Static computer-assisted surgery (s-CAS) has been introduced to improve the results of implantology. A prospective cohort study was conducted following the STROBE guidelines to determine the presence of a learning curve in s-CAS. Six partially and six totally edentulous patients were treated by two surgeons experienced in implantology but completely inexperienced in s-CAS. Preoperative and postoperative computed tomography scans were matched to assess coronal, apical, and angular deviation and the positioning error. The accuracy data were used to evaluate the learning curve. Fifty-six implants were inserted. In partially and totally edentulous patients, the mean (range; standard deviation) coronal deviation was 0.87 (0.34-1.27; 0.35) and 1.24 (0.72-2.67; 0.79); the mean apical deviation was 1.13 (0.48-1.63; 0.39) and 1.52 (0.88-3.84; 1.15); the mean angular deviation was 2.63 (1.89-4.50; 0.98) and 3.59 (1.69-6.30; 1.65); and the mean positioning error was 0.80 (0.32-1.25; 0.35) and 1.14 (0.35-2.56; 0.77), respectively. A typical 'learning curve' effect was not identified for s-CAS.
静态计算机辅助手术（s-CAS）已被引入以改善种植体学的结果。本研究按照 STROBE 指南进行了前瞻性队列研究，以确定 s-CAS 是否存在学习曲线。由两位具有丰富种植体经验但完全没有 s-CAS 经验的外科医生对六名部分和六名完全无牙患者进行了治疗。对术前和术后计算机断层扫描进行匹配，以评估冠向、根尖和角向偏差以及定位误差。准确性数据用于评估学习曲线。共植入 56 个种植体。在部分和完全无牙患者中，冠向偏差的平均值（范围；标准差）分别为 0.87（0.34-1.27；0.35）和 1.24（0.72-2.67；0.79）；根尖偏差的平均值分别为 1.13（0.48-1.63；0.39）和 1.52（0.88-3.84；1.15）；角向偏差的平均值分别为 2.63（1.89-4.50；0.98）和 3.59（1.69-6.30；1.65）；定位误差的平均值分别为 0.80（0.32-1.25；0.35）和 1.14（0.35-2.56；0.77）。s-CAS 未出现典型的“学习曲线”效应。
