In this paper, we compare two vision registration methods of 3D models to develop a main tool for orthodontics based on the virtual occlusion of two dental casts. For that purpose, we process photos of the patient mouth and match points between pictures and dental geometrical models. From a set of 2D/3D matches of the two arcades, we calculate the projection matrix, and after we do the registration of the mandible under the maxillary through a rigid transformation. Two methods with or without the knowledge of camera intrinsic parameters are compared. Minimizing the reprojection errors, we perform the registration of the mandible. Tests are carried out on virtual data and real images. Using a virtual case, assumed as perfect, we evaluate the robustness against noise and the increase of performance using several views. Projection matrices and registration are evaluated, respectively, by reprojection errors and the recorded differences on the 6 parameters of rigid transformation compared with the reference pose.
