Described is a method for manufacturing a dental prosthesis, in particular a crown, from a blank which is clamped and machined in a chuck of a machine tool. Also described is a device for implementing this method. To minimize scrap from the blank, the blank is imbedded in a ring and the ring is clamped with the blank in the chuck. The device provides that the blank, the external dimensions of which are no larger than necessary for machining the dental prosthesis, is imbedded in a ring made of metal, ceramic or hard plastic. |
