的解决方案并且计算牙齿在受到变形矫正器影响下的移动。 Establishment of the braces and tooth surface model to make the interaction at this stage there is no friction, thereby enabling the appliance model to achieve the correct model for the initial configuration on the teeth, after the start of the finite element analysis in order to find solutions to complex model and mobile computing at being deformed teeth aligners impact.

[0114] 图4显示过程400,过程400是用于计算可在过程200 (图2B)的步骤240的矫正器计算中使用的下一矫正器形状。 [0114] Figure 4 shows the process 400, process 400 is used in the next aligner shape can be used in the calculation process 200 (FIG. 2B) is calculated in step 240 in the aligner. 使用各种输入来计算下一候选矫正器形状。 To calculate the next candidate aligner shape using various inputs. 该等输入包括:由复合模型的有限元分析解决方案所产生的数据输入402以及当前牙齿路径所定义的数据404。 These inputs include: the finite element analysis of composite model data solutions generated input data 402 and the current path defined by the teeth 404. 由该有限元分析导出的数据402包括:发生牙齿仿真复位所用的实耗时间量;该分析所计算的实际末端牙齿位置;施加至每一牙齿的最大线性力和扭转力;每一牙齿的最大线速度和角速度。 Derived from the finite element analysis data 402 includes: the amount of real elapsed time used in dental simulation reset occurs; the maximum linear and torsional force applied to each of the teeth;; the actual end tooth positions calculated by the analysis of the maximum of each of the teeth linear and angular velocities. 来自输入路径信息的输入数据404包括:当前路径区段的初始牙齿位置;当前路径区段末端处的合意牙齿位置;每一牙齿的最大允许移位速度;以及每一牙齿的最大允许的每种力。 Input data from the input path information 404 includes: current path segment initial tooth position; the current consensus position of the teeth at the end of the path segments; each tooth of the maximum allowable displacement speed; the maximum allowed, and each tooth of each force.

[0115] 若先前评价的矫正器经发现违反一个或多个约束,则过程400可选地使用附加的输入数据406。 [0115] If a previously evaluated aligner been found to violate one or more constraints, then the process 400 optionally using additional input data 406. 该数据406可包括用以识别先前评价的矫正器违反约束以及任何识别的次佳性能的信息。 The data 406 may include a previous evaluation to identify constraints and braces violate any identifying information of sub-optimal performance. 另外,过程400可使用与先前牙科器件所违反的约束以及其次佳性能有关的输入数据408。 In addition, process 400 may use the good performance of the input constraints, and secondly data associated with dental devices previously violated 408.

[0116] 接收到初始输入数据之后(步骤420),该过程会关于模型中的可移动牙齿进行重复作业。 [0116] After receiving the initial input data (step 420), the process can move on the model teeth repeat jobs. (一些牙齿可能被识别并约束为不可移动。)若由先前所选的矫正器选择的当前牙齿运动的末端位置和动力学为可接受的(决定步骤440的「肯定性」支路),则该过程会继续选择考量下一牙齿(步骤430),直至所有牙齿得到考量(自步骤430至步骤470的「完成」支路)。 (Some of the teeth may be identified and constrained to be non-removable.) If the end position and dynamics of the previously selected aligner currently selected tooth movement is acceptable (decision step 440 of "positive" branch), then This process will continue to choose to consider the next tooth (step 430), until all the teeth to give consideration (from step 430 to step 470 is "Finish" branch). 否则(自步骤440起的「否定性」支路),计算矫正器在当前所选牙齿区域中的改变(步骤450)。 Otherwise (from step "negative" from 440 branch), computing appliance to change the currently selected tooth area (step 450). 如图所述,该过程然后往回移动以选择下一当前牙齿(步骤430)。 As shown, the process is then moved back to select the next current tooth (step 430). 当所有牙齿皆经过考量时,参照先前定义的约束(其实例上文已提述)来评价对矫正器作出的整体改变(步骤470)。 When all the teeth are after consideration, referential constraints previously defined (examples of which have been referred to above) to evaluate the overall changes to the appliance made (step 470). 可参考各种另外的考量(如可制造性)来定义约束。 Refer to a variety of other considerations (such as manufacturability) to define constraints. 例如,可将约束定义为设定矫正器材料的最大或最小厚度,或设定矫正器在牙冠上的最大或最小覆盖度。 For example, the constraint can be defined as a set of braces maximum or minimum material thickness, or set the maximum or minimum braces coverage on the crown. 若满足矫正器约束,则应用改变以定义新的矫正器形状(步骤490)。 If the aligner constraints satisfied, then the application altered to define a new aligner shape (step 490). 否则,修订矫正器的改变以便满足约束(步骤480),并且应用修订的改变来定义新的矫正器形状(步骤490)。 Otherwise, in order to amend the aligner changes satisfy the constraints (step 480), and the revised changes applied to define a new aligner shape (step 490).

[0117] 图5A图解计算当前牙齿区域中的矫正器改变的步骤的一个实施方案(步骤450)。 An embodiment of the [0117] Figure 5A graphically calculate the current dental braces zone change steps (step 450). 在该实施方案中,使用基于规则的推断引擎456以处理先前描述的输入数据(输入454)以及规则库452中的一组规则452a-452n。 In this embodiment, using a rule-based inference engine 456 to process the input data previously described (input 454) and rule base 452 a set of rules 452a-452n. 推断引擎456及规则452定义产生系统,该产生系统当应用于真实输入数据时会产生一组输出结论,该组输出结论会指定对矫正器在当前牙齿区域中的改变(输出458)。 Inference engine 456 and the rules 452 define the generating system, the generating system, when applied to the real input data will produce a set of output conclusions that specify the set of output conclusions will change to the aligner (output 458) in the region of the current tooth.

[0118] 规则452a. . . 452η具有传统的两部分形式:一个定义条件的条件部分;以及一个在条件满足的情形下定义所断言的结论或动作的结论部分。 ... [0118] Rule 452a 452η traditional form of two parts: a definition of conditions as part; and a concluding section under defined conditions are met in the case of the asserted conclusion or action. 条件可为简单的条件,或者可为多个断言的复杂逻辑合取或逻辑析取。 Conditions for simple conditions, or for multiple assertions of complex logic conjunctive or disjunctive logic. 定义对矫正器做出的改变的例示性规则组包括如下:若牙齿运动过快,则反向于运动的合意方向,给矫正器添加驱动材料;若牙齿运动过慢,则添加驱动材料以对牙齿位置进行过校正;若牙齿离合意末端位置过远,则添加进行过校正的材料;若牙齿移动超出合意末端位置过远,则添加在牙齿与矫正器相遇处使矫正器硬化的材料;若添加的驱动材料量到达最大量,则添加用以过校正牙齿复位的材料而不添加驱动材料;若牙齿的运动是沿着合意方向以外的方向,则去除并添加用以使牙齿重新定向的材料。 Change the definition of braces made exemplary set of rules include the following: If the tooth movement is too fast, then back to a desired direction of motion, to add driving material correction; if the tooth movement is too slow, then add the drive for material been corrected tooth position; if the tooth is too far away from the desirable end position, add material been corrected; if tooth movement beyond a desired end position is too far, then add in the teeth with braces braces meet at so hardened material; if drive the amount of material added to reach the maximum amount, then add to reset overcorrection dental materials without adding drive material; if tooth movement is in the direction other than the desirable direction, then removed and added to the tooth material redirected .

[0119] 在图5Β和5C中所示的一个替代实施例中,是计算矫正器的绝对构形,而并非计算增量差异。 [0119] In an alternative shown in FIG 5Β and 5C embodiment, the aligner is calculated absolute configuration, rather than computing the incremental difference. 如图5Β中所示,过程460计算矫正器在当前牙齿区域中的绝对构形。 5Β As shown, process 460 in the current computing aligner tooth region absolute configuration. 使用上文所述的输入数据,该过程是计算合意末端位置与当前牙齿所实现的末端位置之间的差异(462)。 Using the above input data, the process is different (462) calculating a desired end position and the current tooth achieved between the end position. 使用牙齿中心线与牙龈组织水平面的交叉点作为参考点,该过程计算所有6个运动自由度上(即,三个平移度及三个转动度)的差异补充量(步骤464)。 Use dental center line and the intersection of the gingival tissue level as a reference point, the process is calculated on all six degrees of motion (ie, three translational and three rotational degrees degrees) differences supplementary amount (step 464). 接下来,如图5Β中所示,模型牙齿自其合意末端位置移位达补充差异的量(步骤466)。 Next, as shown in FIG 5Β, model tooth from which a desired end position shift amount of supplemental difference (step 466).

