Abstract
The coating for a prothesis system has a resorbability gradient in the direction perpendicular to the surface of the prothesis system, the internal layer being the least resorbable. It can consist of phospho-calcium material or of two or several successive layers having different resorbabilities and having said resorbability gradient. The prothesis systems covered with the coating according to the invention are used in surgery for the provision of thigh-bone protheses as well as protheses for the facial, ear, nose and throat surgery and the like.
