ObjectivesTo evaluate and compare the accuracy of task‐autonomous robot‐assisted implant surgery (RAIS) and dynamic computer‐assisted implant surgery (dCAIS) for zygomatic implant placement.Materials and MethodsTen atrophic edentulous maxilla models requiring zygomatic implant (ZI) placement were randomly divided into the RAIS and dCAIS groups. Osteotomies and implant placement were performed under the guidance of a task‐autonomous robotic system or dynamic navigation system. A total of 20 ZIs were analyzed. The angular, coronal, lateral coronal, coronal depth, apical, lateral apical, and apical depth deviations were measured and analyzed between the two groups. The primary outcome parameters were the angular deviations between the planned and the placed ZIs. Data was subjected to descriptive and comparative statistical analysis. The significance of inter‐group differences for continuous variables was assessed with Student's two‐sample t‐tests, Welch two‐sample t‐tests, and Mann–Whitney U tests according to the distribution normality and variance homogeneity.ResultsZI placement deviations were compared between the RAIS and dCAIS groups, showing a mean angular deviation of 0.92 ± 0.40° versus 2.03 ± 0.53° (p < 0.001), a mean (±SD) coronal deviation of 0.48 ± 0.25 mm versus 1.29 ± 0.46 mm (p < 0.001), and a mean apical deviation of 0.88 ± 0.28 mm versus 1.96 ± 0.46 mm (p < 0.001).ConclusionsFor computer‐guided ZI placement, task‐autonomous RAIS was superior to dCAIS in terms of accuracy.

使用任务自主机器人系统或动态导航放置颧骨植入物的准确性：一项体外研究


目的评价和比较任务自主机器人辅助种植手术 （RAIS） 和动态计算机辅助种植手术 （dCAIS） 在颧骨种植体植入中的准确性。材料与方法将 10 例需要颧骨植入物 （ZI） 植入的萎缩无牙上颌骨模型随机分为 RAIS 组和 dCAIS 组。截骨术和植入物植入在任务自主机器人系统或动态导航系统的指导下进行。共分析 20 个 ZI。测量和分析两组之间的角度、冠状、侧冠状、冠状深度、顶端、外侧顶端和顶端深度偏差。主要结局参数是计划和放置的 ZI 之间的角度偏差。数据进行描述性和比较统计分析。根据分布正态性和方差同质性，使用 Student 双样本 t 检验、Welch 双样本 t 检验和 Mann-Whitney U 检验评估连续变量的组间差异的显著性。结果比较 RAIS 组和 dCAIS 组之间的 ZI 放置偏差，显示平均角度偏差为 0.92 ± 0.40° 与 2.03 ± 0.53° （p < 0.001），平均 （±SD） 冠状偏差为 0.48 ± 0.25 mm 与 1.29 ± 0.46 mm （p < 0.001），平均顶端偏差为 0.88 ± 0.28 mm 与 1.96 ± 0.46 mm （p < 0.001）。结论对于计算机引导的 ZI 放置，任务自主 RAIS 在准确性方面优于 dCAIS。
