Abstract

In order to accelerate the speed of titanium implant osseointegration, titanium substrates were polished by silicon carbide abrasive papers and treated by sodium hydroxide solution. The treated titanium substrates were immersed in simulated body fluid at 37 C for several days, through bio-simulated mineralization, bioactivity apatite polycrystalline form on the titanium surface. The apatite polycrystalline were observed by scanning electron microscope to investigate surface morphology and size. Average grain size and grain distance were statistical. The pH value of simulated body fluid was measured by precise acidimeter. Also formation condition and process were discussed. The results of this study have verified certain distribution apatite polycrystalline, which grain distance less than osteocytes dimension(10-30 m), were prepared on titanium surface by controlling titanium surface roughness and sodium hydroxide concentration and immersion time.
