For commercialized dental implants, to enhance the bone bonding of the artificial tooth roots, several kinds of surface modification techniques, such as hydroxy-apatite coating, anodic oxidation and sand-blasting, have been developed. Apart from the surface modification, it is known that the bone growth is accelerated by electric stimulations in the living body. In the present study, the galvanic current between titanium substrate and gold coating partially on the titanium implants was applied to enhance calcium phosphate precipitation in a pseudo-body fluid namely Hanks' solution. The galvanic current between titanium specimens and gold electrode jumped up approximately 0.2 s after put into Hanks' solution and the current has decreased asymptotically. With such consideration, the desirable conditions of surface modification by gold coating were presented to provide suitable galvanic current density enhancing calcium phosphate precipitation.
