制造用于调整牙齿位置的牙科器械的方法 Manufacturing method for adjusting the position of the teeth of a dental instrument

技术领域 Technical Field

[0001] 本申请是有关口腔正畸领域,尤其是有关计算机辅助制造用于调整牙齿位置的牙科器械的方法。 [0001] The present application is related to the field of orthodontics, especially related to computer-aided manufacturing method for adjusting the position of the teeth of a dental appliance.

背景技术 Background

[0002] 传统的牙科正畸治疗是通过在牙齿上粘接带环、托槽等装置,利用矫正弓丝、弹簧、皮圈等矫正器械进行牙齿矫正。 [0002] The conventional orthodontic treatment on teeth by adhesive tape loop, brackets and other devices, the use of correct arch wire, spring, aprons and other equipment for orthodontic correction. 这种方法具有以下缺点:美观度、舒适度差;口腔卫生难以维护;临床医生需要较长时间的培训才能逐步掌握该技术;每次复诊医生都要花费大量时间调节矫治器,矫治过程复杂。 This method has the following disadvantages: aesthetics, comfort poor; oral hygiene is difficult to maintain; clinicians need longer training in order to gradually master the technology; each referral doctors have to spend a lot of time adjusting the appliance, the treatment process complicated. 相对于传统的托槽矫正器而言,隐形矫治技术不需要托槽和弓丝,采用的是一系列隐形矫治器。 Compared to traditional braces bracket, the invisible appliance technology does not require brackets and arch wires, using a series of invisible appliance. 该种隐形矫治器由安全的弹性透明高分子材料制成,使矫治过程几乎在旁人无察觉中完成,不影响日常生活和社交。 This kind of invisible appliances are made of transparent polymer material safety flexibility so that the treatment process is almost completed in others no notice, it does not affect the daily life and social. 同时,没有了粘结托槽、 调整弓丝的繁琐,临床操作大大简化,整个矫治过程省时又省力。 At the same time, there is no bonding brackets, arch wires tedious adjustments, greatly simplifying clinical operations, save time and effort throughout the treatment process. 因此目前无托槽隐形矫治方法为越来越多的人所采用。 There is currently no bracket invisible appliance method adopted by more and more people.

[0003] 隐形矫治器是计算机辅助设计技术、快速成型技术和新材料相结合的产物。 [0003] invisible appliance is computer-aided design, rapid prototyping technology and new materials combined with the product. 它是一种透明的、可自行摘戴的矫治器。 It is a clear, removable appliance worn yourself. 与传统矫治器一样,隐形矫治器也是通过在牙齿上施加适当的、可控制的力来使牙齿移动。 With traditional appliances like invisible appliance also by applying an appropriate, controlled force on the teeth to the teeth move. 施医者可通过计算机模拟矫正过程,并用医用弹性透明高分子材料为每一个过程制作一个矫治器。 Shi healer can cure process by computer simulation, and with medical flexible transparent polymer materials for each of the process of making a appliance. 整个矫治过程就是换用这一系列矫治器,在每次戴用时,牙齿都会有受力的感觉,并向该矫治器设计的位置移动。 Entire treatment process is replaced with the series appliance, each time wearing teeth will have the feeling of force, and to move the appliance design position. 每过一个周期(比如两周)更换下一副矫治器,牙齿就会从初始的畸形状态逐渐移动至正常排列状态,从而达到矫治效果。 Each had a period (such as two weeks) under a pair of replacement appliance, the teeth will move from the initial state of deformity gradually to normal alignment state, to achieve the treatment effect.

