The aim of this study was to systematically review the current scientific literature regarding the accuracy of fully guided flapless implant positioning for complete-arch rehabilitations in edentulous patients and to assess if there was any statistically significant correlation between linear deviation at shoulder point, at apex point and angular deviation. The electronic and manual literature search of clinical studies was carried out using specified indexing terms. A total of 13 studies were eligible for qualitative analysis and 277 edentulous patients were rehabilitated with 1556 implants patients by means of fully guided mucosa-supported template-assisted flapless surgery. Angular deviation was 3.42° (95% CI 2.82-4.03), linear deviation at shoulder point 1.23 mm (95% CI 0.97-1.49) and linear deviation at apex point 1.46 mm (95% CI 1.17-1.74). No statistically significant correlations were found between the linear and angular deviations. A statistically significant correlation was found between the two linear deviations (correlation coefficient 0.91) that can be summarized by the regression equation y = 0.03080 + 0.8254x. Computer-assisted flapless implant placement by means of mucosa-supported templates in complete arch restorations can be considered a reliable and predictable treatment choice despite the potential effects that flapless approach could bring to the overall treatment.
本研究的目的是系统回顾当前关于无牙颌患者全牙弓修复中完全引导式无瓣种植体定位准确性的科学文献，并评估肩点、根尖点的线性偏差与角度偏差之间是否存在任何统计学上的显著相关性。使用特定的索引词对临床研究进行了电子和手工文献检索。共有13项研究符合定性分析标准，277例无牙颌患者通过完全引导式黏膜支持模板辅助无瓣手术用1556颗种植体进行了修复。角度偏差为3.42°（95%可信区间2.82 - 4.03），肩点线性偏差为1.23 mm（95%可信区间0.97 - 1.49），根尖点线性偏差为1.46 mm（95%可信区间1.17 - 1.74）。线性偏差和角度偏差之间未发现统计学上的显著相关性。在两个线性偏差之间发现了统计学上的显著相关性（相关系数0.91），可由回归方程y = 0.03080 + 0.8254x概括。尽管无瓣方法可能会给整体治疗带来潜在影响，但在全牙弓修复中通过黏膜支持模板进行计算机辅助无瓣种植体植入可被视为一种可靠且可预测的治疗选择。
