Abstract

The invention relates to at least partly resorbable materials for replacing and/or joining bones and auxiliaries for implanting prosthesis material in living bone tissue which contain as their essential components body-compatible ceramic materials in admixture with body-resorbable oligomers and/or polymers of lower hydroxycarboxylic acids, more particularly glycolic acid and/or lactic acid (resin component) and which are characterized in that the resin component is produced using molecular-weight-regulating co-reactants from the class of mono- or polyfunctional carboxylic acids or corresponding alcohols and is substantially freed from free carboxyl groups.
