背景技术 Background

[0003] 本发明大体上涉及正畸学领域,且更明确地说,涉及用于啮合牙科重定位器具的牙齿附件,所述附件具有为个别患者定制的改进或优化的设计参数和/或几何形状,且/或用于选定的所要力系的改进施加以引起所识别的牙齿移动。 [0003] The present invention relates generally to the field of orthodontics and, more specifically, relates to relocation for engaging a dental appliance dental accessory, the accessory has customized for individual patients improved or optimized design parameters and / or geometry shape, and / or improved for the selected desired force system is applied to cause tooth movement identified.

[0004] 正畸学的目标是将患者的牙齿移到功能和/或美学最优化的位置。 [0004] The goal of orthodontics is to move the patient's teeth function and / or aesthetics optimized position. 传统上,正畸医生或牙医将例如牙箍等器具施加到患者的牙齿,且牙箍组将连续的力施加在牙齿上,并逐渐将牙齿推向其预期的位置。 Traditionally, the orthodontist or dentist braces and other devices will be applied for example to the patient's teeth and braces group continuous force is applied on the teeth, and the teeth gradually into its intended position. 随着时间过去且在一系列的就诊和对牙箍的调整之后,正畸医生调整器具以使牙齿朝其最终目的地移动。 Over time and after a series of visits and adjustments to braces, orthodontists adjust the appliance to make moving toward its final destination teeth.

[0005] 更近一些,用传统固定器具(例如牙箍)进行的常规正畸治疗的替代方案已变得可用。 [0005] More recently, an alternative to conventional therapy with conventional fixed orthodontic appliances (e.g., braces) performed has become available. 举例来说,包含一系列预制对准件的系统在商业上已可从加利福尼亚州圣克拉拉市的矫正技术公司(Align Technology, Inc.,)以商标Invisalign®系统购得。 For example, it contains a series of pre-aligner system is available from Santa Clara, Calif correction technology company (Align Technology, Inc.,) trademark Invisalign® system available commercially. Invisalign® 系统描述于转让给矫正技术公司的大量专利和专利申请案中,例如包含在第6,450,807号和第5,975,893号美国专利中,以及该公司的网站上,所述网站可在万维网上访问(例如见网址“align, com”)。 Invisalign® system is described in the transfer of technology to correct the company's large number of patents and patent applications, for example, contained in No. 6,450,807 and US Patent No. 5,975,893, as well as on the company's website, the Web site can be accessed on the World Wide Web (see for example web site "align, com"). Invisalign®系统包含在将对准件施予患者并用于重定位牙齿(例如在治疗开始时)之前设计和/或制造将由患者佩戴的对准件中的多个且有时所有对准件。 Invisalign® system is contained in the aligner administered to a patient and for the relocation of teeth (for example at the beginning of treatment) before designing and / or alignment of parts manufacturing will be worn by patients with multiple and sometimes all of the alignment member. 通常,为患者设计和规划定制治疗会利用基于计算机的3维规划/设计工具,例如可从矫正技术公司购得的软件技术。 Typically, patients planning custom design and treatment will use a computer-based three-dimensional planning / design tools, for example, from correction technology company acquired software technology. 对准件的设计可依赖于对一系列经规划连续牙齿布置的计算机建模,且将个别对准件设计为佩戴在牙齿上,且将牙齿弹性地重定位到所规划的牙齿布置中的每一者。 The alignment member is designed to rely on computer modeling of a continuous series of teeth arranged by planning and design of the individual aligner worn on the teeth, and the teeth resiliently relocated to the planned arrangement of each tooth one.

[0006] 正畸器具和系统通常利用接合在牙齿表面上的牙齿附件或组件,以便引起所要的牙齿移动。 [0006] The orthodontic appliances and systems typically utilize bonded to the tooth surface tooth attachments or components, so as to cause tooth movement desired. 一般来说,器具将力和/或力矩施加于牙冠上以移动牙齿,其中所施加的力通常与牙齿表面或定位于牙齿上的附件垂直。 In general, the appliance will force and / or torque applied to move the tooth, wherein the applied force is generally perpendicular to the tooth surface or attachment is positioned on the tooth crown. 目前,正畸系统通常使用若干通用或标准附件来实现正畸牙齿移动。 Currently, orthodontic systems typically use a number of common or standard accessories to achieve orthodontic tooth movement. 可识别牙齿移动,且接着选择通用或标准附件来结合重定位器具而使用。 Tooth movement can be identified, and then select the generic or standard accessory to combine relocation appliance use. 附件的选择和定位通常是基于治疗专家的临床经验或根据治疗专业人员的判断来实现。 Selection and positioning attachment is usually based on clinical experience or based on expert judgment of the treating professionals to achieve. 遗憾的是,事实证明,在一些情况下此些当前方法的疗效有限,因为牙齿上的选定附件配置和/或定位可能无法递送最佳或甚至充分的力施加,以便引起所要的牙齿移动。 Unfortunately, it turns out, in some cases, some of the current limited efficacy of this approach, because the selected attachment on the tooth configuration and / or location may not be the best or even deliver sufficient force to cause tooth movement desired. 在一些情况下,施加到牙齿的实际力并不如最初所预期,且可能导致缺乏移动或不正确且不想要的牙齿移动。 In some cases, the actual force applied to the tooth is not as originally expected, and may lead to a lack of movement or incorrect and the desired tooth movement. 用于旋转的当前牙齿附件对于所有患者均具有相同形状和位置,且用旋转组件来使牙齿经历移动。 Dental attachment for a rotary current for all patients have the same shape and location, and a rotary assembly to move the teeth experience. 由于牙齿的个别形态和复合移动,此些附件的性能可能不是对于所有患者都是最佳的。 Since the individual shape of the teeth and composite movement, this attachment may not be some performance is the best for all patients.

[0053] 本发明提供正畸系统和相关方法,其用于设计和提供用于引起所要牙齿移动且/ 或将牙齿重定位成所要布置的改进或更有效的牙齿移动系统。 [0053] The present invention provides an orthodontic system and related method for designing and providing for eliciting the desired tooth movement and / or relocation to the desired tooth arrangement improved or more efficient tooth movement system. 本发明的方法和正畸系统包含牙齿附件,其具有为更佳且/或更有效地施加力以获得所要/选定正畸移动而选择或修改的改进或优化的参数。 The method and system of the present invention comprises orthodontic tooth attachments, which has a parameter for the better and / or more effective application of force to achieve the desired / selected orthodontic movement selected or modified to improve or optimize. 本发明的附件可为特定患者(例如患者定制)、特定移动和/或患者子群组或子组而定制,且经配置以啮合由患者佩戴的正畸牙齿定位器具,其中附件与正畸器具之间的啮合导致将重定位力或力系列/系施加于带有附件的牙齿,且通常将引起牙齿移动。 Annex to the present invention may be a particular patient (such as a patient customized), specific movement and / or sub-group or sub-group of patients is customized and configured to engage the patient wears orthodontic tooth positioning appliance, including accessories and orthodontic appliances engagement between the forces led to the relocation or force Series / Department applied to the teeth with attachments, and typically will cause tooth movement.

[0055] 参看图IB进一步说明用于传递移动力或力系的牙齿附件。 [0055] Referring to Figure IB further described tooth attachment for transmitting the moving force or system of forces. 所述附件在牙冠上耦合到牙齿表面,且当器具由患者佩戴时,可如图IA中所说明与牙科器具或对准件耦合或啮合牙科器具或对准件。 The crown is coupled to the attachment on the tooth surface, and when the appliance is worn by the patient, can be illustrated in Figure IA in the dental appliance or aligner coupled or engaged with dental appliances or aligners. 当由患者佩戴时,器具通过激励件(例如器具内腔的一个或一个以上表面或部分)与牙齿附件和/或牙冠的对应表面/部分之间的相互作用/接触而啮合牙冠和附件,以施加力系用于引起牙齿移动。 When worn by the patient, the appliance by energizing member (such as an appliance lumen or more surfaces or in part) and tooth attachments and / or crown corresponding surface / interaction / contact portion and the engagement between the crown and Accessories to apply a force system for causing tooth movement. 如下文进一步所述,可实现各种牙齿移动。 As described further below, can achieve a variety of tooth movement.

[0056] 如现有申请案中所陈述,可将器具设计和/或提供为一组多个器具中的一部分, 且可根据治疗计划来管理治疗。 [0056] As set forth in the prior application case, the appliance can be designed and / or provided as a part of the plurality of instruments, and may be managed according to the treatment plan to the treatment. 在此实施例中,每一器具可经配置以使得一个或一个以上牙齿接纳腔具有对应于既定用于所述器具的中间或最终牙齿布置的几何形状。 In this embodiment, each appliance may be configured such that one or more tooth receiving cavity has a geometry corresponding to the appliance intended for intermediate or final tooth arrangement. 器具几何形状可进一步设计或修改(例如修改以适应牙齿附件或结合牙齿附件而操作),以便将所要的力或力系施加到患者的牙齿,且引起所要的牙齿移动且将牙齿逐渐地重定位到既定布置。 Instrument geometries may be further designed or modified (for example adapted to the tooth attachment or binding tooth attachments and operating) in order to be in force or system of forces applied to the patient's teeth and cause the desired tooth movement and teeth gradually relocate to a predetermined arrangement. 通过将一系列递增位置调整器具放于患者的牙齿上,可渐进地将患者的牙齿从其初始牙齿布置重定位到最终牙齿布置。 By a series of incremental position adjustment appliances placed on the patient's teeth, can progressively patient's teeth from an initial tooth arrangement to a final tooth arrangement relocation. 可全部在同一阶段或成组或分批(例如在治疗阶段开始时)制造调整器具,患者佩戴每一器具,直到不再能感觉到每一器具在牙齿上的压力为止。 May all group or batch (for example, at the beginning of the treatment phase) adjustment appliance manufacturing, the patient wears each appliance until you can no longer feel the pressure of each appliance on the tooth at the same stage or as far. 可在患者佩戴多个不同器具(例如一组器具)中的任一器具之前,设计乃至制造所述多个器具。 Before the patient can wear a number of different devices (e.g. a set of instruments) to any one of the appliance, the design and the manufacture of the plurality of instruments. 此时,患者用系列中的下一调整器具来替换当前调整器具,直到没有器具剩下为止。 In this case, the patient with a series of next adjustment appliance to replace the current adjustment appliance until no rest until the appliance. 所述器具通常未固定到牙齿上,患者可在疗程期间的任何时间放置和替换器具。 The appliance is usually not fixed to the teeth, the patient can be placed at any time and replace the appliance during treatment. 系列中的最终器具或若干器具的几何形状可能经选择而过度校正牙齿布置,即具有(如果完全实现)将移动个别牙齿超过已选择为“最终”的牙齿布置的几何形状。 Geometry series final appliance or several appliances may be selected and overcorrected tooth arrangement, which has (if fully achieved) move individual teeth than is selected as the "final" of the geometry of the tooth arrangement. 此过度校正可能合乎需要,目的是在重定位方法终止之后抵消潜在的复归,即准许个别牙齿朝其预校正的位置往回移动。 This over correction may be desirable, the purpose of the relocation was terminated after offsetting the potential return, that allow individual teeth to move back toward its pre-correction position. 过度校正还可能有助于加快校正速率,即通过使器具的几何形状的位置超过所要中间或最终位置的几何形状,个别牙齿将以较大速率朝所述位置移位。 Over correction may also help speed up the correction rate, that is geometric shape of the intermediate or final position of the position by the appliance exceeds the desired geometric shape, a larger rate of individual teeth will shift toward the position. 在此些情况下, 在牙齿到达器具所界定的位置之前,就可以不再使用器具。 Under these circumstances, the position of the teeth before arrival appliance as defined, you can no longer use the appliance.

[0057] 例如图IA中所说明的正畸器具在器具的牙齿接纳腔与所接纳的牙齿和/或附件之间的每一接触点处将力施加到牙齿的牙冠和/或定位在牙齿上的附件。 Crown and / or positioning [0057] Figure IA an orthodontic appliance such as those described in each point of contact between the teeth receiving cavity appliances and accepted the teeth and / or attachment force is applied to the teeth in the tooth accessory. 这些力中的每一者的量值及其在牙齿表面上的分布决定了其所导致的正畸牙齿移动的类型。 The magnitude and distribution of each of these forces on the tooth surface determines the type of orthodontic tooth movement they cause. 牙齿移动的类型按照惯例被描绘为挤出、侵入、旋转、翻转、平移和牙根移动。 Type of tooth movement by convention is depicted as extrusion, intrusion, rotate, flip, pan, and root movement. 牙冠移动大于牙根移动的牙齿移动被称为翻转。 Tooth root movement more than crown movement move is called flipping. 牙冠和牙根的等量移动被称为平移。 Crown and root of the same amount of movement is called panning. 牙根移动大于牙冠移动被称为牙根移动。 Root movement more than crown movement is called root movement.

