Abstract

A process for determining 3-D data of at least one prepared jaw area, such as a prepared tooth stump, by mechanically scanning the jaw area and digitizing the measured values determined during the scanning. The jaw area is prepared with a dental instrument having positions which are optically measured during the preparation, and the 3-D data is determined from the positions of the dental instrument that are associated with the prepared jaw area.
