ABSTRACT:
Around a tooth, a molding cavity is formed which is closed at the tooth face and tooth flanks and in which the mold material forms a dome due to its surface tension. Said dome is flattened prior to the solidification of the material for approximation to the intended profile of the tooth back by exerting a pressure on the dome which pressure is moved progressively in the direction towards the tooth tip. When the hard material is melted with a gas or plasma jet the latter can be moved after the melting of the hard material in the direction towards the tooth tip over the dome. The gas jet is used to smooth the material after a first heating torch is used to melt the material.
