When producing tooth replacements from metal, the conventional method of casting is almost exclusively employed, even though said method is a relatively complicated one. The object of the invention is therefore to make available a method that is considerably simpler. In this method, an aqueous suspension, still containing microcrystalline wax and ethoxylated alcohols, is generated with the dental-grade metal powder. The metal powder is deposited on a model by electrophoresis, resulting, for example, in the formation of a cap (4). This cap (4) is filled with investment compound (5) and placed on a firing support (6), where it is sintered in this position. A cap is obtained which, in terms of its strength characteristics, is the equal of a cap that has been produced by casting. Alternatively, the cap (4) can be stabilized, during sintering, on a plated stump or in a muffle filled with a temperature-resistant powder.