[0004] 隐形矫治器的制作目前有通过手工排牙生成模型后逐个压制,或通过计算机模拟排牙后生成数字模型,通过激光快速成型技术制作。 [0004] invisible appliance production currently manually after row of teeth one by one to suppress generation model, or generate a digital model after row of teeth, rapid prototyping technology to produce laser through computer simulation. 手工排牙是在取得病人牙颂印模并制成石膏模型后,对需要矫治的牙齿进行移位排列,并依照移位后的牙齿排列制成的模型压制隐形矫治器。 Hand row of teeth in the patient after obtaining dental impression song and made a plaster model, the need for treatment of teeth shift arrangement, and the arrangement is made in accordance with the model teeth shifted pressing invisible appliance. 其缺点是牙齿移动精度不够,生产效率低,难以实现批量定制。 The disadvantage is that tooth movement accuracy is not enough, low productivity, difficult to achieve mass customization. 目前的计算机模拟排牙方法是先获得最后或者目标牙齿状态,然后根据原始牙齿状态和最后牙齿状态,通过插值法获得多个中间牙齿状态。 The current computer simulation tooth arrangement method is to get the final goal teeth or state, and then the original dental status and last dental status, obtain a plurality of intermediate tooth status by interpolation. 其缺点是一旦确定最后牙齿状态,中间牙齿状态就已确定,故很难在牙齿矫正过程中避免牙齿碰撞,并很难为同一牙齿的不同操作单独地设置步长。 The disadvantage is that once the teeth to determine the final status, the status of the middle tooth had been identified, it is difficult to avoid in the course of orthodontic teeth collide, and it is difficult for the same tooth individually set different operating steps. 因此,需要一种兼具高效和灵活特点的排牙方法。 Therefore, efficient and flexible features of both the need for a tooth arrangement method.

发明内容 DISCLOSURE

[0005] 本申请的一方面提供了一种产生表示牙齿状态的数字数据集的方法,其包括:获取表示牙齿第一状态的第一数字数据集;提供至少一个操作符,用于修改表示牙齿状态的数字数据集;以及利用状态空间搜索法和操作符,基于第一数字数据集,产生表示第二牙齿状态的第二数字数据集。 On the one hand [0005] The present application provides a method of producing dental status represents digital data set, comprising: obtaining a first state showing teeth first digital data set; providing at least one operator to modify represent teeth state numeric data set; and the use of state-space search method and operators, based on the first set of digital data generated to indicate the status of a second dental second digital data set.

[0006] 在一些实施方式中,牙齿状态可以是上颂或下颂的状态。 [0006] In some embodiments, the state may be the maxillary dental or mandibular state. 在一些实施方式中,牙齿状态可以是上颂或下颂的部分的状态。 In some embodiments, the maxillary dental status or condition may be part of the mandible. 在一些实施方式中,牙齿状态可以是上颂与下颂的状态。 In some embodiments, the state may be the maxillary teeth and mandibular state. 在一些实施方式中,牙齿状态可以是上颂与下颂的部分的状态。 In some embodiments, the teeth can be a part of the state under the Song and Song of the state. 在一些实施方式中, 牙齿状态可以只包括单颗牙齿。 In some embodiments, dental status may include only a single tooth. 在一些实施方式中,牙齿状态可以包括多颗牙齿。 In some embodiments, dental status may include multiple teeth.

[0007] 状态空间搜索法把问题求解过程转换为寻找从初始状态到目标状态的路径的过程。 [0007] state-space search method converts the problem solving process to find a path from the initial state to target state process. 可以把状态空间搜索法用三元组来表示:[S,0,G],其中,S是初始状态的集合,0是操作符集合,G是目标状态的集合。 You can use the state-space search method triples to represent: [S, 0, G], where, S is the set of initial state, 0 is the set of operators, G is the set of target states. 对当前状态应用一次操作符,将引起状态的改变,从而达到一个新的状态。 The current state of the application once the operator, will cause a change of state, so as to achieve a new state.

[0008] 所有状态的集合可以用状态图来表示。 [0008] The set of all states can be represented by a state diagram. 在状态图中,一些状态是目标状态,如果我们找到了由开始状态到达目标状态的路径,问题就获得了解答。 In the state diagram, some of the state is the target state, if we find a path from the start and reach the target state, the problem is to get the answer. 解答就是由开始状态到达目标状态为了进行状态转换所使用的一系列操作符。 Answer is to reach the goal state from the start state operator to carry out a series of state transitions used. 如果路径是最短的,我们可以把这条路径叫最优解。 If the path is the shortest, we can call this path the optimal solution.

