Abstract
The invention relates to a biomaterial for bony or dental fillings on the basis of apatite. It provides a biomaterial having antiseptic properties for limiting the proliferation of microorganisms at the site of implantation. The biomaterial according to the invention is based on calcium oxygenated phosphate having an apatitic structure which has oxygenated species with degrees of oxidation greater than or equal to -2. This biomaterial brings together with the antiseptic properties mentioned above an excellent biocompatibility, a very low solutility and good qualities of osteo-induction.
