FACE TRACKING AND REPRODUCTION WITH POST-TREATMENT SMILE

Abstract:

A processing device receives a pre-treatment model of upper and lower dental arches of a person, the pre-treatment model comprising first positions of teeth, and further receives a post-treatment model of the upper and lower dental arches, the post-treatment model comprising second positions of the teeth. The processing device determines a first mapping between first positions of first landmarks in the pre-treatment model and second positions of the first landmarks in the post-treatment model, and receives an image of a face of the person, comprising at least the teeth and soft facial tissues. The processing device generates a second mapping between the first landmarks and second landmarks associated with the soft facial tissues from the image, and generates a facial model comprising the first mapping and the second mapping, wherein the facial model generates post-treatment images of the teeth and the soft facial tissues based on pre-treatment images.
