This study compared the removal torque between injection molded zirconia implants and titanium implants with resorbable blast media (RBM) surfaces in beagle humeri. Fifteen screw-shaped implants were classified into 3 groups; titanium implant with RBM surface (Group RT), injection molded zirconia implant (Group Zr) and injection molded zirconia implant with sand-blasted surface (Group ZrS). Implants were inserted into beagle humeri. After 12 weeks, removal torque values were measured. The Zr group has a slightly higher removal torque value than the RT and ZrS groups but there were no significant differences among groups. Zirconia implants shows a similar removal torque to RBM titanium implants. This in vivo study showed injection molded zirconia implants could be an alternative to RBM titanium implants in terms of removal torque.
本研究比较了注射成型氧化锆种植体与具有可吸收喷砂介质（RBM）表面的钛种植体在比格犬肱骨中的拆除扭矩。将15枚螺旋形种植体分为3组；具有RBM表面的钛种植体（RT组）、注射成型氧化锆种植体（Zr组）和具有喷砂表面的注射成型氧化锆种植体（ZrS组）。将种植体植入比格犬肱骨。12周后，测量拆除扭矩值。Zr组的拆除扭矩值略高于RT组和ZrS组，但各组之间无显著差异。氧化锆种植体的拆除扭矩与RBM钛种植体相似。这项体内研究表明，就拆除扭矩而言，注射成型氧化锆种植体可以替代RBM钛种植体。
