IMPLANTABLE BONE REPLACEMENT MATERIALS BASED ONCALCIUM PHOSPHATE CERAMIC MATERIAL IN A MATRIX ANDPROCESS FOR THE PRODUCTION THEREOFABSTRACT OF THE DISCLOSUREAn implantable bone replacement material (body) based oncompletely or partially resorbable particles incorporated in amatrix material. The particles are composed of bioactivesintered calcium phosphate ceramic material having a CaO:P2O5composition ratio between 3:1 and 4:1. The replacement material(body) consists of a metal containing calcium phosphate ceramicmaterial in the form of a monolayer of particles in theperipheral areas of the material (body) which serve as inter-faces to the body tissue. The metal is compatible with bodytissue. The ceramic particles have a size range between about500 µm and a few millimeters. The calcium phosphate particlesare located so that they lie exposed on the upper surface ofthe material (body). Other embodiments and processes are alsodisclosed.
