摘要:
The invention relates to a method for producing tooth parts from dental-grade metal powder, wherein existing CAD/CAM milling machines can be used. The essential process steps consist of: a) preparing a slurry from dental-grade metal powder, b) casting the slurry into a mold, c) drawing out (drying) suspension liquid (water) until a mechanically stable blank is obtained, d) milling the blank into the desired shape, e) oxygen-free sintering of the tooth parts milled from the blank. Because the blank is still present as a green body, milling does not place great demands on the milling machine in terms of mechanical stability and dust development. As a result, the operating speed and the service lives of customary milling machines are substantially increased.
