摘要:
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.
