分析使用（经牙槽骨）骨凿技术安装种植体的存活率和成功率，比较骨凿安装种植体与使用标准外科手术植入种植体的种植体周围软组织参数和边缘骨水平，并评价以患者为中心的结局。在2000年至2005年期间，在181名患者中植入了252个Straumann（（R））牙科种植体。手术技术是对Summers提出的原始骨凿技术的改进。除了临床检查外，还要求患者利用视觉模拟量表表达他们对手术过程的看法。平均随访3.2年后，安装骨凿的植入物的累积生存率为97.4%（95%置信区间：94.4-98.8%）。在插入的252个种植体中，3个在加载前丢失，另外3个在第一年和第二年丢失。根据剩余骨高度，
To analyze the survival and success rates of implants installed utilizing the (transalveolar) osteotome technique, to compare peri-implant soft tissue parameters and marginal bone levels of osteotome-installed implants with implants placed using standard surgical procedures, and to evaluate patient-centered outcomes.During 2000 to 2005, 252 Straumann((R)) dental implants were inserted in 181 patients. The surgical technique was a modification of the original osteotome technique presented by Summers. In addition to the clinical examination, the patients were asked to give their perception of the surgical procedure, utilizing a visual analogue scale.The cumulative survival rate of the osteotome-installed implants after a mean follow-up time of 3.2 years, was 97.4% (95% confidence intervals: 94.4-98.8%). From the 252 implants inserted, three were lost before loading and another three were lost in the first and second year. According to residual bone height the survival was 91.3% for implant sites with
