摘要

目的：评估和比较机器人辅助导航系统和动态导航系统在单牙缺失或多牙连续缺失的远端延伸模型中的种植体放置的准确性。方法：采用32个模型和86个植入物。植入物放置随机分配使用机器人辅助或动态导航系统。通过叠加计划和实际种植体位置来评估准确性。主要研究结果是角度偏差，而次要结果包括种植体入口和尖端水平的三维偏差。结果：在所有模型中，机器人辅助组的中位角偏差为1.15°，而动态导航组的中位角偏差为1.99°（P< 0.01）。入口和尖端偏差分别为0.90 mm和1.00 mm，分别为0.92 mm和0.99 mm。单牙组牙根、牙根深度偏差差异有统计学意义（P = 0.038,P = 0.032）。在多牙缺失模型中，机器人辅助系统显示的牙尖、牙尖和牙尖水平偏差明显低于动态导航系统（P< 0.05）。结论：两种方法在体外放置种植体时均具有较高的准确性。然而，机器人辅助的方法可以提供更高的精度，特别是在涉及多颗牙齿缺失的复杂病例中。临床意义：本研究中机器人辅助方法在准确性方面的偏差较小，为机器人在相对复杂的植入手术中的应用提供了潜在的好处。

Evaluation of the accuracy of dynamic navigation versus robot-assisted dental implant placement in models with one missing tooth or multiple missing teeth with a free-end: an in vitro study

Objectives

To assess and compare the accuracy of robot-assisted and dynamic navigation systems for dental implant placement in models with either a single missing tooth or multiple consecutive missing teeth at the distal extension.

Methods

Thirty-two models and 86 implants were utilized. Implant placement was randomly assigned using either a robot-assisted or dynamic navigation system. The accuracy was evaluated by superimposing planned and actual implant positions. The primary study outcome was angular deviation, while secondary outcomes included three-dimensional deviations at the implant entry and apex levels.

Results

Across all models, the robot-assisted group demonstrated a median angular deviation of 1.15°, compared to 1.99° with the dynamic navigation system (P < 0.01). Entry and apex deviations were 0.90 mm vs. 0.92 mm and 1.00 mm vs. 0.99 mm, respectively. In single-tooth cases, significant differences between groups were observed in entry and apex depth deviations (P = 0.038 and P = 0.032, respectively). In models with multiple missing teeth, the robot-assisted system showed significantly lower angular, apex, and apex horizontal deviations than dynamic navigation system (P < 0.05).

Conclusion

Both approaches yield a high degree of accuracy in vitro for implant placement. However, the robot-assisted approach may offer improved precision, particularly in complex cases involving multiple missing teeth.

Clinical significance

The lower deviations in terms of accuracy demonstrated by the robot-assisted approach in the study would have potential benefits for the application of robots in relatively complex implant surgeries.

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
