[3D solid model of mandible with dental arch via LOM method]

Area of Science:

• Biomedical Engineering
• Dental Technology
• 3D Imaging

Context:

• Accurate anatomical models are crucial for dental education and prosthetics.
• Traditional methods for creating dental models can be time-consuming and less precise.
• Advancements in 3D scanning and rapid prototyping offer new possibilities for dental applications.

Purpose:

• To create a highly accurate, solid 3D model of the mandible with a dental arch using CT scan data.
• To evaluate the feasibility and accuracy of using LOM (Laminated Object Manufacturing) rapid prototyping for dental models.
• To assess the model's suitability for prosthetic dentistry education and computer-aided design (CAD).

Summary:

• 3D reconstruction data from CT scans was processed into an STL file.
• The data was refined using Magics RP software for accurate geometric reproduction.
• A rapid prototype (RP) model of the mandible with a dental arch was successfully generated using LOM technology.

Impact:

• The generated RP model demonstrates high geometric similarity to the original anatomy.
• The model's accuracy meets the requirements for prosthetic dentistry students.
• This technique opens avenues for computer-aided design in prosthetic dentistry based on 3D solid models.
