Modeling of the occlusal surface of teeth is an important problem in computer-aided design of dental restorations. The designed shape must fit the existing individual anatomy of the patient. Also, the design process must be fast to be practical in clinical applications. To fulfil these requirements a new technique for automatic adaptation of the occlusal surface for the restoration of teeth has been developed. By introducing free function assignment in the control points and an dimensional independency the basic concept of geometrically deformable models has been generalized. The presented approach handles also the problem of model generation und interactive model modifications. Further tests on synthetically produces images and real medical records proved its accuracy and many-sidedness.
