    Abstract: Methods and systems for dental treatment are provided. In some embodiments, a method includes receiving a plurality of treatment stages for repositioning a patient's teeth from an initial tooth arrangement toward a target tooth arrangement, where each treatment stage is associated with a target position for a tooth of the patient. The method can include determining, for one or more treatment stages, an overcorrected movement corresponding to an overcorrected position for the tooth that is different from the target position, where at least some of the one or more treatment stages include different magnitudes of overcorrected movements. The method can further include outputting fabrication instructions for one or more dental appliances corresponding to the one or more treatment stages, each dental appliance including an overcorrected tooth receiving cavity corresponding to the overcorrected position for the respective treatment stage.

    Abstract: Embodiments of the present disclosure include computing device related, system, and method embodiments for virtually testing force placed on a tooth are described herein. One method embodiment includes receiving initial orthodontic data (IOD) of teeth, and receiving a desired position of a tooth contained in the IOD. The method embodiment can also include computing a desired force and torque to be applied to the tooth to reach the desired position, wherein the force and torque are applied using a dental attachment. The method embodiment can include virtually testing and adjusting the attachment iteratively to reach the desired force and torque, and displaying the force and torque applied to the tooth via a user interface.

    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 include the generation of an overcorrection in the tooth-receiving cavities of an appliance worn in the dentition. The overcorrection may provide an improved and more accurately applied force or moment applied to a tooth. The overcorrected force or moment can move a tooth closer to a desired position than if not overcorrected as sufficient force can still applied to the tooth as it gets closer to the desired position. The overcorrected force or moment may also better target the root of the tooth where the biological response to tooth movement occurs. The overcorrection may be calculated in various ways as described herein.

    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.
