System and method for detecting deviations during the course of an orthodontic treatment to gradually reposition teeth
WO 2008149222 A3
Abstract
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 (S700A) and before the plan ends for the patient; matching (S705) a previously segmented teeth model with the current teeth image; and generating at least one corrective stage (S707) 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.
