PROBLEM TO BE SOLVED: To fix and cover a bone defect site to shield soft tissue invasion, to control the strength and decomposability until bone regeneration in a membrane material for inducing bone regeneration, and to further shorten the bone regeneration period. An osteoinductive regenerative membrane material is provided. [MEANS FOR SOLVING PROBLEMS] At least one surface of a film composed of a complex comprising a terpolymer of lactic acid / glycolic acid / ε-caprolactone and a calcium phosphate material as main components is coated with calcium phosphate material or by means such as adhesion. The surface-treated osteoinductive regenerative membrane material is used with its surface-treated surface coated so as to face the inside of the bone defect site. [Selection] Figure 3 |
