A bone replacement material comprises a tridimensional supporting structure comprised of elementary bodies which are interconnected and which define intermediate spaces, a coating mass comprised of filling bodies based on calcium compounds, as well as a binder (matrix). The binder and the filling bodies are resorbable, the filling bodies consisting of extremely porous spherical particles having a diameter comprised between 15 and 50 $g(m)m and a porous volume comprised between 50 and 80% to which fibre material may be partially mixed. The bone replacement material is appropriate to produce coating layers of prosthesis which become anchoring parts for said prosthesis. It may also be used to fabricate a complete implant. |
