Abstract: The invention relates to a disk-shaped blank made of a final-strength dental ceramic, comprising a casing surrounding a perimeter of the final-strength dental ceramic, the casing made of a material that is softer than the final-strength ceramic, and in particular made of wood or plastic material.

Abstract: The invention relates to a method for producing ceramic dental prosthesis parts by way of a CAD/CAM machining station, comprising the following steps:—providing a disk-shaped ceramic blank, wherein the blank has the final strength;—attaching the blank in a mounting device of the CAD/CAM machining station;—controlling the CAD/CAM machining station for establishing an initial contact between the blank and the grinding tool in such a way that, due to the rotation of the grinding tool about the longitudinal axis (13) thereof, the entire contact surface (21) between the grinding tool and the blank has relative movement; and—machining the blank by way of the rotating grinding tool, proceeding from the initial contact, to produce the ceramic dental prosthesis parts.
