Patent ID: 6974323

Claim:
A method for automated production of dental prostheses in the form of ceramic dental restorations or ceramic, individually formed abutments of dental implants, using a computer-controlled laser for shaping by means of removal of material from a ceramic blank, characterized in that at least one three-dimensionally contoured surface region of the dental prosthesis is machined out of the ceramic blank by means of an ultra-short-pulse laser and shaped into the predetermined shape, wherein by means of the ultra-short-pulse laser, in a first work step, a great majority of the material to be removed from the ceramic blank in order to machine out the three-dimensionally contoured surface region of the dental prosthesis is cut off in pieces, and the surface of the ceramic blank is approximated to the surface to be produced as the dental prosthesis, and then the remainder of the material present above the surface to be shaped of the dental prosthesis is vaporized by erosive operation of the ultra-short-pulse laser.
