This study demonstrates realistic virtual simulation of dental surgical procedures, like apicectomies, using a novel 3D system. The simulation provides haptic feedback and visual accuracy for complex anatomical models.

Area of Science:

  • Computer-assisted surgery
  • Virtual reality in medicine
  • Dental simulation

Context:

  • Selective bone reduction is crucial in dental surgery, requiring precision to avoid damaging vital structures.
  • Existing surgical techniques necessitate advanced simulation tools for training and planning complex procedures.
  • Virtual drilling offers a new approach to practicing bone reduction without patient risk.

Purpose:

  • To develop and evaluate a virtual reality system for simulating dental surgical procedures, specifically apicectomies.
  • To create a realistic simulation environment using the VOXEL-MAN system with high-resolution 3D models.
  • To integrate haptic feedback and auditory cues for an immersive surgical simulation experience.

Summary:

  • A virtual 3D skull model was created from CT data using the VOXEL-MAN system, incorporating inferior alveolar nerves and simulated apical inflammations.

  • Special tools and force feedback were integrated for realistic virtual drilling effects, enhanced by drilling noises and shutter glasses for 3D perception.
  • The simulation allowed for visual and haptic interaction with complex models, with convincing haptic feedback and enabling postoperative verification of drilling routes.

    • Impact:

    • This technology enables realistic simulation of complex dental surgical procedures, including apicectomies, on virtual anatomical models.
    • The system can be extended to include virtual pathologies and utilize anonymized patient data for broader surgical training applications.
    • Virtual simulation enhances surgical planning, training, and potentially reduces risks associated with complex dental interventions.
