ABSTRACT:
A biocompatible titanium implant with a modified exterior surface having a covering layer that comprises a hydrated titania gel. The exterior surface of the titanium implant is processed by a hydrogen peroxide aqueous solution that contains metal ions which not only promotes a reaction between the titanium implant and the hydrogen peroxide aqueous solution but also provides a high apatite formation ability to the hydrated titania gel on the surface of the implant.
