目的 评估缓冲磨削技术的有效性和并发症。主要结局是窦内骨增益（ESBG），次要结局包括施奈德膜穿孔率和中长期种植体存活率。材料和方法在这项回顾性研究中，我们将缓冲磨削技术与经典骨凿技术进行比较，建立统计模型来评估 ESBG、膜穿孔率和种植体存活率。结果 总共纳入 259 名患者和 340 个种植体。缓冲磨削组的平均 ESBG 为 5.31 毫米，骨凿组为 4.64 毫米。多变量回归分析显示，缓冲研磨技术显着促进 ESBG (p = .028)。 19 个准备部位出现膜穿孔，缓冲磨削组和骨刀组的发生率分别为 5.5% 和 6.4%。然而，差异并不具有统计显着性 (p = .920)。此外，种植体7年的累积存活率分别为95.2%和91.4%，手术技术对结果没有显着影响。结论 通过 6 个月至 7 年的修复体修复后审查数据，我们的研究结果表明，缓冲磨削技术有助于提高 ESBG，而膜穿孔或种植体失败率没有显着差异。
AIM To evaluate the effectiveness and complications of the cushioned grind-out technique. The primary outcome was endo-sinus bone gain (ESBG), while secondary outcomes included the Schneiderian membrane perforation rate and mid- to long-term implant survival. MATERIALS AND METHODS In this retrospective study, we compared the cushioned grind-out technique with the classic osteotome technique, establishing statistical models to assess ESBG, membrane perforation rate and implant survival rate. RESULTS A total of 259 patients and 340 implants were included. The mean ESBG was 5.31 mm for the cushioned grind-out group and 4.64 mm for the osteotome group. Multivariable regression analysis revealed that the cushioned grind-out technique significantly facilitated ESBG (p = .028). Nineteen preparation sites experienced membrane perforation, with rates of 5.5% and 6.4% for the cushioned grind-out and osteotome groups, respectively. However, the difference was not statistically significant (p = .920). Additionally, the cumulative survival rate of the implants for 7 years was 95.2% and 91.4%, respectively, with the surgical technique not significantly influencing the results. CONCLUSIONS With 6 months to 7 years of post-prosthetic restoration review data, our findings show that the cushioned grind-out technique facilitates a higher ESBG, with no significant difference in membrane perforation or implant failure rate.
