Process for the manufacture of prosthetic elements and elements produced thereby
First Claim
1. A process for making a dental or maxillo-facial prosthesis comprising depositing, by electrochemical deposition of pure aluminum with a non-aqueous electrolyte base having an aluminiumorganic complex bath, a layer of pure aluminum on a conductive substrate, the substrate comprising a core of the prosthesis, and oxidizing the layer of aluminum by anodization to obtain a layer of alumina.

Abstract
Process for the manufacture of dental or maxillo-facial prostheses, particularly endo-osseous prostheses or pivots, in which a layer of pure aluminum is deposited on a conductive substrate, preferably a metal, which forms the core of the prosthesis. The aluminum layer is obtained by electrochemical deposition of pure aluminum with non-aqueous electrolyte base of the type which has an aluminumorganic complex bath. The layer is then oxidized by anodization such that an alumina layer which is sealed and electrically insulated, is obtained, separating the core and the biological tissues surrounding the prosthesis.
