A retrospective analysis was done comparing the success rate of osseointegration at stage 2 of implants placed under "sterile" versus "clean" conditions. "Sterile" surgery took place in an operating room setting with strict sterile protocol. "Clean" surgery took place in a clinic setting with the critical factor that nothing touched the surface of the implant until it contacted the prepared bone site. A total of 273 implants in 61 cases were placed under sterile conditions with a fixture success rate of 98.9% and a case success rate of 95.1%; 113 implants were placed under clean conditions in 31 cases with a fixture and case success rate of 98.2% and 93.5%, respectively as judged clinically at stage 2. The difference in the success rates was not statistically significant. The results of this analysis indicate that implant surgery can be performed under both "sterile" and "clean" conditions to achieve the same high rate of clinical osseointegration.
进行了一项回顾性分析，比较了在“无菌”与“清洁”条件下植入种植体第二阶段的骨结合成功率。“无菌”手术在遵循严格无菌方案的手术室环境中进行。“清洁”手术在诊所环境中进行，关键在于在种植体接触准备好的骨部位之前，没有任何东西接触到种植体表面。在无菌条件下，共对61例患者植入了273枚种植体，种植体成功率为98.9%，病例成功率为95.1%；在清洁条件下，对31例患者植入了113枚种植体，根据第二阶段的临床判断，种植体和病例成功率分别为98.2%和93.5%。成功率的差异无统计学意义。该分析结果表明，种植手术可以在“无菌”和“清洁”条件下进行，以实现相同的高临床骨结合率。
