在兔牙种植模型上，比较了新型氧化锆/氧化铝复合陶瓷种植体材料（Y，Nb）-TZP/氧化铝与传统钛种植体的骨整合率。分别于4周和6周愈合后对4组螺纹种植体进行比较。通过不脱钙组织切片评价骨种植体接触率和骨体积。扫描电镜下观察各组种植体表面形态。在本研究的限制范围内，与钛植入物相比，Zr/Al复合陶瓷植入物表现出良好的骨反应。这种材料证明了钛牙科种植体替代品的可能性。需要进一步的研究来证实这一结果。
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.
