In-House 3D Printing and Model Processing Technique for Creating High-Fidelity Transparent Craniofacial Models

Area of Science:

• Medical Engineering
• Surgical Planning
• 3D Printing in Medicine

Background:

• High-fidelity stereolithographic models are vital in craniofacial surgery.
• Existing 3D models often lack detail of intraosseous structures, limiting surgical planning.
• Limited resources hinder access to advanced 3D modeling for many medical centers.

Purpose of the Study:

• To develop a novel, cost-effective technique for creating transparent 3D craniofacial models.
• To improve preoperative planning and intraoperative guidance for craniofacial osteotomies.
• To highlight critical intraosseous anatomy, including nerves and tooth roots.

Main Methods:

• Utilized a novel technique for producing transparent 3D models.
• Focused on accurately representing patient-specific intraosseous craniofacial anatomy.
• Demonstrated applications in planning osteotomies requiring visualization of critical structures.

Main Results:

• Successfully created high-fidelity transparent 3D models at a reduced cost.
• Accurately displayed tooth roots, inferior alveolar nerve, and optic nerve.
• Showcased diverse applications for preoperative planning.

Conclusions:

• The novel technique offers a low-cost solution for producing transparent 3D models.
• These models enhance the visualization of critical intraosseous structures for craniofacial surgery.
• This advancement aids in preoperative planning and reduces the risk of intraoperative injury.