[0058] 出于说明性目的,可将三种类型的牙齿移动识别为连续的可能移动的划分。 [0058] For illustrative purposes, the three types of tooth movement is recognized as a continuous division may move. 牙齿移动可在空间的任一平面中在任一方向上。 Tooth movement in any plane in space in either direction. 本发明使用将三维空间中的移动描绘为三种分类:第一级、第二级和第三级的正畸惯例。 The present invention uses a three-dimensional space of movement is depicted as three categories: first grade, second and third stages of orthodontic practice.

[0059] 所选择和施加到牙齿的力的量值,以及力在其上作用的牙齿表面上的位置和分布的合适选择对于控制所实现的牙齿移动的类型来说是重要的。 [0059] The selected and applied to the teeth, amount of force, and force its position on the tooth surface and on the role of the proper selection of the distribution is important for the type of control of tooth movement is achieved. 先前存在的附接技术并不用于为个别患者或所要的特定牙齿移动定制附件,或优化或精确地控制施加到患者的牙齿以引起牙齿的所要移动的力(例如力的集合或力系)。 Previously existing attachment technology is not used for an individual patient or a particular attachment to be customized tooth movement or optimization or precise control is applied to the patient's teeth to cause a force (for example, a collection of force or system of forces) of the teeth to be moved.

[0060] 利用附件的现存正畸系统和方法通常利用有限数目个通用或标准附件来实现正畸牙齿移动。 [0060] existing orthodontic system and method of attachment often use a limited number of common or standard accessories to achieve orthodontic tooth movement. 根据先前存在的方法,可基于所需的牙齿移动的类型来选择所使用的通用或标准附件,而不进行预测或力建模查询(例如见图2A)。 The method of pre-existing, based on the type of tooth movement required to select the generic or standard accessories used without modeling to predict or force a query (for example, see Figure 2A). 举例来说,正畸知识或临床实践可使得正畸从业者从一组现存通用附件中选择一特定附件,其中所述附件是已知或预期更适合于所要的牙齿移动。 For example, knowledge or clinical practice orthodontics orthodontic practitioner can make a specific choice from a group of existing common accessory attachment, in which the attachment of tooth movement is known or expected to be more suitable for the. 然而,此特定选择在按患者或牙齿移动定制的治疗方面受限(例如因为选择的数目有限),且与本文所描述的附件设计的“定制”不同。 However, this particular choice by patient or dental treatment customized mobile restricted (for example, because the choice of a limited number), and the attachment described herein designed "custom" different. 更通常且在许多治疗方法中,针对所有患者的所有牙齿上的相同移动使用单个或相同的通用附件设计/配置;“均码(one size fitsall) ”方法。 More generally, and in many treatment methods, for the same move all the teeth on all patients using a single or the same general attachment design / configuration; "Size (one size fitsall)" method. 虽然将用于移动的附件的选择按照惯例是基于临床经验的一般指导原则或基于治疗专业人员的判断,但执行选定附件对引起所要移动所需的力系的较少优化/定制,且将由选定附件和位置实现的实际力系是在使用之后(例如)通过观察临床结果来评估。 Although general guidelines for the selection moved attachments by convention is based on clinical experience or judgment of the treating professional based, but the implementation of the selected attachment to the cause to be required to move less force system optimization / customization, and by The actual force system selected attachment and position is achieved after use (for example) by the clinical results to evaluate.

[0061] 由此,先前通过使用牙科附件来实现牙齿移动的方法已被证实在一些情况下具有缺点,因为其并未最佳地将生物力学、力建模和/或预测性建模的原理并入到附件的设计中。 [0061] Thus, the methods previously achieved by the use of dental accessory tooth movement has been confirmed to have a disadvantage in some cases, because of the principles it has not the best biomechanics, strength modeling and / or predictive modeling incorporated into the design of its annexes. 因此,一般或非定制附件所施加的实际移动力的所得不确定性有时可能导致不足和/ 或不适当的力系被施加到牙齿,这可能导致不正确且不想要的牙齿移动。 Therefore, the resultant force of the actual movement or customized attachments generally applied uncertainty may sometimes result in insufficient and / or inappropriate force system is applied to the teeth, which could lead to incorrect and the desired tooth movement. 本发明有利地实现牙齿的给定所要移动,针对所要/指定移动而优化例如附件几何形状和附件的定位等各种附件参数。 The present invention advantageously achieve given teeth to be moved for the desired / specified range of accessories such as mobile optimized geometry parameters Positioning Accessories and attachments and the like. 此优化过程不仅基于所要牙齿移动,而且可在确定附件的特性的过程中并入生物力学、生物力学与力测试和/或建模的原理,以及待移动的特定牙齿的特性。 This optimization process is not only based on the desired tooth movement, and can be incorporated in determining the biomechanical properties of the attachment process, the principles of biomechanics and strength testing and / or modeling, and to be specific characteristics of tooth movement. 可基于个别患者的待移动的特定牙齿的特性而实现进一步定制。 It can be based on characteristics of the individual patient's specific tooth movement and to achieve further customization. 图2B大体上说明附件设计优化的过程。 Figure 2B generally illustrate accessory has been designed to optimize the process. 可通过并入有或考虑个别患者(或患者群组)的牙齿的特性,例如牙齿大小、宽度、轮廓、长度、长轴等来实现附件设计定制。 Or by incorporating consideration of the individual patient (or the patient group) teeth characteristics, e.g., tooth size, width, contour, length, etc. to achieve the long axis design custom attachments. 如图2B中所说明,本发明可包含:识别所要牙齿移动;确定引发所要牙齿移动所需的力系或一系列的所施加力;以及设计经优化的附件以将所识别的力系或大体上类似的力系递送到患者的牙齿,从而实现所要的牙齿移动。 As illustrated in Figure 2B, the present invention may comprise: identifying a desired tooth movement; determining the desired tooth movement caused the desired force system or a series of applied force; and accessory design optimized to force system or generally identified On a similar force system delivered to the patient's teeth in order to achieve the desired tooth movement. 如本文进一步陈述,附件设计和优化可包含对使用选定附件施加到牙齿的力系进行建模或预测, 且可进一步包含修改或调整一个或一个以上附件参数。 As further stated, accessory design and optimization may include the use of selected attachment force system is applied to the teeth to model or predict, and may further include modifications or adjustments attachment of one or more parameters. 在一个实施例中,一种方法可包含: 首先选择附件设计;且接着确定通过附件的正畸使用而施加到牙齿的力系;且进一步确定所预测的力系是否适合于引发所要的牙齿移动。 In one embodiment, a method may include: first select the attachment design; and then determined by the use of orthodontic attachment system of forces applied to the teeth; and further determining whether the predicted force system is adapted to initiate the desired tooth movement .

[0083] 在具有每颗牙齿的开始位置和最终位置两者后,过程接下来为每颗牙齿的运动界定牙齿路径(步骤150)。 [0083] In each tooth having a starting position and end position of the latter two, the process of defining the next tooth paths for each tooth movement (step 150). 在一个实施例中,可总体优化牙齿路径,使得牙齿以最快方式移动,同时使迂回翻转的量最少,以使牙齿从其初始位置到达其所要的最终位置。 In one embodiment, the teeth may optimize the overall path, so that the fastest way to move the teeth, while the minimum amount flip detour to reach the final position of the teeth to which it from its initial position. 迂回翻转是牙齿在不同于直接朝所要最终位置的任何方向上的任何移动。 Flip roundabout is different from the direct any teeth in any direction to move in the desired final position of. 迂回翻转有时是必要的以允许牙齿移动经过彼此。 Flip roundabout is sometimes necessary to allow the teeth to move past each other. 对牙齿路径进行分段。 Tooth path segment. 计算分段,使得每颗牙齿在一分段内的运动保持在线性和旋转平移的阈值限制内。 Computing segments such that each tooth movement in a segmented holding within linear and rotational translation of the threshold limit. 以此方式,每一路径分段的端点可构成临床上可行的重定位,且分段端点的聚合构成临床上可行的牙齿位置序列,使得从序列中的一点移动到下一点不会导致牙齿的碰撞。 In this way, each path segment endpoints may constitute clinically feasible relocations, and segment endpoints polymerization viable clinical tooth position in the sequence constituting such cause tooth from a sequence that will not move to the next point collision.

[0084] 在一个实施方案中,基于待使用的器具的性质而用默认值来初始化线性和旋转平移的阈值限制。 [0084] In one embodiment, based on the nature of the instruments to be used and the default value to initialize the threshold limits of linear and rotational translation. 可使用患者特定数据来计算更个人化定制的限制值。 It can be calculated more personal customization limit the use of patient-specific data. 还可基于器具计算的结果来更新限制值(步骤170),其可确定在沿一个或一个以上牙齿路径的一个或一个以上点处,可由器具在牙齿和组织的当时存在的配置上产生的力不可能影响由一个或一个以上牙齿路径分段表示的重定位。 Can also be used to update the limit value (step 170) based on the results of the calculation of the appliance, which can be determined along one or more teeth or more path point, the force can be appliance configuration exists at the time of generation of teeth and tissue unlikely to affect relocation by one or more dental path segment represented. 使用此信息,界定经分段路径的子过程(步骤150)可重新计算路径或受影响的子路径。 Using this information, the segmented path defined sub-process (step 150) to recalculate the route or affected sub-paths.

[0085] 在所述过程的各个阶段,且明确地说,在已界定经分段路径之后,所述过程可以且通常将与负责患者的治疗的临床医师互动(步骤160)。 [0085] In the various stages of the process, and specifically, after having defined segmented path, the process can and often will interact with the clinician responsible for the treatment of patients (step 160). 可使用经编程以从其中实施过程100的其它步骤的服务器计算机或进程接收牙齿位置和模型以及路径信息的客户端进程来实施临床医师互动。 In other steps of the implementation process from which a server computer or process 100 receives tooth positions and models, and client process to implement path information may be used by clinicians interactive programming. 有利地编程客户端进程以允许临床医师显示位置和路径的动画,且允许临床医师重设牙齿中的一者或一者以上的最终位置,且指定待应用于经分段路径的约束。 The client process is advantageously programmed to allow the clinician to display the location and path of animation, and allows clinicians to reset the teeth of one or more of the final position, and the specified constraints to be applied to segmented paths. 如果临床医师作出任何此类改变,那么再次执行界定经分段路径的子过程(步骤150)。 If the clinician to make any such changes, then the implementation of the definition of sub-segmented path process again (step 150).

[0086] 使用经分段牙齿路径和相关联的牙齿位置数据来计算临床上可接受的器具配置(或器具配置中的连续改变),其将使牙齿以由路径分段指定的步长在所界定的治疗路径上移动(步骤170)。 [0086] The segmented teeth and tooth position path data associated with calculating clinically acceptable instrument configuration (or appliance configurations continuously changing), which will enable the teeth to the segment specified by the path in the step Mobile (step 170) defined treatment path. 每一器具配置表示沿针对患者的治疗路径的步长。 Each appliance configuration represents a path along for the treatment of patients with steps. 界定且计算步长, 使得每一离散位置可遵循直线牙齿移动或从由前一离散步骤实现的牙齿位置的简单旋转, 且使得每一步长所需的重定位的量涉及患者的牙系上的正畸学上最优量的力。 Defining and calculating step, so that each discrete position can follow a straight line tooth movement or simple rotation from the tooth positions from the previous discrete steps implemented, and such that the amount of the relocation of each step required for the system relates to a patient's teeth optimal amount of force on orthodontics. 如同路径界定步骤一样,此器具计算步骤可包含与临床医师互动且甚至反复互动(步骤160)。 As defined step path like this appliance calculation step may include interaction with clinicians and even repeated interaction (step 160). 下文将参看图IOB更全面地描述过程步骤200中实施此步骤的操作。 Referring to FIG IOB will hereinafter more fully described embodiment of the process of step 200 in the operation of this step.

