The method is used for making a dental prosthesis or for the adaptation of an existing dental prosthesis for the inclusion in and attachment to existing residual dentition and/or at least one implant. Here, individual teeth and/or implants and/or the remains thereof form the anchor elements for anchoring the dental prosthesis. First, an imprint of the actual condition of the jaw of the patient occurs, from which a master model and a working model are molded. Then, the working model is adjustably fixed in a milling base and aligned with respect to the insertion direction in a milling machine or parallelometer. Next, adhesion surfaces (2) made from wax in the manner of wide-area brackets, an adhesive bridge or the like are molded onto the molded anchor elements (1). Then a molded connecting part (3) with a permanently attached parallelization pin (4) and/or retention anchor element is waxed thereon after successful alignment with the insertion direction by means of the parallelization pins (4). Subsequently either the teeth (7) forming the dental prosthesis, the cast-model framework (8) and further necessary parts are modeled in wax, or the already an existing dental prosthesis are modeled on. Finally the model is provided with injection molding passages (9), and for this purpose each of the elements is worked on individually. Then, the model is embedded and boiled out for removing the wax, and that finally after insertion of the interchangeable matrix (duplicating matrix) into the molded connecting part (3) and surface treatment of the mold inner surfaces and the plaster mold, the mold is removed, followed by the removal of the dental prosthesis.

The invention relates to a method for the preparation of a blank of a ceramic material, wherein a first ceramic material and then a second ceramic material of different compositions are filled into a die and wherein the materials are pressed and after pressing are sintered. A layer of the first ceramic material is thereby filled into the die and a first cavity formed in the layer, the second ceramic material is then filled into the first open cavity and the materials pressed together and then heat-treated.

A dental prosthesis is disclosed includes a prosthetic tooth element comprising ceramic and a veneer located on a surface of the prosthetic tooth element, the veneer comprising cured dental composite. The prosthetic tooth element can be fixed to a mount in a patient's mouth using the same dental composite used for the veneer. A method of forming a prosthetic tooth element is disclosed including filling a mould that is formed at least partially from flexible polymeric material with a dental mixture comprising ceramic, and applying pressure to the filled mould to form a prosthetic tooth element comprising ceramic with a roughened surface.
