Abstract
The invention aligns a digital face model from a 3D face scanner with a 3D teeth model from an intraoral scan produced by an intraoral scanner without using external markers. The alignment proceeds in two steps. In the first step, the teeth part of a subject whose teeth are clenched, referred to as a clenched-teeth face scan, is aligned with the teeth model from an intraoral jaw scan to obtain a first transformation matrix. In the second step, a face model of a subject with a normal facial expression is aligned with the clenched-teeth face model of the same subject using an ICP algorithm.
