发明背景1.发明领域本发明总体上涉及正牙学技术领域。 BACKGROUND OF THE INVENTION 1. Field of the invention relates to orthodontic TECHNICAL FIELD The present invention generally. 更具体地说,本发明涉及一种使牙齿从原始牙齿布局逐渐移位到最后牙齿布局的方法和装置。 More particularly, the present invention relates to a tooth from the original layout of the teeth gradually shifted to the method and apparatus of the final tooth arrangement.

为了美观或其他理由而重新定位牙齿通常是用戴上一般称为“牙托”的用具来实现的。 For aesthetic or other reasons to reposition the teeth is usually used to wear generally known as "mouthpiece" of equipment to achieve. 这种牙托包括各种器械,例如:托架、拱形钢丝、连线和O形圈。 This tray includes a variety of instruments, such as: brackets, arch wires, cables and O-rings. 把这些器具安装在患者的牙齿上是冗长而费时的事情,需要多次会见主治的牙医。 These instruments mounted on the patient's teeth is tedious and time-consuming thing, you need to repeatedly met the attending dentist. 因此,传统的正牙治疗限制了正牙医生治疗患者的数量,并且正牙治疗的费用十分昂贵。 Therefore, the conventional orthodontic treatment limits the number of patients treated with the orthodontist, and the cost of orthodontic treatment is very expensive.

在把牙托固定在患者的牙齿上之前,一般至少要与正牙医生、牙医和/或X光照相室约见一次,以便取得患者牙齿和颚部的X光透视和相片。 Before the denture is fixed on the patient's teeth, usually at least once an appointment with the orthodontist, dentist and / or X-ray photography room, in order to obtain the patient's teeth and jaw X-rays and photographs. 在初次会见时,或者也可能在以后会见时,一般还要制作一付患者牙齿的蛋白藻蛋白酸盐模子。 At the first meeting, or possibly at a later meeting, the general also produced a pair of proteins in patients with dental alginate mold. 这种模子提供了患者牙齿的模型,正牙医生可以将X光透视和照相与这种模型结合起来提出一个治疗方案。 This provides the patient dental mold model, the orthodontist can X-ray and photographic and combine this model to propose a treatment plan. 然后,在把牙托安装到患者的牙齿上期间,正牙医生一般还要诊治一次或多次。 Then, during the tray attached to the patient's teeth, orthodontists general also for treatment once or several times.

在第一次安装牙托的诊治中,最初要用弱酸处理牙齿的表面。 In the first installation of a tray of diagnosis and treatment, the initial use of weak acid treated surface of the teeth. 这种酸要选择的最主要性能是要粘结在牙齿上的托架和箍圈与牙齿表面的粘结性能。 The main properties of this acid is to be selected to be bonded and the bonding properties of the bracket and the tooth surface of the ferrule on the tooth. 上述托架和箍圈的作用是用作以后增加上去的器械的紧固件。 The action of the carriage and increase the ferrule is used up after the fastener devices. 在酸处理步骤之后,用适当的粘结材料把托架和箍圈粘结在患者的牙齿上。 After the acid treatment step, with a suitable adhesive material to bond the carrier and the ferrule on the patient's teeth. 在粘结固化之前,不要施加产生力量的器具。 Before bonding curing, do not apply appliance produce power. 因此,正牙医生通常要安排一次以后的预约,以保证托架和箍圈能良好地粘结在牙齿上。 Therefore, the orthodontist usually arrange a later appointment to ensure that the bracket and the ferrule can well bonded to the teeth.

在一组传统的牙托上施加力量的主要器械是拱形钢丝(archwire)。 The main instrument applied force on a set of conventional denture is arch wire (archwire). 这种拱形钢丝是有弹性的,利用托架上的窄缝固定在托架上。 This arch wire is elastic, the slit on the use of the bracket fixed to the bracket. 这种拱形钢丝把许多托架联系在一起,并对其施加力量,以便经过一段时间之后使牙齿移位。 This arch wire to the bracket together many, and force is applied thereto, so that after a period of time for the displacement of teeth. 扭转钢丝或者合成橡胶的'O'形圈常常用于加强拱形钢丝在托架上的固定。 Torsion wire or synthetic rubber 'O' rings are often used to enhance the arch wire is fixed to the bracket. 在正牙技术领域中,把拱形钢丝固定在托架上常常称为“绑扎”,而在这种工序中所使用的钢丝则称为“绑扎线”。 In orthodontic art, the arch wire to the bracket is often referred to as "banding", and in this step the wire used is called "binding thread." 合成橡胶'O'形圈则称为“塑料”。 Synthetic rubber 'O' ring is called "plastic."

拱形钢丝就位后还要定期到正牙医生处就诊,这时,要安装各种具有能产生不同力量的性能的拱形钢丝,或者更换或拉紧已有的绑扎线。 After the arch wire in place but also regular visits to the orthodontist at this time, has to be installed to produce the performance of a variety of different forces of arch wire, or replace or tighten existing banding line. 一般,这种就诊是预约的,每3-6周一次。 Generally, this treatment is reserved, every 3-6 weeks.

如上所述,使用传统的牙托是很漫长而费时的过程,需要多次到正牙医生处就诊。 As noted above, the use of conventional denture is very long and time-consuming process, requiring multiple visits to the orthodontist office. 此外,从患者的观点来说,使用牙托既难看又不舒服,有感染的危险,还使得刷牙、剔牙和其他牙科卫生处理做起来很困难。 In addition, from the patient's point of view, the use of denture both ugly and uncomfortable, there is the risk of infection, but also makes brushing, flossing, and other dental hygiene treatment to make it so difficult.

为此,就很需要提供其它的可替换的牙齿重新定位的方法和装置。 For this reason, it is desirable to provide a method and apparatus other alternative tooth repositioning. 这种方法和装置应该是经济的,特别是应该减少正牙医生在为每一个患者进行策划和照料时所耗费的时间。 This method and apparatus should be the economy, especially to reduce the orthodontist should be planned at the time and care for each patient the time-consuming. 这些方法和装置还应该更容易为患者所接受,特别是应该做到就诊的次数较少,比较舒服,感染的可能性少,并且更便于日常的牙齿卫生保养。 These methods and devices should also be more easily accepted by patients, and less should be done in particular the number of visits, more comfortable, less possibility of infection, and easier to maintain dental hygiene routine. 以下描述的本发明的方法和装置至少能达到以上所述的目的中的一部分。 The method and apparatus of the present invention described below, at least in part to achieve the purpose described above.

发明概述本发明提供了一种经过改进的,用于将牙齿从原始牙齿布局重新定位到最后牙齿布局的方法和装置。 Summary of the Invention The present invention provides an improved, from the original tooth for tooth repositioning layout method and apparatus of the final tooth arrangement. 重新定位是用这样一种装置来实现的,这种装置有一系列设计成能把牙齿容纳在一个空腔内的器械,并用一系列步骤逐渐使各个牙齿重新定位。 Re-positioning is achieved in such a device, which device has a series of teeth designed to be able to receive in a cavity of the instrument, and with a series of steps so that each tooth progressively repositioned. 以上所述的一系列步骤至少是三个逐次的步骤,一般包括至少四个逐次的步骤,常常包括至少十个步骤,有时要包括至少25个步骤,而且偶然可能包括40个或更多的步骤。 A series of steps described above is at least three successive steps, usually including at least four successive steps, often including at least ten steps, sometimes including at least 25 steps, but occasionally may include 40 or more steps . 最经常的是,这种方法和装置用10个到25个逐次的步骤来使牙齿重新定位,虽然在复杂的情况下有许多患者的牙齿要用40个或者更多的步骤。 Most often, such a method and apparatus for 10-25 successive steps to reposition the teeth, although there are many patients teeth use 40 or more steps in the complex case. 逐次使用一系列器械可以把每一种器械设计成以很小的移位量移位每一颗牙齿,一般小于2mm,优选是小于1mm,最好是小于0.5mm。 Successive series of instruments can be used for each device is designed with a very small amount of shift Shift each tooth, generally less than 2mm, preferably less than 1mm, preferably less than 0.5mm. 这些限制是利用单独一种器械时,在一颗牙齿上的任何一点上的最大线性移位量。 These limitations are the use of a single instrument, the maximum amount of linear displacement at any point on a tooth. 当然,由逐次的器械所形成的移位对于任何一颗特定的牙齿来说常常是不相同的。 Of course, the device is formed by successive shift for any one particular tooth is often not the same. 因此,由于使用一种器械的结果,一颗牙齿上的某一点可以移位一个特定的距离,然后,用下一个器械再使这一点在相同或不同的方向上移位不同的距离。 Therefore, the use of an instrument result, a point can be shifted a specific distance on the tooth, and then, with the next so that the shift device further different distances on the same or different directions.

单个器械通常是一个具有能在内部容纳牙齿的空腔的聚合物壳体,一般用下述的方法模制而成。 Usually a single device to accommodate the teeth in a polymer housing having an internal cavity, in general by the following method molded. 每一个单个器械通常是这样设计的,即,它的容纳牙齿的空腔的几何形状与该器械所要达到的牙齿的中间布局或最后位置相适应。 Each individual device is typically designed so that its tooth receiving cavity geometry of the device to be achieved by the tooth arrangement or the last intermediate position adapted. 这就是说,当患者第一次戴上这个器械时,全部牙齿中的某些牙齿将与该器械空腔的未变形的几何形状错位。 That is, when the patient first put on the equipment, all the teeth of some misplaced teeth will not deform the geometry of the instrument cavity. 但是,这种器械有足够的弹性去适应或符合错位的牙齿,并且将对这颗错位的牙齿施加足够的弹性力量,以便使这颗牙齿重新定位到这个治疗步骤所要达到的中间布局或最后位置。 However, this device has sufficient flexibility to adapt or conform misaligned teeth, and will exert Zheke dislocation teeth sufficiently resilient force, so that the repositioning of the tooth to the intermediate position of the layout or the last step to be achieved by treating .

按照本发明的装置包括至少一个第一器械,该第一器械具有选定的、使患者的牙齿从原始牙齿布局重新定位到各牙齿要逐渐重新定位到上面的第一中间布局上的几何形状。 The apparatus according to the present invention comprises at least one first device, the first device having a selected, so that the patient's teeth from the original layout of the teeth to be repositioned to the respective teeth progressively repositioned to the geometry of the first intermediate arrangement on top. 这种装置还包括至少一个中间器械,它具有选定的、逐渐使牙齿从上述第一中间布局重新定位到一个或几个逐次的中间布局上的几何形状。 The device further includes at least one intermediate device, which has a selected, progressively from the teeth of the first intermediate arrangement to reposition the geometry of one or several successive intermediate layout on. 这种装置还包括一个最后的器械,它具有选定的,逐渐使牙齿从最后的中间布局重新定位到所要求的最后牙齿布局上的几何形状。 Such apparatus also includes a final device, it has selected, so that the tooth gradually from the last intermediate arrangement to reposition the geometry of the last tooth on the desired layout. 在有些情况下,需要把最后的一个或几个器械做成使得最后的牙齿布局“矫枉过正”,这一点下面还要详细讨论。 In some cases, one or more of the last instrument formed such that the final tooth arrangement "overkill", but also discussed in more detail below this point.