[0009] 常用的状态空间搜索有深度优先和广度优先。 [0009] The commonly used state-space search depth and breadth-first priority. 广度优先是从初始状态一层一层向下找,直到找到目标为止。 Breadth-First is one level down from the initial state to find until you find the target so far. 深度优先是按照一定的顺序先查找完一个分支,再查找另一个分支。 Depth priority is to finish in a certain order to find a branch, then find another branch. 前面说的广度和深度优先搜索都是盲目搜索。 He said earlier the breadth and depth first search is blind search. 状态空间搜索法还包括启发式搜索。 State-space search method also includes heuristic search.

[0010] 启发式搜索是在状态空间中的搜索对每一个搜索的节点进行评估,得到最好的节点,再从这个节点进行搜索直到目标。 [0010] heuristic search is a search carried out in the state space search for every node assessment, get the best node, and then from the search until the target node. 这样可以提高搜索效率。 This can improve search efficiency.

[0011] 启发式搜索中对节点的估价是用估价函数表示的,估价函数可以用以下方程式来表不: [0011] heuristic search in the valuation of a node is expressed as a function of the valuation, the valuation function can not use the following equation to the table:

[0012] f(n) = g (η) +h (η) 方程式(一) [0012] f (n) = g (η) + h (η) equation (a)

[0013] 其中f (η)是节点η的估价函数,g(n)是在状态空间中从初始节点到η节点的实际代价,h(n)是从η到目标节点最佳路径的估计代价。 [0013] where f (η) is the node η valuation function, g (n) is in the state space from the initial node to the actual cost of η nodes, h (n) is the estimated cost of the η the best path to the destination node . 在这里主要是h(n)体现了搜索的启发信息,而g(n)是已知的。 Here is mainly h (n) reflects the heuristic information search, and g (n) are known. g(n)代表了搜索的广度的优先趋势。 g (n) represents the priority trends in search of breadth. 但是当h(n) >> g(n) 时,可以省略g (η),而提高效率。 But when h (n) >> g (n) may be omitted g (η), and improve efficiency. 实际应用中,对新生成的一批节点计算估价函数,比较计算结果,取估价值最小的节点作为新的出发点继续搜索,直到达到目标节点。 The practical application of the new generation of batch computing node evaluation function, compare the results, taking the minimum estimated value of the node as a new starting point to continue the search until it reaches the destination node.

[0014] 可以用状态空间搜索法来制定正畸治疗计划。 [0014] state-space search method can be used to develop orthodontic treatment plan. 其中,初始状态是患者的原始牙齿状态;操作符集合可以包括空操作、拔牙、邻面去釉、平动、旋转等;目标状态集合是符合临床医生制订的矫正要求的牙齿状态的集合。 Among them, the initial state is the state of the patient's original teeth; operator set may include air operations, extractions, interproximal enamel, translation, rotation, etc; target state set is a collection of clinicians to develop in line with the requirements of corrective dental status.

[0015] 在本申请中,在大部分情况下,节点、状态以及数字数据集可以互换使用。 [0015] In the present application, in most cases, node status, and digital data set can be used interchangeably.

[0016] 操作符是一种离散计算机运算操作。 [0016] operator is a discrete computing operations. 当在一颗牙齿上应用一个操作符,计算机将对应地修改表示当前牙齿状态的数字数据集,获得表示该牙齿被相应操作后的牙齿状态的数字数据集。 When applied on a tooth an operator, the computer will correspondingly modified representation of the current state of the digital data set of teeth, the teeth were obtained showing the appropriate action after dental state numeric data sets. 比如,当选择在第一牙齿上应用沿X轴正向平移Imm的操作符,计算机将修改表示当前牙齿状态的数字数据集,修改后的数字数据集表示在当前牙齿状态的基础上第一牙齿沿X轴正向平移了Imm后的牙齿状态。 For example, when you select the application along the X axis on the first tooth forward translation Imm operator, the computer will modify the representation of the current state of the digital data set of teeth, the modified digital data set represents the basis of the current state of the teeth on the first tooth translation along the X axis positive state Imm teeth after.
