This study evaluated the early biomechanical fixation and bone-to-implant contact (BIC) of an alumina-blasted/acid-etched (AB/AE) compared with an experimental resorbable blasting media (RBM) surface in a canine model. Higher texturization was observed for the RBM than for the AB/AE surface, and the presence of calcium and phosphorus was only observed for the RBM surface. Time in vivo and implant surface did not influence torque. For both surfaces, BIC significantly increased from 2 to 4 weeks.
本研究在犬类模型中评估了氧化铝喷砂/酸蚀(AB/AE)表面与实验性可吸收喷砂介质(RBM)表面相比的早期生物力学固定和骨与种植体接触(BIC)情况。观察到RBM表面的纹理化程度高于AB/AE表面,且仅在RBM表面检测到钙和磷的存在。体内时间和种植体表面对扭矩没有影响。对于这两种表面,BIC在2至4周时均显著增加。