[0087] 在计算器具界定之后,过程100可进行到制造步骤(步骤180),其中制造由所述过程界定的器具,或产生电子或印刷信息,其可由人工或自动过程使用以界定器具配置或改变器具配置。 [0087] After calculating instruments define the manufacturing process may proceed to step 100 (step 180), where the manufacturing process is defined by the appliance, or generate electronic or printed information, which may be manual or automated process to define appliance configurations or use change the appliance configuration.

If the current aligner shape is by far the best candidate, the process to determine whether good enough to be accepted (step 270). If it is, then the process exits. Otherwise, the process continues and calculates another candidate shape (step M0) for analysis.

15[0092] 接着以计算方式操纵模型对准件,以将其放置于模型颚中的经建模牙齿上,以创建处于适当位置的对准件的复合模型(步骤340)。 15 [0092] and then manipulate the model to calculate the alignment of the pieces to be placed on the model by modeling the jaw teeth in place in order to create a composite model of the aligner (step 340). 任选地,计算使对准件变形以配合在牙齿(包含附接到牙齿的任何硬件)上所需的力,且在测量特定对准件配置的可接受性时将其用作优值。 Optionally, calculate the alignment member is deformed to fit the teeth (including any hardware attached to the tooth) is required on the force, and in measuring it as excellent value for a particular configuration of the acceptability of the aligners when. 任选地,所使用的牙齿位置如基于先前治疗步骤和其它患者信息从概率模型估计所得。 Optionally, the tooth position as previously used treatment procedures and other patient information resulting from the estimate based on a probability model. 然而,在较简单的替代方案中,通过将足够的力施加到对准件内侧以使其足够大以配合在牙齿上、将模型对准件放置在复合模型中的模型牙齿上、将模型牙齿和组织的条件设置为无比坚硬,且允许模型对准件松弛到固定牙齿上的适当位置中,来对对准件变形进行建模。 However, a simpler alternative, by a sufficient force is applied to the inner side of the alignment member so that it is large enough to fit on the teeth, the model aligner placed in the composite model of model teeth model teeth and organizational conditions to very hard, and allow the model to relax to the alignment member fixed in place on the tooth to be modeled on the alignment deformation. 对对准件和牙齿的表面进行建模,以在此阶段无摩擦的情况下相互作用,使得对准件模型在有限元分析开始之前实现模型牙齿上的正确初始配置,以找到复合模型的解决方案,且计算牙齿在扭曲的对准件的影响下的移动。 Aligner and the tooth surface modeling, to interact at this stage without friction, so that the aligner model in a finite element analysis before the start of the initial configuration to achieve the correct model teeth, to find solutions to complex model program, and the calculated tooth movement under the influence of distorted aligner.

[0093] 图12展示用于计算可用于对准件计算(如过程200 (图10B)的步骤MO中所描述)中的下一对准件的形状的过程400。 [0093] Figure 12 shows the alignment member may be used for calculating a calculation (e.g., process 200 (FIG. 10B) as described in step MO) process the next shape of the alignment member 400. 使用多种输入来计算下一候选对准件形状。 To calculate the next candidate aligner shape using a variety of inputs. 这些输入包含通过对复合模型的有限元分析解决方案产生的数据的输入402,以及由当前牙齿路径界定的数据404。 These inputs contain a finite element analysis model of the complex data generated input solution 402, and the data path defined by the current 404 teeth. 从有限元分析得出的数据402包含:牙齿的模拟重定位发生的真实逝去时间量;通过所述分析计算的实际最终牙齿位置;施加到每颗牙齿的最大线性和扭转力;以及每颗牙齿的最大线性和角速度。 Obtained from finite element analysis data 402 includes: Analog tooth relocations real amount of elapsed time of occurrence; the actual final tooth position calculated by the analysis; applied to the maximum linear and torsional force per tooth; and each tooth maximum linear and angular velocity. 根据输入路径信息,输入数据404包含当前路径分段的初始牙齿位置、当前路径分段结束时的所要牙齿位置、每颗牙齿的最大可允许移位速度,以及针对每颗牙齿的每一种类的最大可允许力。 Based on the input path information, input data 404 contains the current path segment of initial tooth positions, the desired position of the teeth at the end of the current path segment, the maximum allowable each tooth displacement speed, and for each category of each tooth The maximum allowable force.

[0094] 如果发现先前估算的对准件违反一个或一个以上约束,那么过程400可任选地使用额外输入数据406。 [0094] If it is found in violation of a previous estimate of aligners one or more constraint, then the process 400 can optionally use additional input data 406. 此数据406可包含识别先前所估算的对准件所违反的约束以及先前所估算的对准件的任何所识别次最优性能的信息。 This data may include identifying constraints 406 aligner violated previously estimated and any identified sub-optimal performance of the previously estimated aligner information. 另外,过程400可使用与先前牙科装置所违反的约束以及先前牙科装置的次最优性能有关的输入数据408。 In addition, the process 400 can be used with the prior restraint in violation of the dental device and prior suboptimal performance dental device 408 related to the input data.

[0095] 在接收到初始输入数据(步骤420)后,过程在模型中的可移动牙齿上重复。 [0095] In receiving the initial input data (step 420), the process is repeated on the model of the movable teeth. (可将所述牙齿中的一些牙齿识别为且强迫为不可移动的。)如果由先前选择的对准件引起的当前选择的牙齿的最终位置和运动动态为可接受(步骤440的“是”分支),那么过程通过选择考虑下一牙齿(步骤430)而继续,直到已考虑所有牙齿为止(从步骤430到步骤470 的“完成分支”)。 (May be some of the tooth and the tooth is forced to recognize immovable.) If the previously selected aligner causes the currently selected final tooth position and dynamic motion acceptable (step 440 of "YES" branch), the process by selecting the consideration of the next tooth (step 430) and continues until all the teeth have been considered so far (from step 430 to step "to complete the branch" 470). 否则(来自步骤440的“否”分支),计算对准件在当前选择的牙齿的区中的变化(步骤450)。 Otherwise (step 440 from the "No" branch), calculate the change aligner (step 450) in the currently selected tooth area. 过程接着移回到选择下一当前牙齿(步骤430)(如已描述)。 The process then moves back to select the next current tooth (step 430) (as already described).

[0096] 当已考虑所有牙齿时,针对先前所界定的约束而估算对对准件作出的总体改变(步骤470),其实例已被提到。 [0096] When all the teeth have been considered when, while estimates for the previously defined constraints to the overall change aligner (step 470), examples of which have been mentioned. 可参考多种进一步考虑(例如可制造性)来界定约束。 Refer to a variety of further consideration (for example, manufacturability) to define constraints. 举例来说,可界定用以设置对准件材料的最大或最小厚度或用以设置对准件在牙齿的牙冠上的最大或最小覆盖范围的约束。 For example, the thickness can be used to define the maximum or minimum set of aligner material, or to set the maximum or minimum coverage of the aligner constraints on the crown of the tooth. 如果满足对准件约束,那么应用改变以界定新的对准件形状(步骤490)。 If the aligner constraints, then apply the changes to the definition of a new aligner shape (step 490). 否则,调整对准件的改变以满足所述约束(步骤480),且应用经调整的改变以界定新的对准件形状(步骤490)。 Otherwise, the adjustment to change the alignment of elements to satisfy the constraint (step 480), and change the application adjusted to define a new aligner shape (step 490).

[0097] 图13A说明计算当前牙齿区中的对准件改变的步骤(图12中的步骤450)的一个实施方案。 [0097] FIG 13A illustrates the calculation of the current tooth zone of step (step 450 in FIG. 12) to change the alignment of an embodiment. 在此实施方案中,使用基于规则的推断引擎456来处理先前所述的输入数据(输入454)以及规则的规则库452中的一组规则45¾到452η。 In this embodiment, the use of a rule-based inference engine 456 to process the input data previously described (input 454) and the rules of rule base 452 to a set of rules 45¾ 452η. 推断引擎456和规则452 界定产生系统,其在应用于事实输入数据时产生一组输出结论,所述输出结论指定将对当前牙齿区中的对准件作出的改变(输出458)。 Inference engine 456 and the rules 452 define the generating system, which generates a set of output conclusions when applied to the fact that the input data, the output current will change the conclusions specified tooth region made aligner (output 458).

[0099] 在图1¾和图13C中所说明的替代实施例中,计算对准件的绝对配置,而不是增量差。 [0099] Alternatives 1¾ in FIG. 13C and illustrated embodiment, the calculation of the absolute configuration of the aligner, instead of an incremental difference. 如图13B中所示,过程460计算当前牙齿区中的对准件的绝对配置。 As shown in FIG. 13B, the process 460 calculates the current absolute configuration tooth area of the alignment member. 使用已经描述的输入数据,所述过程计算当前牙齿的所要最终位置与所实现的最终位置之间的差异(步骤462)。 Using the input data has been described, the process of calculating the current difference between the desired tooth position and the final position between the final achieved (step 462). 使用牙齿中心线与牙龈组织的水平之间的交点作为参考点,所述过程计算所有六个运动自由度即三个平移度和三个旋转度的差异的补充(步骤464)。 Use the intersection of the center line of the teeth and gum tissue level as a reference point, the process of calculating all six degrees of motion that is complementary three translational and three rotational degrees of difference (step 464). 接下来,使模型牙齿从其所要最终位置移位补充差异的量(步骤466),其在图13B中所说明。 Next, the model tooth from its final position shifted to supplement the difference amount (step 466), which are illustrated in FIG. 13B.

[0101] 图13C中展示过程460中的另一步骤,其也可实施为规则452(图13A)。 Another step in the process 460 [0101] is shown in FIG. 13C, which may also be implemented as a rule 452 (FIG. 13A). 为了在当前牙齿的中心轴的方向上移动当前牙齿,将界定对准件的所述区的模型牙齿的大小或对准件中针对所述牙齿所允许的空间量制作为在所述过程已决定使牙齿移动远离的区域中较小(步骤465)。 In order to move in the direction of the current tooth current central axis of the teeth, it will define the model aligner teeth the size of the zone or aligners in production as against the amount of space allowed for the tooth has decided in the course of the teeth move away from the area in small (step 465).

[0102] 如图14中所示,针对治疗路径中的一步长而计算对准件的形状的过程200(图10B)是过程600中计算一系列对准件的形状的一个步骤。 [0102] As shown in Figure 14, for the treatment step in the long path of the alignment member and the shape calculation process 200 (FIG. 10B) is calculated in a step 600 a series of process aligner shape. 此过程600开始于初始化步骤602,其中获得初始数据、控制和约束值。 This initialization process 600 begins at step 602, wherein the obtaining initial data, control and constraint values.

[0103] 当已为治疗路径的每一步长或分段找到对准件配置(步骤604)时,过程600确定是否所有对准件均为可接受的(步骤606)。 [0103] When each step of the treatment has been a long path or section to find aligner configuration (step 604) when the process 600 determines whether all the aligners are acceptable (step 606). 如果是可接受的,那么过程完成。 If it is acceptable, then the process is completed. 否则,过程任选地进行一组步骤610,以试图计算一组可接受对准件。 Otherwise, the process is optionally performed a set of step 610, in an attempt to calculate a set of acceptable aligners. 首先,放宽对准件上的约束中的一者或一者以上(步骤61¾。接着,针对具有不可接受对准件的每一路径分段,以新的约束来执行使对准件成形的过程200(图10B)(步骤614)。如果所有对准件现在是可接受的,那么过程600退出(步骤616)。 First, relax the constraints on the alignment member of one or more (step 61¾. Then, for each path having unacceptable aligners segment, with new constraints to the implementation process of forming the alignment member 200 (FIG. 10B) (step 614). If all the aligners are now acceptable, the process 600 exits (step 616).

[0104] 对准件可能出于多种原因而为不可接受,其中的一些原因由所述过程来处置。 [0104] aligner for a variety of reasons may be unacceptable, some of the reasons by the process to dispose of. 举例来说,如果需要任何不可能的移动(步骤620),S卩如果需要形状计算过程200(图10B)实现任何规则或调整均不可用的运动,那么过程600着手执行计算对可对其施加力以实现所需运动的主牙齿的硬件附件的配置的模块(步骤640)。 For example, if any impossible movements were required (step 620), S Jie if desired shape calculation process 200 (FIG. 10B) to achieve any rules or not available to adjust the movement, then the process 600 may proceed to perform calculation applied thereto configuration module main force to achieve the desired tooth movement hardware attachment (step 640). 因为添加硬件可具有大于局部的影 Because adding the hardware may have more than a local movie

17响,因此当将硬件添加到模型时,再次执行过程600的外部循环(步骤642)。 17 ring, so when you add hardware to model, execute process 600 outer loop again (step 642).

