Abstract

Objectives

This study evaluated the effectiveness of force-feedback–based autonomous dental implant robotic systems combined with osseodensification (OD) for transcrestal sinus floor elevation (TSFE), to understand patterns of force-feedback curves, visualize the TSFE process through mechanical vision, and offer new perspectives on surgical strategies.

Materials and Methods

The included patients required simultaneous implant placement and TSFE. Preoperative planning was performed, and during surgery, using an OD drill, the robotic arm was guided to create a microfracture on the sinus floor, elevate the sinus membrane, and place the implant, all under the surgeon's supervision. Postoperative cone-beam computed tomography evaluated sinus lift and implant accuracy. The visual analog scale was used to measure patient-reported outcomes. Mechanical curves were plotted using extracted force-feedback values. Data are reported as mean ± standard deviation and Pearson's correlation for linear relationships (p < 0.05 was statistically significant).

Results

Overall, 17 patients (18 implants) were included, with a 94.4% implant retention rate at 6 months postoperatively. The Fz force-feedback curve showed a critical peak followed by a sharp drop at the sinus-floor breakthrough point and a gradual rise followed by a steep decrease as the bone graft entered the sinus cavity. Cortical bone density at the sinus floor positively correlated with force feedback (p < 0.05).

Conclusions

Force-feedback–based implant robotics combined with OD is an innovative and reliable approach for TSFE. Integrating mechanical vision with force-feedback curves allows for precise identification of microfracture points and safe sinus membrane elevation, overcoming the limitations of traditional blind techniques and enhancing procedural safety and predictability.

力反馈植入机器人与骨密度钻孔经瓣窦底抬高：回顾性病例系列研究。

目的：本研究评估基于力反馈的自主种植体机器人系统结合骨密度（OD）进行经牙窦底抬高（TSFE）的有效性，了解力反馈曲线的模式，通过机械视觉可视化TSFE过程，并为手术策略提供新的视角。材料和方法：纳入的患者需要同时放置种植体和TSFE。进行术前计划，手术期间，在外科医生的监督下，使用外径钻孔，引导机械臂在窦底制造微骨折，提升窦膜，放置植入物。术后锥形束计算机断层扫描评估鼻窦提升和种植体准确性。视觉模拟量表用于测量患者报告的结果。利用提取的力反馈值绘制力学曲线。结果：共纳入17例患者（18个种植体），术后6个月种植体保留率为94.4%。Fz力反馈曲线呈现出一个临界峰值，在窦底突破点处急剧下降，随着移骨进入窦腔，Fz力反馈曲线逐渐上升后急剧下降。结论：基于力反馈的种植体机器人技术结合OD是一种创新可靠的TSFE治疗方法。将机械视觉与力反馈曲线相结合，可以精确识别微骨折点和安全的窦膜抬高，克服了传统盲技术的局限性，提高了手术的安全性和可预测性。试验注册：中国临床试验注册中心：ChiCTR2300072248。
