The present invention relates to a dental prosthesis molding block for producing a dental prosthesis part. The block comprises an inner material that is at least partially surrounded by an outer material, the hardness of which differs from the hardness of the inner material. The inner material forms part of a first surface of the dental prosthesis molding block. The invention further relates to a method for producing a dental prosthesis part. In said method, a dental prosthesis molding block is provided, and the dental prosthesis part is produced by removing material from the dental prosthesis molding block using a CAD/CAM process. In doing so, a pin having a self-tapping external screw thread is created.

A system that includes a gingiva former, a final abutment, and a final implant replacement. The gingiva former includes connecting geometry for attachment to an implant, a customized edge, a tapered bottom portion, and a tapered top portion that includes a circumferential surface. The customized edge and the tapered bottom portion have respective shapes that correspond to a 3D data set of a region of the final abutment that includes and is below an edge of the final abutment. The circumferential surface and a longitudinal axis of the connecting geometry form an angle of inclination. The customized edge of the gingiva former either (i) corresponds to a gingival line of the final implant replacement or (ii) is at a distance from the gingival line of the final implant replacement such that the gingival line of the final implant replacement is above the edge of the gingiva former.

The invention relates to a method for constructing tooth surfaces of a dental prosthesis and for producing dental restorations, starting from a 3D data record of an upper mandible layout and a 3D data record of a lower mandible layout, each layout comprising a number of teeth arranged in each mandibular arch and the teeth of the upper mandible layout and the teeth of the lower mandible layout at intercuspation making contact with each other at multiple contact points. The contact surfaces are selected by approximation. Relevant surface pairs lying opposite one another are identified and are incorporated by an optimization algorithm into local minimum distances, taking into consideration surfaces that can slide past one another. This allows the desired contact points to be produced. Surfaces that have not been selected are not considered in the production of the points of contact.
