Neue Beschichtung für Prothesen

摘要

The coating for a prosthesis system exhibits an absorption/replacement gradient in the direction perpendicular to the surface of the prosthesis system, the inner layer being the least absorbable. It can be made from calcium phosphate materials or else from two or more successive layers of differing absorption/replacement exhibiting the said absorption/replacement gradient. The prosthesis systems covered with the coating according to the invention are used in surgery for producing femoral prostheses, maxillofacial prostheses, ENT prostheses or other prostheses.
