Abstract:
A process for the production of one of a fully-ceramic inlay, crowns, bridge, partial bridge or frames for an implant or superstructure in dentistry, comprisingproducing a frame from a ceramic by shrink-fitting on a die of a working model a film; or covering the die of the working model with a separating agent which is liquid at temperatures above 45Â° C. and which, at room temperature, has a lipstick consistency; applying a slip to the shrink-fitted film or separating agent; removing the slip present on the film or separating agent from the working model; after the separation from the working model, baking the slip material; and, after baking to produce the frame in the form of a resulting mold blank, infiltrating the blank with glass, wherein during the slip application, the die is fixed on a rotating rod, of a computer numerical control milling machine, and further comprising sensing the surface profile of the die storing this profile, controlling a dosing device via the stored data, applying the slip uniformly on the film or separating agent and subsequently milling off the applied slip material by means of the stored data to a desired thickness.
