Abstract
The method described in this disclosure permits the production of dental replacements, such as inlays, onlays, and crowns, at high accuracy of fit and low cost in a single session of the patient's at the dentist's. For this purpose, a material that hardens is used for making a temporary inlay which provides an impression of the prepared dental cavity. After hardening, this material is removed from the tooth. In a first processing run, a first sensor (7a) does a preliminary scan of the temporary inlay (4) and a first processing tool (30a) is used for preliminary processing of the substrate mass (6). In a second processing run a second sensor (7b) and a second processing tool (30b) are used for a fine scan and fine processing. For this purpose the sensors (7a, 7b) and the processing tools (30a, 30b) are all arranged on a single linear stage (13). The temporary inlay (4) and the substrate mass (6) are attached to holder units (3, 5 ) of a rotation-synchronizer system (10) which in turn is arranged on a slide and elevator system (11, 12).
