Vorrichtung und Verfahren zum Herstellen einer zahnärtzlichen Füllmasse für die Wiederherstellung von Zahnkronen

摘要

Process and apparatus for producing a dental filling for restoration of a tooth crown (49, 55), the dental filling being fitted to a cavity prepared in the tooth for filling the cavity. The apparatus includes a cutting device (10) for preparing the cavity, the cutting device including a cutting element (11, 26, 34) for cutting the tooth for the cavity preparation, and a cutting-element position sensor (12) for monitoring movement of the cutting element for the cavity preparation and thereby producing a batch of outline form data representing a three-dimensional outline form of the cavity; a memory device (42) for storing the batch of outline form data; a machining device (46) for machining a prefabricated filling blank into the dental filling; and a control device for controlling operation of the machining device according to the batch of outline form data, so that the filling blank is machined into the dental filling having an outline form identical with the outline form of the cavity.
