The invention relates to a process for producing a bone-regeneration material. According to the method, a bio-compatible, open-pored body is exposed to a vacuum and osteoinductive and/or osteogenic substances are absorbed into the pores of the body, for example by means of a vacuum generated therein. It is thus possible to produce a bone-regeneration material, which contains osteoinductive and/or osteogenic substances in the pores of the bio-compatible body, said substances acting as a network structure for new somatic cells that are to grow into the porous body.
