Background:

Traditional orbital prosthesis fabrication uses the "lost wax" technique.
Existing molds are prone to fracture and dissolution due to small constituent parts.
This limits the durability and repeatability of prosthesis production.

Purpose of the Study:

To develop a more robust and resilient mold for orbital prostheses.
To overcome the limitations of traditional mold materials and fabrication methods.
To improve the precision and longevity of ocular prosthesis manufacturing.

Main Methods:

A novel mold design incorporating light-polymerized resin was developed.
The resin surrounds the palpebral part of the orbital mold.

Related Experiment Videos

This method aims to enhance the structural integrity of the mold.

Main Results:

The novel mold exhibits increased resistance to fracture compared to traditional methods.
The light-polymerized resin provides enhanced durability against repeated pressing.
The improved mold design maintains the fidelity of the palpebral fissure details.

Conclusions:

The developed light-polymerized resin mold offers a significant improvement in durability for orbital prostheses.
This technique addresses the shortcomings of conventional "lost wax" methods.
The enhanced mold is suitable for precise and repeated fabrication of ocular prosthetics.
