摘要： A computer is used to create a plan for repositioning an orthodontic patient's teeth. The computer receives an initial digital data set representing the patient's teeth at their initial positions and a final digital data set representing the teeth at their final positions. The computer then uses the data sets to generate treatment paths along which teeth will move from the initial positions to the final positions.

摘要： A computer obtains a digital model of a patient's dentition, including a dental model representing the patient's teeth at a set of initial positions and a gingival model representing gum tissue surrounding the teeth. The computer then derives from the digital model an expected deformation of the gum tissue as the teeth move from the initial positions to another set of positions.

摘要： The present invention provides improved devices, systems and methods for repositioning teeth from an initial tooth arrangement to a final tooth arrangement. Repositioning is accomplished with a system comprising a series of polymeric shell appliances configured to receive the teeth and incrementally reposition individual teeth in a series of successive steps. The individual appliances may be formed from layers having different stiffnesses (elastic moduluses), and the stiffnesses of successive appliances may be different, or both.

摘要： The present invention provides methods and systems of repositioning teeth for use in orthodontic treatment, with particular applicability to removable elastic repositioning appliances. Such appliances may be challenged by traditional tooth movements which intrude the crown of the tooth or present tooth positions which reduce available points of purchase. These challenges may be overcome with a series of tooth movements in which a tooth is translated in a “root-first” position. The movements may take advantage of the inherent characteristics of elastic repositioning appliances in translating a tooth from a first position to a desired position along a gingival plane.

摘要： A system for repositioning teeth comprises a plurality of individual appliances. The appliances are configured to be placed successively on the patient's teeth and to incrementally reposition the teeth from an initial tooth arrangement, through a plurality of intermediate tooth arrangements, and to a final tooth arrangement. The system of appliances is usually configured at the outset of treatment so that the patient may progress through treatment without the need to have the treating professional perform each successive step in the procedure.

摘要： The present invention provides a manipulable or reconfigurable dental model system and methods for its use to model a series of tooth configurations corresponding to sequential tooth movements during an orthodontic treatment. When a patient undergoes orthodontic treatment, teeth and bite configurations are realigned in a series of stages. Each stage represents a new pattern or dental configuration that will eventually lead to a proper final positioning of the entire dentition. Progress from the initial configuration, through the intermediate stages and finally to the final configuration may be accomplished using any one or a combination of different dental appliances. Of particular interest to the present invention, many of these appliances may be made using a dental mold representing the patient's dental configuration. In particular, thermoformable plastic positioning appliances which fit over the patient's teeth may be formed over a three-dimensional mold of the patient's dentition. When successive appliances are used throughout treatment to reposition the teeth from initial to final configuration, a new mold has typically been produced to fabricate the appliance for each stage. The present invention provides an apparatus and methods which employ a manipulable or reconfigurable mold to model patient dentition and gingiva at each stage of treatment.

摘要翻译： 本发明提供了可操纵或可重新配置的牙齿模型系统及其用于在正牙治疗期间对应于顺序牙齿移动的一系列牙齿构造的建模方法。 当患者进行正畸治疗时，牙齿和咬合配置在一系列阶段重新对齐。 每个阶段代表一种新的模式或牙齿配置，最终将导致整个牙列的适当的最终定位。 可以使用任何一种或不同牙科器具的组合从初始构型，中间阶段和最后到最终构型的进展。 对于本发明特别感兴趣的是，许多这些器具可以使用表示患者牙科构造的牙科模具来制造。 特别地，可以在患者牙齿的三维模具上形成适合患者牙齿的热成型塑料定位器具。 当在整个治疗期间使用连续的器具以将牙齿从初始配置重新定位到最终配置时，通常已经生产出新的模具来制造每个阶段的器具。 本发明提供一种在每个治疗阶段使用可操纵或可重构模具来模拟患者牙列和牙龈的装置和方法。
