In this paper, we present an approach for the reconstruction of teeth model. Therefore, a tooth model has to be scanned from several directions with a 3D-laser scanner. Several views are necessary because of shadows and occluded areas in the range images. Then, all acquired range views are combined to build a CAD-model of the tooth. The idea is that every part of the surface should be visible in at least one view. The reconstruction process is divided into the steps registration, volume sculpturing and generation of an accurate polygonal representation.
