[Computer-assisted technologies in dentistry]

The introduction and production of the Cerec-System was the first time, when a method of computer-aided design and manufacturing (CAD/CAM) of dental restorations moves to the chairside. New technologies like optical impression, solid modelling of crown shapes by CAD-Programs or computer controlled milling were acquired from the field of industrial production. Nevertheless, the Cerec-Systems is indicated only in a limited range of clinical situations, and the production of a well fitting computer-designed full crown is not yet possible at this stage of development. It can only be guessed whether these advancements will be achieved in the near future.