[0105] 如果不需要不可能的移动(来自步骤620的“否”分支),那么过程将控制转移到路径界定过程(例如步骤150,图10A),其重新界定治疗路径的具有不可接受对准件的那些部分(步骤630)。 [0105] If no possible move (from step "NO" branch of 620), then the process will transfer control to the path defined process (for example, step 150, FIG. 10A), which redefine the treatment path having unacceptable aligned Those portions of the member (step 630). 此步骤可包含改变治疗路径上的牙齿运动的增量(即改变分段)、改变治疗路径中由一个或一个以上牙齿遵循的路径,或两者皆有。 This step may include changing the incremental tooth movement treatment path (ie change above), change the path path by treatment with one or more teeth follow, or both. 在已重新界定治疗路径之后,再次执行过程的外部循环(步骤63¾。重新计算有利地限于仅重新计算治疗路径的经重新界定部分上的那些对准件。如果所有的对准件现在均可接受,那么过程退出(步骤634)。如果仍有不可接受的对准件,那么可重复所述过程,直到找到一组可接受的对准件或超过反复限制为止(步骤650)。此时,以及在本说明书中描述的过程中的其它点处,例如在计算额外硬件(步骤640)时,过程可与人类操作者(例如临床医师或技术人员)互动,以请求辅助(步骤65幻。操作者提供的辅助可包含:界定或选择待附接到牙齿或骨头的合适附件; 界定所添加的弹性元件以为治疗路径的一个或一个以上分段提供所需的力;建议治疗路径的变更,无论是在牙齿的运动路径方面还是在治疗路径的分段方面;以及批准与操作约束的偏离或操作约束的放宽。 After having to redefine the treatment path, perform the procedure again external loop (steps 63¾. Recalculate advantageously limited only by the treatment path recalculated to redefine those aligner portion. If all the aligners are now acceptable , then the process exits (step 634). If there is still an unacceptable aligner, then the process can be repeated until you find a set of acceptable aligners or repeatedly exceeds limit (step 650). At this time, as well as procedure described in this specification in the other points, such as the calculation of additional hardware (step 640), the process can interact with a human operator (eg, clinician or technician), to request the auxiliary (step 65 magic. operator providing auxiliary may comprise: defining or selecting to be attached to a suitable bone or tooth attachment; added elastic member defining one or more segments that provide the force required treatment path; change proposed treatment path, either or in the treatment path segment in terms of the path of movement of the teeth; relax and approved deviation and operational constraints or operational constraints.

[0106] 如上文所提到,通过输入数据的各种项目来界定和参数化过程600 (步骤60¾。在一个实施方案中,此初始化和界定数据包含以下项目:针对总过程的外部循环的反复限制; 经计算以确定对准件是否足够好(见图10B,步骤270)的优值的规格;对准件材料的规格; 对准件的形状或配置成为可接受的而必须满足的约束的规格;正畸学上可接受的力和定位运动和速度的规格;初始治疗路径,其包含每一牙齿的运动路径以及将治疗路径分段为若干分段,每一分段由一个对准件实现;安装于牙齿上或另外的任何锚定件的形状和位置的规格;以及牙齿位于其中或其上的颚骨和其它组织的模型的规格(在正描述的实施方案中,此模型由粘性基质流体的模型组成,牙齿嵌入所述模型中,且所述模型具有本质上界定用于所述流体的容器的边界条件)。 [0106] As mentioned above, the input data defined by the parameters of the various projects and process 600 (step 60¾ In one embodiment, this initialization and defining data includes the following items: external loop repeatedly for the overall process restrictions; calculated to determine the specifications aligner is good enough (see Figure 10B, step 270) is excellent value; specification aligner material; aligner shape or configuration of an accepted constraints that must be met specifications; on orthodontics acceptable force and positioning movement and speed specifications; initial treatment path, which sports path includes every tooth and the treatment path segment into several segments, each segment by an alignment member realization; mounted on the shape and position of teeth or specifications for any additional anchors; and teeth located where the jaw bone or a specification of the model and other organizations (in the embodiment being described, this model consists of a viscous The composition of the fluid model matrix, embedded in the dental model, and the model has a container for the fluid essentially defined boundary conditions).

[0107] 可利用各种牙根成像和/或建模(例如统计牙根建模)。 [0107] can utilize a variety of root imaging and / or modeling (such as statistical modeling root). 可部分地使用基于牙根的排序系统来引导牙齿移动。 Can be partially based root of a ranking system to guide tooth movement. 在一个实施例中,移动受表面积约束限制,而在另一实施例中,移动受体积约束限制。 In one embodiment, the surface area by moving constraint, and in another embodiment, by moving the volume constraints.

[0108] 任选地,将其它特征添加到牙齿模型数据集,以产生对准件中的所要特征。 [0108] Optionally, add other features to the tooth model data set, in order to produce the desired aligners feature. 举例来说,可能希望添加数字蜡补丁以界定腔或凹座以维持对准件与牙齿或颚的特定区之间的空间。 For example, the space may want to add digital wax patches to define a cavity or recess in order to maintain alignment of the teeth or jaw member and the particular regions. 还可能希望添加数字蜡补丁以界定波状或其它结构形式,以创建具有特定刚度或其它结构性质的区。 You may also want to add digital wax patches to define corrugated or other structure, to create a region with a specific stiffness or other structural properties. 在依靠产生正模型以产生重定位器具的制造过程中,将蜡补丁添加到数字模型将产生具有相同添加蜡补丁几何形状的正模。 Rely on a positive model to generate relocatable appliance manufacturing process, adding a wax patch to the digital model will produce the same added wax patch geometry mold having positive. 这可在界定对准件的基本形状中或在计算特定对准件形状中全局进行。 This can be defined in the basic shape of the aligner or in the calculation of specific aligner shape the global conduct. 可添加的一个特征是围绕牙龈线的缘边,其可通过在根据其制造对准件的数字模型牙齿的牙龈线处添加数字模型线而产生。 A feature that can be added is a rim around the gumline, which can be added according to the digital model wire at the gumline of manufacturing the alignment member to generate a digital model of the tooth. 当通过将聚合物材料压力配合于数字牙齿的正物理模型上来制造对准件时,沿牙龈线的线致使对准件具有围绕其的缘边,从而沿牙龈线提供额外的刚度。 When the polymer material by press fit in a positive physical model of the digital teeth aligner manufactured up along the gum line of the line so that the alignment member has around its rim, to provide additional stiffness along the gumline.

[0109] 在另一任选制造技术中,将两个或两个以上材料薄片压力配合于正牙齿模型上, 其中所述薄片中的一者是沿对准件的顶点牙弓切割,且其它薄片上覆于其上。 [0109] In another optional fabrication technique, two or more sheets of material press fit on the positive tooth model in which the sheet is the culmination of one of the arch along the alignment of the cutting element, and the other Cover the sheet thereon. 此举沿牙齿的垂直壁提供至少双重厚度的对准件材料。 The move teeth along the vertical walls of at least double the thickness of the aligner material.

[0110] 可对对准件的设计所作的改变受将用于生产对准件的制造技术约束。 [0110] to change the alignment of the parts of the design made by the technical constraints of production will be used to manufacture the alignment member. 举例来说, For example,

18如果将通过将聚合物薄片压力配合于正模型上来制作对准件,那么对准件的厚度由薄片的厚度决定。 18 If the polymer sheet by press fit onto the positive model production aligner, the thickness of the aligner is determined by the thickness of the sheet. 因此,系统将通常通过改变模型牙齿的定向、模型牙齿的若干部分的大小、附件的位置和选择以及材料的添加或移除(例如添加虚拟线、添加/移除附件材料、修改一个或一个以上附件参数以及创建修改(例如补偿突起居中扭曲的修改)),来调整对准件的性能以改变对准件的结构。 Therefore, the system will typically by changing the orientation of the model teeth, several parts of the model tooth size, location, and select the attachment, and add or remove material (such as adding a virtual line, add / remove attachments material modification of one or more accessory parameters and create modifications (such as compensation projections centered modify distorted)), to adjust the performance of the aligner to change the structure of the aligner. 系统可任选地通过指定对准件中的一者或一者以上将由不同于标准厚度的厚度的薄片制成来调整对准件,以向牙齿提供或多或少的力。 The system can optionally by specifying the alignment member in one or more of the standard will be different from the thickness of the sheet is made to adjust the thickness of the alignment member, to provide more or less force to the teeth. 另一方面,如果将通过立体光刻工艺来制作对准件,那么对准件的厚度可局部改变,且可添加例如附件凹座或啮合部分、缘边、陷窝和波纹等结构特征,而不修改牙齿的数字模型。 On the other hand, if the aligner will be made by the stereolithography process, the thickness of the alignment member may be locally changed, and may be added e.g. attachment or engaging recess portion, rim, depression and other structural features and corrugated nest, and does not modify the tooth digital model. 还可使用所述系统来对例如止动件和牙箍等较传统的器具的效果进行建模,且因此使用所述系统来为特定患者产生最优设计和治疗程序。 The system may also be used to effect, for example, stoppers and braces and other more traditional modeling apparatus, and therefore the use of the system to produce the optimal design and procedure for the treatment of a particular patient.

[0111] 因此,可选择性地添加、修改/定制一个或一个以上牙齿附件,且将其包含于器具设计与制造中,其中器具和附件设计与制造以及将器具并入治疗计划中如上文所述。 [0111] Thus, selectively add, modify / customize one or more dental attachments, and be included in the design and manufacture of appliances, including appliances and accessories design and manufacturing, and will be incorporated into the treatment plan apparatus as hereinbefore said. 然而, 在一些实例中,将附件并入到器具设计中可能在器具的其它表面处导致器具的几何形状的后续改变,例如在被患者佩戴时。 However, in some instances, will be incorporated into subsequent attachment appliance design change may cause the geometry of the surface of the appliance in other appliances, for example, when worn by the patient. 此些改变或更改可导致牙齿与器具之间的接触表面的性质或位置改变,有时是以较佳地将所要力系施加到患者的牙齿的方式,且有时是以不合意的方式。 This change may cause some changes or changes in the nature or location of the contact surface between the tooth and the appliance, and sometimes is preferable to the way the force system applied to the patient's teeth, and sometimes in an undesirable way. 由此,可在附件和/或器具设计中建模或考虑改变或扭曲。 Thereby, modeling or consider changing or twisting attachment and / or appliance design. 举例来说,可依据发生的概率以及此些改变/扭曲对所要的加载和牙齿移动将是有益的还是有害的来以计算方式分析或确定改变、扭曲等。 For example, the probability of occurrence and this can be based on some changes / twisted pair to be loaded and the tooth movement would be beneficial or harmful to computationally analyze or determine changes distortions. 可包含若干方法以确定这些几何改变的效果,且通过识别新的表面或形状并加载以实现所要移动来补偿所述改变。 May contain several methods to determine these geometrical effect of the change, and by identifying new surface or shape and to achieve the load to be moved to compensate for the change. 因此可在此反复设计过程中改进器具几何形状和附件参数,因为所述过程又考虑每一特征及其对器具几何形状、对接触表面和对设计正畸系统时所产生的力系的影响。 Therefore, the appliance can be improved geometry and accessory parameters in this iterative design process, because the process and consider each feature and the geometry of the appliance, the contact surface and the impact on the design of orthodontic force system produced by the system.

[0112] 参看图15A到图15D以及图16说明根据本发明实施例的修改器具表面以补偿因将附件并入治疗计划中而导致的效应(例如,扭曲效应)。 [0112] Referring to FIGS. 15A to 15D and Figure 16 illustrates the attachment is incorporated to compensate for the resulting treatment plan in effect (for example, the distorting effects) modify the device surface in accordance with this invention. 图15A到图15B分别说明具有经定位牙科器具的初始牙齿位置以及所得的不合意力向量。 FIGS. 15A to 15B illustrate initial tooth position and the resultant undesirable force vector has positioned dental appliance. 参看所述图,在如图所示的牙齿正在沿χ方向的面部方向上移动的实例中,在将例如聚合物壳对准件等牙科器具定位于牙齿上后,对准件几何形状即刻经配置以将预定力施加于牙齿上以根据针对特定治疗阶段的治疗计划来重定位所述牙齿。 Referring to the diagram, as shown in dental facial direction is along the direction of movement χ instance, after the example of the polymeric shell aligner and other dental appliance is positioned on the teeth, immediately after the aligner geometry configured to a predetermined force is applied to the teeth for a particular treatment stages in accordance with a treatment plan to relocate the teeth. 举例来说,如图15B中所示,牙科器具经配置以配合于牙齿上以将牙齿重定位于如图所示的χ方向上,但相反地导致在如图所示且由箭头说明的+x/-z 方向上施加预定力。 For example, it is shown in FIG. 15B dental appliance is configured to fit on the teeth to the teeth on the relocation in the direction as shown χ, but conversely results in and illustrated by the arrow shown in FIG.'s + predetermined force is applied on x / -z direction. 器具可包含安置于腔中的一个或一个以上成形特征。 Disposed in the cavity means may comprise one or more shaped features.

