Abstract

Objective

This study aimed to compare the accuracy of an autonomous robotic system for anterior immediate and delayed implant placement.

Methods

This retrospective study included patients who underwent anterior dental implant surgery from September 2022 to March 2025 using an autonomous robotic system. Osteotomies performed with the autonomous robotic system in this study were modified by using precision and side-cutting drills, along with repeated lifting of drills to minimize deviations. Linear and angular deviations in two- and three-dimensional space were assessed by matching preoperative planning with postoperative cone beam computed tomography. Postoperative pain and surgical satisfaction were recorded using a 100-mm visual analog scale. The Shapiro–Wilk test, Student's t-test, Mann–Whitney U-test, Pearson's Chi-Square test, and Fisher's exact test were used, and p < 0.05 was considered statistically significant.

Results

This retrospective study included 53 patients (65 implants) who underwent anterior dental implant surgery with the autonomous robotic system (immediate implant placement group: 19 patients, 21 implants; delayed implant placement group: 34 patients, 44 implants). Comparison of deviations in immediate and delayed implantation using the autonomous robotic system showed a mean (± SD) coronal deviation of 0.57 ± 0.19 mm versus 0.49 ± 0.20 mm (p = 0.129), a mean apical deviation of 0.57 ± 0.19 mm versus 0.52 ± 0.21 mm (p = 0.373), and a mean angular deviation of 0.53° ± 0.18° versus 0.61° ± 0.28° (p = 0.742). Postoperative pain and surgical satisfaction were not significantly different between the two groups (p > 0.05).

Conclusions

The autonomous robotic system demonstrated high and comparable accuracy in both anterior immediate and delayed implantation, with overall patient satisfaction. This could reduce the technical sensitivity of anterior immediate implant placement, enhance precision, and broaden the clinical applications of the autonomous robotic system.

使用自主机器人系统进行前路即刻植入与延迟植入的准确性：一项回顾性研究

目的本研究旨在比较自主机器人系统用于前路即刻和延迟种植体放置的准确性。方法回顾性研究纳入了2022年9月至2025年3月使用自主机器人系统进行前牙种植手术的患者。在本研究中，使用自主机器人系统进行的截骨手术通过使用精密和侧切钻头进行改进，并反复提起钻头以尽量减少偏差。通过术前规划与术后锥形束计算机断层扫描相匹配来评估二维和三维空间的线性和角度偏差。术后疼痛和手术满意度用100毫米视觉模拟量表记录。采用Shapiro-Wilk检验、Student’st检验、Mann-Whitney u检验、Pearson’s Chi-Square检验和Fisher’s精确检验，p <； 0.05为差异有统计学意义。结果本回顾性研究包括53例（65颗种植体）采用自主机器人系统行前牙种植手术(即刻种植组19例，21颗种植体；延期种植组：34例，种植体44颗)。采用自主机器人系统对即刻植入和延迟植入的偏差进行比较，冠状面平均偏差（±SD）为0.57±0.19 mm对0.49±0.20 mm (p = 0.129)，根尖平均偏差为0.57±0.19 mm对0.52±0.21 mm (p = 0.373)，平均角度偏差为0.53°±0.18°对0.61°±0.28°（p = 0.742）。两组患者术后疼痛和手术满意度差异无统计学意义（p > 0.05）。结论自主机器人系统在前牙即刻种植和延期种植中均表现出较高的准确度，患者总体满意。这可以降低前路即刻植入的技术敏感性，提高精度，扩大自主机器人系统的临床应用。
