First in-human intervention using a semi-automated robot for tooth restorative treatment

Area of Science:

• Dentistry
• Robotics
• Digital Health

Background:

• Digital technologies have revolutionized dentistry, improving precision and efficiency.
• Robotic systems offer automated workflows, minimizing human error in dental treatments.
• Traditional crown preparation is a multi-step process requiring multiple patient visits.

Purpose of the Study:

• To evaluate the first in-human application of a semi-automated robotic tooth preparation system (SARP).
• To assess the precision, efficiency, and patient experience of SARP in restorative dentistry.

Main Methods:

• A semi-automated robotic tooth preparation system (SARP) was used for digital preplanning and execution of tooth preparation.
• The system achieved sub-50µm precision in tooth preparation.
• Restorations were pre-manufactured for same-day delivery and cementation.

Main Results:

• The root mean square deviation of tooth preparation was 39µm, demonstrating high precision.
• Prepared crowns (n=5) exhibited good-to-excellent fit and were cemented in the same visit.
• No adverse events or pain were reported by the six participating patients.

Conclusions:

• SARP enhances procedural precision, reduces treatment times, and improves patient satisfaction in restorative dentistry.
• The system offers increased practice efficiencies and potential for same-day dental restorations.
• Future integration with advanced imaging and larger trials are planned to validate outcomes and cost-effectiveness.
