Notes:
For commercialized dental implants, to enhance the bone bonding of the artificial toothroots, several kinds of surface modification techniques, such as hydroxy-apatite coating, anodicoxidation and sand-blasting, have been developed. Apart from the surface modification, it is knownthat the bone growth is accelerated by electric stimulations in the living body. In the present study, thegalvanic current between titanium substrate and gold coating partially on the titanium implants wasapplied 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 safter 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 suitablegalvanic current density enhancing calcium phosphate precipitation
