A mold technique for orbital prostheses

Area of Science:

• Maxillofacial prosthodontics
• Dental materials science

Background:

• Maxillofacial prostheses are crucial for restoring function and appearance after surgery or trauma.
• Achieving accurate esthetic characterization and a precise fit can be challenging, particularly with complex facial contours and tissue undercuts.

Purpose of the Study:

• To introduce an innovative technique for fabricating maxillofacial prostheses that accommodates tissue undercuts.
• To enable trial closure for enhanced esthetic evaluation during the prosthesis fabrication process.
• To simplify the final trimming and fitting of the prosthesis.

Main Methods:

• The described technique involves a specific method for incorporating tissue undercuts into the prosthesis design.
• A key procedural step includes placing the finish line on the external eyelid.
• This allows for iterative trial closure and adjustment for esthetic refinement.

Main Results:

• The technique successfully allows for trial closure, facilitating detailed esthetic characterization.
• Strategic placement of the finish line on the external eyelid simplifies the final trimming procedure.
• This method enhances the precision and efficiency of maxillofacial prosthesis fabrication.

Conclusions:

• The presented technique offers a viable solution for fabricating maxillofacial prostheses with challenging undercuts.
• It improves the esthetic outcome through facilitated trial closure and characterization.
• The method streamlines the fabrication process, particularly the final trimming stage.
