Abstract: The invention describes a device for positionally fixing a moulding comprising a base surface having at least one fixing element for the moulding, characterized in that at least one positioning means is provided which interacts with the fixing element, and the moulding has at least one position marking which interacts with the positioning means.

Abstract: Embodiments relate to a dental prosthesis molding block for producing a dental prosthesis part, to a corresponding method for producing a dental prosthesis part, and to such a dental prosthesis part. The dental prosthesis molding block has a dentin zone, which is embedded into an enamel region, a boundary surface thus being formed. The boundary surface of the dentin zone has a first dentin surface, which is directed toward the labial surface of a first potential dental prosthesis part, and a second boundary surface for forming a second dentin surface, which is directed toward the labial surface of a second potential dental prosthesis part. The first and second dentin surfaces preferably have respective convex shapes, wherein the sizes and/or shapes of the two dentin surfaces preferably differ from each other.
