[0003] The invention relates to a real and a virtual 3D shaped intermediate for the production of an intermediate of a real or virtual prosthesis, in particular comprising hardened compositions A and B, preferably polymerized compositions A and B, as well as for the production of a real or virtual prosthesis. Furthermore, the invention relates to a method for generating the virtual 3D shaped intermediate and to a method, in particular a computer-implemented method, for producing the intermediate of a real prosthesis as well as the real prosthesis, in particular a real dental prosthesis. Also related to the invention is a data set of the 3D data model of the virtual 3D shaped intermediate, in particular comprising a computer program for producing the virtual and / or real 3D shaped intermediate.

[0004] The production of prefabricated tooth forms using industrial processes has been known for a long time. In these processes, a polymerizable composition is cured in production molds using thermal polymerization. The compositions typically consist of methacrylate compounds with a small proportion of inorganic fillers. Multi-layered prefabricated teeth can be produced in this way. However, production based on composite-like materials is only possible with considerable effort and expense. The production of tooth forms using material-building processes, such as additive manufacturing, is also possible. A disadvantage of this method is that only homogeneous tooth blanks can be produced. Furthermore, the production of tooth blanks using material-removing processes is possible, but here too, individual layering of tooth blanks is not feasible.

[0005] The object of the invention was to provide a method for producing complete dentures from different materials with individual aesthetics and optimized mechanical properties. Furthermore, the object was to enable the individualization of internal layers, for example, before the production of the dentin core or an internal core. Additionally, the object was to provide a method for producing multi-layered dentures, preferably dental prostheses, such as teeth, from radiation-cured compositions. The method should preferably be economically feasible both in dental laboratories and on an industrial scale. Likewise, the object was to avoid or improve the fit accuracy compared to prefabricated teeth produced using the aforementioned methods.

[0006] Computer-integrated manufacturing (CIM) processes, such as CAD / CAM procedures, are becoming increasingly important in dental prosthetics. It is now common practice, not only in implant prosthetics, to digitize the implant and remaining tooth situation in the patient's mouth and to design and manufacture the dental prosthesis using CAD / CAM. Similarly, it has become common practice to digitize the remaining tooth situation, occlusion, and / or cavities in teeth directly in the patient's mouth and to design and manufacture inlays, crowns, etc., using CAD / CAM.