[0120] 图5D显示说明性模型矫正器60在说明性模型牙齿62上的平面视图。 [0120] FIG. 5D show an illustrative model aligner 60 in the illustrative model tooth 62. The plan view. 该牙齿位于其合意末端位置,且矫正器形状由该末端位置中的牙齿定义。 The tooth is in its desirable end position, and the aligner shape is defined by the end position of the teeth. 图中显示,有限元分析所计算的牙齿实际运动是将牙齿放置于位置64中,而非放置于合意位置62中。 The figure shows the actual movement of the teeth of finite element analysis calculations are placed in the position of the teeth 64, rather than placed in a desired position 62. 对计算末端位置的补充显示为位置66。 Calculating the end position of the supplementary display for the location 66. 在该过程的重复期间,过程460 (图5Β)的下一步骤按照前个步骤(466)中计算的移位模型牙齿(步骤468)的位置来定义当前牙齿区域中的矫正器。 In repeated during the process, the process 460 (FIG 5Β) of the next step to define the region of the current tooth aligner accordance with the preceding step (466) displaced model tooth (step 468) of the calculated position. 图5D中将当前牙齿区域中计算的矫正器构形显示为由位置66中的复位模型牙齿定义的形状68。 Figure 5D tooth region in the current computed aligner configuration in the shape of the display 66 by the reset position defined model tooth 68.

[0121] 过程460中亦可构建成规则452 (图5Α)的另一步骤显示于图5C中。 Another step [0121] Process 460 may also be constructed to rule 452 (FIG 5Α) is shown in Figure 5C. 为使当前牙齿沿其中心轴线的方向移动,则要将定义矫正器区域的模型牙齿尺寸、或牙齿矫正器中允许的空间量制作得较小,在该过程决定自其移动牙齿的区域(步骤465)。 In order to move the current tooth in the direction of its central axis, the amount of space will have to define the size of the aligner model tooth region, or braces allowed made smaller, the process determines the area from which the movement of the teeth (step 465).

[0122] 如图6中所示,为治疗路径中一个步骤计算矫正器形状的过程200 (图2Β)在过程600中是一个计算一系列矫正器形状的步骤。 [0122] As shown in Figure 6, the process for the treatment of the step of calculating a path aligner shape 200 (FIG 2Β) in a series of process 600 is the step of calculating aligner shapes. 该过程600始于初始化步骤602,其中获得了初始数据、控制值和约束值。 The process 600 begins with an initialization step 602, wherein obtaining the initial data, the control value and the constraint value.

[0123] 当找出每一步骤或治疗路径中每一区段的矫正器构形(步骤604)时,过程600确定所有矫正器是否为可接受矫正器(步骤606)。 [0123] When the paths to identify each step or each treatment zone aligner configuration (step 604), the process 600 determines whether all the aligners are acceptable aligner (step 606). 若为肯定性结果,则该过程完成。 If the result is affirmative, then the process is completed. 否则,该过程可选地会采取一组步骤610,试图计算一组可接受的矫正器。 Otherwise, the process optionally can take a set of steps 610, attempting to calculate a set of acceptable aligners. 首先,放松对矫正器的一个或多个约束(步骤612)。 First, the relaxation of one or more of the aligner constraints (step 612). 然后,对于带有不可接受矫正器的每一路径区段,透过新的约束来实施确定矫正器形状的过程200 (图2B)(步骤614)。 Then, for each path segment with an unacceptable aligner, through the implementation of new constraints to the process of determining the shape of the aligner 200 (FIG. 2B) (step 614). 若所有矫正器都变为可接受,则退出过程600 (步骤616)。 If all appliances have become acceptable, then exit process 600 (step 616).

[0124] 矫正器可因各种原因而成为不可接受矫正器,其中一些原因由该过程处理。 [0124] correction can be due to various reasons, become unacceptable aligners, which for some reason is handled by the process. 例如, 若要求任何不可行的移动(决定步骤620),S卩,若要求形状计算过程200 (图2B)实现某个没有任何可用规则或可用调节的运动,则过程600会进而执行一个模块,该模块会计算受体牙齿的硬体附件构形,由此力可施加至该受体牙齿以实现所要求的运动(步骤640)。 For example, if the request of any mobile infeasible (decision step 620), S Jie, if desired shape calculation process 200 (FIG. 2B) can be used to achieve a no rule or regulation of movement available, the process 600 may further execute a module, The module calculates the receptor dental attachment hardware configuration, whereby the force may be applied to the receptor in order to effect movement of the tooth (step 640) required. 由于添加硬体可具有更为局部的效果,因此当将硬体添加至模型时,再次执行过程600的外部循环(步骤642)。 Because adding hardware can have a more localized effect, and therefore when the hardware added to the model, the outer loop process 600 performed again (step 642).

[0125] 若并未要求任何不可行移动(步骤620的「否定性」支路),则过程将控制转移到路径定义过程(如图2A的步骤150),以重新定义治疗路径中具有不可接受矫正器的彼等部分(步骤630)。 [0125] If the move does not require any feasible (step "negativity" branch 620), the process to transfer control to the path definition process (Figure 2A step 150), in order to redefine the treatment path having unacceptable their part of the appliance (step 630). 该步骤可包括:改变牙齿运动的增量(即,改变治疗路径上的分段)、改变治疗路径中一个或多个牙齿所遵循的路径或该两者。 This step may include: changing the incremental movement of the teeth (i.e., changing the segmentation treatment path), a path or change the treatment path followed by a plurality of teeth, or both. 在治疗路径经重新定义之后,再次执行该过程的外部循环(步骤632)。 After the re-definition of the treatment path, perform the outer loop of the process again (step 632). 有利地,该重新计算局限于仅重新计算治疗路径的重新定义部分上的矫正器。 Advantageously, the recalculated confined to recalculate appliances redefine the path on the part of the treatment. 若所有矫正器皆变为可接受矫正器,则退出该过程(步骤634)。 If all appliances are appliances become acceptable, then quit the process (step 634). 若仍存在不可接受的矫正器,则可重复该过程,直至找到一组可接受矫正器或超过重复的极限(步骤650)。 If there is still an unacceptable aligner, the process may be repeated, until it finds a set of acceptable aligners or exceeds the limit repeated (step 650). 在该点处以及在该等过程中描述于该规范中的其他点处(如在计算附加硬体(步骤640)处),该过程可与操作人员(如临床医师或技术员)交互作用以请求帮助(步骤652)。 At this point and in such process is described in the specification of the other points (such as in the calculation of the additional hardware (step 640) at), the process can be used with the operator (e.g., clinician or technician) to request interaction Help (step 652). 操作者可提供的帮助可包括:定义或选择附连至牙齿或骨骼的适合附件;定义附加的塑形元件,以为治疗路径的一个或多个区段提供所需的力;建议更改治疗路径,或更改牙齿的运动路径或更改治疗路径的分段;及批准操作约束的某一偏差或放松操作约束。 Help operator can provide may include: define or select attached to the teeth or bone for attachment; define additional shaping element, that one or more segments of the treatment path provides the force required; recommended to change the treatment path, or change the path of movement of the teeth or change the treatment path segment; and a deviation or operating constraints relax approved operational constraints.

[0126] 如上所提及,过程600由各输入数据项来定义和参数化(步骤602)。 [0126] As mentioned above, the process 600 is defined by the input data item and parameter (step 602). 在一个实施方案中,该初始化和定义数据包括如下各项:总体过程的外部循环的重复极限;关于质素因数的规范,质素因数经计算以确定矫正器是否足够好(参见图2B,步骤270);关于矫正器材料的规范;关于矫正器形状或构形必须满足为可接受的约束规范;关于力和定位运动及速度要在正畸术上为可接受的规范;初始治疗路径,其包括每一牙齿的运动路径及将治疗路径分为若干区段的分段方式,其中每一区段由一个矫正器来达成;关于任何安装在牙齿上或其他物体上的锚定件的形状或位置的规范;以及关于牙齿所处的颚骨和其他组织的模型规范(在该所述实施方案中,该模型由牙齿所嵌入的粘性基质流体模型构成,且该粘性基质流体具有实质上定义流体容器的边界条件)。 In one embodiment, the initialization and definition data comprising the following: repeat the limit of the outer loop of the overall process; the specification about the quality factor, the quality factor is calculated to determine aligner is good enough (see Fig. 2B, step 270) ; standardize on braces materials; about aligner shape or configuration of the constraints that must be met for an acceptable norm; on the force and speed of movement and positioning on orthodontic surgery to be an acceptable norm; initial treatment path, including each the path of movement of a tooth and the treatment path into several sections of piecewise fashion, wherein each segment consists of a corrective device to reach; anchor on any shape or position or other object mounted on the teeth specification; and on the teeth which the jawbone and other organizations model specification (in the described embodiment, the model consists of a matrix of teeth embedded viscous fluid model constitution, and the viscous fluid has essentially define the matrix fluid container boundary conditions).

[0127] 图7是统计根模型的例示性图表。 [0127] FIG. 7 is an exemplary diagram statistical root model. 如图中所示,使用上述扫描过程,识别牙齿的扫描上部部分701。 As shown, using the above scanning process, the identification portion 701 scans an upper tooth. 然后,给扫描上部(包括牙冠)增补上建模的3D牙根。 Then, to scan the upper part (including crown) on the addition of 3D modeling roots. 可以统计方式建立关于牙根的3D模型。 You can build a 3D model on the root of statistical methods. 牙根702的3D模型及上部700的3D模型一同形成牙齿的完整3D 模型。 Root 702 3D models and 3D models of the upper 700 together form a complete 3D model of the teeth.