[0113] 因此,在一个方面中,可优化对准件几何形状和/或附件参数,以补偿不合意但所得的力向量,以便抵消其力且进一步在基于针对所考虑的治疗阶段的治疗计划的方向上施加既定力。 [0113] Accordingly, in one aspect, the aligner can be optimized geometry and / or attachment parameters to compensate for undesirable but the resultant force vector in order to counteract its force and further based treatment programs for treatment stage under consideration established on the direction of the force applied. 对对准件的一个示范性修改可包含添加释放组件。 One of the aligner exemplary modification may include adding a release assembly. 图15C到图15D分别说明将释放添加到牙科器具以抵消牙齿周围不合意的力向量,以及牙科器具对牙齿上的预定力的所得所要施加。 FIG. 15C to FIG. 15D illustrate the release added to the dental appliance around the teeth to offset the undesirable force vector, and the resulting dental appliance to a predetermined force on the tooth to be applied. 在一个方面中,为了补偿不合意的力(例如,如图15B中由箭头所示),可提供预定释放(例如,但不限于0. Imm到0. 3mm),使得对准件与牙齿之间导致不合意的力向量的接触得以避免,但仍(例如)沿如上文所论述的χ轴保持所要的力。 In one aspect, in order to compensate for the undesirable force (for example, as shown by the arrows in FIG. 15B), can provide a predetermined release (such as, but not limited to 0. Imm to 0. 3mm), so that the teeth of the aligner result in contact between undesirable force vector is avoided, but still (for example) as discussed above along the χ axis to maintain the desired force.

[0114] 参看图15C,对准件上的预定释放由箭头说明,借此通过修改对准件几何的形状来去除对准件与牙齿之间在导致不合意的力的位置处的啮合。 [0114] Referring to FIG. 15C, predetermined release by the arrow on the aligner described, whereby by modifying the shape of the aligner geometry to remove the engagement between the alignment member and the teeth lead to undesirable forces position. 以此方式,在一个方面中,且如图15D中所示,通过(例如)修改对准件几何形状来实现(例如)在χ方向上施加于牙齿 In this manner, in one aspect, and as shown in FIG. 15D, by (e.g.) modified geometry to achieve the alignment member (e.g.) in the χ direction is applied to the teeth

19上的既定和合意的力。 Established and desirable force on 19.

[0115] 图16说明经修改的牙科器具几何形状,其包含额外的形状修改以去除牙科器具与牙齿之间的间隙。 [0115] FIG. 16 illustrates a modified dental appliance geometry, which contains additional shape modification to remove the gap between the teeth and the dental appliance. 参看图16,将注意到,虽然对准件几何形状的修改(例如,上文结合图15C到图15D所论述)使得所要的预定力按照牙科治疗所计划而施加于牙齿上,但牙齿与对准件之间(例如如图16所示)在牙龈区域附近可能形成间隙或凹穴。 Referring to FIG. 16, it will be noted, although the aligner geometry modifications (such as described above with respect to FIG. 15C, 15D discussed) makes the desired predetermined force in accordance with the planned dental treatment is applied to the teeth, but teeth and for between prospective members (such as shown in FIG. 16) may be gaps or pockets in the gums near the area. 在一个方面中,为了考虑所产生的此间隙或凹穴,可进一步修改或优化对准件几何形状,(例如)以在对准件处于作用(或拉伸)状态时在朝向牙齿的方向上更好地适应。 In the direction toward in one aspect, in order to consider this gap or pocket generated, can be further modified or optimized aligner geometry, (for example) to the alignment member is in effect (or stretching) the state of the teeth better adapt.

[0116] 参看图16,在一个实施例中在可修改对准件形状的方向上通过箭头说明优化对准件几何形状以解决所形成的间隙或凹穴。 [0116] Referring to FIG. 16, in one embodiment, can be modified in the direction of the arrow aligner shape description aligner geometry optimization to address gaps or pockets formed. 此外,应注意,优化对准件形状以考虑间隙可能潜在地影响对准件对牙齿施加的力的方向,且因此可能进一步需要额外的修改或优化。 Furthermore, it should be noted that in order to optimize the aligner shape considering a gap that could potentially affect the direction of the aligner force exerted on the teeth, and therefore may require additional modifications or further optimization.

[0117] 在一个方面中,修改附件参数和/或牙科对准件几何形状(例如具有一个或一个以上修改区域(例如释放等)),以及为较松或较紧的适应而重新定轮廓以实现所要的力向量,同时避免摩擦和其它不合意的力向量,这将为牙齿病情的治疗提供改进的且定制的对准件形状。 [0117] In one aspect, amend Annex parameters and / or dental aligner geometry (such as having one or more modifications region (such as the release, etc.)), as well as loose or tight to adapt and re-contoured to achieve the desired force vector, while avoiding friction and other undesirable force vector, which will provide improved treatment of dental disease and are customized aligner shape. 在制造牙科器具时,在一个方面中,可在建立过程期间调整模具,以基于(例如) 在模具的预界定或相关位置中数字地添加和/或减去释放和/或附件接触/啮合部分而获得所要几何的形状。 In the manufacture of dental appliances, in one aspect, the mold can be adjusted during the setup procedure, based on (for example) in a pre-defined position in the mold or the relevant figures add and / or subtract release and / or accessory contact / engagement portion and obtain the desired geometric shape.

[0118] 在一个方面中,基于根据材料性质和垂直于由针对特定治疗阶段的移动向量而产生的复合向量的表面积的量而确定的力行为,可通过使用可针对所要移动而选择且进一步定制的附件来将额外的表面积添加到牙齿。 [0118] In one aspect, based on based on the material properties and the force acts perpendicularly to the amount of surface area for a motion vector of a particular treatment stage to produce a composite vector determined, can be for a desired movement is selected by use and further customization attachment to add additional surface area to the teeth. 以此方式,在一个方面中,可为特定牙齿确定表面区域的横截面和/或定向,且可将附件并入一个或一个以上牙齿上,以增强或改进必要的表面积,以与牙科器具协作或啮合以在针对治疗阶段的准确方向上在牙齿上实现所要的移动向量或预定等级的力。 In this manner, in one aspect, the teeth may be determined for a particular cross-sectional surface area and / or orientation, and may be incorporated in one or more attachments to the teeth, in order to enhance or improve the necessary surface area, in collaboration with the dental appliance or engaging in the exact direction for treatment stage on the tooth to achieve the desired motion vector or a predetermined level of force.

[0119] 以此方式,且如本文进一步陈述,可使用计算机辅助的设计工具或系统来设计、制造或模拟牙科对准件和/或附件,其中首先对待移动的牙齿的表示进行建模。 [0119] In this way, and as described further stated, use of computer-aided design tool or system to design, manufacture or analog dental aligner and / or accessories, which first expressed treat tooth movement modeling. 其后,以所界定的几何形状性质来对界定牙齿的目标位置的对准件进行建模。 Thereafter, the geometric shape defined by the nature of the alignment member to define the position of the target tooth modeling. 其后,(例如)使用FEA建模或其它合适的计算和/或建模技术来确定将牙齿从初始位置重定位到目标位置所必需的力或对所述力进行建模。 Thereafter, (for example) using FEA modeling or other suitable computing and / or modeling techniques to determine the tooth from the initial position to the target position relocation necessary force or the force to be modeled. 在一个方面中,有可能使用连接到力测量传感器的牙齿的物理模型来界定力,使得可使用从物理模型获得的读数来确定最佳力,且因此至少部分地基于来自物理测力计的反馈而更改一个或一个以上附件参数和对准件配置。 In one aspect, it is possible to use the force measuring sensor is connected to the physical model of the teeth to define the force, making it possible to use the readings obtained from the physical model to determine the optimal power, and therefore, at least in part, based on feedback from the physical dynamometer to change one or more attachments and aligner configuration parameters.

[0120] 因此,界定移动向量,其建立所施加力的方向,以及力的等级及其性质,其是将牙齿从初始位置重定位到目标位置所必要的。 [0120] Thus, defining the motion vector, to establish the level and nature of the direction of the applied force, and the force, which is the tooth from the initial position to the target position relocation necessary. 基于移动向量以及经建模的对准件和/或附件,进一步修改或重新配置对准件和/或附件以将预定移动向量计算在内。 Based on the motion vector and by modeling aligner and / or accessories, to further modify or reconfigure the alignment member and / or attachment to a predetermined motion vector calculation. 即,在已界定识别牙齿重定位所必要的力性质的移动向量之后,基于所确定的移动向量而更改或优化牙科器具形状和/或附件参数。 That is, after the teeth have been defined to identify the necessary relocation of the motion vector force in nature, based on the determined motion vector to change or refine the shape of the dental appliance and / or accessories parameters. 另外,可进一步基于所界定的移动向量而优化器具形状和/或附件参数以抵消不合意的力或力分量,或可能导致的器具扭曲(例如,因附件的缘故)。 In addition, based on the motion vector may be further defined and optimized appliance shape and / or attachment parameters to counteract undesirable force or force component, or may cause the appliance distortions (for example, Annex sake).

[0121] 其后,可通过快速原型设计(例如立体光刻)或其它合适的技术来制造经修改或经优化的牙科器具,以实现所要的牙齿移动。 [0121] Thereafter, as amended, may be manufactured or optimized by rapid prototyping dental appliance (eg stereolithography) or other appropriate techniques to achieve the desired tooth movement. 另外,可重复此过程,以针对治疗计划的每一治疗阶段而优化牙科器具,使得对准件性能且因此治疗计划结果得以改进。 In addition, you can repeat this process to each treatment phase treatment plan that is optimized for the dental appliance, making the aligner treatment program performance and therefore the results can be improved.

[0122] 此外,在再一方面中,可基于垂直于牙齿移动的所要方向的最大量的可用表面区 [0122] In addition, in another aspect, can be based on tooth movement perpendicular to the direction you want the maximum amount of the available surface area

20域的位置而确定附件设计和/或放置。 Location 20 domain determining accessory has been designed and / or placement. 另外,如果治疗计划中的任何给定牙齿上的力处于或低于预界定等级,那么可将附件添加到牙齿或器具以补充所要的表面积,或增加牙齿的摩擦系数,从而改进对准件在牙齿上的力分布。 In addition, if the treatment plan in force at any given teeth at or below a pre-defined rating, then you can add attachments to teeth or appliance to complement the desired surface area, or increase the coefficient of friction of the teeth in order to improve the alignment member force distribution on the teeth.

[0123] 在一个方面中,可通过(例如)添加、部分或全部减去、均勻或非均勻缩放、布尔(Boolean)或非布尔算法,或几何运算,或其一个或一个以上组合来有意地更改与牙齿、牙龈和/或其它口腔组织或结构相关联的数据集,以配置、建模和/或制造可针对所要或既定治疗目标而优化的牙科器具。 [0123] In one aspect, by (for example) to add, subtract some or all of uniform or non-uniform scaling, boolean (Boolean) or Boolean arithmetic or geometric operations, or a combination of one or more intentionally Changes to the teeth, gums and / or other oral tissues or structures associated with the data set to configure, model, and / or manufacturing may be directed to be optimized treatment goals or dental appliance.

[0124] 此外,进一步就本文关于附件设计和定制的论述而论,可选择或提供角度形成或附件以及附件的表面配置,以改进移动向量以优化其对所要牙齿的施加,同时使不合意或有害的力向量(例如可抵消移动向量的向量)的量减到最小。 [0124] In addition, further to this article on attachment design and customization of discourse is concerned, choose or to provide an angle formed or disposed on the surface of accessories and attachments, to improve the motion vectors to be applied to the optimization of their teeth, while undesirable or harmful force vector (e.g., motion vectors may be offset vector) minimizes the amount. 另外,在一个方面中,可提供多个附件(例如一系列邻接附件),以更改力方向或产生持续预定时间周期的移动向量,使得所述系列的邻接附件可经配置以充当缓慢运动凸轮,其中牙科器具接着充当随动件。 Additionally, in one aspect, it provides multiple attachments (such as a series of adjacent annex), to change the direction of the force or generating a predetermined time period of the motion vector, so that the adjacent annex of the series can be configured to act as a slow movement of the cam, dental appliance which then acts as a follower.

