    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： 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： 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 appliances configured to receive the teeth in a cavity and incrementally reposition individual teeth in a series of successive steps. This is accomplished by applying force to specific surfaces of the teeth through stiffness of the appliance. However, such stiffness creates limitations in ease of use, patient compliance, and overall cost in material, manufacturing labor and treatment time. To overcome these limitations, the present invention utilizes polymeric or other material appliances with portions differing in rigidity or stiffness. Alternatively, elastic moduluses may differ from one appliance to the next in a successive series to accomplish various treatment goals. Thus, the systems and methods of the present invention provide the design, production and use of such multiple stiffness positioning appliances in orthodontic treatment. Similarly, the devices of the present invention provide differing stiffness appliances which may be used independently for purposes other than repositioning, such as for retaining teeth in a desired position.

    摘要翻译： 本发明提供了用于将牙齿从初始牙齿布置重新定位到最终牙齿布置的改进的装置，系统和方法。 重新定位是通过一系统来完成的，所述系统包括一系列聚合物器具，其被配置为在空腔中接纳牙齿，并且在一系列连续步骤中递增地重新定位各个牙齿。 这是通过对器具的刚度施加力到齿的特定表面来实现的。 然而，这种刚度在易用性，患者依从性以及材料，制造劳动和治疗时间的整体成本方面造成了限制。 为了克服这些限制，本发明使用具有刚性或刚度不同部分的聚合物或其它材料器具。 或者，弹性模块可以在连续的系列中从一个装置到下一个装置不同，以实现各种处理目标。 因此，本发明的系统和方法提供了这种多重刚度定位装置在正畸治疗中的设计，生产和使用。 类似地，本发明的装置提供不同的刚度装置，其可以独立地用于除重新定位之外的目的，例如用于将齿保持在期望位置。

    摘要： 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.

    摘要： Traditional orthodontic treatment often involves the use of basic repositioning devices, such as braces, and the use of supplementary devices, components or accessories to achieve desired end results. Such components may be mounted on fixed, non-removable devices or they may be part of a removable appliance typically worn prior to the application of the fixed devices. As with traditional treatment, it may be desired to utilize similar components when repositioning teeth with removable elastic repositioning appliances. Due to the nature of elastic appliances, such components may take a variety of forms ranging from readily available traditional accessories to specially created devices. Thus, traditional components may be mounted on or embedded in an elastic appliance, or the appliance may be formed to provide similar components. Likewise, the appliance may be modified to provide additional features for specific orthodontic treatments.