[0128] 图8显示使用附加牙科信息而得到增强的牙根建模的例示性图表。 [0128] Figure 8 shows an exemplary chart obtained by enhanced root modeling using additional dental information. 在图8中,附加的牙科信息是χ射线信息。 In Figure 8, the additional dental information is χ-ray information. 对牙齿的X射线影像710进行扫描,以提供完整牙齿形状的2D 视图。 The X-ray image of the tooth 710 is scanned to provide a 2D view of the complete tooth shapes. 在X射线影像中识别目标牙齿的轮廓。 Identifying target tooth contour in X-ray images. 根据附加信息,修改图7中形成的模型712。 According to the additional information model, modify the formation 712 in FIG. 7. 在一实施例中,图7的牙齿模型经形态转换,从而形成与X射线数据相符的新模型714。 In one embodiment, the dental model form in FIG. 7 by the conversion, so as to form in line with the X-ray data of the new model 714.

[0129] 图9显示牙齿CT扫描的例示性图表。 [0129] Figure 9 shows exemplary diagrams of CT scan of teeth. 在该实施例中,直接由患者的高解析度CBCT 扫描导出牙根。 In this embodiment, directly from the high-resolution CBCT scan of the patient derived root. 然后,可将扫描的牙根应用到由印模导出的牙冠,或可将扫描的牙根与自锥 May then be applied to the scanning teeths crowns derived from an impression, or it may be scanned and self tapered root

[0130] 在一实施例中,锥束X射线源及2D区域探测器藉由各种方法中的任一种对患者牙科解剖结构进行扫描(优选地,是在360度角范围上及其整个长度上进行扫描),在该各种方法中,区域位置探测器相对于X射线源是固定的,且扫描是由X射线源与物体之间的相对转动和平移移动来提供(辐射源对物体进行照射)。 [0130] In one embodiment, the cone beam X-ray source and a 2D area detector by any one of various methods of dental patient anatomy is scanned (preferably, in the range of 360 degrees and the entire scan) on the length, in the various methods, the area of the position detector with respect to the X-ray source is fixed, and the scan is provided by the relative rotational and translational movement between the X-ray source and the object (the radiation source to the object irradiation). 由于锥束源相对于多个沿着扫描路径的源位置(即,「视角」)的移动,探测器会获得对应的多个锥束投影顺序数据集(本文中亦称之为锥束数据或投影数据),每一锥束数据集代表由物体在其中一个相应源位置处造成的X射线衰减。 Because of the cone-beam source with multiple source locations along the scan path (ie, "Perspective") movement, the detector will be a corresponding plurality of cone-beam projection data set sequence (herein also referred to as the cone-beam data or projection data), each set of cone beam data in which an object represented by a corresponding source positions caused by X-ray attenuation.

[0131] 图10显示例示性使用者介面,该使用者介面显示在另一实施例中可以牙根信息显示的萌生牙齿。 [0131] Figure 10 shows an exemplary user interface, the user interface is displayed in another embodiment, the information displayed may be root initiation teeth. 可使用适合的手柄对每一牙齿进行单独调节。 Can be individually adjusted for each tooth using a suitable handle. 在图10的实施例中,手柄允许操作者让牙齿在三个维度上以六个自由度进行移动。 In the embodiment of Figure 10, the handle allows an operator to make teeth in three dimensions with six degrees of freedom to move.

[0132] 部分地,使用基于牙根的排序系统对牙齿移动进行导向。 [0132] In part, the root-based ordering system for guiding tooth movement. 在一实施例中,移动是由表面积约束来约束,而在另一实施例中,移动是由体积约束来约束。 In one embodiment, the mobile is constrained by a surface area constraint, and in another embodiment, the movement is constrained by a volume constraint.

[0133] 在一实施例中,该系统确定每一牙齿模型的表面积。 [0133] In one embodiment, the system determines the surface area for each tooth model. 然后,该系统对待移动的全部牙齿模型的全部表面积进行求和。 Then, the total surface area of all of the system to treat the dental model mobile summing. 接下来,该系统对牙弓上的全部牙齿模型的全部表面积进行求和。 Next, the system of the total surface area of all the teeth on a dental arch model are summed. 对于牙齿移动的每一阶段,该系统会检查在移动牙齿模型时预定的面积比或约束得到满足。 For each stage of teeth movement, the system checks at the time of moving the tooth models predetermined area ratio or constraint is met. 在一实施方案中,该约束可为:移动牙齿的表面积要小于支撑移动中的牙齿的牙弓上的牙齿总表面积。 In one embodiment, the constraint may be: the surface area of the support to move the teeth to the teeth is less than the total surface area of movement of the teeth on the arch. 若该比例大于特定数值(如50% ),则该系统向操作者指示错误信号,以指示应较慢地移动该牙齿。 If the ratio is greater than a certain value (e.g. 50%), then the system indicates an error signal to the operator to indicate the tooth should move more slowly.

[0134] 在另一实施例中,该系统确定每一牙齿模型的体积。 [0134] In another embodiment, the system determines the volume of each tooth model. 然后,该系统对移动中的全部牙齿模型的体积进行求和。 Then, the entire volume of the system to move the teeth in the model are summed. 接下来,该系统确定牙弓上全部牙齿模型的总体积进行求和。 Next, the system determines the total volume of all tooth models on the arch summed. 对于牙齿移动的每一阶段,该系统会检查当牙齿模型移动时预定体积比或约束得到满足。 For each stage of tooth movement, the system checks if a predetermined volume ratio or constraint is met tooth movement model. 在一实施方案中,该约束可为:移动牙齿的体积要小于支撑移动中牙齿的牙弓上的全部牙齿的体积。 In one embodiment, the constraint may be: volume of the support to move the teeth to less than the volume of all the teeth in the tooth arch moving on. 若该比例大于特定数值(如50%),则该系统向操作者指示错误信号,以指示应较慢地移动该牙齿。 If the ratio is greater than a certain value (e.g. 50%), then the system indicates an error signal to the operator to indicate the tooth should move more slowly.

[0135] 可选地,可将其他特征添加至牙齿模型数据集以产生矫正器中的合意特征。 [0135] Optionally, you can add other features to the dental model data sets to produce a desirable characteristic in appliances. 例如, 合意的情形可能是添加数位蜡贴来定义腔室或凹陷,以保持矫正器与牙齿或颚的特定区域之间的空间。 For example, the situation may be desirable to add digital wax paste to define a chamber or recess, in order to maintain spatial aligner specific regions between the teeth or jaw. 合意的情形亦可是添加数位蜡贴来定义皱褶的或其他的结构形式,以建立具有特定硬度或其他结构特性的区域。 The case may also be desirable to add digital wax paste to define folds or other structural forms to create regions having particular stiffness or other structural properties. 在依赖于产生正模型以生产复位器具的制造过程中, 添加蜡贴至数位模型将制作具有相同添加蜡贴几何形状的正模。 In a positive model relies on the production of the manufacturing process to reset the appliance, add the paste wax to the digital model will be produced with the same geometry paste wax to add holotype. 这可通用于定义矫正器的基础形状或用于计算特定矫正器的形状。 This can be common to define the shape or aligner basis for calculating the specific aligner shape. 可添加的一个特征是牙龈线周围的镶边,可藉由在数位模型牙齿(矫正器根据该数位模型牙齿进行制造)的牙龈线处添加数位模型钢丝来制作该镶边。 A feature that can be added is trim around the gum line, and can be in digital dental models (braces were manufactured according to the digital model of the tooth) is added at the gum line to create digital models of the steel trim. 当藉由将聚合物材料压力配合于数位牙齿的正物理模型上来制造矫正器时, 沿着牙龈线的钢丝使得矫正器在其周围具有镶边,从而沿牙龈线提供额外的硬度。 When the positive physical model of the polymeric material by press fit onto the teeth in the digital appliance manufacturing, along the gum line wire such that appliance having a trim around it, thereby providing additional stiffness along the gumline.

[0136] 在另一可选制造技术中,将两片或更多片材料压力配合于正牙齿模型上,其中一片材料是沿矫正器的拱顶进行剪裁,且其余的材料覆盖于顶部。 [0136] In an alternative manufacturing technique, two or more sheets of material are pressure fit on the dental model, wherein the sheet of material along the trimming device dome correction, and the rest of the material covering the top. 这沿牙齿的垂直壁至少提供双倍厚度的矫正器材料。 This provides a double thickness of aligner material along the vertical walls of at least the teeth.

