Two groups of titanium dental implants, identical in geometry but different in the treatment of their surfaces, were tested in an in vivo minipig model of the mandible. The surfaces that were tested were, first, sandblasted and acid-etched; and secondly, sandblasted, acid-etched, and conditioned. The removal torque was assessed at 2, 4, and 8 weeks after implantation (n=6 animals in each healing period). The interfacial stiffness was also evaluated. All dental implants were well-integrated at the time of death. Removal torque values increased significantly over the course of 8 weeks. Removal torque and interfacial stiffness were increased for conditioned surfaces after 2 weeks, but there were no significant differences between the two surfaces. The sandblasted and acid-etched implants are the standard, and conditioning of the surface showed a tendency to increase early peri-implant formation of bone.
两组几何形状相同但表面处理不同的钛牙种植体，在小型猪下颌骨的体内模型中进行了测试。测试的表面，首先是喷砂和酸蚀处理的；其次是喷砂、酸蚀和预处理的。在植入后2周、4周和8周评估去除扭矩（每个愈合期n = 6只动物）。还评估了界面刚度。所有牙种植体在处死时均已良好整合。去除扭矩值在8周内显著增加。预处理表面在2周后去除扭矩和界面刚度增加，但两种表面之间无显著差异。喷砂和酸蚀种植体是标准处理方式，表面预处理显示出早期种植体周围骨形成增加的趋势。
