摘要 PCT No. PCT/EP88/00711 Sec. 371 Date Feb. 20, 1990 Sec. 102(e) Date Feb. 20, 1990 PCT Filed Aug. 9, 1988 PCT Pub. No. WO89/01347 PCT Pub. Date Feb. 23, 1989.According to a process for producing a bone replacement material, natural bones are used as raw material, the soft parts of the bones are removed, as well as any residual organic substances, and the remaining osseous substance is finally sintered at temperatures between 1100 degrees and 1500 degrees Celcius. In order to simplify such a process and to ensure a more gentle processing of the inorganic bone matrix, the bones are dried at an increased temperature, maximum 550 degrees Celcius, with a reduced air supply or in a reducing atmosphere, then the temperature of the bones is increased during the following step up to 750 degrees to 800 degrees Celcius, with an increased air supply, and finally the bones are sintered.
