Abstract

The dental prosthesis comprises a base of a durable corrosion-resistant metallic alloy and an external decorative layer is made of a harder material than the base and comprises one or more compounds selected from the nitrides, oxynitrides, carboxynitrides, cyanonitrides, and oxides of metals of the subordinate subgroup of Group IV of the periodic system. preferably Ti and Zr. The thickness ratio of the external decorative layer to the base is 1:10-200 respectively. In the case where the base comprises a structure of soldered members made of a durable corrosion-resistant metallic alloy, the zone of the soldered juncture or the entire structure is coated, by electroplating or vacuum technique, with an additional layer of cobalt, nickel, molybdenum chromium, or zirconium, or nitrides of chromium or molybdenum. The thickness ratio of the additional layer to the external decorative layer is 0.5-1:1 respectively. Thereafter, the external decorative layer is deposited by vacuum technique.
