静态计算机辅助手术（s-CAS）已被引入，以改善种植的结果。遵循StroBE指南进行了一项前瞻性队列研究，以确定s-CAS中是否存在学习曲线。六个部分和六个完全无牙颌患者由两名外科医生在种植体经验丰富，但完全没有经验的s-CAS。匹配术前和术后计算机断层扫描，以评估冠状面、根尖和角度偏差以及定位误差。准确度数据用于评估学习曲线。植入了五十六个种植体。在部分和全部无牙颌患者中，（范围;标准差）冠状面偏差为0.87（0.34-1.27; 0.35）和1.24（0.72-2.67; 0.79）;平均心尖偏离为1.13（0.48-1.63; 0.39）和1.52（0.88-3.84; 1.15），平均角偏差为2.63平均定位误差分别为0.80（0.32-1.25; 0.35）和1.14（0.35-2.56; 0.77）。未发现s-CAS的典型“学习曲线”效应。
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.
