    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 and a wire mounted on or embedded in the polymeric shell. 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 mechanisim. The removal mechanism undergoes a state change stimulated by an environmental stimulus or environmental switch.

    Abstract: 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.

    Abstract: The present invention provides improved systems and methods for removably attaching a dental positioning appliance to the dental features of a patient during orthodontic treatment. Such removable dental positioning appliances are often preferred over conventional braces for tooth repositioning due to comfort, appearance and ease of use. These appliances function by applying force to specific surfaces of the teeth or dental features to cause directed movement. However, the type of movement and level of force applied is usually dependent on the surface characteristics and positions of the dental features. In many cases, these aspects are inadequate to provide sufficient anchoring or to impart considerable force on the teeth to be repositioned. Such limitations may be diminished with the use of one or more attachment devices which may be positioned on the teeth or dental features to provide the appropriate physical features. Specific design and location of these attachment devices may provide newly achievable and/or more effective repositioning forces, anchoring ability and appliance retention. The systems and methods of the present invention provide the design, production and use of such attachment devices with removable dental positioning appliances in orthodontic treatment.

    Abstract translation: 本发明提供了用于在正畸治疗期间将牙科定位器具可移除地附接到患者的牙齿特征的改进的系统和方法。 由于舒适性，外观和易用性，这种可移动牙科定位装置通常优于常规的用于牙齿重新定位的支架。 这些器具通过对牙齿的特定表面或牙齿特征施加力来引起定向运动。 然而，运动的类型和施加的力水平通常取决于牙齿特征的表面特征和位置。 在许多情况下，这些方面不足以提供足够的锚定或赋予待重新定位的牙齿上相当大的力。 通过使用可以定位在牙齿或牙齿特征上的一个或多个附接装置来提供适当的物理特征，这种限制可能会减弱。 这些附接装置的具体设计和位置可以提供新的可实现和/或更有效的重新定位力，锚固能力和器具保持力。 本发明的系统和方法提供了在正畸治疗中这种具有可移除的牙科定位器具的附接装置的设计，生产和使用。

    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 “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.

    Abstract: A positive mold for use in creating an orthodontic appliance is produced by obtaining a digital dentition model, such as a 3D geometric surface model or a 3D volumetric image model, that defines the shape of an orthodontic appliance and then altering the digital dentition model to remove a portion that does not affect the shape of the orthodontic appliance. The altered digital dentition model then is used to construct a positive mold for the orthodontic appliance. Processing circuitry, such as a programmed computer, is used to obtain and alter the digital dentition model. A rapid prototyping device, such as a stereolithography machine, is commonly used to construct the positive mold.
