The purpose of this study was to research the osseointegration in the interface of dental gold alloy. Some investigator presented that gold was biologically safe but occurred fibrous integration on implant interface. We used 4 different gold composition implant to investigate the osseointegration on implant interface. Osseointegration occurred on the all implant interface. We thought that osseointegration depended not only on gold composition but also on precious metal composition such as platinum or silver. If we use precious metal implant, it might reduce the Galvanic current and chemical corrosion which were occurred between titanium implant and percious metal suprastructure. We recommend that precious metal implant was superior to non-precious metal implant without financial problem.
