    摘要： System and methods for positioning 3D virtual brackets on teeth for the precise positioning of conventional brackets and wire. Various reference features may be calculated for the teeth and used to calculate a position for the virtual bracket. Reference features that are calculated include curve of Spee, Andrew's plane, and a facial axis of the clinical crown for the teeth.

    摘要： A computer obtains a digital model of a patient's dentition, including a dental model representing the patient's teeth at a set of initial positions and a gingival model representing gum tissue surrounding the teeth. The computer then derives from the digital model an expected deformation of the gum tissue as the teeth move from the initial positions to another set of positions.

    摘要： Method and system for detecting and correcting deviation during an orthodontic treatment plan is provided. The method includes the steps of receiving an un-segmented current teeth image representing a patient's teeth after an orthodontic treatment plan has begun and before the plan ends for the patient; matching a previously segmented teeth model with the current teeth image; and generating at least one corrective stage to define an intermediate tooth arrangement, wherein the at least one corrective stage repositions a digital teeth image so that a prescribed tooth arrangement of the previously segmented teeth model can be used.
