Patent ID: 7822581

Claim:
A method for processing data regarding a dental prosthesis, the method comprising the steps of: a) providing input data which represent a three-dimensional surface of a tooth stump prepared for a prosthesis; b) providing stability requirements for the prosthesis, wherein the stability requirements include a minimum required thickness of the prosthesis, c) generating control data from said input data, said control data representing a control surface which meets the stability requirements, d) generating design data from said input data and separately from the control data which represent the three-dimensional shape of the prosthesis, and e) displaying the shape of the prosthesis together with the control surface on a monitor; wherein the displayed control surface provides a visual representation of the minimum required thickness, the design data are modified by a user based on a visual comparison of the displayed design data and the displayed control surface in order to meet the stability requirements; and the design of the prosthesis corresponding to the modified design data is displayed on the monitor together with the control surface.
