To compare the accuracy of implant placement performed with either a surgical motor or a torque wrench as part of a half-guided surgical protocol.
Implant insertion with half-guided surgical protocol was utilized by surgical motor (machine-driven group) or torque wrench (manual group) in the posterior maxilla. After the healing period, accuracy comparison between planned and actual implant positions was performed based on preoperative cone beam computed tomography and postoperative digital intraoral scans. Coronal, apical, and angular deviations, insertion time, and insertion torque were evaluated.
Forty patients were treated with 1 implant each; 20 implants were inserted with a surgical motor and 20 implants with a torque wrench. Global coronal and apical deviations were 1.20 ± 0.46 mm and 1.45 ± 0.79 mm in the machine-driven group, and 1.13 ± 0.38 mm and 1.18 ± 0.28 mm in the manual group (respectively). The mean angular deviation was 4.82 ± 2.07° in the machine-driven group and 4.11 ± 1.63° in the manual group. Mean insertion torque was 21.75 ± 9.75 Ncm in the machine-driven group, compared to 18.75 ± 7.05 Ncm in the manual group. Implant placement duration was 9.25 ± 1.86 s in the machine-driven group at a speed of 50 rpm, and 36.40 ± 8.15 s in the manual group.
No significant difference was found between the two groups in terms of accuracy and mean insertion torque, while machine-driven implant placement was significantly less time-consuming.
Optimal implant placement accuracy utilized by half-guided surgical protocol can be achieved with both machine-driven and torque wrench insertion.

比较在半引导式手术方案中使用手术电机或扭力扳手进行种植体植入的准确性。
在后上颌利用半引导式手术方案使用手术电机（机器驱动组）或扭力扳手（手动组）植入种植体。在愈合期后，根据术前锥形束计算机断层扫描和术后数字口内扫描，比较计划和实际种植体位置之间的准确性。评估了冠向、根尖向和角度偏差、植入时间和植入扭矩。
40 名患者每人接受 1 个种植体治疗；20 个种植体使用手术电机植入，20 个种植体使用扭力扳手植入。机器驱动组的全局冠向和根尖向偏差分别为 1.20±0.46mm 和 1.45±0.79mm，手动组分别为 1.13±0.38mm 和 1.18±0.28mm。机器驱动组的平均角度偏差为 4.82±2.07°，手动组为 4.11±1.63°。机器驱动组的平均植入扭矩为 21.75±9.75Ncm，手动组为 18.75±7.05Ncm。机器驱动组的植入持续时间为 9.25±1.86s，转速为 50rpm，手动组为 36.40±8.15s。
两组在准确性和平均植入扭矩方面没有显著差异，而机器驱动的种植体植入明显更省时。
半引导式手术方案可实现最佳种植体放置精度，可使用机器驱动和扭力扳手植入。