[0137] 可对矫正器设计作出的改变受到制作矫正器所使用的制造技术的约束。 [0137] to correct the design changes may be made subject to the constraint used in the production of appliance manufacturing technology. 例如,若藉由将聚合物片压力配合于正模型来制作矫正器,则矫正器的厚度由片厚度来确定。 For example, if the polymer sheet by press fit to the positive model to create the aligner, the thickness of the aligner is determined by the sheet thickness. 因此, 一般而言,该系统将藉由改变模型牙齿的取向、模型牙齿若干部分的尺寸、附件位置和选择、以及添加材料或去除材料(例如,添加钢丝或形成陷窝)以改变矫正器结构的方式来调节矫正器的性能。 Thus, in general, the system will by changing the orientation of the model teeth, the size of portions of the model tooth, attachment position and selection, as well as adding material or removing material (e.g., adding wires or formed dimples) to change the structure of the aligner The way to adjust the performance of the aligner. 可选地,该系统可藉由指定一个或多个矫正器由非标准厚度材料片制成以对牙齿提供更大或更小的力的方式来调节矫正器。 Alternatively, the system can be specified by one or more non-standard thickness of the aligner material sheet is made of the teeth to provide more or less force to adjust the way the aligner. 另一方面,若藉由快速成型工艺(例如,立体微影工艺或光微影工艺)来制作矫正器,则矫正器的厚度可局部地变化,且可添加如镶边、陷窝及褶皱等结构特征,而无需修改牙齿的数位模型。 On the other hand, if by rapid prototyping process (e.g., stereo lithography process or a photolithography process) to make the aligner, the thickness of the aligner can be varied locally, and may be added, such as chrome, and folds like the dimple structural features, without having to modify the digital model of the teeth.

[0138] 该系统亦可用以建立关于更多习用器具(如牙架和矫正器)效果的模型,且因此可用以产生用于特定患者的最佳设计及治疗方案。 [0138] The system can also be used to build on more conventional instruments (such as aircraft and dental braces) the effect of the model, and thus the best design and treatment options available to produce for a particular patient.

[0139] 图11A-11B分别图解带有定位牙具的初始牙齿位置,以及所获得的非合意力向量。 [0139] Figure 11A-11B, respectively, the initial diagram with positioning teeth with tooth position, as well as non-consensual force vector obtained. 参照图示,在其中牙齿显示为沿面方向(沿X方向)移动的实例中,在牙具(如,聚合物壳体矫正器)定位在牙齿上之后,矫正器的几何外形构造为对牙齿施加预定力,以根据特定治疗阶段的治疗计划对牙齿进行复位。 Reference to the drawings, in which the tooth is displayed as the plane direction (X direction) movement of example, after the dental equipment (e.g., polymeric shell aligner) positioned on the teeth, braces geometry configured to apply a predetermined tooth force, in accordance with a particular stage of the treatment plan for treating tooth reset. 例如,如图IlB所示,牙具构造为与牙齿啮合以如所示沿χ方向复位牙齿,然而如箭头所示和所图解,却导致沿+x/-z方向施加的预定力。 For example, as shown in Figure IlB, a tooth for tooth structure as shown engaged to reset the teeth along the χ direction, however, as shown by the arrows and diagrams, but lead to a predetermined force along the + x / -z direction applied.

[0140] 因此,在一个方面中,可优化矫正器几何外形以补偿非合意的但已形成的力向量以对该力形成反作用,并进一步沿基考量中的治疗阶段的治疗计划的方向施加既定的力。 [0140] Accordingly, in one aspect, the aligner geometry can be optimized to compensate for non-force vector desirable but has been formed to the formation of a reaction force, applied to the treatment plan established direction and further consideration of the direction of the base treatment stage force. 即,图11C-11D分别图解给牙具添加离隙以对牙齿周围的非合意力向量形成反作用、以及所获得的牙具对牙齿施加的合意预定力。 That is, each illustrated in Figure 11C-11D to add teeth with a relief to non-consensual force vector around the teeth to form a desired predetermined force is counterproductive, and a tooth for tooth obtained imposed. 在一方面中,为对非合意力(例如,如图IlB箭头所示)进行补偿,可提供预定的离隙(例如,但不限于,0. 1至0. 3mm)以避免于矫正器与牙齿之间造成非合意力向量的接触,但仍保留(例如)沿上述χ轴的合意力。 In one aspect, for the non-consensual force (e.g., as shown IlB arrows) to compensate, to provide a predetermined gap away from (e.g., but not limited to, 0.1 to 0. 3mm) in order to avoid in the aligner and resulting in non-consensual contact between the teeth of the force vector, but still retain (for example) along the χ axis consensual force.

[0141] 参照图11C,所示箭头是图解矫正器上的预定离隙,由此藉由修改矫正器的几何形状而去除了矫正器与牙齿之间造成非合意力位置处的啮合。 [0141] Referring to FIG. 11C, arrows are pre-correction on the diagram from the gap, thus corrected by modifying the geometry of the appliance away except between the teeth caused by the engagement of non-consensual force at the position. 以此方式,在一方面中,且如图IlD所示,藉由(例如)修改矫正器的几何外形而实现了沿χ方向施加于牙齿的既定且合意的力。 In this manner, in one aspect, and as shown in FIG. IlD, by (e.g.) to modify the aligner geometry is achieved along the χ predetermined direction is applied to the teeth and a desired force.

[0142] 图12图解修改的牙具几何外形,其中包括用以去除牙具与牙齿之间间隙的附加形状修改。 [0142] Figure 12 illustrates a modified tooth geometry, including the removal of additional shape to modify the gap between the teeth with the teeth. 参照图12,请注意,尽管对矫正器几何外形的修改(如上文结合图11C-11D所论述)会导致由牙科治疗所计划的合意预定力施加于牙齿,但例如,如图12中所示,牙齿与矫正器之间、于牙龈区域附近可能会形成间隙或腔。 Referring to Figure 12, note that, although the aligner geometry modification (above in connection with FIG. 11C-11D discussed) will cause a desired predetermined force by a dental treatment plan is applied to the teeth, but for example, shown in Figure 12 between the teeth and braces, in the area near the gums may be a gap or cavity. 在一方面中,鉴于所产生之间隙或腔,可对矫正器几何外形进一步修改或优化,以(例如)当矫正器处于有效(拉伸)状态时在朝向牙齿的方向上具有更加的适应性。 In one aspect, in view of a gap or cavity arising, the aligner geometry may be further modified or optimized to a direction (e.g.) When the aligner is in its active (stretched) state when the facing teeth having more adaptability .

[0143] 参照图12,在一实施例中,箭头(箭头的方向是可对矫正器形状进行修改的方向) 是图解优化矫正器几何外形,以解决所形成之间隙或腔。 [0143] Referring to FIG 12, in one embodiment, the arrow (direction of the arrow is the direction of the aligner shape can be modified) is a diagram aligner geometry optimized to address the gap or cavity formed. 此外,应注意,针对间隙而进行的矫正器形状优化可能潜在地影响矫正器对牙齿施加力的方向,且因此可能需要进一步进行附加的修改或优化。 Further, it should be noted that the shape of the aligner carried optimized for gap may potentially affect the aligner direction of the force exerted on the teeth, and therefore may require additional modifications or further optimization.

[0144] 在一方面中,以一个或多个离隙区域来修改牙科矫正器外形,且分别为较松适应或较紧适应进行轮廓修整以实现合意力向量,而同时避免摩擦和其他非合意力向量,由此为所述牙科条件的治疗提供改进和自订的矫正器形状。 [0144] In one aspect, one or more of the relief area to modify the shape of dental appliances, and are each adapted for loose or tight adapt the contour trimmed in order to achieve a desired force vector, while avoiding friction and other non-consensual force vector, which is the treatment of the dental condition and provides improved correction custom shape.

[0145] 在牙具制造中,在一方面中,可在建立过程期间调节快速成型所形成的模子,以呈现基于(例如)在模子的预定义位置或相关位置中数位添加及/或减去离隙及/或突出部分的合意几何形状。 [0145] In the manufacture of dental equipment, in one aspect, can be adjusted during the process of establishing a mold formed by rapid prototyping, to render based (e.g.) in a predefined position within a mold or a related position and the number of bits are added / subtracted from or Gap and / or desirable geometry of projections.

[0146] 图13图解基于牙齿治疗计划的扫描几何形状来构造牙具几何外形。 [0146] Figure 13 illustrates the geometry of the scan-based dental treatment plan to construct a tooth geometry. 参照图13,在一方面中,由于牙科矫正器与牙齿之间的摩擦可对治疗形成限制,因而在一方面中,可藉由去除当前位置(当前治疗阶段)与下一位置(n+1治疗阶段)之间的所有干扰来优化矫正器的几何形状。 Referring to Figure 13, in one aspect, since the friction with the orthodontic treatment of teeth may be formed between the restrictions, which in one aspect, can be removed by the current position (current treatment period) and the next position (n + 1 All interference treatment phase) between the optimized geometry of the aligner. 即,可产生当前位置与下一位置之间的扫描几何形状。 That is, can produce scan geometry position between the current and the next position. 图13中所示的扫描几何形状是当前位置与朝向下一位置(n+1治疗阶段)的下一无限小增量之间的联合几何形状。 Scan geometry as shown in FIG. 13 is combined with the geometry of the current position toward the next position (n + 1 treatment stage) next between infinitely small increments. 藉由累加该等无限小增量,所获得的几何形状便确立了扫描几何外形。 By accumulating these infinitely small increments, then the geometric shape of the obtained scanning geometry established.

[0147] 再次参照图13,在确定矫正器扫描几何形状以最小化或去除牙齿与牙科矫正器之间的摩擦之后,可给矫正器形状添加一个或多个变形或离隙,以提供合意的移动向量,以沿针对治疗计划的特定治疗阶段所确定的方向施加既定的力。 [0147] Referring again to FIG. 13, after determining that the scanning aligner geometry to minimize or eliminate friction between the tooth and the dental appliance can be shaped to the aligner deformation or adding one or more reliefs, to provide desirable motion vector, along a specific treatment plan for the treatment phase as determined by the direction of the applied predetermined force.

