    Abstract: A processing device receives a 3D model including a 3D crown component from a scan and a 3D root component from a template. The processing device receives a 2D x-ray image of the at least one tooth and generates a scan model representing an initial estimate of the one or more parameters of an x-ray imaging device that created the 2D x-ray image. The processing device further generates a 2D contour of the at least one tooth based on projecting the 3D model onto a plane using the scan model. The processing device overlays the 2D contour onto the 2D x-ray image. The processing device further adjusts the 2D contour to cause a first crown component of the 2D contour to approximately align to a second crown component of the 2D x-ray image. The processing then calibrates the scan model based on data obtained from adjusting the two-dimensional contour.

    Abstract translation: 处理设备从扫描中接收包括3D冠状分量的3D模型和来自模板的3D根分量。 所述处理装置接收所述至少一个牙齿的2D X射线图像，并且生成表示创建2D X射线图像的x射线成像装置的一个或多个参数的初始估计的扫描模型。 基于使用扫描模型将3D模型投影到平面上，处理装置进一步产生至少一个牙齿的2D轮廓。 处理设备将2D轮廓覆盖到2D x射线图像上。 处理装置进一步调整2D轮廓以使得2D轮廓的第一冠部分量与2D x射线图像的第二冠状部分大致对准。 然后，处理基于从调整二维轮廓获得的数据来校准扫描模型。

    Abstract: Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems of the invention include tooth attachments having improved or optimized parameters selected or modified for more optimal and/or effective application of forces for a desired/selected orthodontic movement. Attachments of the present invention can be customized to a particular patient (e.g., patient-customized), a particular movement, and/or a sub-group or sub-set of patients, and configured to engage an orthodontic tooth positioning appliance worn by a patient, where engagement between the attachment and orthodontic appliance results in application of a repositioning force or series/system of forces to the tooth having the attachment and will generally elicit a tooth movement.
