A material for restoring bone tissue is provided to high bonding strength between a screw and bone which has insufficient strength like osteoporosis. A material(10) for restoring bone tissue is made of sintered body of a calcium phosphate compound or hardened body. Sintered body or hardened body has strength to support a shape, before insertion and under the insertion of the sintered body or the hardened body into a drill hole(21). The calcium phosphate compound is made of the sintered body of hydroxyapatite. The pore is 40-80%. A diameter of the calcium phosphate compound is 1.5-5.0mmPhi. |
