Method for automated production of ceramic dental restorations and prostheses |
摘要 |
The method is used for automated production of dental prostheses in the form of ceramic restorations or ceramic abutments of dental implants, using a computer-controlled laser for shaping by means of removal of material from a ceramic blank. The special feature is that at least one three-dimensionally contoured surface region of the dental prosthesis ( 4, 8 ) is machined out of the ceramic blank ( 3 ) by means of an ultra-short-pulse laser ( 1 ) and shaped into the predetermined shape. Preferably, the ultra-short-pulse laser is first employed in such a way that the great majority of the material to be removed from the ceramic blank is cut off in pieces by the ultra-short-pulse laser, and then the ultra-short-pulse laser need merely vaporize the remainder in an erosive operation.
