摘要： The dental prosthesis comprises a base from a durable corrosion-resistant metallic alloy and at least one external decorative layer. The external decorative layer is made of a harder material than the base and comprises nitrides, oxynitrides, carboxynitrides, cyanonitrides and/or oxides of metals of the subordinate subgroup of Group IV of the periodic system. The thickness ratio of the external decorative layer to the base is equal to 1:10-200 respectively.In the case where the dental prosthesis base comprises a structure of soldered members from a durable corrosion-resistant metallic alloy, the method for making the dental prosthesis comprises manufacture of the base by soldering members of the dental prosthesis from the abovementioned alloy into an integrated structure. Then the zone of the soldered juncture or the entire structure is coated, by electroplating or vacuum technique, with an additional layer from cobalt, nickel, molybdenum, chromium or zirconium, or from nitrides of chromium or molybdenum. The thickness ratio of the additional layer to the external decorative layer is equal to 0.5-1:1 respectively. Thereafter, the external decorative layer is deposited by vacuum technique.