如将要在下面结合本发明的方法更详细地描述的,这种装置是可以设计的,而且全部单个器械在治疗一开始就制造好,这样,就能把这些器械作为单独的一套器械或一套装置提供给患者。 As will be combined with the method of the present invention is described below in more detail, such a device can be designed, and all individual devices at the beginning of treatment manufactured good, so that these devices can be set as a separate device or a set of devices available to patients. 器械的使用次序要清楚地标明(例如用逐次的数字),这样,患者就能够按照正牙医生或其他治疗专业人员所规定的频率把这些器械套在牙齿上。 Order to use the instrument clearly marked (e.g. with successive numbers), so that the patient will be able to follow the frequency of the orthodontist or other treating professional prescribed set of these instruments in the teeth. 与使用牙托不同,这种患者不需要每次都到专业治疗人员那里去,就能够进行治疗上的调节。 With the use of different denture, which the patient does not need to always go to a professional therapist, it can be adjusted on the treatment. 虽然患者一般还需要周期性地去专业治疗人员那里,以确认治疗是按照原来的计划进行着,但确不需要每次都到专业人员那里去进行调节,这样就能以更多但更小的连续的步骤进行治疗,同时还减少了专业治疗人员为每一个患者所花费的时间。 Although patients generally need to periodically go to a professional therapist there, to make sure the treatment is carried out in accordance with the original plan, but they do not need to go there every time to adjust to the professionals, so you can order more but smaller sequential treatment steps, while also reducing the time for the treating professional every patient takes. 此外,由于患者有能力自己使用这种更舒服、看不见、并且可以拆卸的聚合物的外壳器械,因而大大改进了患者的配合、舒适和满意的程度。 In addition, because patients have the ability to use this more comfortable, invisible and removable shell polymer devices, thus greatly improved the fit, comfort and satisfaction of patients.

按照本发明的一种方法,在患者的嘴里放置了一系列逐渐定位的调节器械,以使患者的牙齿从原始的牙齿布局重新定位到最后的牙齿布局。 A method according to the present invention, the patient's mouth and placed in a series of gradual positioning adjustments to the instrument, so that the patient's teeth from the original layout reposition teeth to the final tooth arrangement. 非常方便,这种器械不是固定的,患者可以在治疗过程中随时放置或重新放置器械。 Very convenient, this device is not fixed, the patient can be placed or repositioned at any time during the treatment instrument. 在一系列器械中的第一个器械要选择这样的几何形状,它能把牙齿从原始的牙齿布局重新定位到第一中间布局上。 In the first series of the instrument to be selected such instrument geometry, it can teeth from the original layout of the tooth repositioning to a first intermediate arrangement. 在接近或者到达第一中间布局之后,再逐次地把一个或多个附加的(中间的)器械放置在牙齿上,此时,这种附加的器械所选择的几何形状要能逐渐使牙齿从第一中间布局逐次重新定位到若干个中间布局上。 After approaching or reaching the first intermediate layout, and then successively to one or more additional (intermediate) the instrument is placed on the teeth, at this time, this additional device geometry selected to be able to gradually make the teeth from the first an intermediate layout successive repositioned onto several intermediate layout. 当把最后一个器械放入患者的嘴里时,治疗就可以结束了,此时,这个最后的器械所选定的几何形状能逐渐把牙齿从最后一个中间布局重新定位到最后的牙齿布局上。 When the last one instrument into the patient's mouth, the treatment can be the end of this time, the final geometry of the selected instrument can gradually teeth from the last intermediate to the final layout reposition teeth layout. 在一系列器械中的最后一个器械或者最后几个器械要选择这样的形状,使得牙齿的位置过度地矫证,即,要有一个使各个牙齿移位到超出选定的“最后”位置的几何形状(如果完全到位的话)。 In the last series of the instrument or device to select the last several devices in such a shape, such that the position of the teeth permits excessive correction, i.e., so that all the teeth have a shift beyond the selected "final" position of the geometric shape (if fully in place then). 为了在重新定位的方法终止之后抵消潜在的反弹,这种过度矫正是必要的,也就是说,允许各个牙齿会向着矫正之前的位置稍稍移位。 After repositioning to a method of terminating offset potential rebound, this excessive correction is necessary, that is, toward the teeth will allow the individual to correct position before shifting slightly. 过度矫正还有利于加快矫正的速度,即,使一个器械的几何形状的位置超过所要求的中间或最后位置,各颗牙齿就会以更快的速度向这个位置移位。 Intermediate or final position will also help speed up the correction of excessive correction speed, that is, the position of the geometry of an instrument exceeds the requirements of the respective teeth will shift faster to this position. 在这种情况下,可以在牙齿到达由这个或这几个最后的器械所确定的位置之前就结束治疗。 In this case, the tooth can be reached by this or these prior to the last device on the determined position of the end of treatment. 上述方法一般包括放置至少两个附加的器械,常常要放置至少10个附加器械,有时要放置至少25个附加器械,偶尔要放置至少40个或更多的附加器械。 The method generally includes placing said at least two additional devices, often placing at least 10 additional instruments, sometimes placing at least 25 additional instruments, occasionally to be placed at least 40 or more additional devices. 当牙齿接近(在预先选定的公差范围内)或者已经到达这一治疗阶段的最后目标位置时,就要更换为后续的器械,一般是在2-20天的间隔范围内更换,经常是在5-10天的间隔范围内。 When the tooth near (within a preselected tolerance) or have reached the final target position of the treatment phase, to be replaced for a subsequent instrument, generally be replaced within the range of 2-20 day intervals, often at in the interval of 5-10 days.

有可能常常需要在牙齿实际上到达该治疗阶段的“最后”位置之前就更换器械。 There may often require dental treatment is actually reaching the stage of the "final" position on the replacement of equipment before. 应该理解,当牙齿逐渐重新定位,并接近由一个特定的器械所确定的几何形状时,在这颗牙齿上的重新定位的力将大大地减小。 It should be understood, when the teeth gradually repositioned and approach by a particular device when the determined geometry, force repositioned on the tooth will be greatly reduced. 因此,及早在牙齿还只有被前一个器械部分定位时,就用后一个器械来更换前一个器械,就能缩短整个治疗的时间。 Therefore, early in the teeth when still only partially positioned in front of a instrument, the former on the latter with an instrument to replace an appliance, you can shorten the treatment time. 因此,FDDS实际上能代表最后牙齿布局的过度矫正。 Therefore, FDDS overcorrection can actually representative of the final tooth arrangement. 这样,既加快了治疗,又能抵消患者的反弹。 Thus, not only to speed up the treatment, but also to counteract the patient's rebound.

一般,转换到下一个器械要根据很多因素。 In general, the transition to the next instrument according to many factors. 最简单的方式是可以按照预定的日程表或按照固定的时间间隔(即每个器械的天数)来更换,这个间隔是在一开始根据预期的要求或者典型患者的反应确定的。 The easiest way is to be in accordance with a predetermined schedule, or according to a fixed time interval (i.e. number of days for each instrument) to replace, in the beginning of this interval is determined according to the reaction requirements of expected or typical patient. 换一种方式,也可以把具体患者的反应考虑在内,例如,当患者不再感觉到目前这个器械施加在牙齿上的压力时,即,患者很容易把这个器械戴在他的牙齿上,而且牙齿上没有受到什么压力或者不舒服时,就可以换用下一个器械。 Put another way, you can also consider the specific patient's reaction, including, for example, when a patient no longer feel the pressure of this equipment is currently applied to the teeth, that is, the patient can easily put this instrument worn on his teeth, and not subject to any pressure on the teeth or uncomfortable, you can switch to the next instrument. 在有些情况下,对于那些牙齿的反应很快的患者,专业治疗人员也可以决定跳过一个或者几个中间器械,即,减少使用的器械的总数,使它少于最初确定的数量。 In some cases, the reaction of those teeth for the patient quickly, the treating professional may decide to skip one or more intermediate devices, i.e., to reduce the total number of use of the instrument, so that it is less than the first determined number. 这样,就能缩短特定患者所需要的整个治疗时间。 This can shorten the treatment time required for the particular patient.

另一方面,本发明的方法是利用若干器械来重新定位牙齿,这种器械包括带有空腔的聚合物外壳,空腔的形状做成能容纳牙齿,并弹性地重新定位牙齿,从而产生最后的牙齿。 On the other hand, the method of the invention is the use of a number of devices to reposition the teeth, this instrument comprises a polymeric shell having a cavity, the cavity is sized to accommodate the shape of the teeth, and resiliently reposition teeth to produce a final teeth. 本发明还提供了这种方法的改进型,它在治疗一开始就确定至少三个上述器械的几何形状,患者要逐次戴这三个器械,以便把牙齿从原始的牙齿布局重新定位到最后的牙齿布局上。 The present invention also provides an improved method of this kind, it is determined at the outset of treatment geometries at least three of the above-described device, the patient to wear the three successive instrument to the teeth from the original layout reposition teeth to the final tooth layout. 优选地,在开始时至少确定四个几何形状,常常是至少10个几何形状,经常是至少25个几何形状,有时候是40个或更多的几何形状。 Preferably, at the start of determining the geometry of at least four and often at least ten geometries, frequently at least 25 geometry, and sometimes forty or more geometries. 如上所述,一般,由每一个后续几何形状的空腔所确定的牙齿布局与由前一个几何形状的空腔所确定的牙齿布局的差别不大于2mm,优选不大于1mm,最好是不大于0.5mm。 As described above, in general, the difference between the layout of the front teeth by one tooth arrangement and geometry of the cavity by each successive cavity geometry determined by the determined not greater than 2mm, preferably no more than 1mm, preferably not more than 0.5mm.

本发明的又一个方面是提供用来产生一组代表最后的牙齿布局的数字数据组的方法。 Yet another aspect of the present invention is to provide a method for generating a set of digital data set representing the last teeth layout. 这种方法包括:提供一组代表原始牙齿布局的原始数据组,并呈现出根据这一组原始数据的可视影象。 This method comprises: providing a set representing the original layout of the original data set of teeth, and showing the raw data in accordance with this set of visual images. 然后,处理这个可视影象,在该可视影象中重新定位各个牙齿。 Then, the process that the visual image to reposition individual teeth in the visual image. 然后,产生一组最后的数字数据集,这一组数据代表具有在可视影象中显示出来的重新定位的牙齿的最后牙齿布局。 Then, generating a set of final digital data set, this set of data represents a final tooth arrangement is displayed in a visual image to reposition the teeth. 原始数字数据集可以很方便地用现有技术来提供,包括数字化X射线影象,由计算机辅助的层析X射线扫描(CAT扫描)所产生的影象,由磁谐振造象(MRI)所产生的影象等等。 Original digital data sets can be easily provided by the prior art, including digitizing X-ray images, images by computer-aided tomography X-ray scan (CAT scan) generated by the image created by the magnetic resonance (MRI) by generated images and so on. 优选地,这种影象是立体影象,而数字化则可以用常规技术来完成。 Preferably, such an image is a perspective images, digitized can be accomplished by conventional techniques. 一般,原始数字数据集是借助于用常规技术制作一个患者在治疗之前的牙齿的石膏铸件。 Usually, the original digital data sets are produced by conventional techniques by means of a patient prior to treatment of the dental plaster cast. 然后,对所制成的石膏铸件用激光或其他扫描设备进行扫描,产生一个患者牙齿的石膏铸件的高分辨率的数字图像。 Then, the cast made of plaster is scanned with a laser or other scanning equipment to produce a patient's teeth plaster cast high-resolution digital image. 使用石膏铸件是最佳选择,因为它不必让患者暴露在X射线下,或者让患者忍受不愉快的MRI扫描。 Using plaster cast is the best choice, because it does not expose the patient X-rays, or to enable patients to tolerate unpleasant MRI scan.