[0148] 在另一方面中,可探测何时因所产生的力不充分而无法导致牙齿的移动。 [0148] In another aspect, can detect when force generated due to insufficient and can not cause movement of the teeth. S卩,垂直于合意移动线(或垂直于移动向量的方向)的表面积量可能不足以让矫正器达成必需的力。 S Jie, moving perpendicular to the desirable line (or perpendicular to the direction of the motion vector) of the amount of surface area may be insufficient so that the force necessary to achieve the aligner. 例如,在突出方向上(如图12中所示,沿+Z轴),所存在的根切力可能不足以能沿该方向推动牙齿。 For example, in the projecting direction (shown in Figure 12, along the + Z axis), the existence of the undercut can promote tooth force may not be sufficient in this direction. 因此,可在牙齿上添加或提供牙科附件,以改善垂直于牙齿移动的合意方向的表面积量。 Therefore, you can add or dental attachment to the teeth, in order to improve the amount of surface area perpendicular to the desirable direction of tooth movement.

[0149] 在一方面中,基于由材料性质以及垂直于复合向量(其由特定治疗阶段的移动向量造成)的表面积量所确定的力行为,可藉由采用特别适合于合意移动的牙科附件,给牙齿增加额外的表面积。 [0149] In one aspect, based on the behavior of the material properties and the force perpendicular to the composite vector (which is caused by a particular treatment stage motion vector) of the surface area of the determined amount may be desirable particularly suitable for mobile use dental attachments, additional surface area to tooth. 以此方式,在一方面中,可确定某一特定牙齿的表面积的剖面,且牙科附件可定位在牙齿上,以增大或改善必要的表面积以与牙具相协作或啮合,以实现沿治疗阶段的准确方向的作用于牙齿的合意移动向量或预定水平的力。 In this manner, in one aspect, may determine a specific surface area of the cross section of the teeth, and dental attachments may be positioned on the tooth, to increase or improve the surface area necessary to cooperate with the teeth with or engaged to achieve along the treatment period The exact role of the direction of movement of the tooth of a desired or predetermined level of force vector.

[0150] 以此方式,在一方面中,可使用电脑辅助设计工具或系统来制造或仿真牙科矫正器,其中首先建立关于待移动牙齿图像的模型。 [0150] In this way, on the one hand, you can use the computer-aided design tools or systems to manufacture dental braces or emulator, which first established the image of the tooth to be moved on the model. 此后,藉由所定义的几何外形性质来建立关于定义牙齿目标位置的矫正器。 Thereafter, the geometric shape defined by the nature of the teeth to establish a definition of the target position aligner. 此后,例如,使用FEA建模或其他适合的计算及/或建模技术来确定或建立关于使牙齿自初始位置复位至目标位置所必需的力的模型。 Thereafter, for example, the use of FEA modeling, or other suitable computing and / or modeling technique to determine or establish on the teeth from the initial position so that the target position is reset to the force necessary to model. 在一方面中, 可使用连接至力量测感测器的牙齿的物理模型来定义该力,以便可使用自物理模型获得的读数来确定最佳力,因此,至少部分地基于来自物理力仪表的反馈来更改附件和矫正器构形的形状。 In one aspect, the physical model may be used to connect to the power of the measured sensor teeth to define the force to be used to obtain the readings since the physical model to determine the optimum force, and therefore, at least in part from the physical forces on the instrument Feedback to change accessories and appliance configuration shape.

[0151] 因此,确立所施加力方向的移动向量、以及对于自初始位置复位至目标位置必要的力水平和其性质得到定义。 [0151] Accordingly, the motion vector to establish the direction of the applied force, and for resetting to the initial position since the target position of the force necessary to obtain the level and nature of their definition. 基于移动向量及建模的矫正器形状,对矫正器进一步修改或重新构形以将所确定的移动向量纳入考量。 Based on the motion vector and the aligner shape modeling, to further modify or braces reconfigured to the determined motion vectors into account. 即,在定义移动向量(该向量识别对于牙齿复位必要的力性质)之后,基于所确定的移动向量来更改或优化牙具形状。 That is, in the definition of the motion vector (the vector for identifying the nature of the force necessary to reset the teeth), the motion vector based on the determined change or optimize dental appliances shape. 另外,可进一步优化器具形状以对基于定义的移动向量而可能导致的非合意力或分力进行反作用。 In addition, in order to further optimize the shape of the appliance or component of a non-consensual force vector is defined based on the mobile which might lead to be counterproductive.

[0152] 此后,可经由快速成型或其他适合的技术来制造经修改的或优化的牙具,以达成合意的牙齿移动。 [0152] Thereafter, via rapid prototyping or other suitable techniques to produce modified or optimized with the teeth, to achieve a desired tooth movement. 此外,可重复该过程以针对治疗计划的每一治疗阶段优化牙具,以使矫正器性能以及治疗计划结果得到改善。 Further, the process is repeated with each stage of treatment for the treatment plan optimization teeth, so that corrective treatment plan and the results of performance improvement.

[0153] 另外,在一方面中,提供交互作用的分析过程,其中将轻微或微小局部改变引入矫正器几何外形中,且其中所获得力分布的效果在(例如)治疗计划的每一治疗阶段中与合意力相比较,且若该结果接近目标分布则重复该过程,且若结果离开或偏离目标分布则忽略该过程。 [0153] Further, in one aspect, there is provided interaction analysis, wherein the minor or small local changes in the geometry of the introduction of the aligner, and wherein the effect of the force distribution in each of the treatment period (e.g.) the treatment plan compared with a desired force, and if the result is close to the target distribution the process is repeated, and if the results deviate from the target to leave or ignore the distribution process. 针对治疗计划的每一治疗阶段重复该过程,以使该系列牙具或矫正器的相应几何外形各自得到优化,以改善治疗结果。 Each treatment stage of the treatment plan for the process is repeated, so that the corresponding geometrical shape of the series of dental appliances or braces each optimized to improve treatment outcomes.

[0154] 在另一方面中,在一实施例中,牙具构形可基于上文论述的扫描几何形状,以最小化牙具与相应牙齿之间的摩擦,此外,可修改牙具以建立一个或多个个别的接触点或表面(例如,使用接合至牙齿的附件的陷窝或接触),以产生合意的力。 [0154] In another aspect, in one embodiment, a tooth configuration can be based on the scan geometry discussed above, in order to minimize friction between the teeth with the corresponding teeth with, in addition, can be modified in order to establish one or more teeth with an individual contact points or surfaces (e.g., using the bonding to the tooth attachment dimples or contact), to produce a desired force. 可使用(例如)电脑辅助设计或建模工具来建立关于所获得的牙具几何形状(包括当前和后续(n+1阶段)的扫描路径几何形状)以及力产生移动(如上文所述的移动向量)的模型。 You can use (for example) computer-aided design or modeling tools to build on tooth obtained with geometries (including the current and subsequent (n + 1 stage) scan path geometry) and force generation mobile (as described above motion vectors ) model.

[0155] 此外,在再一方面中,可基于垂直于牙齿移动的合意方向的最大量可用表面积的位置来确定牙科附件的布局。 [0155] Further, in another aspect, may be based on the location of the maximum amount of available surface area perpendicular to the direction of tooth movement is desirable to determine the layout of the dental attachment. 此外,若在治疗计划中作用于任何给定牙齿的力处于或低于预定义水平,则可将附件添加至牙齿以增补合意的表面积或增大牙齿的摩擦系数,由此改善矫正器在牙齿上的力分布。 Moreover, if applied to any given dental treatment plan in force at or below a predefined level, may be added to supplement the attachment to the teeth or desirable to increase the surface area of the teeth of the friction coefficient, thereby improving the tooth aligner force distribution on.

[0156] 在一方面中,可经由(例如)加法、局部或总体减法、均勻或非均勻比例缩放、布林或非布林演算法或几何作业或其一个或多个组合有意地更改与牙齿、牙龈及/或其他口腔组织或结构相关联的数据集,以便可针对合意或既定的治疗目标优化牙具的构形、建模及/ 或制造。 [0156] In one aspect, the via (e.g.) addition, partial or total subtraction, uniform or non-uniform scaling, Brin Brin algorithm or non-geometric operations or one or more intentional changes in combination with the tooth , gum and / or other oral tissues or structures associated data sets to be desirable or intended for the treatment of teeth with the goal of optimizing the configuration, modeling, and / or manufacturing.

[0157] 此外,参照上文关于附件的论述,可提供附件的成角或附连以及表面构形,以改善移动向量,以优化移动向量对于合意牙齿的施加,而同时最小化可反作用于移动向量的非合意或有害力向量的量。 [0157] In addition, referring to the above discussion of attachment, the attachment can be provided or attached and angled surface configuration, to improve the motion vector, in order to optimize the motion vector is applied to a desired tooth, while minimizing movement can counteract the amount of non-consensual or harmful force vector of the vector. 另外,在一方面中,可提供一系列毗连附件以更改力方向或产生输送达某一预定时期的移动向量,以使该系列毗连附件可构造为起到慢动作凸轮的功能,而牙具则起到从动轮的功能。 Further, in one aspect, provides a range adjacent to the attachment to produce or change the direction of the force delivery of a predetermined period of the motion vector, so that the series of abutting attachments may be configured to function as slow-motion cam function, and teeth with the starting to the driven wheel function.

