Embodiment Construction

[0070] Elements corresponding to or identical to each other in the following embodiments are denoted by the same reference numerals.

[0071] figure 1 A CAD / CAM machining system 1 is shown comprising a CAD / CAM machining station 2 for producing ceramic prosthetic components. The CAD / CAM machining system 1 comprises at least one CAD device 3.1 for generating a CAD file 4.1 specifying the final dimensions of one or more of the prosthetic components to be produced.

[0072] For example, the CAD device 3.1 comprises a scanner for acquiring 3D measurement data from the patient; instead, the 3D measurement data may be received in digital form from a dentist. The CAD device 3.1 is used to execute CAD software in order to generate CAD files 4.1 for specifying the prosthetic components to be produced. Suitable scanners are commercially available, such as the inEosX5 from DentsplySirona.

[0073] The CAD file 4.1 can be transmitted to the machining station 2 via a communication networ...

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.

Description

[0001] Cross References to Related Applications [0002] This patent application claims the benefit and priority of European Patent Application No. 18206460.0 filed on November 15, 2018, which is hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a method for producing ceramic denture parts by means of a CAD / CAM machining station, a corresponding CAD / CAM machining station and a computer program for controlling the CAD / CAM machining station, and a method consisting of Disc-shaped blanks made of ultimate-strength dental ceramics. Background technique [0004] A method for producing dental restorations is known from WO 2004 / 086999 A1, in which a disk-shaped blank is processed, which is present in green or not yet final sintered form. According to this previously known method, final strength blanks cannot be processed. [0005] Rather, the object of the present invention is to produce an improved method of producing cer...
