BIOLOGICAL MATERIALS

摘要

A biological material containing calcium phosphate and a lactic acid/glycoli c acid/.epsilon.-caprolactone copolymer. A biological material for inducing bo ne regeneration characterized in that a periost is attached to a biological material containing calcium phosphate and a lactic acid/glycolic acid/.epsilon.-caprolactone copolymer. A biological material for preventing adhesion containing calcium phosphate and a lactic acid/glycolic acid/.epsilon.-caprolactone copolymer wherein the composition ratio by mol o f lactic acid : glycolic acid : .epsilon.-caprolactone is 5-90 : 3-75 : 5-40 % by mol.