[0158] 在再一方面中,可添加点追踪以处理及/或追寻治疗阶段的牙齿点,以便可确定合意或适当的凸轮/从动轮关系,以达成目标位置或治疗目标。 [0158] In a further aspect, the tracking point may be added to treatment and / or treatment of dental point search stage, in order to determine desirable or appropriate cam / follower relationship, in order to achieve the target position or therapeutic target. 在一方面中,牙具内表面上的一个或多个突出部分可构造为从动轮,且可由虚拟压力点形成。 In one aspect, the inner tooth with one or more protrusions on the surface can be configured as a driven wheel, and by the formation of a virtual pressure points. 有意地建立或设计在参考模子或模型中的空隙的一个实施例中包括虚拟压力点,当矫正器形成于参考模子上时, 参考模子或模型与矫正器中既定于对牙齿施加额外压力的对应部分相关联。 Corresponds to an embodiment of the establishment or intentionally designed mold or model in the reference voids embodiment includes a virtual pressure points, when the appliance is formed on the reference mold, a mold or a reference model and aligners intended to exert additional pressure on the teeth Part associated.

[0159] 图14A-14B图解用于使牙齿转动的牙科附件定位。 [0159] Figure 14A-14B diagram is used to locate a dental accessory tooth rotation. 参照图14A-14B,如图所示,一对附件定位于牙齿的颊面表面和舌面表面上,其中心相对于牙齿定位在垂直于Z轴的平面中。 Referring to FIG. 14A-14B, as shown, a pair of attachment is positioned on the buccal and lingual surfaces of the tooth surface, the tooth with respect to the center thereof positioned in a plane perpendicular to the Z axis. 参照该等图示,该两个附件以图示中的相应箭头所示的相反方向在上述的平面中移位或偏置,以产生对应于净力为0的转矩的力偶,从而造成牙齿的转动移动。 Referring to such diagram, the attachment to the opposite direction of the two arrows shown in the corresponding shift or bias in said plane to produce a net force corresponding to the torque 0 of the couple, causing teeth The rotational movement.

[0160] 图15图解用于使牙齿倾斜的牙科附件定位。 [0160] Figure 15 illustrates the positioning of teeth used to make dental attachment tilt. 参照图15,可将一个附件定位于颊面表面上,而将另一附件定位于舌面表面上,该等附件的相对高度存在差异,且其中心或轴相对于牙齿定位于垂直于Y轴的平面内。 Referring to FIG. 15, an attachment may be positioned on buccal surface, and the other attachment positioned on the lingual surface, the relative differences in height of such accessories, and its center or axis relative to the teeth positioned perpendicular to the Y axis in the plane. 力沿箭头所示的方向施加于附件,从而造成相对于牙齿位置沿Y轴的转矩,且所获得的净力为0。 Direction of the force applied to the arrow shown in the annex, resulting in torque with respect to tooth positions along the Y-axis, and the obtained net force is zero. 在另一方面中,附件可定位相对于牙齿垂直于Y轴的平面中。 In another aspect, the attachment member may be positioned with respect to the teeth perpendicular to the Y axis of the plane. 以此方式,施加于附件以使一个附件朝牙合面平移的力以及同一平面内沿相反方向的另一力会导致牙齿的倾斜。 In this manner, is applied to the attachment to make an attachment surface toward the occlusal force translational force and another in the same plane in the opposite direction will cause the inclined teeth. 该方法可使用于(例如)正畸术的牙根扭转(舌面牙根倾斜)中,而牙齿的转动中心位于牙冠中,因此牙根将会发生倾倒或倾斜。 This method can be used (e.g.) to reverse the orthodontic surgery root (root lingual inclination), whereas the teeth of the crown located in the center of rotation, so inclined root pouring or will occur.

[0161] 图16图解用于使牙齿成角的牙科附件定位。 [0161] Figure 16 illustrates the positioning of teeth used to make dental accessory angled. 如所示,该对附件定位于牙齿上,而相应的力如相应箭头所示施加于牙齿上。 As shown, the pair of attachment is positioned on the tooth, while the corresponding force as shown by an arrow is applied to the corresponding tooth. 该效果会造成牙齿的成角(例如,沿图16中所示实施例中的顺时针方向)。 This effect will cause the teeth angled (e.g., 16 shown in FIG along embodiment clockwise direction).

[0162] 图17A-17B图解分别用于颊面平移和舌面平移的牙科附件定位。 [0162] Figure 17A-17B diagrams are used to translate buccal and lingual translation dental attachment positioning. 参照该等图示, Reference to those shown,

24如图所示的该对附件可在相对于牙齿的XY平面中定位于颊侧和舌侧上。 As shown in Figure 24 the pair of attachments can be positioned on the buccal side and the lingual side of the tooth with respect to the XY plane. 由于两个附件定位在相对于牙齿转动中心的不同高度处,因此靠近转动中心定位的附件被推入牙冠的程度大于相对于远离转动中心的附件。 Since the two attachments positioned at the center of rotation with respect to the teeth of different heights, and therefore the degree of rotation near the center of the positioning of the attachment is pushed into the crown away from the center of rotation is greater than with respect to the attachment. 因此,作用于牙齿的总力将是正值,但可将倾倒转矩调为0,因为可将来自两个附件中每一附件的作用于转动中心的力杠杆分量调节为相等、方向相反。 Therefore, the total force acting on the teeth will be positive, but it can be adjusted to zero torque dumping, since it could be from the role of each of the two accessory attachment lever in the center of rotation of the force component is adjusted to equal and opposite. 该方法可实现牙根平移。 This method can achieve root pan.

[0163] 图18A-18B分别图解用于近中平移和远中平移的牙科附件定位。 [0163] Figure 18A-18B, respectively, near the pan and illustrations for dental attachment positioning the distal translation. 参照该等图示, 藉由如图所示地定位该对附件并对其施加适合的预定力,可获得牙齿的近中平移和远中平移。 Reference to those shown, as shown by the positioning of the Annex and shown to exert a predetermined force fit, get teeth mesial and distal translation translation.

[0164] 图19A-19B分别图解用于突出和下压的牙科附件定位。 [0164] Figure 19A-19B, respectively diagrams used to highlight and dental accessory position under pressure. 参照该等图示,该情形下的该对附件与包含Z轴的平面中心一同定位于牙齿的舌侧和颊侧。 Reference to those shown, the Annex and the plane containing the central axis of the Z-case with localized in lingual and buccal teeth. 图中所示的两个附件构造为沿Z轴向上移动以实现突出,或沿Z轴向下移动以实现下压。 Two attachment configuration as shown along the Z-axis movement in order to achieve projection or lower along the Z axis to effect movement under pressure. 产生于该两个附件或施加于该两个附件的力在量值上不同(例如,此乃因相对于牙冠的不同局部附件移动而造成)。 Produced in the two annexes or apply force to the two annexes different in magnitude (for example, which was due to different local attachment relative movement caused by the crown). 当来自附件的力对转动中心造成大小相等、反向相反的力臂时,倾倒转矩可被抵消,且所获得的力可包括牙齿的突出或下压平移。 When the force from the center of rotation caused by the attachment of the same size, and opposite the arm, the torque can be offset by pouring, and the obtained force can comprise teeth protruding or depressed pan.

[0165] 此外,导致上述突出或下压的附件移动可与作用于牙冠上的平移移动一同使用以获得反向平衡转矩。 [0165] In addition, the movement of the prominent cause attachment or under pressure acting on the translational movement with the crown on the balance used together to obtain a reverse torque. 例如,藉由将附件构造为相对于牙冠使其朝向颊面表面上的咬合平面移动,可反向地平衡由颊面移动造成的倾倒转矩。 For example, with respect to the attachment structure for the crown snap it on the plane to move toward buccal surface, can reverse the torque balance dumping caused by the buccal movement.

[0166] 另外,造成突出或下压平移的附件移动可与局部膨胀的矫正器一同使用,局部膨胀的矫正器包括于一些牙冠上鼓起的矫正器表面,以使矫正器表面不与处于被动状态的牙冠相接触。 [0166] In addition, the pressure caused by translational movement projecting attachment or lower can be used with the appliance partially expanded, partially expanded in a number of appliances including the crown swollen aligner surface, so that the appliance and the surface is not crown passive state in contact. 当膨胀矫正器与附件移动一同使用于转动时,可获得最大的转动转矩和最小的有害力,此乃因矫正器仅对附件进行干扰,以产生(例如)总力为0的转动力偶。 When the expansion of mobile appliances and accessories used in conjunction with the rotation, rotational torque for maximum and minimum harmful force, which was due to interference accessory appliance only to produce (for example) the total force to rotate couple 0 .

[0167] 在再一实施例中,可使用预先制作的附件来减少或消除因不适当附件成形而引起的失效。 [0167] In a further embodiment, the pre-made accessories can be used to reduce or eliminate failures due to improper attachment forming caused.

