| Research Abstract |
In vivo and in vitro evaluations of an amorphous calcium phosphate film formed on commercially pure titanium were conducted. Titanium implants coated with amorphous calcium phosphate were given to the femur and tibia of white rabbits. The implant stability quotient (ISQ) and bone implant contact for titanium implants were statistically improved by the coating of amorphous calcium phosphate. The coating film was absorbed during an implantation period of two-weeks; the release of Ca and P-related ions due to this absorption was suggested to play an important role in the improvement of bone compatibility. Further, the addition of Nb to the amorphous calcium phosphate film was an effective technique to control its resorbability in biological environments.