[0125] 在又一方面中,可添加点跟踪以在治疗阶段中处理且/或跟踪牙齿点,使得可确定所要或合适的凸轮/随动件关系,以实现目标位置或治疗目标。 [0125] In yet another aspect, you can add points to handle tracking and / or tracking teeth point in the treatment of stage, making it possible to determine a desired or appropriate cam / follower relationship, in order to achieve the target location or therapeutic target. 在一个方面中,可将牙科器具的内表面上的一个或一个以上突起配置为随动件,且其可由虚拟压力点形成。 In one aspect, one or more may be on the inner surface of the dental appliance is configured as a follower projection and virtual pressure points which can be formed. 在一个实施例中,虚拟压力点由有意建立或设计到参考模具或模型中的空隙组成,所述参考模具或模型与当对准件形成于参考模具上时对准件中既定将额外压力施加于牙齿上的对应部分相关联。 In one embodiment, the virtual pressure points set up by the intentional or designed to reference the mold or model voids composition of the reference model and the mold or when the aligner is formed on the reference mold member when the alignment established additional pressure is applied in the corresponding portion of the associated teeth.

[0126] 因此,在一个方面中,首先确定n+1或后续/目标牙齿位置。 [0126] Accordingly, in one aspect, first determine n + 1 or later / target tooth position. 其后,确定从初始牙齿位置到达目标牙齿位置的移动方向。 Thereafter, it is determined to reach the moving direction of the target position of the teeth from the initial tooth position. 在确定移动方向之后,确定将牙齿从初始位置重定位到目标位置的力和力矩的量或量值和方向。 After determining the direction of movement from the initial position to determine the tooth relocated to the amount or magnitude and direction of the target position of power and torque. 其后,确定将在所计划的牙齿移动的方向上提供最合适的啮合、夹持和/或负载向量的附件的轮廓,包含(例如)与牙齿表面有关的附件的几何形状、位置等。 Thereafter, it is determined to provide the most appropriate engagement in the direction of the planned tooth movement, outline attachment clamp and / or load vectors containing (for example) related to the geometry of the tooth surface attachment, location.

[0127] 在已确定附件的相关轮廓/参数后,可确定附件位移以实现从初始位置到目标位置的位置平移。 [0127] After having identified the relevant Annex profile / parameters can be determined in order to achieve the position of translational displacement attachment from an initial position to the target position. 在将附件定位于牙齿上后,后续治疗阶段的牙科器具即刻经由经定位的附件而与牙科器具的牙齿触点啮合。 After the attachment is positioned on the teeth, the subsequent treatment stages via dental appliance immediately after positioning and attachment of the tooth and a dental appliance engaging the contacts. 以此方式,在所要方向上准确地引导牙科器具在由患者佩戴时所产生的力/力矩,且还以足够的量值配置所述力/力矩以按既定方式移动牙齿,例如移动到下一所计划位置中。 In this manner, in the desired direction accurately guiding force when the dental appliance worn by the patient produced / torque, and also configured with sufficient magnitude the force / moment to move in a predetermined manner of teeth, for example, move to the next The planned position. 举例来说,在一个实施例中,将附件接合到患者的牙齿。 For example, in one embodiment, the attachment is bonded to the patient's 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. 经移位或重定位的附件可离开与牙科器具上的附件的形状一致的腔的新位置。 After attachment displaced or relocated to a new location and leave the same shape of the cavity attachment on the dental appliance. 在附件在初始阶段位于牙冠上且在后续目标治疗阶段移位的情况下,目标治疗阶段的牙科器具可能在初始治疗阶段干扰牙齿上的附件。 And in the case of a subsequent treatment stage shift target, target treatment stage dental appliance may interfere with the attachment of the tooth in the initial treatment phase in the initial stage of attachment located on the crown. 所述干扰又经配置以产生力/力矩以形成所要的牙齿移动。 The interference and is configured to generate a force / torque to form the desired tooth movement.

[0128] 在一个方面中,可通过(例如)调整附件的轮廓、参数和/或相对于牙冠表面的定位来修改或优化力/力矩的方向和量值,以产生抗衡力/力矩以消除或最小化有害翻转力矩、实现牙根移动等。 [0128] In one aspect, by (for example) to adjust the attachment profile, parameters and / or relative to the crown surface positioned to modify or optimize the force / torque direction and magnitude, to produce a counter force / torque to eliminate or minimize the harmful overturning moment, to achieve root movement. 相对于牙冠的附件移动的量还可与牙齿移动相关,以基于特征在牙齿上的移动而产生治疗计划。 Annex crown relative to the amount of movement can also be associated with the tooth movement, in moving the teeth to produce a treatment plan based on the feature.

[0131] 图18是说明附件参数确定(包含附件轮廓和定位)的流程图。 [0131] FIG. 18 is a flowchart illustrating attachment parameter determination (including the attachment profile and positioning). 参看图18,确定第一治疗阶段时的牙齿位置(步骤2210)。 Referring to Figure 18, to determine the position of the teeth of the first treatment stage (step 2210). 确定第二或n+1治疗阶段时的牙齿位置(步骤2220)。 Determining a second position of the teeth or n + 1 treatment stage (step 2220). 其后,确定与从第一治疗阶段到第二治疗阶段的牙齿移动相关联的移动向量(步骤2230)。 Thereafter, it is determined from the first treatment stage to the second phase of treatment tooth movement associated with the motion vector (step 2230). 在确定与牙齿移动相关联的移动向量之后,确定与移动向量相关联的一个或一个以上附件/附件轮廓(步骤2240)。 In determining tooth movement associated with the motion vector determined after accessory / attachment profile and a motion vector associated with one or more (step 2240). 确定附件参数,例如牙科附件的位置、牙科附件的角度形成、垂直于来自牙科器具的力的方向的表面积。 OK attachment parameters, such as the angular position of dental accessories dental attachments formed perpendicular to the direction of the force from the surface area of the dental appliance. 其后,在治疗阶段期间将一个或一个以上附件定位于牙齿上以与对应的器具接触(步骤2250)。 Subsequently, during the treatment phase one or more accessory positioned on the teeth to contact the corresponding apparatus (step 2250). 可如本文进一步所述定制和选择附件参数轮廓和定位,以实现所要的牙齿移动(例如见图3)。 As further described herein can customize and select the attachment parameter profile and positioning to achieve the desired tooth movement (for example, see Figure 3). 以此方式,在一个实施例中,将来自牙科器具的力/力矩准确地施加到牙齿,以将牙齿从初始位置重定位到目标或第二治疗阶段位置。 In this manner, in one embodiment, the force from the dental appliance / torque is applied to the tooth accurately, to relocate the tooth from the initial position to the target position or the second treatment stage.

[0132] 如上文所述,本发明的实施例提供由若干参数控制的附件,使得附件的形状和附件在牙齿上的位置是患者特定的,且提供最优的力和力矩。 [0132] As described above, embodiments of the present invention provide several parameters controlled by the attachment so that the shape and location of accessory attachment on the tooth is patient specific and provide optimal power and torque. 明确地说,确定参数化患者特定附件的形状和位置,使得满足以下条件:1)围绕牙齿的长轴提供具有临床上容许量值的力矩;2)提供临床上合理的挤压力;以及幻排除了在牙齿移动的中间阶段附件与(同一颚和相对颚的)其它牙齿的碰撞。 Specifically, determine the parameters of the shape and position of the patient-specific attachments, so as to satisfy the following conditions: 1) around the long axis of the teeth to provide torque values have allowed clinical; 2) to provide clinically reasonable extrusion pressure; and Magic excluding the impact intermediate stages of tooth movement and attachments (the same jaw and opposite jaw) other teeth. 可根据正畸学文献、专家意见、临床经验和组织阻力的计算机模拟结果来确定力和力矩的容许量值。 Forces and moments can be determined based on the allowable values orthodontic literature, expert opinion, computer simulation results of clinical experience and organizational resistance.

[0133] 图19说明可通过沿与对象的旋转轨迹正切的任何方向施加力来移动对象。 [0133] FIG. 19 illustrates in any direction by rotating the tangent track along with the object of applying a force to move objects. 具体地说,施加到对象2300的力(a、b、c或d)可通过臂(r)与施加到对象的力的量(F)的交叉乘积(rxF)的力矩来在圆上使对象旋转。 Force can be applied to a particular object, the object Force 2300 (a, b, c or d) is applied to the arm (r) of the amount (F) of the cross product (rxF) torque to make an object on a circle rotation. 一对相等且相反的力可产生具有零所得力(例如,力a与c或力b与d)的力矩。 A pair of equal and opposite forces may have a zero resultant force generation torque (e.g., a force or force with c and b d) is. 三个参数一起产生一力矩:1)力向量,2)施力点,和3) 测量力矩的点。 Three parameters together produce a moment: 1) force vector, 2) the point of application, and 3) measuring the torque point. 施力点和测量力矩的点决定臂向量。 Force application point and measuring the torque arm vector points decision. 当使牙齿旋转时,相对于牙齿的阻力中心而计算力矩。 When the tooth is rotated, with respect to the teeth of resistance center calculated torque.

[0134] 牙齿旋转的先前实践是将标准附件添加到牙冠的中心,或牙齿的颊面的面部轴线点,且规划牙齿的旋转。 [0134] The previous practice of tooth rotation is to add a standard accessory to the center of the crown, or facial axis point buccal surface of the teeth, and the teeth of the rotation plan. 使用热成形工艺,在标准附件的形状上以热塑性薄片形成对准件中的附件接纳井。 Use thermoforming process, in the shape of a standard accessory to the thermoplastic sheet forming the alignment member attachment receiving well. 所得附件接纳井在某些区域中接触所接合的附件,从而在患者佩戴对准件时产生使牙齿旋转的力分布。 The resulting attachment receiving well contacts engaged by attachment in some areas, resulting in the rotation of the force distribution of the teeth when the patient wearing the aligner. 然而,此常规旋转方法无法一致地控制接触和所得力分布。 However, this conventional rotary method can not consistently controlling the contact force and income distribution.

[0135] 在一个方面中,为了解决常规标准附件的缺点,本发明提供对准件激励件。 [0135] In one aspect, in order to solve the drawbacks of the conventional standard accessories, the present invention provides an alignment member activator. 标准附件方法与本发明的对准件激励件之间的主要差异在于产生附件主体与附件接纳井之间的接触点。 Standard accessories method of the present invention aligner member main difference between the incentive is to generate attachment body and the attachment receiving point of contact between the wells. 如本文所使用,激励件可包含对准件或正畸系统的啮合附件的作用表面以便将负载施加到牙齿的任何特征。 As used herein, the activator may comprise engaging the alignment member or orthodontic attachment system so that the active surface of the load applied to the teeth of any of the features. 可利用多种激励件结构,其中非限制实例包含附件接纳井或其 It offers a variety of incentive-piece structure, wherein the non-limiting examples thereof that contains an attachment receiving well

22表面、陷窝、隆脊、放置于对准件与附件之间的主体(例如复合物)等。 22 surface, dimples, ridges, placed in the body (such as composites), etc. between the alignment member and accessories. 在标准附件中,接触点由附件主体与附件接纳井的因牙冠从初始阶段到后续阶段的旋转而导致的位置偏差界定。 In the standard accessories, the contact point is received by the body and the accessory attachment well positional deviation due to the rotation from the initial stage to crown a subsequent stage which led to the definition. 在此情况下,通过热成形工艺来使附件主体的形状与附件接纳井的内表面一致。 In this case, by thermoforming processes to make the shape of the accessory attachment body inner surface of the well accepted unanimously. 根据本发明的实施例,附件主体与附件接纳井的位置偏差仍存在。 According to an embodiment of the present invention, the attachment body and the attachment receiving well positional deviation still exists. 另外,不同地设计附件主体和附件接纳井的形状,使得附件接纳井接触并施加临床上所要的力和力矩,而无上文所提到的偏差。 In addition, different design accessory body shape and attachment receiving well, making contact with the attachment receiving well and clinically applied forces and moments to be without bias mentioned above. 在此情况下,附件/激励件对是在无任何牙冠移动的情况下产生牙齿移动所要的力分布。 In this case, the attachment / activator pair is to produce tooth movement desired force distribution in the absence of any movement of the crown. 根据本发明的实施例,附件/激励件对是用于沿牙齿的长轴的上部和下部牙齿旋转。 According to an embodiment of the present invention, the attachment / activator pair is used for the upper and lower teeth, teeth along the long axis of rotation. 然而,如所属领域的技术人员将了解,可使用附件/激励件对来促进其它正畸移动。 However, as those skilled in the art will appreciate that the use of attachment / activator pair to promote other orthodontic movement.