[0168] 因此,在一方面中,首先确定n+1或后续/目标牙齿位置。 [0168] Accordingly, in one aspect, the first or a subsequent n + 1 is determined / target tooth positions. 此后,确定自初始牙齿位置到达目标牙齿位置的移动方向。 Thereafter, to determine the initial tooth position has been reached since the moving direction of the target tooth position. 在确定移动方向之后,确定用以使牙齿自初始位置复位至目标位置的力以及转矩的量或量值及方向。 After determining the moving direction, and determining the amount or direction for moving teeth from an initial position to a target position resetting force and torque. 此后,确定沿所计划的牙齿移动的方向提供最适合固持的附件的轮廓(如,几何形状),并且确定附件相对于牙齿表面的最佳位置。 Since then, determine the direction along the planned tooth movement to provide the most suitable contour retaining attachments (eg, geometry), and to determine the best location relative to the surface of the tooth attachment.

[0169] 确定附件相关轮廓之后,确定达成自初始位置至目标位置的附件移位。 [0169] After determining the relevant annex outlines, to determine the initial position to reach the target location since attachment shift. 在将附件定位于牙齿上之后,后续治疗阶段的牙具经由定位的附件与牙具相啮合并接触。 After the attachment is positioned on the teeth, teeth with subsequent treatment stages and meshed contact via positioning accessories and dental equipment.

[0170] 以此方式,牙具所产生的力/转矩沿合意的方向准确定向,且亦配置为具有足以使牙齿移动进入下一计划位置的量值。 Force [0170] In this way, dental equipment produced / torque along a desired direction accurate orientation 且亦 configured with enough teeth to move into the next program position value. 例如,在一实施例中,将附件接合至患者牙齿。 For example, in one embodiment, the attachment to the patient engaging teeth. 如上文所述,确定附件的初始位置。 As described above, to determine the initial position of the attachment. 移位或复位的附件可产生与牙具上的附件形状相一致的腔室新位置。 Shift or reset attachments and accessories can be generated on the shape of a tooth cavity consistent with the new location. 由于附件在初始阶段位于牙冠上且在后续目标治疗阶段发生移位,因此目标治疗阶段的牙具可干扰初始治疗阶段牙齿上的附件。 Since in the initial stage of attachment located on the crown and the shift occurs in the subsequent stages of treatment targets, and therefore the treatment of teeth with the target initial attachment phase may interfere with treatment phase teeth. 该干扰本身亦配置为产生形成合意牙齿路径的力/转矩。 This interference is also configured to force itself desirable path to produce tooth formation / torque.

[0171] 在一方面中,可修改或优化力/转矩的方向和量值,以产生反向平衡力/转矩,以藉由调节(例如)相对于牙冠表面的附件移位量来消除或最小化有害倾倒转矩,以达成牙根移动或类似的移动。 [0171] In an aspect, may modify or optimize force / torque direction and magnitude, to produce reverse counterbalancing force / torque to be adjusted (for example) with respect to the attachment surface of the crown to the shift amount eliminate or minimize deleterious dumped torque, movement, or the like in order to achieve root movement. 相对于牙冠的附件移动量亦可与牙齿移动相关联,以基于附件的移动产生治疗计划。 Relative to the amount of movement of the crown attachment can also be associated with tooth movement to move attachments generated based treatment plan. [0172] 图20图解牙具及附件的互补啮合。 [0172] 20 illustrates a tooth meshing and complementary accessories. 参照图20,在一方面中,牙具(如图20中标记为(a)的牙具)上提供有突出部分或按钮,在一实施例中,该突出部分或按钮构造为与附件(图20中标记为(b)的附件)上的对应凹槽或陷窝相啮合,且定位于牙齿表面上。 Referring to Figure 20, in one aspect, toothbrush (labeled in FIG. 20 (a) of the dental equipment) provided with a projecting portion or on the button, in one embodiment, the protruding portion or the button configured with accessories (Fig. 20 corresponding grooves or dimples labeled (b) of the attachment) that engage, and positioned on the tooth surface. 以此方式,藉由牙具上的按钮或突出部分以及附件上用以接纳突出部分的腔室,可构造突出部分的相对位置以对附件器件施加点力或面区域力。 In this way the relative position, with buttons on a tooth or protruding part and the chamber for receiving the protruding part of the attachment, you can highlight the part of the structure to the point of attachment devices applied force or stress surface area.

[0173] 因此,可对牙具或矫正器上的突出部分以及接纳附件器件上的腔室进行构造,以形成可在该处施加点力的结合或啮合。 [0173] Thus, the chamber protrusions or teeth with braces on and accept attachments on the device constructed to form a binding or engagement can be applied at the point where the force. 此外,在(例如,基于上述的一个或多个移动平移) 对牙具上突出部分的相对位置以及附件上的腔室进行局部修改的情形下,可将点力或面区域力定向成导致对应的牙齿移动。 In addition, in (e.g., based on one or more of the above described mobile translation), and the relative position of the projection on the attachment portion of the chamber of teeth with partial modification on the case, may be a point force or force surface area oriented to result in a corresponding tooth movement.

[0174] 此外,在本发明一个方面中,构造成提供面向牙齿的更改点力的表面区域可包括朝向牙齿内部的脊状部分突出部分或扁平突出部分。 [0174] Further, in one aspect of the present invention, configured to provide a force to change the point of the surface area facing the tooth-like portion may include a ridge protruding toward the inside of the part of the tooth or flat projection. 另外,该力在n+1阶段亦可包括「加强」表面区域,其中在一方面中,可藉由一个或多个脊状部分或折痕来构建皱褶,以使面向牙齿的内表面与牙齿保持全接触(而非点接触或脊状部分的接触)且使得该内表面在局部支撑区域中得到加强,以使力不如在未得到支撑的区域中一样容易分散。 In addition, the force of the n + 1 stage may also include "strengthening" surface area, which in one aspect, can be one or more ridges on the folds or creases to build, so that the inner surface facing the teeth and Keys dental retainer (rather than point contact or contact ridge portions) and such that the inner surface of the support to be strengthened in the local area, so that the force is not as easy as in the support area has not been dispersed.

[0176] 再次参照图21,在确定与自初始位置至目标位置的牙齿移动相关联的移动向量之后,在步骤2140处,确定与移动向量相关联的分量。 [0176] Referring again to FIG. 21, in determining a motion vector associated with the tooth movement since the initial position to a target position, in step 2140, to determine the component of the motion vector associated. 例如,如上所述,确定与使牙齿自初始位置复位至目标位置的移动向量相关联的力量值。 For example, as described above, to determine the power value makes the teeth from the initial position to a target position is reset associated with the motion vector. 另外,确定牙齿移动的力方向以及解决有害或非既定力的反向力。 In addition, to determine the direction of the force and tooth movement opposing force to resolve harmful or established power. 此后,基于与移动向量(其与自初始位置至目标位置的牙齿移动相关联)相关联的确定分量,对牙具的腔室几何形状进行修改。 Thereafter, based on the motion vector (which is the initial position to the target position since the associated tooth movement) determining component associated teeth with the chamber geometry modifications.

[0177] 图22是图解牙科附件定位的流程图。 [0177] FIG. 22 is a flowchart illustrating the positioning of dental accessories. 参照图22,在步骤2210处,确定第一治疗阶段处的牙齿位置。 Referring to Figure 22, at step 2210, to determine the position of the teeth at the first stage of treatment. 在步骤2220处,确定第二治疗阶段或n+1治疗阶段的牙齿位置。 At step 2220, determining a second treatment phase or position of the teeth n + 1 treatment stage. 此后, 在步骤2230处,确定与自第一治疗阶段至第二治疗阶段的牙齿移动相关联的移动向量。 Thereafter, in step 2230, it is determined from the first associated with the treatment stage to the second stage of the treatment of tooth movement motion vector. 在确定与牙齿移动相关联的移动向量之后,在步骤2240处,确定与移动向量相关联的一个或多个牙科附件轮廓。 In determining the movement of the tooth associated with the motion vector, in step 2240, determining one or more dental attachments contour associated with the motion vector. 即,确定(例如)牙科附件的位置、牙科附件的成角、垂直于来自牙具力方向的表面积。 That is, it is determined (for example) the position of the dental attachment, angled dental attachments, perpendicular to the direction of the force from a tooth surface area. 此后,在步骤2250处,在第一治疗阶段期间,将一个或多个牙科附件定位在对应的牙齿上。 Thereafter, in step 2250, during the first phase of treatment, one or more dental attachments positioned on the corresponding tooth.

[0178] 以此方式,在一实施例中,来自牙具的力/转矩准确地施加至牙齿,以使牙齿自初始位置复位至目标位置或第二治疗阶段位置。 [0178] In this manner, in one embodiment, the force from the dental equipment / torque accurately applied to the teeth so that the teeth from the initial position to the target position, or resetting the second treatment stage position.

