Abstract
Disclosed is a computer-implemented method for closing one or more holes in a bottom section of a three-dimensional digital preparation model of a preparation of a tooth. The tooth is prepared for receiving a dental restoration element with a lower limit of the bottom section of the preparation being prepared in form of a stepless edge. The method comprises receiving the three-dimensional digital preparation model of the prepared tooth. One or more holes of the three-dimensional digital preparation model to be closed are detected within the bottom section. A preparation angle used for preparing the bottom section is determined and the detected one or more holes are closed. The closing comprises an extrapolation of the bottom section into the holes using the determined preparation angle.