在一个优选实施例中,也可以用标准的方法取得一个患者的蜡咬印。 In a preferred embodiment, the method can also be used to obtain a standard patient wax bite plate. 这种蜡咬印能让患者的上、下牙齿形状的石膏铸件放在互相咬合的中心位置上。 The wax bite allows printing on a patient, the shape of the lower teeth plaster cast at the center of the upper intermeshing. 然后,对这一对铸件扫描,以提供在这个位置上的颚部相对位置的信息。 Then, this casting is scanned to provide information on the relative position in this position of the jaw. 然后,把这种信息合并入两个拱形的IDDS中。 Then, this information is incorporated into the two arched IDDS.

一旦获得了数字数据集,就能在装备有计算机辅助设计软件的合适的计算机系统上显示并处理影象。 Once the digital data set, you can display and process images on a computer-aided design software, equipped with suitable computer system. 这一点下面还要更详细的描述。 Also described in more detail below this point. 影象的处理通常包括确定各个牙齿中的至少一些周围的边界,并借助于通过计算机处理上述影象,使牙齿的影象相对于颚部和其他牙齿移位。 Image processing generally includes determining the boundary around each of at least some of the teeth, and by means of the above-described image processing by the computer, so that the teeth of the image with respect to the jaw and other teeth shift. 本发明还提供了用于检测牙齿齿尖的信息的方法。 The present invention also provides a method for detecting the teeth of prongs information. 影象的处理可以完全凭主观进行,即,使用者可以单凭对影象的观察,以一种审美和/或治疗所要求的方式,简单地重新定位牙齿。 Image processing can be carried out entirely subjective, that is, the user can observe the image alone right to an aesthetic and / or treatment in the required way, simply reposition teeth. 或者,上述计算机系统可以设置一些规则和算法,来帮助使用者重新定位牙齿。 Alternatively, the computer system can set up some rules and algorithms to help users reposition teeth. 在有些情况下,有可能提供以完全自动的方式,即不用使用者介入的方式,来重新定位牙齿的规则和算法。 In some cases, there may be provided in a fully automated manner, i.e. without user intervention way to reposition the teeth of rules and algorithms. 一旦各个牙齿重新定好位之后,就会产生一组代表所要求的最后的牙齿布局的最后数字数据集,并储存起来。 Once again a good bit of each tooth, it will produce a desired final group represents the last digit of the layout of the data set of teeth, and stored.

对于专业治疗人员而言确定最后的牙齿布局的优选方法是确定最后牙齿的布局,例如,写出一个治疗方案。 For the purposes of treating professional to determine the final tooth arrangement preferred method is to determine the final layout of the teeth, for example, write a treatment plan. 使用治疗方案来确定正牙程序所要求的结果在本技术领域是公知的。 Use regimen to determine the result of orthodontic procedures required in the art is well known. 当形成了一个治疗方案或者其他最后的目标时,然后就能处理上述影象以符合这个方案。 When forming a treatment plan or other final goal, then you can deal with the above image to fit the program. 在有些情况下,有可能提供能够翻译这种治疗方案的软件来产生最后的影象,从而也就产生了代表最后牙齿布局的这一组数字数据集。 In some cases, it is possible to provide such a regimen capable of translation software to generate the final image and, thus, produce a final tooth arrangement of the representative set of digital data set.

按照本发明,提供了利用许多离散的器械来逐渐移动牙齿的方法和装置,其中,每一个器械以相当小的移动量逐次移动患者的一颗或多颗牙齿。 According to the present invention, there is provided a method and apparatus utilizing a plurality of discrete devices to gradually move the teeth, wherein each device with a relatively small amount of movement successively moving one or more teeth of the patient. 牙齿的移动方式是在正牙治疗中通常使用的方式,包括相对于垂直中心线的全部三个正交方向的平移,牙齿中心线在两个正牙方向(“根角”和“扭转”)的转动,以及绕着中心线的转动。 Moves teeth is the way in orthodontic treatment generally used, including with respect to translation in all three orthogonal directions perpendicular to the center line, the center line of the teeth in the two orthodontic directions ("root angle", and "twist") of the rotation, and the rotation about the centerline.

请看图1A,一个代表性的颚部100包括16颗牙齿102。 Referring to Figure 1A, a representative jaw 100 includes sixteen teeth 102. 本发明的目的是要把这些牙齿中的至少若干颗从原始牙齿布局移动到最后牙齿布局。 The object of the present invention is to at least some of these teeth in the teeth from the original layout of the mobile tooth arrangement to the final tooth. 为了说明牙齿是如何移动的,画出了一根通过牙齿102的任意的中心线(CL)。 To illustrate how the movement of the teeth, to draw the center line (CL) by any one of the teeth 102. 以这根中心线(CL)为基准,能在用轴线104、106和108(其中104是中心线)表示的三个正交方向上移动这些牙齿。 To the root center line (CL) as a reference, these teeth can be moved in three orthogonal axes 104, 106 and 108 with (where 104 is the centerline) showing a direction. 上述中心线可以绕着轴线108(根角)和104(扭转)转动,分别如箭头110和112所指示。 The center line may be around the axis 108 (root angle) and 104 (reverse) rotation, respectively, as indicated by arrows 110 and 112 instructions. 此外,牙齿还可以如箭头114所指示绕着中心线转动。 In addition, the teeth can also be indicated by arrow 114 as rotation around the centerline. 因此,能完成牙齿的所有可能的自由形式的运动。 Thus, to complete the tooth form of all the possible free movement. 现在请看图1B,用本发明的方法和装置所能达到的任何牙齿运动的幅度将以牙齿102上任何一点P的最大线性平移来确定。 Now look at Figure 1B, the maximum linear translation of magnitude by the method and apparatus of the present invention can be achieved in any tooth movement of teeth 102 at any point P will be determined. 当牙齿以图1A中的任何一个正交或旋转方向移动时,每一点Pi的平移量都要累计起来。 When the teeth in Fig. 1A any orthogonal or rotational direction, the offset of each point Pi must add up. 即,虽然一般情况下这一点将循着一条非线性路径移动,但在治疗过程的任何两个时间确定牙齿布局时,在牙齿的任何点之间都会有一个线性距离。 That is, although under normal circumstances as will follow a non-linear path to move, but the layout of the teeth is determined at any two times during the treatment, and at any point between the teeth will have a linear distance. 因此,任意一点Pi可能在事实上作如箭头d1所示的真正的左右平移时,另一个任意的一点P2可能沿着一条弧线移动,其造成的最终平移为d2。 Thus, at any point Pi is in fact possible to make as shown by the arrow d1 in real pan around, another arbitrary point P2 may move along an arc, which is caused by a final translation d2. 本发明的许多情况要由在任何特定的牙齿上用本方法所引起的一点Pi的最大容许移动量来确定。 Many of the present invention is to be determined by the maximum permissible amount of movement in any particular tooth caused by the present process point of Pi. 这种最大牙齿移动量又由牙齿上点Pi的最大线性平移量来确定,该点Pi在该牙齿的任何一个治疗步骤中经受最大移动量。 This volume is the largest tooth movement is determined by the maximum amount of points Pi linear translation of the teeth, the point Pi to withstand the maximum amount of movement in any one treatment step in the tooth.

请看图1C,按照本发明的系统包括许多逐渐调节位置的器械。 Referring to Figure 1C, the system according to the present invention comprises a plurality of gradually adjusting the position of the instrument. 这种器械能用以上所描述的方法逐渐使颚部上各个牙齿重新定位。 This instrument can be used the method described above so that the jaw portion is gradually reposition individual teeth. 广义的说,本发明的方法能使用任何公知的定位器、保持器,或者任何其他可移动的器械,这些器械都是普通的正牙治疗中为修正和保持牙齿布局所公知的。 Broadly speaking, the method of the invention can be used any known positioners, retainers, or any other movable devices, these devices are conventional orthodontic treatment for correcting and maintaining the tooth arrangement is well known. 本发明的系统与现有技术中的设备和系统相反,它将提供许多要由患者逐次戴上的器械,以便达到以上所述的逐渐重新定位牙齿布局的目的。 System of the present invention and the prior art devices and systems Instead, it provides a number of successive wear by the patient to the instrument in order to achieve the above object gradually repositioning teeth layout. 一种优选的器械100包括一个具有一空腔的聚合物外壳,该空腔的形状能容纳牙齿,并以弹性的方式使牙齿从一个牙齿布局重新定位到下一个牙齿布局上。 A preferred instrument 100 comprises a polymeric shell having a cavity, the cavity can accommodate the shape of the teeth, and the teeth in a resilient manner from one tooth to the next layout repositioning a tooth layout. 通常,但不是必须,这种聚合物外壳能套在上下颚部的所有牙齿上。 Typically, but not necessarily, the polymer shell can be fitted over all the teeth on the lower jaw portion. 常常是只有一颗或几颗牙齿要重新定位,而其他的牙齿都是为在重新定位的器械对将要重新定位的牙齿施加弹性的重新定位力时,为它提供固定用的基础。 Often only one or a few teeth to be repositioned, and the other teeth are repositioned for the instrument to be applied to reposition the teeth resilient repositioning force, provide a basis for fixing it. 但是,在情况复杂时,在治疗过程中有许多或者大多数牙齿要重新定位到某个点上。 However, in the case of complex, in the course of treatment many or most of the teeth to be repositioned to a certain point. 这时,被移动的牙齿也能够起固定重新定位的器械的基础的作用。 At this time, the teeth can be moved from the fixed base of the repositioning device role. 此外,齿龈和/或底板也能够起固定部位的作用,因此,能让所有的或几乎所有的牙齿都同时重新定位。 Furthermore, gums and / or the bottom plate can also function as a fixed portion, therefore, allowing all or nearly all of the teeth are simultaneously repositioned.

图1C中的聚合物器械100通常是用一种合适的合成橡胶聚合物的薄板形成的,例如Tru-Tain的0.03英寸的热成形牙科材料,明尼苏达州55902,Rochster市的Tru-Tain塑料。 Figure 1C instrument 100 is typically a polymer sheet with a suitable synthetic rubber polymer is formed, for example, 0.03 inches thermal Tru-Tain forming dental material, Minnesota 55902, Tru-Tain Plastics Rochster city. 一般为了在牙齿上固定这种器械,不需要钢丝或其他手段。 Usually such a device in order to fix, no wires or other means on the tooth. 但,在有些情况下,就需要或必须在牙齿上设置单独的紧固件,并且在器械100上要有相应的插孔,这样器械才能够对牙齿施加向上的力,但如果没有这种紧固件,就将无法施加。 However, in some cases, it is desirable or necessary to set separate fasteners on the teeth, and have a corresponding jack on the instrument 100 so that the instrument was capable of applying an upward force on the teeth, but if no such tight firmware, it will not be applied. 下面,描述制造这种器械100的具体方法。 Next, a specific method of manufacturing such a device 100 will be described.

请参阅图2,下面将描述本发明用于制造逐渐调节位置的器械的整个方法,患者用这种器械来使患者的牙齿重新定位。 See Figure 2, the entire process of the present invention for manufacturing gradually adjusting the position of the instrument will be described below, the patient using this instrument to reposition the patient's teeth. 第一步,获得代表原始牙齿布局的一组数字数据集,以下称之为IDDS。 The first step for the representation of the original layout of a set of teeth, digital data sets, hereinafter referred to as IDDS. 这种IDDS可用各种不同的方式获得。 This can be used in various ways IDDS obtained. 例如,可以对患者的牙齿进行扫描,或者使用公知的技术进行造影,诸如X射线,立体X射线造影,计算机辅助的层析X射线摄影法,或者数据集、磁共振造影法等等。 For example, the patient's teeth may be scanned, using well known techniques or angiography, such as X-rays, three-dimensional X-ray imaging, computer-aided tomography X-ray photography method, or data sets, magnetic resonance angiography method and the like. 把这种普通的影象数字化以产生在本发明中使用的数据集的方法是公知的,公开在专利和医学文献中。 To such a conventional digital image to generate data sets for use in the present invention, a method is known, as disclosed in the patent and medical literature. 但是,本发明常常依赖公知的技术来首先获得患者牙齿的石膏铸件,例如格拉勃(Graber)公开的“正牙学:原理与实践”,1969年,第二版,401-415页,费城,桑德斯。 However, the present invention is often rely on well-known techniques to first obtain the patient's dental plaster castings, such as Gela Bo (Graber) open "Orthodontics: Principles and Practice", 1969, second edition, pages 401-415, Philadelphia, Sanders. 获得牙齿铸件之后,就能够用普通的激光扫描器或者其他测距装置进行数字扫描来产生IDDS。 After obtaining the dental castings, can be digitally scanned using a laser scanner or other conventional distance measuring means to produce IDDS. 当然,由测距装置所产生的数据集可以转换成与用于处理该数据集范围内的影象的软件相兼容的其他格式,这一点还要在下面详细说明。 Of course, generated by the ranging unit data set may be converted into another format for processing the image with software within the dataset extent compatible, which is also described in detail below. 一般用于制造牙齿的石膏铸件的技术,和利用激光扫描技术产生数字模型的技术,公开在诸如美国专利No.5,605,459中,该文献的全部内容都可作为本申请的参考。 Generally used in the manufacture of dental plaster casting techniques, and the use of laser scanning technique to generate a digital model of the technology, such as disclosed in U.S. Patent No.5,605,459, the entire contents of which is incorporated by reference in the present application are available.

测距装置有很多种类,通常根据测距过程是否需要与所测立体物体接触来分类。 There are many types ranging device, usually ranging process according to the need for contact with the measured three-dimensional objects to classify. 接触式测距装置利用一个具有多级平移和/或旋转自由度的测头。 A contactless measuring device with the use of a multi-stage translation and / or rotational degrees of freedom of the probe. 借助于记录测头在扫过样品表面时的实际位移,就能得到一个目标样品的计算机可读表示。 Recording means when the actual displacement of the probe sweeps the sample surface, the sample can be obtained a target computer readable representation. 非接触式测距装置或者是一种反射式的,或者是一种透射式的装置。 A contactless measuring device, or a reflective or a transmissive device. 正在使用的有各种各样的反射装置,其中的一些是利用非光学的入射能源,例如微波雷达或声纳。 There are various reflecting means being used, some of which is the use of non-optical incident energy sources such as microwave radar or sonar. 其他的则利用光能。 Others are utilizing light energy. 那些靠反射的光能工作的非接触式装置还装有专门的仪器,这种仪器设计成能完成一定的测量技术(例如影象的无线电定位,三角测量和干涉测量)。 Those working by reflected optical energy is also provided with a non-contact means of specialized equipment, this instrument is designed to be able to complete certain measurement techniques (e.g., image-based radio positioning, triangulation and interferometry).

一种优选的测距装置是光学的、反射的非接触式扫描仪。 A preferred distance measuring device is an optical, reflective, non-contact scanner. 非接触式扫描仪的优点在于其固有的无损性(即,不损坏样品目标),它的总的特征是拍摄物较高的分辨率和能在较短的时间内扫描一个样品。 Advantage of non-contact scanner is its inherent non-destructive (i.e., without damaging the sample target), it is characterized by higher overall resolution of the subject and can be scanned in a short period of time a sample. 加州,蒙特里尔的Cyberware公司制造的Cyberware15型扫描仪是其中的一种。 California, Montreal's manufactured Cyberware15 Cyberware scanner is one of them.

无论是非接触式还是接触式扫描仪,都有一个有色摄象头,它在具有扫描功能的同时能以数字格式拍摄样品物体的彩色表示。 Whether non-contact or contact scanner, there is a colored camera, it also has the scanning function can take a sample of objects in digital format color representation. 这种不仅能拍摄样品物体的形状,还能拍摄出它的颜色,其重要性将在下面说明。 This can not only capture the shape of the sample of objects, but also to capture its colors, its importance will be explained below.

在一个优选实施例中,还要从患者得到一个蜡咬印。 In one preferred embodiment, but also to give a wax bite plate from the patient. 这种蜡咬印使得能在中央咬合位置上扫描上下牙齿的相对位置。 The wax bite can be printed so that the relative position in a central position on the scanned nip the upper and lower teeth. 其实现方法是,首先把下部铸件放在扫描器的前面,并使牙齿朝上,然后把蜡咬印放在下部铸件的顶上,最后,把上部铸件放在下部铸件的顶上,牙齿朝下,搁在蜡咬印上。 This is accomplished by first casting the lower part on the front of the scanner, and the teeth facing up, and then printed on the wax bite on top of the lower portion of the casting, and finally, the upper portion of the casting of the lower part of the top of the casting, towards the teeth next, resting on the wax seal bite. 然后对处在相对位置上的上、下铸件进行圆柱形扫描。 Then in a relatively upper position, the lower cylindrical casting scan. 扫描所得的数据形成一个代表物体的中间分辨率的数字模型,其是位于和嘴里的相对位置一样的位置上的患者的拱形的组合。 The resulting scan data forming a digital model representative of object intermediate resolution, which is a combination of the patient's arch is located and the relative position of the mouth of the same position.

这种数字模型起引导上述两个单独的数字模型(每一个拱形一个)放置的样板作用。 This digital model from the boot of the two separate digital models (one for each arch) placed in the role model. 更精确的说,利用软件,例如Cyberware的对准软件,使每一个数字拱形逐次对准该成对扫描。 More precisely, using software, such as Cyberware alignment software, so that each successive digital arch alignment of the paired scan. 然后,把单个模型定位在与患者嘴里的拱形对应的相对位置上。 Then, the relative position of a single model positioned in correspondence with the arch of the mouth of the patient.

本发明的方法是依靠在具有适当的图形用户界面(GUT)和适合于观看和修改影象的软件的计算机或工作站上处理上述IDDS。 The method of the present invention is to rely on the processing described above IDDS having an appropriate graphical user interface (GUT) and the image suitable for viewing and modifying the software of the computer or workstation. 下面将详细描述这种软件的特定性能。 Specific performance of this software will be described below in detail. 虽然这种方法是依靠计算机来处理数字数据集,本发明的包括具有逐渐改变几何形状的多种牙科器械的装置可以用非计算机辅助技术来制造。 While this approach is to rely on the computer to process the digital data set, the present invention comprises a device having a plurality of gradually changing the geometry of the dental appliance may be produced by non-computer-aided techniques. 例如,用上述方式获得的石膏铸件可以用刀子、锯或者其他切削工具切开,以便能让各个牙齿在该铸件中重新定位。 For example, gypsum obtained in the manner described above can be cast with a knife, saw or other cutting tool to cut, in order to allow the respective tooth repositioning in the casting. 然后,切开的牙齿可以用软蜡或其他可熔化的材料固定,这样,利用这种经过修正的患者牙齿的石膏铸件,能够设计出许多中间牙齿布局。 Then, cut the teeth with a soft wax or other meltable material is fixed, so that, after the patient using this modified plaster casting teeth, be able to design many intermediate teeth layout. 不同的位置可以用于准备许多组器械,其一般是采用以下所描述的加压和真空模制技术。 Different positions can be used to prepare a number of groups instrument, which is typically pressurized and vacuum molding techniques described below. 虽然一般都不太愿意采用这种手工制作的器械,但是,用这种方式制作出来的装置也包括在本发明的范围内。 Although generally less willing to use such a hand-made instrument, however, produced in this way means are also included within the scope of the present invention.

请再看图2,在获得了IDDS之后,要把数字信息输入计算机或其他工作站进行处理。 Please look at Figure 2, after obtaining the IDDS, take digital information into a computer or other workstation for processing. 在这种优选的方法中,各个牙齿和其他元件将被“切开”,以便能使其单独重新定位,或者从数字数据集中去除。 In this preferred process, the individual teeth and other components will be "cut", in order to enable it to separately reposition, or remove focus from the digital data. 经过这样的元件“自由化”之后,使用者就要经常遵照专业治疗人员提供的治疗方案或其他书面说明。 After such elements "liberalization", the user must follow the treatment plan often provide professional treatment or other written instructions. 或者,使用者可以根据可视的外观或利用在计算机中编好程序的规则和算法对它们重新定位。 Alternatively, the user may reposition them based on the visual appearance or use in a computer programmed rules and algorithms. 一旦使用者对最后的位置满意了,这个最后的牙齿布局便组成一组最后的数字数据集(FDDS)。 Once users are satisfied with the final position, the final tooth arrangement will be composed of a group of final digital data set (FDDS).

根据IDDS和FDDS这两者,就能产生对应于一系列中间布局的许多中间数字数据集(INTDDS)。 According IDDS and FDDS both, and can create a series of intermediate layout corresponds to many intermediate digital data set (INTDDS).

图3表示一种用于处理上述IDDS以便在计算机上产生FDDS的有代表性的技术。 Figure 3 shows a representative technique for processing said IDDS to produce the FDDS on the computer. 一般从数字扫描仪输送来的数据是高分辨率的。 General transported from the digital scanner is a high-resolution data. 为了减少计算机为产生影象所需要的时间,要形成一组平行的以低分辨率表示IDDS的数字数据集。 In order to reduce the computer time to produce the desired image, to form a set of low resolution representation IDDS parallel digital data sets. 使用者将处理这个低分辨率的影象,而计算机则将按照需要适时更新高分辨率数据集。 Users will handle the low-resolution images, and the computer will be updated in accordance with the need for timely resolution data sets. 如果在该模型中的附加的细节是有用的,使用者还可以观看/处理这个高分辨率的模型。 If additional details of the model are useful, the user can also view / process the high resolution model. 上述IDDS还可以转换成四边数据结构,如果还没有用这种型式表现的话。 IDDS above data can also be converted into a quadrilateral structure, if not useful, then this type of performance. 四边数据结构是一种标准的拓朴数据结构,它是在1985年四月出版的ACM图解学报的第四卷第二期,74-123页中的“Primitives for theManipulation of General Subdivisions and the Computation of VoronoiDiagrams”提出来的。 Four sides of the data structure is a standard topology data structure, which is published in the April 1985 Journal of the ACM graphical fourth volume in the second period, 74-123 page "Primitives for theManipulation of General Subdivisions and the Computation of VoronoiDiagrams "initiative. 其他的拓朴数据结构,例如翼边缘数据结构也可以使用。 Other topological data structures, such as wing edge data structures may also be used.

作为一个最初的步骤,当使用者看到患者的包括牙齿、齿龈和其他口部器官的颚部的立体影象时,他一般将把那些对于影象处理和/或最后制造器械来说不需要的结构删去。 As an initial step, when the user sees the patient include teeth, gums and other mouth organs stereoscopic image jaw portion, he will generally not required for that image processing and / or manufacturing equipment for final The structure deleted. 模型上这些不需要的部分可以用一种擦除工具将其消除,以完成一种实体建模减法。 These unwanted parts of the model can be erased with a tool to eliminate it, in order to complete a solid modeling subtraction. 这种工具可由一种图形框来代表。 This tool is represented by a graphic box. 要擦除的量(尺寸、位置和框的方位)由使用者用GUI设定。 To erase amount (size, location and orientation of the frame) is set by the user using the GUI. 一般,不需要的部分包括外部的齿龈区域和原始扫描所得铸件的底部。 In general, unnecessary portions of the gingival area including the bottom of the outer and the scanned original casting. 这种工具的另一种应用是促进牙齿的拔掉,以及牙齿表面的“修整”。 Another application of such tools is to promote teeth pulled out, and a tooth surface "finishing." 当为了要移动的牙齿的最后定位需要颚部中的额外空间时,这样做是必需的。 When the last location in order to move the teeth in the jaws requires additional space, this is required. 治疗专业人员可以选择确定那些牙齿要修整和/或那些牙齿要拔掉。 Treatment of dental professionals can choose to identify those to be trimmed and / or those teeth to be pulled out. 当只需要少量空间时,修整能让患者保持他们的牙齿。 When you need only a small amount of space, dressing allows patients to maintain their teeth. 当然,一般说来,只有在按照本发明的方法开始重新定位之前,当实际患者的牙齿要拔掉和/或修整时,才在治疗方案中使用拔牙和修整。 Of course, in general, only in accordance with the method of the present invention prior to the start of repositioning, when the actual patient's teeth must be extracted and / or trimming only when using the extraction and dressing in the treatment program.

去除模型上不需要和/或不必要的部分,加快了数据处理的速度,改善了显示效果。 Unwanted and / or unnecessary removal of part of the model, accelerate the speed of data processing, improved display. 不必要的部分包括那些在制造牙齿重新定位器械时不需要的部分。 Include those unnecessary parts in the manufacture of tooth repositioning devices unnecessary portions. 去除这些不需要的部分减少了数字数据集的复杂性和大小,从而加速了数据集的处理和其他操作。 Removal of these unnecessary portions reduces the complexity and size of the digital data set, thus accelerating the processing of the data set and other operations.

在使用者定位好擦除工具并规定了它的大小,并且指令软件把不需要的部分擦除之后,由使用者设定的框内的所有的三角形都要被除掉,而要对边缘上的三角形进行修正,以得到平滑的直线边界。 The users location and provides a good tool to erase its size, and instruction software to erase unwanted parts after all the triangles set by the user box must be removed, and to the edge triangle is corrected to obtain a smooth straight boundary. 上述软件删除了框内部所有的三角形,并且剪裁与框的边界交叉的所有三角形。 Above software deletes all the triangles inside the box, and all cross border triangle cut and frame. 这需要在框的边界上产生新的顶点。 This requires generating new vertices on the boundary of the box. 在模型上,在框表面上形成的孔要重新组成三角形,并利用新形成的顶点将其封闭。 In the model, the hole in the frame to be re-formed on the surface composition of the triangle, using the vertices newly formed to be closed.

上述锯切工具用于确定要移动的各个牙齿(或者也可能是成组牙齿)的轮廓。 Means for determining the contours of the cutting tool to move the respective teeth (or possibly groups of teeth) of. 这种工具将扫描所得的影象分成单独的图形分量,使得软件能移动这颗牙齿或其他影象分量,而不影响模型上的其余部分。 This tool scans the image into individual graphic components, so that the software can move the tooth or other component of the image, without affecting the rest of the model. 在一个实施例中,这种锯切工具确定了一条用两条放在空间的三次B样条曲线(有可能限制在平行的平面内,或者敞开的,或者封闭的)来切割图像的路径。 In one embodiment, the cutting tool in determining a space with two cubic B-spline curve (there may be limited in the parallel planes, or open or closed) to cut the image path. 一组线条把这两条曲线连接起来,并向使用者显示出总的切割路径。 A set of lines connecting these two curves up to the user to display the total cutting path. 使用者可以编辑在三次B样条上的控制点,锯切厚度,以及所用的擦除器的数量。 Users can edit the cubic B-spline control points, the number of cutting thickness and eraser used. 这些将在下面说明。 These will be described below.

在另一个优选实施例中,用锯作为一种“核心”装置,从上方以垂直的锯切来分开牙齿。 In another preferred embodiment, with a saw as a "core" device, from above to separate the vertical sawing teeth. 牙齿的齿冠,还有紧靠齿冠下方的齿龈组织从这种几何形状的其余部分分离开来,并作为称为牙齿的一个单独的单元来处理。 Tooth crown, as well as close to the bottom of the gingival tissue of the crown from the rest of the geometry of this separated, and as a single unit known as teeth to handle. 当这个模型移动时,齿龈组织便相对于齿冠移动,形成在患者的口内改造齿龈的途径上的第一级近似值。 When this model is moved, gingival tissue will move relative to the crown, forming a first level approximation pathway within a patient's mouth on the transformation of the gingiva.

也可以把每一颗牙齿从原始修正后的模型上分离开来。 You can also put each tooth from the model of the original amended separated. 此外,可以通过切掉牙齿的齿冠,从原始修正后的模型制造出一块底板。 Further, by cutting off the tooth crown, from the original model is modified to produce a piece of the bottom plate. 所得模型可以用作移动牙齿的底板。 The resulting model can be used to move the teeth of the floor. 这样方便了从上述几何模型制造出最终实体模型来,这还要在下面说明。 So convenient to create a geometric model from the end-entity model, which also described below.

厚度:当用一个切口把一颗牙齿分开时,使用者通常希望切口尽可能的薄。 Thickness: When the tooth with a separate incision, users often want to incision as thin as possible. 但是,使用者也许需要较厚的切口,例如,在下面说到的修整周围的牙齿时。 However, the user may need thicker incision, for example, when it comes in the following dressing around the teeth. 在图像上,这个切口好象一条曲线,在曲线的一侧以切口的厚度为界。 On the image, the incision as if a curve, the curve on one side is bounded by a thickness incision.

擦除器的数量:一个切口包括许多一个挨一个排列的擦除器框,好象锯切工具曲线路径的分段线性近似。 Erase the number: a cut, including many arranged next to one another eraser box, as if sawing tools piecewise linear approximation of a curved path. 使用者选择擦除器的数量,这决定了所形成的曲线的完善程度,即,分段的数量越多,随着曲线的切割就越精确。 Users select the eraser number, which determines the degree of perfection of the formation of the curve, that is, the more the number of segments, with the cut, the more accurate the curve. 擦除器的数量以图像的方式用连接上述两条三次B样条曲线的平行线的数量来表示。 The number of the number of erase the image of the way by connecting the two cubic B-spline curve parallel lines to represent. 一旦锯切切口完全确定,使用者就可以在模型上加上这个切口。 Once the cut sawing fully established, the user can add the incision on the model. 这个切口是以逐次的擦除来完成的。 This incision is done successive erasure. 图4A中列出了一种常用的算法。 Figure 4A shows the a common algorithm. 图4B表示上述切口在用于开端B样条曲线的算法中描述的单个擦除累积法。 Figure 4B shows a single algorithm for the cut in the beginning of the B-spline curve described erase the cumulative method. 对于一条垂直的切口来说,这两条曲线是用PA[O]和PA[S]相同的点来封闭的,而PB[O]和PB[S]是相同的点。 For a vertical incision, the two curves with PA [O] and PA [S] the same point to be closed, and PB [O] and PB [S] are the same point.

在一个实施例中,软件会自动根据使用者输入的平滑度的程度把锯切工具隔成一组擦除器。 In one embodiment, the software will automatically enter the user according to the degree of smoothness of the cutting tool was divided into a set of erasers. 锯切还能够再细分,直到误差度量计测量出从理想的图像到近似的图像的偏差小于由设定的平滑度所规定的阈值。 Sawing can also be subdivided until the error metric measured from the ideal image to approximate deviation from smoothness of the image is smaller than the predetermined set threshold value. 通常使用的误差度量计是把细分的曲线的线性长度与理想的样条曲线的弧长相比较。 Error metric commonly used gauge is the arc length segments of the curve and the ideal linear spline compared. 当差别大于从设定的平滑度计算出来的阈值时,便沿着这条样条曲线增加细分点。 When the difference is greater than the set from the smoothness of the calculated threshold, then along this spline subdivision point increase.

还可以在上述软件上设置预显功能。 Pre-display function can also be set on the software. 这种预显功能以可视的方式以代表切口的相对两侧的两个表面显示出一条锯切的切口。 This pre-display function manner to represent visually the two surfaces on opposite sides of the incision shows a sawn incision. 这样,就能让使用者在对模型的数据集加上切口之前考虑最后的切口。 In this way, users will be able to make the data set prior to consideration of the final model plus incision incision.

在使用者已经用上述锯切工具完成了全部需要做的切割工作之后,存在着许多图像实体。 After the user has finished with the above sawing tools needed to do all the cutting work, there are many images entities. 但是,此时软件还没有确定哪一些四角边缘数据结构的三角形是属于哪一些分量的。 However, at this time the software has not determined which of the four corners of the triangular edge data structure belong to which of a number of components. 软件在数据结构中选择一个随机的开始点,并利用邻接的信息遍历这个数据结构,来找到所有互相连接的三角形,确定一个单独的成分。 Software chooses a random starting point in the data structure, and the use of adjacent traverse the data structure information, to find all interconnected triangles, to determine a separate component. 这个过程从分量还没有确定的三角形开始,反复进行。 This process is not yet determined from the weight of the triangle start, repeatedly. 一旦遍历了整个数据结构,所有的分量也就确定了。 Once the entire data structure traversal, all components also determined.

对于使用者来说,对高分辨率模型所作的改变似乎同时就在低分辨率的模型中发生了,反之亦然。 For users, the high-resolution model changes made to seem simultaneously took place in low-resolution model, and vice versa. 但是,在不同分辨率的模型之间并不是一对一的关系。 However, between the different resolution models is not one to one relationship. 因此,计算机尽可能使高分辨率与低分辨率的成分“匹配”在它能够做到的限度内。 Therefore, as far as possible to make high-resolution and low-resolution computer components "match" to the extent that it can be done. 这种算法示于图5。 This algorithm is shown in Fig.

齿尖的检测:在一个优选实施例中,软件具有检测牙齿齿尖的能力。 Prong detection: In a preferred embodiment, the software has the ability to detect tooth prongs. 齿尖是凸出在牙齿的咀嚼表面上的尖顶。 Protruding prongs are on the chewing surfaces of the teeth of the spire. 齿尖的检测可以在切割阶段完成之前,也可以在完成之后。 Tooth tip can be detected before cutting phase is completed, you can after the completion. 用于齿尖检测的算法包括两个阶段:(1)“检测”阶段,在该阶段中,确定牙齿上的一组点作为齿尖位置的候选点;(2)“剔除”阶段,在这个阶段中,从这一组候选点中剔除那些不满足齿尖所要求的一组标准的候选点。 Algorithm for detecting the tooth tip consists of two phases: (1) "detection" stage, in this stage, to determine a set of points on the teeth as the tooth edge position of the candidate point; (2) "removed" stage, in this phase, excluding those that do not satisfy a set of criteria required prongs candidate points from the set of candidate points.

图6A中列出了“检测”阶段所常用的算法。 Figure 6A shows the "detection" stage of the algorithms used. 在这种检测阶段中,把可能的齿尖看作在牙齿表面上的一个“岛”,而候选的齿尖在这个岛上的最高点。 In this detection phase, the prongs may be viewed on the tooth surface of an "island", and the highest point of the tooth tip candidate on the island. “最高”是相对于模型的坐标系统来测量的,但是,如果检测是在治疗的切割阶段之后完成的,也可以比较容易地相对于每一颗牙齿的局部坐标系统来测量。 "Highest" is relative to the coordinate system of the model measured, however, if it is detected after the cutting phase of treatment is completed, may be relatively easily with respect to the local coordinate system of each tooth is measured.