[0179] 参照图23,在步骤2310处,对于步骤序列中使牙齿自初始位置移动至目标最终位置的阶段,计算每一牙齿表面上每一点的轨迹以实现给定的预定阶段移动。 [0179] Referring to Figure 23, at step 2310, the sequence of steps for the manipulation teeth from the initial position to the final stage of the target position, calculate the trajectory of each point on each tooth surface in order to achieve a given predetermined stage movement. 根据轨迹,确定牙齿的有效表面2320。 According to the track, determining an effective surface of the tooth 2320. 有效表面是计算为满足如下条件的牙齿表面上所有的点ρ :牙齿表面的法相力N(p)在点ρ处到对应于合意移动轨迹Γρ的切向向量上的投影大于预定义正阈值。 Effective surface is computationally to satisfy the following conditions tooth surface all points ρ: tooth surface wears force N (p) at the point ρ place to correspond to a desired movement trajectory Γρ tangential projection vector is greater than the predefined positive threshold. 一旦有效表面经确定,针对患者的每一牙齿计算有效表面与牙根阻力表面之间的比例2330。 Once the effective surface has been determined for the calculation of the proportion of patients in each tooth surface and the effective resistance between the surface of the root 2330. 若该比例大于预定阈值,则牙齿具有所需牙齿移动的充分有效牙齿表面2340。 If the ratio is greater than a predetermined threshold, the teeth having a desired tooth movement fully effective tooth surface 2340.

[0180] 仍参照图23,若有效表面与牙根阻力表面之间的比例不大于预定义阈值,则可对现有牙齿表面进行最小改动2350。 [0180] Still referring to Figure 23, if the ratio of the effective surface resistance between the surface of the root is not greater than the predefined threshold value can be the smallest of the existing tooth surface modification 2350. 除其他以外,对现有牙齿表面的改动可包括自订的附件或器具,用以增大牙齿有效表面数量或将材料添加至牙齿表面。 Among other things, changes to the existing tooth surface may include custom accessories or equipment to effectively increase the number of tooth surfaces or add material to the tooth surface. 对现有牙齿表面的最小改动应满足如下约束:经修改的表面为所需移动提供有效表面,而该比例大于有效表面与阻力表面之间的阈值;经修改的表面是对当前位置的牙齿可触及表面的改动;以及经修改的表面必须满足制造要求。 Minimum changes to the existing tooth surface should meet the following constraints: the surface-modified to provide the desired effective surface of the mobile, and the ratio is larger than the threshold value and the effective surface resistance between the surfaces; modified surface is available for the current location of the teeth changes touch surface; and the surface must be modified to meet manufacturing requirements. 一旦现有牙齿表面经修改,则重复针对修改后牙齿表面的步骤2310-2330,由此透过对应的矫正器对新表面进行核查,以确保与修改后的牙齿表面存在足够的接触面积。 Once the existing tooth surface modified, the modified repeat steps 2310-2330 for the tooth surface, whereby through the corresponding surface of the aligner to a new verification, to ensure the presence of the modified tooth surface sufficient contact area.

[0181] 图24是图解确定附件对于获得充分牙齿有效表面积是否合意的方法的流程图。 [0181] FIG. 24 is a diagram for determining accessory obtain sufficient effective surface area of the teeth is desirable is a flowchart of a method. 参照图24,在步骤2410处,针对治疗计划的阶段序列中使牙齿自初始位置移动至目标位置的给定治疗阶段,可确定牙齿的刚体变换A。 Referring to Figure 24, at step 2410, the sequence for the treatment planning stage of manipulation teeth from an initial position to a target position given treatment phase, teeth may be determined rigid transform A. 在一方面中,刚体变换A可包括使牙齿自阶段η的位置移动至阶段η+1的位置的刚体变换。 In one aspect, the rigid body transformation A can include teeth from stage to stage of moving the position of η η + 1 position of rigid body transformation.

[0182] 参照图24,根据刚体变换Α,确定刚体变换空间内的测地曲线A (t),该刚体变换与对应于0移动I的刚体变换以及刚体变换A的刚体变换有关(2420)。 [0182] Referring to FIG. 24, according to the rigid transformation Α, determine the geodesic curve A (t) rigid transformation space, the rigid body transformation and movement corresponding to 0 and I are rigid transformation A rigid transformation of rigid transformation related (2420). 例如,在一方面中,对应于0移动I的刚体变换与保持相同、没发生任何移动或移位的所有点相关。 For example, in one aspect, the Mobile I 0 corresponding to rigid body transformation and remains the same for all points without any movement or displacement of the associated. 对于牙齿表面上的每一顶点V,计算曲线A(t)V在t = 0处的单元切向向量与牙齿表面在V处的内法向单元向量N的点积s (V) 2430。 For each vertex V on the surface of the teeth, the calculated curve A (t) V 0 at t = tangential unit vector in the method of the tooth surface at the unit V dot product of the vector N s (V) 2430.

[0183] 此后,确定牙齿的有效表面,牙齿的有效表面是具有至少一个顶点V且其中S(V) 大于预定义SC的所有牙冠表面的集合(2440)。 [0183] Thereafter, to determine an effective surface of a tooth, having an effective surface of a tooth, and wherein at least one vertex V S (V) is greater than the set of all surfaces of the crown of predefined SC (2440). 即,在一方面中,当牙冠点移动的方向与该点处表面内法向之间的角度大于预定义临限SC时,便可将该牙冠点视为有效牙冠表面。 That is, in one hand, when the angle of the direction of movement of the surface of the crown point within the normal at this point is greater than the predefined threshold SC, the crown can be considered a valid point crown surface. 再次参照图24,确定牙齿的阻力表面,牙齿的阻力表面是具有至少一个顶点V且其中S(V)小于预定义SR的所有牙根表面的集合(2450)。 Referring again to FIG. 24, to determine the resistance of the surface of the tooth, the surface resistance having at least one tooth and wherein the vertex V S (V) is smaller than a predefined SR all root surfaces of the collection (2450). 在另一方面中,若牙根点移动的方向与该点处的表面内法向之间的角度大于预定义SR,则可将该牙根点视为位于阻力牙根表面上。 On the other hand, if the root point moves in the direction normal to the inner surface and the angle at that point is greater than the predefined SR, can be seen as the root point is located on the root surface resistance.

[0184] 再次参照图24,可将比例G确定为有效表面与阻力表面的面积比例(2460)。 [0184] Referring to FIG. 24 again, you can determine the percentage of G and the effective surface area ratio of the surface resistance (2460). 若比例G大于预定义有效-阻力阈值AR,则可无需任何附件(2470)。 If the ratio is greater than a predefined effective G - resistance threshold AR, may not need any accessories (2470). 例如,在一方面中,若牙冠有效表面积与牙根阻力表面积的比例大于预定义有效-阻力阈值AR,则可将该移动视为可行。 For example, in one aspect, if the ratio of effective surface area of the crown and root resistance of the surface area is greater than the predefined effective - resistance threshold AR, the move may be considered as viable. 另一方面,若比例G不大于AR,则使用对牙冠表面的最小度添加,以使重新计算的比例G满足G > AR的条件(2480)。 On the other hand, if G is not greater than the proportion of AR, using the minimum degree of crown surface added to make the ratio of the recalculated G satisfy G> AR conditions (2480). 可将该添加制作成附件(除其他以外,如脊状部分、突出部分或陷窝),且可使该附件与牙冠啮合。 The attachments can be added to make (among other things, as part of the ridge, protrusion or lacunae), and allows the attachment and engagement crown.

[0185] 根据一实施例,使用非重复性过程以根据治疗计划为合意的移动确定矫正器的近最佳形状。 [0185] According to an embodiment, the use of non-repetitive procedure to be desirable to move the aligner is determined according to the treatment plan nearly optimal shape. 图25是非重复性过程800的流程图。 Non reproducibility of the process flowchart of FIG. 25 800. 针对基本的形状特征(例如,陷窝),在步骤810处,计算该特征所形成力的量值,该量值是该特征于矫正器表面上的位置以及特征凸起程度的函数。 For the basic shape characteristics (e.g., dimples), at step 810, calculate the magnitude of the force which the feature is formed, characterized in that the magnitude is the location and characteristics of the projection on the surface of the aligner function of the degree. 可藉由将特征位置的几何特性(例如,至边界的距离、至曲折脊状部分的距离、曲率等)与该特征所产生力的量值相联系,以统计的方式导出该函数。 Can be characterized by the geometric characteristics of the location (e.g., the distance to the boundary, to the zigzag-shaped portion of the ridge distance, curvature, etc.) and the magnitude of the force generated by the feature linked to the function derived statistical manner. 针对自阶段η 至阶段η+1的给定牙齿移动,在步骤820处,计算对应于给定移动的经由阻力中心的旋转轴及平移向量。 Since the phase to phase for η η + 1 given tooth movement, at step 820, the calculation corresponding to a given movement through the rotation axis and the translation vector of the center of resistance. 接下来,在步骤830处,识别牙齿表面上将对其施加力的点,且计算该等力的量值,以使若该等量值的力沿其自阶段η至阶段η+1的移动轨迹的方向施加于识别点,则下列条件已得到满足: Next, at step 830, to identify a tooth surface will apply a force to its point, and the computing power of such a magnitude, so that if the magnitude of such a force along its self η phase to mobile phase η + 1 direction of the track is applied to the recognition site, the following conditions have been met:
