Abstract
In the process for producing dental phostheses such as bridges, crowns implants, etc. from ceramic material, production is carried out at least by way of one CAD/CAM machining station. The ceramic material to be worked consists of an unsintered disk-shaped blank or one which has not been subjected to final sintering, working of the blank into dental prostheses being undertaken at a right angle or quasi-right angle to the parallel or quasi-parallel surfaces of the blank.