[0136] 使用对应于不同参数的参数设计工具来设计附件/激励件对。 [0136] The parameters corresponding to the different parameters of design tools to design attachment / activator pair. 在以下表1中列出了参数,以及所述参数的对应功能和识别符号。 It lists the parameters, and the corresponding function and identification code of the parameter in Table 1 below. 将具有配置于对准件中的激励件的参数旋转附件缩写为PRAA。 You will have to configure the parameters of the alignment member rotating attachment activator abbreviated as PRAA. 根据本发明的实施例,可确定参数的优先级或将优先级指派给参数。 According to an embodiment of the present invention can determine the priority or the priority assigned to the parameter parameter. 举例来说,可向碰撞指派较高优先级或用较高优先级来加权碰撞,使得在设计和/或定位将导致碰撞事件的情况下,可拒绝对提供良好力施加的附件的识别。 For example, you can assign a higher priority or with higher priority to the weighted collision to collision, so in the case of the design and / or positioning will result in a collision event, refuse to recognize the force applied to provide good attachment.

[0139] 图20说明上面形成有牙齿附件MlO的牙齿M00。 [0139] FIG. 20 illustrates formed above tooth attachments MlO teeth M00. 该图展示相对于牙齿MOO的X轴、y轴和Z轴,以及相对于牙齿附件MlO的PRAAx轴、PRAAy轴和PRAAz轴。 The figure shows the relative MOO dental X-axis, y-axis and Z-axis, as well as with respect to the tooth attachments MlO of PRAAx axis, PRAAy axis and PRAAz axis. 该图另外展示针对牙齿附件MlO的y轴原点(Oy)和ζ轴原点⑴ζ)。 The figure for the y-axis shows the origin of additional tooth attachments MlO the (Oy) and ζ axis origin ⑴ζ).

[0140] PRAA的y轴的原点(Oy)是沿牙冠的高度的PRAA原点的位置,其可能影响力输出。 Origin of the y-axis [0140] PRAA the (Oy) is the height of the position of crown PRAA origin, which may influence the output. 所述力可能因对准件厚度且因此强度沿牙冠的高度改变而受影响。 The force may vary depending on the thickness of the alignment and thus change the intensity along the height of the crown affected. 通过降低PRAA的y轴的原点,牙齿附件MlO更靠近其中对准件材料较薄且柔性较大的牙龈线。 Lowering through the origin of the y-axis PRAA, tooth attachments MlO wherein the alignment member is closer to the flexible material is thinner and larger gum line.

[0141] PRAA的ζ轴的原点(Oz)是界定为施力点到牙齿MOO的纵轴之间的距离的臂长。 [0141] origin PRAA the ζ axis (Oz) is defined arm length distance of the point of application to the teeth between the longitudinal axis of MOO. PRAA的ζ轴的原点决定斜面距牙齿MOO的ζ轴有多远。 The ζ axis origin PRAA decision ramp from dental MOO's how far ζ axis. 因此,此参数控制力矩的臂长。 Therefore, this parameter controls the torque arm length.

[0142] PRAA斜坡与牙齿的xy平面之间的角度界定夹持平面相对于牙齿的xy平面相对于牙齿的纵轴的法线。 [0142] the angle between the ramp and the tooth PRAA xy plane relative to the plane defining clamping teeth xy plane normal to the longitudinal axis of the tooth. 举例来说,夹持平面表面的法线与牙齿MOO的纵轴之间的角度可为77度。 For example, the angle of the clip plane normal to the surface between the longitudinal axis of the tooth MOO may be 77 degrees. 如果力向量(F)以77度角作用于牙齿MOO上,那么可将力向量建模为F*cos (77) 的挤压力和F*sin(77)的舌向力。 If the force vector (F) to 77 degrees angle effect on teeth MOO, it can be modeled as a force vector F * cos (77) and the pressing force F * sin (77) of the tongue to force. 舌向力围绕牙齿基础的纵轴产生力矩,且挤压力防止由非所要接触导致的任何侵入趋势。 Tongue around the base of the longitudinal axis of the teeth to force generation torque, and the pressing force to prevent any intrusion tendency to be contacted by a non-result.

[0143] PRAA夹持平面与牙齿MOO的x_z平面之间的角度控制夹持平面的法线相对于牙 [0143] the angle between the plane and the tooth holder PRAA MOO's x_z control plane normal to the plane relative to the gripping teeth

23齿MOO的xz平面的定向。 MOO directed teeth 23 of xz plane. 在一个实施例中,此角度可为180°,以此角度,夹持平面法线平行于xz平面。 In one embodiment, this angle may be 180 °, this angle, parallel to the clamping plane normal to the xz plane. 在另一实施例中,此角度可为60°。 In another embodiment, this angle may be 60 °. 通过控制此角度的值,可基于附件2410在牙齿表面上的位置而最大化臂长。 By controlling the value of this angle it may be based on Annex 2410 position on the tooth surface while maximizing the arm length.

[0144] 突出参数应具有足以使牙冠表面上的所设计夹持平面暴露且同时仍无任何搭接困难地配合牙齿的值。 [0144] highlighted parameters should have enough to make the design of the crown surface of the holder plane exposed and at the same time still have no difficulty with overlapping values teeth. 如果突出值过低,那么力可能受损,因为接触可能因附件主体和附件接纳井中的夹持平面表面上的面积和界定的损失而不准确。 If the outstanding value is too low, then the force may be damaged, since the contact body and the accessory attachments may be due on the receiving area of the surface of the well and the clip plane without an accurate definition of loss. 夹持平面表面上的此面积和界定的损失可能由材料的可成形性和制造容差导致。 This area on the surface of the clamping plane and losses may be defined by the material formability and manufacturing tolerances result.

[0145] 激励件可具有相对于附件的y轴到达夹持平面表面中的角度变化。 Y-axis [0145] encourage member may have with respect to the attachment surface to reach the clipping plane angular variation. 此角度变化(称为激励角度)引起激励件与附件的夹持平面表面之间的接触。 This angle change (known as the excitation angle) cause contact with the clip plane surface activator between attachments. 激励角度可通过激励件与附件的夹持平面表面之间的所得干扰来控制力量值。 Excitation angle can be controlled by the value of the resulting interference excitation force member and the clamping surface of the attachment between the plane. 如上文所提到,激励件产生舌向力和挤压力,其趋向于以相对于激励角度为正的关系而改变。 As mentioned above, the excitation lingual force generating member and the pressing force, which tends to encourage the angle with respect to the relationship between the change is positive.

[0146] 呈弯曲主体的形式的铰链允许在夹持平面表面上激励,而不会引入与附件的其它部分的非所要接触。 [0146] in the form of bending of the body of the hinge allows the planar surface excitation on the holding, without introducing the part to be in contact with other non-attachment. 在一个实施例中,铰链在附件和附件接纳井中为由其原点和半径界定的球体。 In one embodiment, the hinge attachment and the attachment receiving well as its origin and the radius defined sphere. 在另一实施例中,铰链在附件中为由其原点和两个轴界定的椭圆体,且在附件接纳井中为球体。 In another embodiment, the hinge in the annex to its origin and the two axes of the ellipsoid defined and well accepted in the annex to the ball. 在铰链为球体的情况下,附件的原点也是球体的原点,且附件的y轴延伸穿过球体直径。 In the case of the hinge of a sphere, the sphere is the origin of the annex origin and y-axis extending through the attachment spherical diameter. 因此,沿附件的y轴的激励角度并不引入球体上的变化,且因此并不引入不想要的接触。 Thus, along the y-axis excitation angle attachment does not introduce changes in the sphere, and therefore does not introduce unwanted contacts. 在铰链为椭圆体的情况下,附件的原点也是椭圆体的原点,附件的y轴延伸穿过椭圆体的一个轴,且椭圆体的另一轴比附件接纳井中的球体直径短。 In the case of the hinge of the ellipsoid, y axis origin attachment is the origin of the ellipsoid, the attachment of a shaft extending through the oval body, and shorter than the diameter of a sphere attachment receiving well is another axis of the ellipsoid. 因此,沿附件的y轴的激励角度不引入椭圆体上的接触。 Thus, along the y-axis excitation angle attachment without introducing contacts ellipsoid.

[0147] 在给定铰链半径的情况下,夹持平面的高度界定PRAA相对于其自己的坐标系和原点的夹持平面。 [0147] In the case of a given radius of the hinge, the clip plane defined PRAA height relative to its own coordinate system and the origin of the clip plane. 不管夹持平面的角度如何,夹持平面表面与牙齿的χ-y平面之间的角度可适于产生挤压分量。 Regardless of how the angle of the clip plane, the angle between the plane surface of the clamping teeth χ-y plane may be adapted to produce extruded components. 然而,然而,如果夹持平面的高度过小,且夹持平面的角度过大,那么将不良地形成PRAA的夹持平面。 However, however, if the height of the clip plane is too small, and the angle of the clip plane is too large, then the clamping plane formed PRAA undesirably. 根据本发明的实施例,夹持平面的高度不应小于3mm。 According to an embodiment of the present invention, the height of the clip plane should not be less than 3mm.

[0150] 使用以下参数来控制附件在牙齿上以及激励件在对准件上的定位:1)PRAA的原点ζ (Oz),其为从附件的原点到临床牙冠中轴(FACC)咬合点的距离;2)PRAA的y轴的原点(Oy),其对应于臂长;3)附件的夹持平面与牙齿的χ-y平面之间的角度(见表1中的参数P3) ;4)附件的突出(见表1中的参数P4) ;5)激励角度(见表1中的参数P6),其为激励件的夹持平面与附件的夹持平面之间的角度;6)从附件到牙龈曲线的最小距离;以及7)牙齿的牙间裕量。 [0150] and locate the following parameters to control the excitation member attachment to the teeth on the aligner: 1) PRAA origin ζ (Oz), which is from the origin to the clinical crown attachment axis (FACC) nip point distance; y-axis origin 2) PRAA the (Oy), which corresponds to the arm length; 3) the angle between the clamping plane χ-y plane of the tooth attachment (see Table 1 Parameter P3); 4 ) to highlight the annex (see Table 1 in the parameter P4); 5) excitation angle (see Table 1 in the parameter P6), which is sandwiched between the clip plane plane parts and accessories excitation angle; 6) from and 7) margin between teeth teeth; minimum distance curve annex to the gums.

24[0151] 图M是说明用于提供患者特定附件且用于将附件定位于患者的牙齿上的方法的流程图。 24 [0151] M is an explanatory diagram for providing patient specific attachment and the attachment is positioned on the flow chart of a patient method for teeth. 所述方法通过识别需要附件的牙齿(步骤2700)而开始。 The method by identifying needs dental attachments (Step 2700) and start. 为了确定牙齿是否需要附件,或牙齿在哪一阶段间隔中需要附件,执行算法以计算总旋转移动。 In order to determine whether dental attachments, or at what stage tooth interval required attachment, execution of the algorithm to calculate the total rotational movement. 如果移动多于指定阈值,那么将牙齿识别为需要附件。 If you move more than a specified threshold value, then the tooth is identified as required attachments.

[0152] 检测用于定位附件的任何约束(步骤2705)。 Any constraints (step 2705) [0152] Detection for positioning the attachment. 下文参看图25来描述定位约束。 FIG. 25 is described below with reference positioning constraints. 接着设置附件的当前位置,使得附件定位于所约束的边界内(步骤2710)。 Then set the current position of the annex, so that attachment located within the boundary of the constraint (step 2710).

