Method and device for the manufacture of medical in particular dental, prosthesis

Abstract

Abstract In order to simplify the manufacture of prostheses, it is proposed to first of all produce a positive or negative pattern (42) of the prosthesis or the object into which the prosthesis is to be inserted, then to insert the pattern into a holding fixture (7) of a cutting machine (3) and to measure it three-dimensionally by means of a measuring device (9). The measured data are then fed to a control unit (48). After the pattern is measured, a workpiece blank (10) is inserted instead of the pattern (42) into the holding fixture (7), from which workpiece blank (10) the prosthesis is then made by means of at least one cutting tool (26, 37), in the course of which drive motors and servomotors (14, 17; 25, 28, 31; 38, 40, 41) for the holding fixture (7) and the cutting tool (37) for machining the workpiece blank are activated with the control signals obtained from the measured data. <IMAGE>
