Amorphous calcium phosphate (ACP), oxyapatite (Ca_<10>(PO_4)_6O, OAp), heat-treated OAp (OAp-AIR) and OAp/OAp-AIR double layer (D-layer) coating films were fabricated on the surface of the titanium substrates using RF magnetron sputtering. The cross sectional observation before and after the implantation, bonding strength between coating film and substrates and removal torques from femur of Japanese white rabbits were examined. The bonding strength between coating films and substrates were more than 50 MPa, and removal torque of coated implants from the femur of Japanese white rabbits were greater than that of uncoated one. After the implantation of ACP coating film, the coating would be dissolved into the body and it caused the high biocompatibility of bone.
