PROBLEM TO BE SOLVED: To provide a bone tissue regeneration guiding membrane which is excellent in operability, moldability, and shape keeping stability for bone regeneration at an operation site upon damage or fracture of a bone and is fixed to shield an infected part and guides bone regeneration. SOLUTION: This bone tissue regeneration guiding membrane is constituted of at least a double layer membrane. The outer layer membrane is constituted of a material with modulus of rigidity 500-5,000 MPa at room temperature and glass transition temperature within the range 40-60 deg.C and the inner layer a material with modules of rigidity 2.0-500 MPa and glass transition temperature within the range 4-37 deg.C. A whole of the bone tissue regeneration guiding membrane has modulus of rigidity within the range 500-2,000 MPa at 4-40 deg.C. |