[0153] 接着作出附件的当前位置是否在规则臂区中的确定(步骤2715)。 [0153] then made to determine whether the current position of the attachment arm area in the rule (step 2715). 如果附件的当前位置在规则臂区中,那么处理进行到步骤2720,其中发生规则附件/激励件对的初始建模。 If the current position of the attachment arm area in the rule, then the process proceeds to step 2720, which took the initial ModellingRule Accessories / activator pair. 如果附件的当前位置不在规则臂区中,那么处理进行到步骤2725,其中发生短臂附件/ 激励件对的初始建模。 If the current position is not in the rules of the attachment arm area, the process proceeds to step 2725, which took the initial modeling of the short arm attachment / activator pair. 附件/激励件对是患者特定且牙齿特定的。 Accessories / activator pair is patient specific and tooth-specific. 附件/激励件对的形状和位置由牙齿的几何形状决定。 The shape and location of attachment / activator pair is determined by the geometry of the tooth. 举例来说,当牙齿较大时,可能需要较大的附件。 For example, when the tooth is large, you may need a larger attachments. 使用形状参数来对附件/激励件对的初始形状进行建模,其可在必要时修改。 Using a shape parameter to model the initial shape attachment / activator pair, which can be modified if necessary. 接着将附件定位于牙齿上(步骤2730)。 Next, the attachment located in the tooth (step 2730).

[0154] 基于附件的初始形状和位置来计算附件参数(步骤273¾。实例附件参数包含臂向量、臂长、夹持平面面积、夹持平面宽度以及夹持平面长度。如果参数值中的任一者不属于预定值范围内,那么修改附件的形状(步骤2740)。如果所有参数值均在可接受范围内, 那么附件的形状和位置不需要修改。 [0154] Based on the initial shape and position of the accessory attachment parameters calculated (step 273¾. Examples arm attachment parameter vector comprises, arm length, clamping plane area, clamping plane width and length of the clipping plane. If any of the parameter values of a do not fall within a predetermined value, then modify the shape of the attachment (step 2740). If all parameters are within acceptable limits, then the shape and position of the attachment without modification.

[0155] 检查碰撞和约束(步骤2745)。 [0155] to check collisions and constraints (step 2745). 附件不应与其它对象(例如其它牙齿或附件、隆脊、虚拟填充物等)碰撞。 Accessories should not other objects (such as other dental accessories, ridges, dummy fill, etc.) collisions. 另外,应满足约束阈值,例如距牙龈曲线的距离、距牙间区或区域(IP区或IPR)的距离、距切缘的距离等。 Additionally, it should satisfy the constraint threshold, such as the distance from the gingival curve, the distance from the interdental area or region (IP zone or IPR), the distance from the cutting edge and the like.

[0156] 接着作出附件是否提供将导致牙齿的所要移动的解决方案的确定。 [0156] Next to the attachment is provided will lead to the identification of the teeth to be moved solutions. 如果附件未提供所要解决方案,那么处理返回到步骤2710,其中修改附件的位置。 If the attachment does not provide the desired solution, the process returns to step 2710, which modify the position of the attachment. 如果附件提供将导致牙齿的所要移动的解决方案,那么处理移动到步骤2755,其中将所述解决方案应用于对患者的治疗。 If the accessory will cause the teeth to be mobile solutions, the process moves to step 2755, wherein the solution used in the treatment of patients. 接着,处理终止。 Then, the processing is terminated.

[0157] 图25说明在确定附件在牙齿上的位置时应满足的定位约束。 [0157] FIG. 25 illustrates the determined attachment position on the teeth should be positioned to meet the constraints. 当确定附件位置时, 考虑以下参数:1)牙龈线;2) IP区(在牙齿的面部侧);3)从远端点/中间端点开始的牙间边界;4)中间平面(xz平面);以及5)牙齿切缘约束。 When determining the attachment position, consider the following parameters: 1) the gum line; 2) IP zone (in the teeth of the face side); 3) the boundary between the teeth from the distal end point / intermediate endpoint begins; 4) the median plane (xz plane) ; and 5) Dental margin constraints.

[0158] 为避免与邻近牙齿以及相对颚上的牙齿碰撞,可能需要将附件放于临床牙冠中轴(FACC)附近。 [0158] In order to avoid a collision with adjacent teeth and the teeth on the opposite jaw may need to be put in the annex near the central axis of the clinical crown (FACC). 对于上部牙齿和下部牙齿两者来说,当牙齿较小时,需要短臂附件。 For both the upper teeth and lower teeth, the teeth when small, short arm attachment needs. 当附件较靠近FACC时,力矩可能因短臂的缘故而对旋转来说为不足。 When the attachment closer FACC, torque may vary because of the short arm and rotating it as inadequate. 此问题在下颚中是最相关的。 This problem in the jaw is the most relevant. 图26说明用于设计附件的算法中所使用的牙齿上的不同参数,当将附件放于FACC附近时, 所述附件产生足够的力矩。 Figure 26 illustrates the different parameters for dental algorithm used in the attachment on the attachment when placed near FACC, the annex to generate sufficient torque. 下文描述用于短臂附件定位的算法。 Short arm attachments described below for positioning algorithm.

[0159] 步骤1 :识别最大牙间搜索线。 [0159] Step 1: Identify the largest teeth among the search line. 如果搜索线在规则臂区内,那么定位具有规则附件解决方案的位置。 If the search line in the rules arm area, then locate the position of having a regular accessory solutions. 从牙间边界到FACC,且从切缘约束到牙龈线定向执行搜索。 From interdental border to FACC, and constraints from the cutting edge to the gum line directed to perform the search. 规则臂解决方案应满足所有约束。 Rules arm solution should satisfy all constraints. 如果找到解决方案,那么识别并实施所述解决方案。 If you find a solution, then identify and implement the solution. 如果无法在规则臂区中找到解决方案,那么执行步骤2以在短臂区中寻找解决方案。 If you can not find a solution in the rule-arm area, then step 2 in order to search for solutions in the short-arm region.

[0160] 步骤2 :对于搜索线上的每一位置点,计算潜在解决方案。 [0160] Step 2: For each position point search line, calculate the potential solutions. 通过旋转角函数来计算附件的旋转角。 By rotating angle function to calculate the rotation angle attachment. 还计算激励轴,接着执行步骤3。 Also calculated excitation axis, then the step 3.

[0161] 步骤3 :如果所有潜在解决方案都不满足约束,那么执行步骤4。 [0161] Step 3: If all of the potential solutions do not satisfy the constraints, then step 4. 否则,检查每一潜 Otherwise, check each dive

25在解决方案以确定满足所有约束。 25 solutions that satisfy all constraints. 将满足约束的解决方案进行比较,且选择最优解决方案。 The solution that satisfies the constraint compare and choose the best solution. 举例来说,选择臂的最大值作为最优解决方案。 For example, selecting the maximum value as the optimal solution for the arm.

[0162] 步骤4 :使扫描线以增量朝FACC移动。 [0162] Step 4: Make the scanning line incremental move towards FACC. 如果搜索线在FACC上或超过FACC,那么无法找到解决方案,且搜索终止。 If you search on line or over FACC FACC, you can not find a solution, and the search is terminated. 如果在到达FACC之前找到搜索线,那么执行步骤2以在短臂区中寻找解决方案。 If you find the search line before reaching the FACC, then step 2 in order to search for solutions in the short-arm region.

[0163] 图27说明作用附件表面的不同参数。 [0163] FIG. 27 illustrates the different parameters of the role of attachment surface. 实例参数包含:1)夹持平面的面积,其以夹持平面与牙齿表面之间的夹持多线与交叉多线为界;幻夹持平面与牙齿表面之间的交叉多线的长度;3)夹持多线与交叉多线之间的宽度(即,最大-最小距离);4)夹持平面的质心;5)臂向量,其垂直于Oz和夹持平面法线;6)臂长度,其为臂向量的带正负号长度,取决于基于右手定则而绕Oz的旋转;以及7) T值,其如下计算:((-平面法线向量·■臂向量)*Z 轴)*面积。 Examples of parameters include: 1) the area of the clamping plane, which to grip and clamp a multi-line between the plane and the tooth surface is bounded by a multi-line cross; Magic clamping length between the intersecting plane and the tooth surface of the multi-line; 3) the width of the clamping and multi-line multi-line between the crossing (i.e., maximum - minimum distance); 4) the clamping plane centroid; 5) arm vector, which is perpendicular to the clamping plane and normal Oz; 6) Arm length, which is a sign with the vector length of the arm, depending on the right-hand rule and based on the rotation around Oz; and 7) T value, which is calculated as follows: ((- Surface normal vectors · ■ arm vector) * Z axis ) * area.

[0164] 可调整参数以补偿短臂。 [0164] tunable parameters to compensate for the short arm. 举例来说,旋转可围绕附件的ζ轴发生以最大化力矩的ζ分量。 For example, the rotation may occur around the attachment axis ζ to ζ component maximize torque. 图观说明夹持平面旋转的比较。 Figure View Description holding relatively flat rotation. 如图的上部部分中所示,在不旋转、旋转30度和旋转60度的情况下,在牙齿的表面上提供附件。 As shown in the upper portion of FIG, without rotation, rotated 30 degrees and 60 degrees of rotation of the case, provided on the attachment surface of a tooth.

[0165] 激励件围绕激励轴旋转。 [0165] about the excitation axis activator. 参考图的下部部分,激励轴穿过附件的原点(0),且沿附件的Oz轴与附件的夹持平面的法线之间的交叉乘积(OR)而导向。 Lower portion of reference pictures, incentive axis through the accessory origin (0) and along the cross product (OR) normal attachments and accessories Oz axis between the clip plane and guide. 图观的左下部分展示附件,且图观的右下部分展示围绕激励轴(OR)旋转12度的激励件。 Lower left portion of the right lower part of the diagram shows accessory concept, and FIG concept shows around the excitation axis (OR) rotating 12 degrees activator.

[0166] 图四说明夹持平面的优化旋转角。 [0166] Figure IV indicates that the optimization clipping plane rotation angle. (内部)利用经校正的牙齿的ζ轴来测量夹持平面的旋转角。 (Internal) using the corrected teeth ζ axis to measure the angle of rotation of the clamping plane. 夹持平面的旋转角可在0°与60°之间。 Clipping plane rotation angle can be between 0 ° and 60 °. 如下确定优化旋转角: Optimization of the angle of rotation is determined as follows:

[0167] [0167]

旋转角=Ia' α-60° [60°, a >60° Rotation angle = Ia 'α-60 ° [60 °, a> 60 °

[0168] 可进行调整以补偿短臂的其它参数包含:1)夹持平面的平行平移,以调整作用表面的宽度和长度;以及2)围绕附件的χ轴的旋转,以调整附件宽度(见表1中的参数P5)。 [0168] Other parameters can be adjusted to compensate for the short arm comprises: 1) the clip plane parallel translation to adjust the width and length of the work surface; and 2) to rotate about the attachment χ axis to adjust the attachment width (see Table 1 Parameter P5).

[0169] 在制造附件/激励件对期间,应观察以下限制:1)由于可成形性限制,球体部分在直径方面的大小不得小于2mm。 [0169] In the manufacturing Accessories / activator pair period, should observe the following restrictions: 1) The formability limit sphere portion size in diameter shall not be less than 2mm. 2、附件不得在牙齿表面上产生使得材料无法与几何形状充分一致的大伸出物。 2, Annex may not produce on the tooth surface so that the material can not be fully consistent with the geometry of the big lugs. 举例来说,如果夹持平面的高度(见表1中的参数Li)过短,那么夹持平面的角度将过大,从而导致PRAA的不良成形的夹持平面。 For example, if the height of the clamping plane (see Table 1 Parameter Li) is too short, then the angle of the clip plane is too large, resulting in poor clamping plane PRAA formed. 因此,夹持平面的高度不得小于3mm。 Therefore, the height of the clip plane shall not be less than 3mm. 3)如果突出过低,那么力可能受损,因为接触因附件主体和激励件两者中的夹持平面表面上的面积和界定损失而不正确。 3) If the highlight is too low, then the force may be damaged, because the contact area and defined due to the loss of both the annex on the subject and encourage members of the clip plane surface without correct. 这由材料的可成形性和制造容差导致。 This formability and manufacturing tolerances result in the material. 4)在一个实施例中,附件的侧面弯曲,以提供到牙齿表面的平滑过渡。 4) In one embodiment, the side attachment curved to provide a smooth transition to the tooth surface. 这可便利热成形时的材料一致性。 This material may facilitate consistency hot molding. 幻沿附件的ζ轴的角度(见表1中的参数P7)应在避免材料在与铰链相对的端部裂开的范围内。 Magic angle along the ζ axis annex (see Table 1 in the parameter P7) should be avoided in the material at the end portion opposite the hinge split range.
