Abstract

Methods for obtaining an adjusted 3D model of patient's teeth based on a 2D image of the patient's teeth. In some examples, the method includes: obtaining a 3D digital model based on a scan of the patient's teeth; obtaining a 2D image based on a camera picture; iteratively comparing a distance between corresponding points on one or more teeth of the 3D digital model and of the 2D image, and generating an adjusted 3D model in which the one or more teeth of the 3D digital model are moved to reduce said distance, wherein iteratively comparing and generating comprises iterating until one or more deviations between the teeth of the 3D digital model and the 2D image are below a threshold.
