    • A prescription for an orthodontic brace is selected by providing data representing a number of teeth of the dental arch and by displaying images of the teeth in two or more different positions. Images of at least one tooth when in the first position and when in the second position are simultaneously displayed in superimposed fashion, and any difference in orientations of the displayed tooth images between the first position and the second position appears in contrast. As a consequence, the relative difference in positions can be readily observed. The invention is particularly useful for selecting a prescription of a brace from two or more prescriptions, and is also useful for observing the relative effect of a single prescription when used on certain teeth in comparison to the position of the same teeth during an earlier stage of treatment.
    • 通过提供表示牙弓数量的数据并且通过在两个或更多个不同位置显示牙齿的图像来选择正畸支架的处方。 在第一位置和第二位置的同时以叠加方式显示至少一个齿的图像,并且与第一位置和第二位置之间显示的齿图像的取向方向上的任何差别都出现了对比。 因此,可以容易地观察到位置的相对差异。 本发明对于从两个或多个处方中选择支具的处方特别有用,并且在用于某些牙齿时观察单个处方的相对效果与在同一个牙齿的较早阶段期间与相同牙齿的位置相比是有用的 治疗。

    • A computer implemented method of creating a dental model for use in dental articulation includes providing a first set of digital data corresponding to an upper arch image of at least a portion of an upper dental arch of a patient, providing a second set of digital data corresponding to a lower arch image of at least a portion of a lower dental arch of the patient, and providing hinge axis data representative of the spatial orientation of at least one of the upper and lower dental arches relative to a condylar axis of the patient. A reference hinge axis is created relative to the upper and lower arch images based on the hinge axis data. Further, the method may include bite alignment data for use in aligning the lower and upper arch images. Yet further, the method may include providing data associated with condyle geometry of the patient, so as to provide limitations on the movement of at least the lower arch image when the arch images are displayed. Further, a wobbling technique may be used to determine an occlusal position of the lower and upper dental arches. Various computer implemented methods of dental articulation are also described. For example, such dental articulation methods may include moving at least one of the upper and lower arch images to simulate relative movement of one of the upper and lower dental arches of the patient, may include displaying another image with the upper and lower dental arches of the dental articulation model, and/or may include playing back recorded motion of a patient's mandible using the dental articulation model.
    • 创建用于牙科关节的牙科模型的计算机实现方法包括提供对应于患者的上牙弓的至少一部分的上拱形图像的第一组数字数据,提供对应于第二组数字数据的第二组数字数据 到达患者的下牙弓的至少一部分的较低拱形图像,并且提供表示上部和下部牙弓中的至少一个相对于患者的髁轴线的空间取向的铰链轴数据。 基于铰链轴数据,相对于上下拱形图像创建参考铰链轴。 此外,该方法可以包括用于对准下部和上部拱形图像的咬合对准数据。 此外,该方法可以包括提供与患者的髁几何相关联的数据,以便当显示拱形图像时对至少下弓形图像的移动提供限制。 此外,可以使用摆动技术来确定下牙弓和上牙弓的咬合位置。 还描述了各种计算机实现的牙科关节的方法。 例如,这种牙科关节法可以包括移动上部和下部弓形图像中的至少一个以模拟患者的上部和下部牙弓之一的相对运动,可以包括将另一个图像与上部和下部牙弓 牙科关节模型和/或可以包括使用牙科关节模型回放患者下颌骨的记录运动。
