Description

制造用于调整牙齿位置的牙科器械的方法 A method for producing a tooth for adjusting the position of the dental appliance

技术领域 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] This application is related to the field of orthodontics, in particular about the method for adjusting the CAM tooth positions of the dental instruments.

背景技术 Background technique

[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 is an orthodontic band by an adhesive ring device, the bracket on the tooth, etc., by the correction archwire, spring, aprons and other orthotics. 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 difficult to maintain; clinicians need training to a long time and 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。 With respect to the conventional bracket braces, brackets technique does not require invisible appliance and archwire, it uses 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 security appliance is made of transparent elastomeric polymeric material treatment process is almost completed so that no notice of the others, 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 wire tedious adjustments, clinical operation greatly simplifies the entire treatment process save time and effort. 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 method bracket invisible appliance is used 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 a computer-aided design technology, new materials, and rapid prototyping technology product of the combination. 它是一种透明的、可自行摘戴的矫治器。 It is a transparent, self-removable appliance worn. 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。 Like the conventional appliance, the appliance is invisible to the teeth moved by applying an appropriate force can be controlled on the teeth. 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。 Medical application may cure process by computer simulation, with medical and elastomeric transparent polymer for each process of making an 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。 The entire treatment process is switching to this series of appliances each time wearing teeth will have the force of feeling, and 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) at a replacement appliance, the teeth will move progressively from the initial abnormal state to a normal alignment state, so as 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。 Production [0004] There is invisible appliance after pressing by hand one by one row of teeth generate a model, or generate a digital model of tooth arrangement, laser light is produced by rapid prototyping technology by 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 is made in the patient and the dental impression is made of plaster Chung model, the need for treatment of the teeth shift arrangement, and the arrangement pattern is produced in accordance with the pressing invisible appliance shifted teeth. 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 not enough tooth movement precision, 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 method of computer simulation teeth arrangement is to obtain the final state or target tooth and tooth according to the original state and the final state of the tooth, to obtain a plurality of intermediate teeth state 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 last determined state of teeth, tooth intermediate state had been identified, it is difficult to avoid a collision in the tooth during orthodontic, and it is difficult for the same tooth arranged separately different operating steps. 因此,需要一种兼具高效和灵活特点的排牙方法。 Thus, efficient and flexible characteristics of the teeth arrangement is needed is a method of both.

发明内容 SUMMARY

[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。 In one aspect [0005] The present disclosure provides a method of generating digital data represented by a state set of teeth, comprising: obtaining a first state showing a first digital data set teeth; providing at least one operator to modify represent teeth digital data set state; and the state space search method and operators, based on the first digital data set, generating a second digital data set representing a second state of the teeth.

[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 a maxillary tooth or a 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 state may be a maxillary tooth or a mandibular portion of the state. 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 a tooth of the maxillary 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 state may be a tooth portion Song and mandibular status. 在一些实施方式中, 牙齿状态可以只包括单颗牙齿。 In some embodiments, the state may comprise only a single tooth teeth. 在一些实施方式中,牙齿状态可以包括多颗牙齿。 In some embodiments, the state may include a plurality of teeth, 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 to convert the process to find the path from initial state to target state process of problem solving. 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。 The state-space search method can be used to represent the triad: [S, 0, G], where, S is the set of initial state, 0 is the set of operators, G is the set target state. 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。 A current state of the application 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 to the target state from the start state, the problem is to get the answers. 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。 It is answered by the state of reaching the target state to start a series of state transitions operator 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 put the path is called the optimal solution.

[0009] 常用的状态空间搜索有深度优先和广度优先。 [0009] 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 priority is to find one level down from the initial state, 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 is preferentially in a certain order to locate a complete branch, and then look for the other 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 in the state space of the search for each node to assess, best node, then this node until the destination search. 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 represented by a cost function, cost function can use the following equation table is not:

[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) [eta] of the node cost function, g (n) is in the state space from the initial node to the actual cost of the node [eta], h (n) is an estimate of the cost of [eta] from 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 are the main h (n) reflects the heuristic information search, and g (n) is known. g(n)代表了搜索的广度的优先趋势。 g (n) represents the breadth of the priority trends in search. 但是当h(n) >> g(n) 时,可以省略g (η),而提高效率。 However, when h (n) >> g (n), may be omitted g (η), and to 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。 Practical application, the evaluation function is calculated on the number of newly generated node, compare the results, take 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。 Wherein the initial state is the original state of the patient's teeth; may include a set of operators op, extraction, interproximal enamel, translation, rotation and the like; target state is the set of teeth correction state meets the requirements as established by the clinician.

[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] The operator is a discrete computer arithmetic operation. 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 modify the corresponding digital data set represents the current state of the teeth, to obtain digital data set represents a state after the teeth of the tooth is correspondingly operation. 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 the application selected along the X axis in a first translational forward tooth Imm operator, the computer will modify the digital data set represents the current state of the teeth, the modified digital data set represents the basis of the current state of the teeth on the first tooth along the X-axis positive translation teeth state after Imm.