一组全部有可能的齿尖是通过在牙齿模型上寻找所有的局部最大值来确定的,这些最大值在模型的界限框顶部一个特定的距离之内。 A set of all possible prongs on the dental model by looking for all local maxima determined, these maximum values in the box at the top limits of the model within a specific distance. 首先,将模型上的最高点指定为第一候选齿尖。 First, the highest point on the model designated as the first candidate for tips. 一个平面通过这一点,垂直于测量出一点的高度的方向。 A plane passing through this point, perpendicular to the measuring point in the height direction. 然后将这个平面沿着Z轴线降低一个预定的很小的距离。 This plane is then lowered along the Z-axis by a predetermined small distance. 接着,所有的与这颗牙齿连接的顶点,以及那些高于上述平面并且在一些连接起来的成分上的顶点,都和上述候选齿尖一起作为齿尖。 Then, with all vertices connected to the tooth, as well as those above the apex on the plane and some elements connected together, have sharp teeth and said candidate together as tips. 这个步骤也称为“溢出填充”步骤。 This step is also called "overflow fill" step. 在每一个在这个步骤中访问过的模型的顶点做上记号,作为相应的候选齿尖的“一部分”,就能够根据每一个候选的齿尖点完成向外的“溢出”。 In each vertex in this step had access model cook mark, as the respective candidate prongs of "part", it is possible to complete the outwardly "Overflow" According to each of the candidate points of the prongs. 完成了溢出填充步骤之后,校验模型上的每一个顶点。 After completing the overflow filling step, each vertex on the model validation. 任何高于上述平面,并且还没有被上述一次溢出填充访问过的顶点都加在候选齿尖的表中。 Anything above the plane, and the above-mentioned time-out has not yet been filled visited vertices are added to the tooth tip in the candidate table. 重复进行这些步骤,直到上述平面移动规定的距离。 These steps are repeated, moving distance until said predetermined plane.

虽然这种反复的寻找方法可能要比寻找局部最大值花费更多的时间,但是这种方法却能导致候选齿尖的表比较短。 While this method may be repeated to find the local maxima than looking to spend more time, but this method was able to cause the prongs of the candidate table is relatively short. 由于上述平面在每一个步骤中只降低有限的距离,所以由于噪声数据而可能发生的很小的局部最大值都被跳过去了。 Since each step in said plane to reduce only a limited distance, so that a very small local maxima that may occur due to noisy data are skipped over.

在“检测”阶段之后,齿尖检测算法进行“剔除”阶段。 After the "detection" stage, the prongs detection algorithm "removed" stage. “剔除”阶段常用的算法示于图6B中。 "Excluding" stage common algorithm is shown in Figure 6B. 在这个阶段,分析围绕着每一个齿尖候选点的局部几何形状,以确定它们是否拥有“不象齿尖的特征”。 At this stage, the local analysis around each prong geometry candidate points, to determine whether they have a "do not like prongs characteristic." 从齿尖候选点的表中去除那些表现出“不象齿尖的特征”的齿尖候选点。 Removing those exhibiting "Unlike prong characteristic" prongs candidate points from Table prong candidate point.

可用作确定“不象齿尖的特征”的准则有很多。 Can be used to determine the "tip of the tooth is not as feature" There are a lot of criteria. 按照一种测试,围绕着齿尖候选点的表面的局部弧度可用来确定该候选点是否拥有不象齿尖的特征。 According to one test, the local curvature of the surface around the tooth edge candidate points used to determine whether the candidate point has not like prongs characteristics. 如图6B所示,在大致确定了围绕着齿尖候选点的局部弧度之后,分析并确定它是否太大(非常尖的表面)或者太小(非常平坦的表面),在后一种情况下,就从齿尖候选点的表中去除这个候选点。 6B, substantially determined after partial radian around prongs candidate points, analyze and determine if it is too large (pointy surface) or too small (very flat surface), in the latter case , to remove the candidate points from the table prong candidate point. 对于这种最大和最小的弧度值要使用保守值,以保证不会因为差错而剔除真正的齿尖。 For this the maximum and minimum values of the arc to use conservative values in order to ensure that no errors while striking out as a real tooth tip.

按照另一种测试,根据围绕着这个齿尖候选点的一个区域内的平均法向计算出平滑的量度。 According to another test, the average method around this prong candidate points within a region to calculate a measure of smoothness. 如果这个平均法向偏离该齿尖的法向而超出规定的量,就剔除这个候选齿尖。 If the average normal deviates from the normal to the tooth tip and beyond the prescribed amount, to reject this candidate tips. 在一个优选实施例中,法向矢量N偏离齿尖法向CN的值用下式来估算:1-Abs(N*CN)当没有偏离时,这个值是零,当N垂直CN时,这个值是1。 In one preferred embodiment, the normal vector N normal values deviate prongs CN estimated by the following formula: 1-Abs (N * CN) when there is no deviation from this value is zero when N vertical CN when the value is 1.

一旦被分离开来之后,就能从IDDS形成FDDS。 Once they are separated, the FDDS can be formed from the IDDS. 上述FDDS是按照正牙医生的把牙齿移动到最后位置的治疗方案形成的。 In accordance with the above FDDS orthodontist's treatment plan to move to the final tooth position of formation. 在一个实施例中,把这种治疗方案输入计算机,计算机便按照算法计算牙齿的最后位置。 In one embodiment, the regimen is entered into the computer, the computer in accordance with the algorithm computing the final position of the teeth. 在另一个实施例中,使用者可以在满足治疗方案的限制下独立地处理一个或几个牙齿,使这些牙齿移动到它们最后位置上。 In another embodiment, the user may independently handle one or several teeth to satisfy the constraints in a treatment regimen, so that these teeth are moved to their final positions. 应该理解,以上所描述的技术的各种组合也可以用来达到最后的牙齿布局。 It should be understood that various combinations of the above described techniques may also be used to achieve the final tooth arrangement.

用于形成FDDS的优选方法在于使牙齿按照规定的逐次移动。 A preferred method for forming the FDDS is in accordance with the successive teeth move. 首先,使每一颗牙齿的中心对准一个标准的拱形。 First, the center of each tooth alignment of a standard arch. 然后,转动牙齿,一直到让牙根处于合适的垂直位置上。 Then, rotation of the teeth, so that until the root is in the proper vertical position. 然后沿其垂直轴将牙齿旋转至合适的方向。 Then the teeth along its vertical axis of rotation to the right direction. 然后,从侧面观察牙齿,并沿垂直方向将其平移到合适的垂直位置。 Then, the teeth viewed from the side, and it is translated to the proper vertical position along the vertical direction. 最后,把两个拱形放在一起,并稍微移动牙齿,以保证上下拱形正确地啮合在一起。 Finally, the two arch together, and slightly move the teeth to ensure that the upper and lower arch mesh together properly. 上下拱形的啮合可利用冲突检测算法来显示,用红色来突出牙齿的接触点。 Engaging the upper and lower arch of the conflict detection algorithm can be used to display, red to highlight the contact points of the teeth.

在牙齿和其他成分已经安置好或去除掉之后,就能产生出最后的牙齿布局,如图7所示,这时必须制订一个治疗计划。 In the teeth and other components have been properly placed or removed after the teeth will be able to produce a final layout, as shown in Figure 7, when the need to develop a treatment plan. 如上所述,这个治疗计划将最终产生一系列INTDDS和FDDS。 As mentioned above, the treatment plan will ultimately produce a series INTDDS and FDDS. 为了产生这些数据集,必须确定或规划出所选定的各个牙齿从原来的位置通过一系列逐次的步骤向最后的位置的移动。 In order to generate these data sets must be determined or selected plan out each tooth from its original position by moving a series of successive steps in the last position. 此外,为了在这个治疗方案中形成所要求的特点,还必须在这些数据集中增加其它特征。 In addition, the required characteristics in order to be formed in this treatment, it is also necessary to add other features to focus on these data. 例如,为了形成用于特殊目的的空腔或凹槽,可能需要在图像上增加蜡制补丁。 For example, in order to form a cavity or recess for a particular purpose, may need to increase the wax patch on the image. 例如,可能需要在器械与牙齿或颚部的特定区域之间保持一个空间,以便减小齿龈的疼痛,避免周期性的问题,容许戴上罩子,等等。 For example, it may be necessary between the instrument and the tooth or jaw portion of a particular area of a holding space, in order to reduce pain in the gums, avoid periodic problem, allowed to wear the cap, and so on. 此外,可能常常需要提供一个用于容纳紧固件的插孔或小孔,这种紧固件是用于安放在一颗牙齿上,以便牙齿能用这个紧固件来处理,例如相对于颚部向上提高。 In addition, it may often desirable to provide a receptacle for receiving a fastener or pores, such fasteners are used mounted on a tooth so that the teeth can be used to handle the fasteners, e.g., with respect to the jaw Ministry raise upwards.

有些制造牙齿重新定位的器械的方法要求分开的重新定位的牙齿和其他部分统一在一个单一的连续的构件中,以便进行制造。 Some of the methods of manufacturing the tooth repositioning devices require separate repositioning teeth and other parts united in a single continuous member, to be manufactured. 在此情况下,可使用“蜡制补丁”来固定上述INTDDS的否则会断开的部分。 In this case, use the "wax patches" will break the fixed portion of said INTDDS. 这些补丁加在牙齿下方和齿龈上方的数据集上,于是它们就不会影响牙齿重新定位的器械的几何形状。 These patches applied to the bottom of the upper teeth and gums data sets, so that they do not affect the geometry of the tooth repositioning instrument. 应用软件为在模型上增加蜡制补丁提供了多样性,包括具有可调尺寸的框和球形。 To increase the wax application software patches on the model provides diversity, including frame with adjustable size and spherical. 上述加上去的蜡制补丁由软件处理为与所有其他几何形状一样的几何形状附加成分。 Above plus go wax processed by software patch for all other geometric shapes like geometry additional ingredients. 因此,这种蜡制补丁能在处理路径上和牙齿及其他成分一样重新定位。 Thus, the wax patches can be manufactured and teeth, and other ingredients as repositioned on the processing path. 如上所述,这种优选的利用垂直核心分离牙齿的方法去除了对大多数“蜡制补丁”的需要。 As described above, with a vertical core of this method of separation of the teeth preferably removes most "wax patches" needs.

在上述依靠产生正模型来制成重新定位的器械的制造过程中,在图像模型中加入蜡制补丁将产生一个具有同样的加入蜡制补丁的几何形状的正模具。 In the manufacturing process is made by generation of positive models to reposition the instrument as described above, was added wax patch in the image model will generate a positive mold having the same added wax patch geometry. 因为这种模具是牙齿的正性,而上述器械则是牙齿的负性,当这种器械在上述模具上形成时,它将也能在加入这个模具的蜡制补丁的周围形成。 This is because the teeth of the positive mold, and said device is a negative of the teeth, when such a device is formed on the mold, it will also be added to the mold around the wax patch formation. 当把器械放入患者的口内时,这种器械就会在该器械的内空腔表面与患者的牙齿或齿龈之间让出一个空间来。 When the instrument into the mouth of the patient, this instrument will be in the cavity between the inner surface of the instrument with the patient's teeth or gums let out a space. 此外,这种蜡制补丁还可以用于在该器械内部形成一个与放入口内的紧固件配合的凹槽或孔,以便使牙齿向各方向移动,要不然就做不到这一点。 In addition, such wax patches may also be used in the device formed inside a recess or hole into the mouth of the mating fastener, so that the teeth move in all directions, or else can not do this.

