Virtual Dental Sculpting Simulator
Haptic-based dental procedure training
A surface-based virtual dental sculpting simulator combining auditory, visual, and tactile feedback. It supports grinding, drilling, and surface scrubbing with multiple virtual dental tools — useful preparation before real-patient procedures.
System components
- Model reduction
- Mesh refinement
- Collision detection
- Local subdivision of triangles
- Local model updating
- Force feedback
- Visual and audio rendering
Why? During dental procedures, practitioners must learn to operate instruments precisely and develop a realistic sense of touch for the interaction with patient anatomy. A virtual simulator provides repetitive, safe practice before live procedures.
Features
- Model reduction for higher update rates
- Multiple triangular subdivision algorithms (Loop, Sqrt(3), Butterfly, 9-split, 4-split, 3-split, Bi-tri)
- Various dental tools: spherical excavator, spherical drilling cutter, cylindrical cutter, cone cutter
- Surface-based tool modelling with good visual quality
- OBB-based collision detection
- Local triangle subdivision
- Enhanced force-filtering algorithm for tactile feedback
- Realistic cutting sound
- Material removal on any scanned model from a commercial 3D dental scanner
Video
This video presents the simulator with mixed auditory, visual, and tactile feedback. Phantom Omni is used as the haptic device, offering three degree-of-freedom force output and six degree-of-freedom position sensing.
