Apatite coating on orthopedic and dental implants contributes to fixation of implants to bone. To bond apatite on the implants with good bonding strength, plastic carbonateapatite (CHAP) ceramics were prepared and implanted in cavities on the surface of pure titanium implant. The CHAP ceramics were held firmly in the cavities by the implantation. The CHAP-implanted titanium was implanted in mandibles of female mongrel dogs. After 4 weeks, fibrous tissue become thinner and remarkable new bone formation was observed in the implantation cavities facing toward the CHAP implanted surface, while fibrous tissue around titanium surface still remains thick. The CHAP implantation was considered to provide favorable condition for the long-term stable fixation of the implants.
