Abstract

The invention relates to an implant material which is based on a composite material of calcium phosphate ceramic particles and bioabsorbable polymer, in which the proportion of calcium phosphate ceramic particles is at least 50% by weight and the particles are joined to one another by polymer bridges to give a three-dimensional open-pore structure in which the particle surfaces are covered with polymer to the extent of not more than 50%. This implant material is distinguished by particularly favorable growing-in and healing-in properties.
