    Abstract: 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.

    Abstract: 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.

    Abstract translation: 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，可以在病人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。

    Abstract: 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 nullroot-firstnull 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.

    Abstract: An improved dental appliance system, and methods for using and fabricating the improved appliance, including a polymeric overlay or shell having a teeth-receiving cavity formed therein. The dental appliance having the necessary stiffness or strength to firmly secure the appliance on the teeth and provide controlled forces required for repositioning the teeth, until such time as removal of the appliance is desired. The appliance may be configured for use with a removal mechanism. The removal mechanism provides for selective release of the appliance from the teeth as the removal mechanism undergoes a state change stimulated by an environmental stimulus or environmental switch.

    Abstract: A programmed computer is used to create a digital model of an individual component of a patient's dentition. The computer obtains a 3D digital mode of the patient's dentition, identifies points in the dentition model that lie on an inter-proximal margin between adjacent teeth in the patient's dentition, and uses the identified points to create a cutting surface that separates portions of the dentition model representing the adjacent teeth.

    Abstract: Practitioners are certified to perform a medical procedure, such as an orthodontic procedure. Certified practitioners are maintained in a referral directory and classified within tiers based on criteria such as the number of procedures that they have performed. Inquiries are solicited from prospective patients, and referral lists are provided to those patients who request them. The referral lists are obtained from the referral directory with doctors from higher tiers who have performed more procedures receiving preferential inclusion on the referral lists.
