Case 91-H05 Europe Abstract of the disclosure 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).
