Clinical Report: Robotic Osteotomy May Better Match Root Geometry
Overview
An autonomous robotic osteotomy system demonstrates superior accuracy in reproducing planned recipient socket geometry for tooth autotransplantation compared to static guide-assisted preparation, particularly in double-rooted models.
Background
Tooth autotransplantation is a viable treatment option for tooth agenesis, and achieving precise socket preparation is critical for successful outcomes. The advent of robotic systems in dental surgery offers potential improvements in accuracy and efficiency.
Data Highlights
| Outcome | Robotic Preparation | Static Guide Preparation |
|---|---|---|
| Apex Deviation (mm) | 0.94 | 1.96 |
| Angular Deviation (°) | 1.86 | 7.32 |
| Root-Mean-Square Surface Deviation (mm) | 0.20 | 0.33 |
| Dice Similarity Coefficient (%) | 88 | 63 |
| Over-Removal Rate (%) | 8 | 96 |
| Preparation Time (seconds) | 759 | 833 |
Key Findings
- Robotic preparation achieved a mean apex deviation of 0.94 mm compared to 1.96 mm for static guide preparation.
- In double-rooted models, apex deviation was significantly lower with robotic techniques (0.85 mm vs 2.38 mm).
- Angular deviation favored robotic preparation at 1.86° overall compared to 7.32° with static guidance.
- Robotic preparation resulted in a lower over-removal rate (8%) compared to static guidance (96%).
- Preparation times were similar between techniques, but varied by root anatomy.
Clinical Implications
The findings indicate that robotic osteotomy may enhance the precision of socket preparation in tooth autotransplantation.
Conclusion
The study indicates that robotic osteotomy can significantly improve the accuracy of socket preparation for tooth autotransplantation.
