Summary
This study quantifies tooth extraction movements using a robotic arm. Rotation around the tooth
Area of Science:
- Biomechanical Engineering
- Dental Surgery
- Robotics
Background:
- Tooth extraction is a common invasive procedure with limited scientific advancement in understanding its mechanics.
- Technical challenges in measuring keyhole surgical movements hinder progress.
Purpose of the Study:
- To precisely measure the complete range of motion and angular velocities during tooth extraction.
- To quantify movement parameters in clinically relevant directions.
Main Methods:
- Developed an ex vivo measurement setup utilizing a compliant robot arm.
- Employed fresh-frozen cadavers and standard dental forceps to simulate clinical conditions.
- Collected data from 110 successful tooth extraction experiments.
Main Results:
- Rotation around the tooth's longitudinal axis demonstrated the largest range of motion and angular velocity.
- Buccopalatal and buccolingual movements were more significant in the posterior regions of both jaws.
- Established quantitative data for motion ranges and angular velocities in tooth extraction.
Conclusions:
- This research provides a quantitative understanding of tooth extraction biomechanics.
- Findings can inform the development of evidence-based training materials for dental professionals.
- Highlights the need for advanced measurement techniques in surgical procedures.
