Generation of three-dimensional prototype models based on cone beam computed tomography.

Area of Science:

• Biomedical Engineering
• Dental Education
• Medical Imaging

Background:

• Three-dimensional (3D) models offer valuable visualization tools for anatomical education.
• Digital volumetric data, such as from cone beam computed tomography (CBCT), provides a basis for creating patient-specific anatomical models.

Purpose of the Study:

• To generate 3D models from digital volumetric data for application in basic and advanced educational settings.
• To explore the feasibility of fabricating anatomical models using CBCT datasets.

Main Methods:

• Acquired four sets of digital volumetric data using cone beam computed tomography (CBCT).
• Processed DICOM datasets using Mimics and Magic software to segment anatomical structures (nerve, tooth, bone).
• Fabricated 3D models using a Polyjet 3D Printing machine.

Main Results:

• Successfully fabricated 3D prototype models of specific anatomical structures.
• Demonstrated the volumetric acquisition and fabrication of detailed anatomical models.

Conclusions:

• Generating 3D models from CBCT datasets is technically achievable.
• Current automated fabrication processes are time-consuming and expensive for routine use.
• Further optimization is needed to make 3D model fabrication cost-effective for educational purposes.
