A method for manufacturing a dental prosthesis, wherein the shape of the prepared part of the teeth in question is established by scanning at least a part of the teeth, or a replica thereof, by means of a three-dimensional scanner. In order to be able to determine the desired shape of the prosthesis, it is necessary to know not only the shape of the part of the teeth in question, but also the circumferential edge of the preparation, i.e. that part of the teeth which has been prepared for receiving the dental prosthesis. The preparation line is made visible to the scanner by providing the teeth at one side of this preparation line with a coating which the scanner is capable of recognizing. <IMAGE> |