在这种蜡制补丁之外,单独的一个元件,通常是一颗牙齿,还可以按照比例放大或缩小尺寸,这样,所制成的器械就能相应地具有较紧或较松的配合。 In addition to such wax patches, an individual component, usually a tooth, can also be scaled up or down according to the size, so that the instrument can be made of correspondingly having tight or loose fit.

治疗计划在确定牙齿和其他元件的移动方面是非常灵活的。 Determining a treatment plan in the teeth and other components of the mobile aspect is very flexible. 使用者可以改变治疗阶段的数量,并且可以个别控制元件的路径和速度。 The user can change the number of treatment stages, and can control the path and speed of the individual components.

治疗阶段的数量:使用者可以改变牙齿从原始状态到目标状态所需要的治疗阶段的数量。 Number of stages of treatment: the user can change the number of teeth from the original state to the target state needed treatment phase. 任何不移动的元件都被认为是固定不动的,因此,假定它的最后位置和它的原始位置相同(对于所有的中间布局也同样,除非为那个元件确定了一个或多个主框)。 Any non-moving elements are considered to be stationary, therefore, assumed its final position to its original position and the same (for all intermediate layout also, unless it is determined that one or more of the main frame of the element).

关键框架:使用者还可以通过选定一个中间状态和对元件的位置进行改变来规定“关键框架”。 Key Frame: The user can also be specified "key frame" by selecting an intermediate state and position of the component changes. 除非另有指令,软件将自动地在所有使用者规定的位置(包括原始位置,全部关键框架位置和目标位置)之间进行线性内插。 Unless otherwise directs, the software will automatically position the provisions of all users (including the original location, all key frame position and target position) between the linear interpolation. 例如,如果为一个特定的元件仅确定了一个最后的位置,那么在原始阶段之后的每一个后续的阶段将只显示该元件一个逐渐靠近最后位置的等量的线性距离和转动(由一个四元数规定)。 For example, if a particular component only identified a final position, then each subsequent stage after the original phase will display only the last element of a gradually close the position and rotation of the linear distance equal amounts (by a quaternion several provisions). 如果使用者为该元件规定了两个关键框架,这个元件将从原始位置通过不同的阶段线性“移动”到由第一关键框架所确定的位置。 If the user specifies two key frame for the element, this element from the original position through different stages of linear "move" to a key frame by the first determined location. 然后,该元件有可能以不同的方向线性移动到由第二关键框架所确定的位置上。 Then, the element is likely to move linearly in different directions by the second key frame to the determined position. 最后,该元件有可能以又一个不同的方向线性移动到目标位置。 Finally, it is possible to turn the member in a different direction linearly moving to the target position.

使用者也可以在各关键框架之间规定非线性的内插。 Users may be provided between each key frame of a predetermined non-linear interpolation. 采用一条样条曲线以常规的方式来规定上述内插函数。 Using a spline curve in a conventional manner to the provisions of the above interpolation function.

以上这些操作对于每一个元件可以独立地进行,所以,对于某一个元件的关键框架将不会影响另一个元件,除非这另一个元件也被使用者规定在那个关键框架中移动。 These operations for each element can independently, therefore, the key frame for one component will not affect another component, unless the other component is also defined in the user moves the key frame. 一个元件可以沿着一条曲线在阶段3和阶段8之间加速移动,而另一个元件却从阶段1到阶段5作线性移动,并且之后突然改变方向,沿着一条线性路径缓慢地移动到阶段10。 A member can be moved along a curve in the acceleration phase 3 and phase between 8 and another element never Phase 1 to Phase 5 for linear movement, and then suddenly change direction, moving slowly along a linear path to stage 10 . 这种灵活性对于计划一个患者的治疗方案给予了很大的自由度。 This flexibility to plan a patient's treatment plan to give a lot of freedom.

在一个实施例中,软件自动地根据上述IDDS和FDDS确定治疗路径。 In one embodiment, the software automatically determines the treatment path based on the IDDS and the FDDS. 这通常是利用一种确定各元件,即一颗牙齿,沿着一条直线的路径从原始位置移动到最后位置的速率的安排路径的算法来实现的。 This is typically determined using a respective element, i.e. a tooth, arranged along a straight line path to a path of movement from the original position to the final position of the rate algorithm to achieve. 本发明所使用的这种安排路径的算法在确定处理路径的同时还避免了“兜圈子”,这是正牙医生对让牙齿沿着一条比矫正牙齿所绝对必须的距离更长的距离移动所用的术语。 This arrangement path of the present invention is used in the algorithm to determine the processing path, while also avoiding the "circle", which is the orthodontist to make teeth straightening teeth along a more than absolutely necessary to move a distance longer term used . 这种移动是非常不希望发生的,对患者有潜在的负面影响。 This movement is very undesirable, there is the potential negative impact on the patient. 为了避免“兜圈子”,上述安排路径的算法对所有牙齿的移动,通过限制它们在原始位置与最后位置之间的最短直线路径,按阶段排出逐次,同时还避免了各个牙齿之间的所有干涉。 In order to avoid the "circle", the above-described arrangement path algorithm to move all the teeth, by limiting their shortest straight path between the original position and the final position, is discharged by successive stages, while also avoiding any interference between the respective teeth.

这种安排路径的算法利用一种随机搜索技术,去找到一条通过一个构位空间的无障碍路径,这条路径描述了可能的治疗计划。 With this arrangement the path algorithm a random search, to find a path through the barrier a bit of space structure, which describes the possible paths treatment plan. 下面描述用于安排两个使用者确定的总的关键框架之间的移动的算法的优选实施例。 The following description of the preferred arrangement for moving the general algorithm of the key frame between two user specifying embodiments. 安排一段包括中间关键框架的时间段是这样来完成的:把时间段分成不包括中间关键框架的分时间段,独立地安排这些时间段,然后把所得到的这些安排串联起来。 Including arrangements for some time in the middle of the key frame is done: the time period is divided into sub-periods do not include the key intermediate frame independently arrange these time periods, and then put these arrangements in series obtained.

图8A中的流程图120表示一种按照本发明的一个实施例的简化了的安排路径的算法。 Figure 8A is a flowchart 120 showing a simplified arrangement path in accordance with an embodiment of the present invention is an algorithm. 如图8A所示,第一步骤122涉及“构位空间”描述的结构。 8A, first step 122 involves "configuration bit structure" described. 在本文中,“构位”指的是所有考虑要移动的牙齿的一组给定的位置。 As used herein, "configuration bits" refers to a given set of positions of all the teeth to be moved to consider. 这些位置中的每一个位置可以通过许多途径来描述。 Each of these positions can be described by the position of a number of ways. 在本发明的一个优选实施例中,位置是用一颗牙齿从其原始位置到最后位置的,规定位置上的改变的一个仿射变换和规定方向改变的一个旋转变换来描述的。 In a preferred embodiment of the present invention, the position is a tooth from its original position to the final position, a position of a predetermined change in a predetermined direction of affine transformation and changes a rotational transformation described. 每一颗牙齿的中间布局用一对数字来描述,这对数字规定在两个端点之间内插的位置和方向的位置。 Intermediate layout of each tooth with a pair of numbers to describe the location of which is specified in the figures between the two endpoints of the interpolation position and orientation. 因此,对于每一个要移动的牙齿来说,一个“构位”由两个数字组成,而“构位空间”是指所有这种数字对的空间。 Thus, for each tooth to be moved, one "configuration bits" consist of two digits, and the "configuration bit space" means the space of all such number pairs. 因此,这种位空间是一种笛卡尔空间,其中的任何位置能够转换成对所有牙齿布局的规定。 Therefore, this is a bit of space Cartesian space, any position which can translate into requiring all teeth layout.

描述每一颗牙齿从其开始位置到终端位置的运动的仿射变换可以分解成平移分量和旋转分量;这些变换是独立地用无矢量参数内插的,这些参数考虑了上述构位空间的二维。 Description of each tooth from its starting position to the end position of the movement of the affine transformation can be decomposed into a translational component and a rotational component; these transformations are independently interpolated with the parameters of the non-vector, these parameters in mind the above configuration space of two bits dimension. 因此,整个构位空间由每一颗移动牙齿的二维所组成,所有这些在随后的搜索过程中都同等对待。 Thus, the entire structure every bit of space from a two-dimensional movement of the teeth, all of which are treated equally in the subsequent search process.

上述构位空间是由“自由空间”和“障碍空间”组成的。 Configuration space is a bit above the "free space" and "obstacles space" composed. “自由”构位是那些代表真实的,实际上能实现的牙齿布局的构位,而“障碍”构位是那些不能实现的构位。 "Free" configurations are those that represent the true position, in fact, to achieve a configuration layout bit teeth, and "barrier" bit configuration is the configuration of bits that can not be achieved. 要决定一个构位是自由的还是障碍的,要为牙齿的位置创作一个构位描述的模型。 To determine a configuration bit is free or obstacles to the creation of the position of the teeth bit of a constitutive model described above. 然后,应用一种冲突检测算法来确定是否有一种几何形状描述牙齿表面的相交。 Then, apply a collision detection algorithm to determine whether there is a description of the geometry of the tooth surfaces intersect. 如果没有障碍,这个空间就被认为是自由的;否则就是障碍的。 If there are no obstacles, this space is considered to be free; otherwise, it is disorder. 这种冲突检测算法下面还要更详细地讨论。 This is discussed in more detail further below collision detection algorithm.

在步骤124中,确定了一种“可见度”函数V(s1,s2),这个函数在构位空间中取了两个矢量“s1”、“s2”作为输入并返回一个真或假的布尔值。 In step 124, it is determined, a "visibility" function V (s1, s2), this function takes two vectors "s1" bit in configuration space, "s2", as input and returns a true or false boolean value . 只有在一条连接s1、s2的直线路径整个穿过构位空间的自由和无障碍区域时,上述可见度函数才返回一个真实值。 Only when a connection s1, s2 of the linear path through the free and unobstructed areas entire configuration bit space, said visibility function returns a true value only. 可见度函数的一种优选的算法示于图8B。 A preferred visible function of the algorithm is shown in Fig 8B. 可见度函数可通过沿着s1、s2这条线在离散取样点上测试牙齿模型近似地计算出来。 Visibility function can along s1, s2 this line tested at discrete sampling points of the dental model approximately calculated. 这样的技术,例如早期失效终止或通过递归细分要测试的区间来选择取样点的次序,可用于提高可见度函数的效率。 The order of such techniques, such as early failure or terminated by recursive subdivision interval to be tested to select sampling points, can be used to improve the efficiency of the visibility function.

在图8A的步骤126中,确定了一种“产物”(children)函数C(s),它的输入参数“s”是构位空间中的一个矢量,并返回一组构位空间中的矢量“sc”。 In step 126 of FIG. 8A, a determination of a "product" (children) function C (s), its input parameter "s" is the configuration bits in a vector space, and returns a set of configuration bits in the vector space "sc". 图8C表示计算产物函数C(s)所要遵循的步骤的简化了的流程图。 8C shows a simplified procedure to calculate the product of a function C (s) to be followed by a flow chart. 在矢量组sc中的每一个矢量都满足V(s、sc)是真的特点,并且它的每一个分量都大于或等于相应的分量“s”。 In vector group sc each vector satisfies V (s, sc) is true characteristics, and each of its components are greater than or equal to the corresponding component of "s". 这意味着,任何由这样一个矢量所代表的状态都能从“s”达到,不会遇到任何干涉,并且不必完成任何不是在治疗方案规定的方向上的移动。 This means that any state represented by such a vector can be from the "s" is reached, do not experience any interference, and need not perform any movement in the direction of treatment prescribed. 每一个矢量组“sc”中的矢量都是通过用一些随机的,正向的量扰动“s”的各个分量而形成的。 Each vector group "sc" in the vector are used some random, positive amount of disturbance of "s" being formed by the respective components. 然后,计算出上述可见度函数V(s、sc),如果上述可见度函数返回到一个为真的布尔值,就把“s”加入到“sc”组中。 Then, calculate the above visibility function V (s, sc), if the above visibility function returns a Boolean value that is true, put the "s" added to the "sc" group. 此外,对于每一个如此产生的矢量都要把它的母矢量“s”的指针记录下来,以备后用。 In addition, for each such vector generated by the vector should put its parent "s" pointer recorded for later use.

