This clinical retrospective study aimed to compare the deviations in single-tooth implant placement using novel semi-autonomous robotic-assisted surgery system (sa-RASS) and dynamic navigation system (DNS) methods.
A retrospective analysis of medical records from January to December 2023 was conducted to compare the implantation accuracy of the sa-RASS and DNS in partially edentulous patients using cone-beam computed tomography. Platform, apex, and angular deviations were measured and analyzed. The Kolmogorov-Smirnov test was used to check the data distribution, along with t-tests or Mann-Whitney U-tests, where appropriate.
Fifty-seven patients (57 implants) were analyzed: 29 (29 implants) in the sa-RASS group and 28 (28 implants) in the DNS group. The comparison of platform, apex, and angular deviation between the sa-RASS group and DNS group were 0.91 ± 0.46 mm vs. 1.26 ± 0.51 mm (p < 0.001), 1.06 ± 0.60 mm vs. 1.51 ± 0.56 mm (p < 0.001), and 3.07° ± 1.66° vs. 3.71° ± 1.64° (p > 0.05), respectively. In addition, there was no significant difference in the accuracy of different implant regions (premolar, molar, maxilla, and mandible) or implant length (p > 0.05).
In the present study, sa-RASS implant placement showed better positional accuracy than DNS implant placement in platform and apex deviation, although these improvements in accuracy may have limited clinical relevance, suggesting that the sa-RASS might be advantageous in dental implant surgery.

本临床回顾性研究旨在比较使用新型半自动机器人辅助手术系统（sa - RASS）和动态导航系统（DNS）方法进行单颗牙种植体植入时的偏差。
对2023年1月至12月的病历进行回顾性分析，使用锥形束计算机断层扫描比较sa - RASS和DNS在部分牙列缺损患者中的植入准确性。测量并分析平台、根尖和角度偏差。使用Kolmogorov - Smirnov检验检查数据分布，并在适当情况下使用t检验或Mann - Whitney U检验。
分析了57例患者（57颗种植体）：sa - RASS组29例（29颗种植体），DNS组28例（28颗种植体）。sa - RASS组和DNS组之间的平台、根尖和角度偏差比较分别为0.91±0.46毫米对1.26±0.51毫米（p<0.001），1.06±0.60毫米对1.51±0.56毫米（p<0.001），以及3.07°±1.66°对3.71°±1.64°（p>0.05）。此外，不同种植区域（前磨牙、磨牙、上颌和下颌）或种植体长的准确性无显著差异（p>0.05）。
在本研究中，sa - RASS种植体植入在平台和根尖偏差方面显示出比DNS种植体植入更好的位置准确性，尽管这些准确性的提高可能具有有限的临床相关性，这表明sa - RASS在牙种植手术中可能具有优势。
