Area of Science:

Biomedical Engineering
Dental Education Technology

Background:

Traditional dental training relies on physical models and cadavers, which can be costly and limited in scope.
Developing advanced simulation tools is crucial for enhancing the efficiency and effectiveness of dental education.

Purpose of the Study:

To introduce a novel virtual reality (VR) dental training system with haptic feedback.
To develop an intelligent module for monitoring, classifying, and training dental students.
To enable proactive skill acquisition through expert procedure replication.

Main Methods:

A VR simulator was developed, featuring graphical and haptic simulation of tooth preparation.
Hidden Markov Models (HMMs) were employed for objective performance assessment using simulator-collected data.

An intelligent training module was implemented for recording, replaying, and guiding procedural steps.

Main Results:

Dentists found the graphics and haptic fidelity of the simulator to be acceptable.
The HMM-based performance assessment demonstrated 100% accuracy in classifying user skill levels.
The system successfully simulated realistic tooth surface exploration and cutting procedures.

Conclusions:

The VR dental simulator offers a realistic training environment with accurate performance assessment.
The intelligent training module enables proactive skill transfer, surpassing traditional passive methods.
Further research with larger participant groups and diverse training strategies is planned.