在构位空间已经确定之后,在步骤128中,在原始状态“Sinit”与最后状态“Sfinal”之间完成路径的安排。 After the configuration bit of space has been determined, in step 128, in pristine condition to complete arrangements for the path between "Sfinal" "Sinit" and the final state. 图8D表示用于完成图8A中的步骤128的优选流程图。 Figure 8D Figure 8A shows a flowchart 128 of the steps for completing preferred. 如图8D所示,在步骤128a中,确定了一组最初只包含了原始状态“Sinit”的状态“W”。 8D, at step 128a, it is determined a set of original state originally contained only "Sinit" status "W". 接着,在步骤128b中,调用可见度函数来决定对于在W中对于至少一种状态si,V(S、Sfinal)是否是真。 Next, in step 128b, the visibility function is invoked to determine for the at least one state for the W si, V (S, Sfinal) whether it is true. 如果可见度函数返回到假布尔值,在步骤128c中,对于W中的所有Si,这一组状态“W”就用C(Si)的并集(union)来代替。 If the visibility function returns a false boolean value, at step 128c, for W all Si, the group status "W" on the use of C (Si) and set (union) instead. 重复步骤128b和128c,一直到V(S、Sfinal)对于任何属于W的Si均返回一个真布尔值。 Repeat steps 128b and 128c, up to V (S, Sfinal) for any part of W, Si both return a Boolean value true.

在步骤128d中,对于V(S、Sfinal)为真的各Si,通过从父指针返回到Sinit建立了一条从Si到Sinit的无障碍路径Pi。 In step 128d, for V (S, Sfinal) is true for each Si, by returning from the parent pointer to Sinit from Si to build a barrier-free path Sinit Pi. 在步骤128e中,从Sinit到Sfinal的路径是用从Si到Sfinal的最后的步骤把路径Pi串联在一起而建立起来的。 In step 128e, the path from Sinit to Sfinal is used from Si to Sfinal the final step of the path Pi strung together and set up. 如果从Sinit到Sfinal有多条路径,则在步骤128f中计算每一条路径的总长度。 If Sinit to Sfinal from multiple paths, then calculate the total length of each path in the step 128f. 最后,在步骤128g中,选择长度最短的路径作为最后的路径。 Finally, at step 128g, the shortest path length as the final path. 所选择的路径的长度与治疗计划所需要的总时间和阶段相对应。 Total time length of the treatment plan and the phase of the selected paths correspond required.

得出的最后路径由一系列矢量所组成,每一个矢量代表该移动牙齿的变换的平移和转动分量的一组内插参数值。 Final path obtained by a series of vectors, where each vector represents the translational and rotational components of the mobile tooth of a set of transformation parameters interpolated values. 把这些值放在一起,就组成了一个避免牙齿与牙齿干涉的牙齿移动的次序表。 These values are put together, they form a tooth to avoid interference with the tooth tooth movement order form.

冲突检测算法:本发明所用的冲突或干涉检测算法是根据SIGGRAPH论文中所公开的算法得来的,斯蒂芬.高恰尔克(StefanGottschalk)等人,(1996):“OBBTree:A Hierarchical Structure forRapid Interference Detection”。 Collision detection algorithm: conflict or interference detection algorithm used in the present invention is based on the algorithm SIGGRAPH papers disclosed come, Stephen high 恰尔克 (StefanGottschalk) et al., (1996): "OBBTree: A Hierarchical Structure forRapid Interference Detection ". 上述SIGGRAPH论文的内容作为本申请的参考文献。 The content of the paper as SIGGRAPH present application by reference.

这种算法的中心点是围绕着被一个物体所占据的空间的循环细分,其是以类似于二叉树的方式组织起来的。 The central point of this algorithm is subdivided by a loop around the space occupied by the object, which is similar to the way binary organized. 三角形用来代表DDS中的牙齿。 Used to represent the DDS triangular teeth. 树的每一个节点被认为是一个定向的边界框(OBB),包含了在节点的母体中出现的三角形的子集。 Each node of the tree is considered to be an oriented bounding box (OBB), comprising the nodes appearing in a subset of the triangular matrix. 母节点的子节点中包含了它们之间所有储存在母节点中的三角形数据。 Child node of the parent node contains all the triangle data stored in the parent node therebetween.

一个节点的边界框是这样来定向的,即,使得它紧紧地配合在上述节点中所有三角形的周围。 Bounding box of a node is to orient, i.e., such that it tightly fits around all the triangles in the above-mentioned nodes. 树中的叶节点在理论上包含单独一个三角形,但是也可以包含一个以上的三角形。 Tree leaf node containing a single triangle in theory, but may also contain more than one triangle. 检测两个物体之间的冲突就是要决定这两个物体的OBB树是否相交。 Collision detection between two objects is to decide which of two objects intersect OBB tree. 图9A示出描绘一种循环冲突测试的简化型式的流程图,以检查来自第一物体的“N1”是否与第二物体的节点“N2”相交。 9A shows a simplified version of a drawing of a flowchart conflict test cycle to check from the first object "N1" and the second object is a node "N2" intersect. 如果两颗树的根节点的OBB重叠,则对检查根的子节点是否重叠。 If two overlapping OBB tree root, the root of the child nodes to check whether the overlap. 上述算法以一种循环的方式进行,直到到达叶节点为止。 The above-described algorithm will be a circular manner, until the leaf node arrives. 此时,使用鲁棒性三角形交叉例程,来确定上述三角形在叶(端节点)处是否冲突。 In this case, the use of robust triangular cross routine, to determine the above-described triangle leaf (terminal node) whether the conflict.

本发明对SIGGRAPH论文中陈述的冲突检测的算法进行了一些改进。 The invention of the conflict detection algorithm SIGGRAPH paper statements made some improvements. 在一个实施例中,本发明提供了一种以缓慢的方式建立OBB树的独特方法,以节省存储器和时间。 In one embodiment, the present invention provides a way to establish a slow OBB tree unique method to save memory and time. 这种方法起源于观察到模型中有一部分是不会卷入冲突中的,因此不必计算模型的这些部分的OBB树。 This method originated in the observed part of the model is not involved in the conflict, it is not necessary to calculate the model these parts OBB tree. 如图9B所示,当在确定循环冲突算法的过程中必要时,OBB树是借助于拆分树的内部节点来扩展的。 9B, when the algorithm is necessary in determining the course of the cycle of conflict, OBB tree is split by means of internal nodes to the tree expansion.

在本发明的另一个实施例中,在建立OBB树时,也可以专门从设计中排除模型中不需要冲突数据的三角形。 In another embodiment of the present invention, when establishing OBB tree to be specifically excluded in the model does not require the conflict from the design data of the triangle. 如图9C所示,向冲突算法提供了附加的信息,以规定运动中的物体。 9C, collision algorithm to provide additional information to the provisions of objects in motion. 运动可以从两个层面上来看。 Movement from the two levels. 可以把物体看作全局的“运动”,或者,也可以看作相对于其他物体的“运动”。 The object can be seen as a global "movement" or, alternatively, can be seen in relation to other objects in the "movement." 由于避免了互相静止的物体之间冲突信息的重复计算,上述附加的信息缩短了用于冲突检测的时间,因为这些物体之间的冲突状态并没有改变。 By avoiding double counting conflict information between each other stationary objects, said additional information shortening the time for collision detection, because of the conflict between the state of these objects does not change.

本发明的软件也可以合并,而使用者可以在任何点上利用一种“电影”的特点,以自动激活从原始状态到目标状态的运动。 The software of the invention may also be combined, and the user can use a "movie" feature at any point, to automatically activate the original state to the target state motion. 这有助于使整个治疗过程中的全体部分的运动都能够看见。 This helps make the whole course of treatment in all parts of the movement can be seen.

以上说明了用于成分鉴别的优选用户界面是一种三维的交互的GUI。 Preferably the above described GUI user interface for component identification is a three-dimensional interaction. 三维的GUI对于部分的操作也是常用的。 For some of the three-dimensional GUI operation is also commonly used. 这样一种界面为专业治疗人员或使用者提供了带有数字模型成分的即时可见的交互作用。 Such an interface provides real-time visibility with a digital model of the interaction of components for professional treatment staff or users. 这对于那种只能让简单的,低层的命令来指示计算机操作一个特定区段的界面是更优选的。 This can make for the kind of simple, low-level commands to instruct the computer to operate a particular segment of the interface is more preferable. 换句话说,适合于操作的GUI对于只能接受这样的指令,例如:“使这个元件向右平移0.1mm的界面是更优选的”。 In other words, a GUI adapted to operate for only accept such an instruction, such as: "to make this element rightward panning 0.1mm interface is more preferred." 这种低层的命令对于微调是有用的,但,如果它们是唯一的界面,元件操作的处理过程将成为费力和耗时的交互作用。 Such low-level commands are useful for fine-tuning, but, if they are the only interface, the processing element operation will become laborious and time-consuming interaction.

在操作过程之前或当中,一个或者多个牙齿元件可以用牙根的样板模型来放大。 Prior to the operation or among one or more tooth root element can be used to amplify the template model. 操作用牙根模板放大的牙齿模型是有用的,例如,在需要关注在齿龈线以下的牙齿撞击的情况下。 Operation with an enlarged tooth root template models are useful, for example, in the following concern the case where the impact of the gum line of the teeth. 这些样板模型可以包括患者的牙齿的X射线的数字化的图像。 These template models may include digitized X-ray image of the patient's teeth.

这种软件还能把注解加在数据集中,其包括文本和/或装置的逐次号。 Such software can also add annotations in the data set, including a successive number of text and / or devices. 这种注解是作为凹入文本(即,它是三维的几何形状)加上去的,所以将出现在打印的正模型上。 This annotation is as recessed text (i.e., it is a three-dimensional geometry) added to the list, it will appear on the printed positive model. 如果这种注解能够放在将被一个重新定位的器械盖住的口部的一部分上,但其对于牙齿移动不重要,那么这种注解就可能出现在交付的重新定位的器械上。 If the annotation can be placed on a portion of the instrument by a repositioning of the mouth portion of the cover, but it is not important for tooth movement, then this annotation may appear on the delivered repositioning appliance.

以上所描述的元件标识和元件的操作软件设计成以与操作者的训练程度相匹配的复杂程度工作。 Operating software element identification and the element design described above as to the complexity of the training of the operator to match the job. 例如,操作元件的软件能通过提供有关牙齿的允许的和禁止操作的反馈来协助缺乏正牙训练的计算机操作者。 For example, the software can provide information about the operating element of the teeth and allow feedback to help prohibit the operation of a lack of orthodontic training computer operator. 另一方面,一个在口腔生理学和牙齿移位动力学方面技术非常熟练的正牙医生,就能够方便地用这种元件标识和操作软件作为工具,而不使用或者忽略提示。 On the other hand, a shift in the dynamics of the teeth and oral physiology technical very skilled orthodontist, you can easily use this device as a tool to identify and operating software, without the use of or ignore the prompt.
