An autonomous robot demonstrated superior angular accuracy for dental implant placement compared to dynamic navigation. While robotic surgery showed better precision in angle, linear deviations and clinical outcomes were similar between the two methods.
Area of Science:
- Dental Implantology
- Robotic Surgery
- Surgical Navigation Technologies
Background:
- Dental implant placement accuracy is crucial for successful outcomes.
- Advancements in surgical navigation aim to improve precision and predictability.
- Autonomous robotic systems offer potential for enhanced control in dental procedures.
Purpose of the Study:
- To compare the accuracy and clinical outcomes of autonomous robot (AR) versus dynamic navigation (DN) for dental implant placement.
- To evaluate angular and linear deviations, surgical time, and patient-reported outcomes.
- To assess the early success rate of implants placed using AR and DN systems.
Main Methods:
- A prospective, open-label, randomized controlled trial involving 40 patients with a single missing tooth.
- Patients were randomized into two groups: autonomous robot (n=20) and dynamic navigation (n=20).
- Both systems utilized identical optical tracking technology for implant placement analysis.
Main Results:
- The autonomous robot group showed significantly lower angular deviation (1.01° ± 0.65°) compared to dynamic navigation (1.78° ± 1.15°, p < 0.01).
- No significant differences were observed in coronal and apical linear deviations between the groups.
- Surgical time was longer in the AR group (21.52 min vs. 14.27 min, p < 0.01), but postoperative pain, edema, complications, and early implant success rates were comparable.
Conclusions:
- Autonomous robotic systems offer superior angular accuracy in dental implant placement compared to dynamic navigation.
- Linear deviations and overall early clinical outcomes were not significantly different between the two navigation methods.
- Further research may explore optimizing robotic system efficiency and patient benefits.
