Abstract

Restoration of the occlusal teeth surface is an important aspect in dental CAD system. The designed surface shape must fit the existing jaw articulation and keep the anatomy features of the generic teeth. In this paper we presented a new method for teeth surface restoration based on space mapping deformation technology. The main focus on this method is the dental surface global and local mapping deformation using radial basis function (RBF) according to the corresponding feature points of the standard tooth and the preparation. The space mapping deformation method has been successfully applied on some preparation, which can guarantee the surface matching smoothness and keep the main anatomical features of teeth.
