ABSTRACT:
Bone replacement or prosthesis anchoring material on the basis of sintered calcium phosphates which consists of a mixture of calcium phosphates with low or high-molecular-weight organic substances. More specifically, the anchoring material consists of a mixture of calcium phosphates composed of CaO and P.sub.2 O.sub.5 in a quantitative ratio of 2:1 to 4:1 with biodegradable polymers in a ratio of 10:1 to 1:1 of phosphate to polymer and is implantable as a solid body. A method for the production of the material wherein calcium phosphate with a porosity of 15 to 30 volume percent is used and its pores are filled by impregnation with polymer material.
