Summary
Three-dimensional (3D) haptic patient models created from cone-beam computed tomography (CBCT) data enhance dental education. These realistic models allow students to practice surgical procedures safely before real-world application.
Area of Science:
- Dental Education
- Medical Imaging
- Additive Manufacturing
Background:
- Cone-beam computed tomography (CBCT) is crucial for dental diagnostics.
- Traditional dental education relies on theoretical knowledge and limited practical simulation.
- Need for advanced training tools in oral surgery education.
Purpose of the Study:
- To develop and evaluate three-dimensional (3D) haptic patient models using CBCT data for dental education.
- To assess the utility of these models in simulating oral surgical procedures for undergraduate and postgraduate dental trainees.
Main Methods:
- Acquisition of CBCT patient data sets.
- Processing data using DICOM and MIMICS software for tissue differentiation (bone, teeth, nerve).
- Fabrication of 3D haptic models via additive manufacturing and integration into phantom heads.
Main Results:
- Successful creation of 3D haptic models representing patient-specific anatomy.
- Models accurately differentiated bone, teeth, and nerve tissues.
- Models were integrated into standard dental phantom heads for educational use.
Conclusions:
- CBCT-based 3D haptic models are valuable tools for undergraduate and postgraduate dental education.
- These models facilitate supervised simulation of routine and complex oral surgical procedures.
- Enhanced surgical preparedness and skill development for dental trainees.
