摘要： 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.

摘要： A method for manufacturing a dental prosthesis, such as a dental crown, wherein at least the visible part of the prosthesis (the outside) is subjected to a material removing operation by means of a numerically controlled micro machine tool and wherein the machining paths are visible on the final prosthesis. Said machining paths follow a three-dimensionally curved line and do no lie in a flat plane, therefore. The dental prosthesis which is manufactured in this manner has a natural-looking appearance. According to another aspect of the invention the shape of the dental prosthesis is such that near the edge of the prosthesis the cement layer is thicker than at some distance from said edge. Therefore the edge of the dental prosthesis is released from heavy forces.
