Implantation of the Bioceramic sapphire implant® into the jaw has been very available in clinics.
But, unfortunately the success rate of this implant does not seem to be high in comparison with osseointegrated type implants. So we paid attention to the characteristic biocompatibility of the hydroxyapatite(HA) and devised the HA-coating on the surface of the screw grooves of the Bioceramic sapphire implant®(Apatite-coated Sapphire).Therefore, the purpose of this investigation was to observe the effect of HA-coating under the light microscope during an experimental study with dog mandibles. Microscopically, the HA-coated grooves of the screw was in contact with regenerative bone. In contrast with the grooves, the bare thread of the screw did not appear to be in contact with bone tissue. The results indicate that stability and success of Apatite-coated Sapphire may be possible.
