Histomorphometric Analysis of Zirconia/Alumina Composite and CP Titanium Treaded Implants in Rabbit Tibia

Article Preview

The osseointegration rate of a new zirconia/alumina composite ceramic implant material, (Y,Nb)-TZP/ alumina, was compared with conventional titanium implant in the rabbit model. Four different groups of threaded implant were compared after 4 and 6weeks healing period. The bone implant contact ratio and bone volume was evaluated by undecalcified histologic sections. The surface of each implant group was observed under SEM. Within the limitations of this study, Zr/Al composite ceramic implants demonstrated favorable bone response compared to titanium implant. This material demonstrated a possibility of an alternative to titanium dental implant. Further studies are needed to confirm this result.
