Reproducible Major Mold for a Silicone Orbital Prosthesis Prototype.

Area of Science:

• Ophthalmology
• Prosthodontics
• Biomaterials

Background:

• Facial resection and reconstruction surgery often result in complex orbital defects.
• Current fabrication of silicon orbital prostheses (SOPs) is time-consuming, requires high expertise, and involves numerous patient fittings.
• Restoring quality of life for patients with orbital defects is crucial.

Purpose of the Study:

• To present a novel technique for fabricating implant-supported magnet-retained silicon orbital prostheses (SOPs).
• To reduce the production time and complexity associated with SOP fabrication.
• To improve the personalized fit and esthetic outcome of SOPs for patients with orbital defects.

Main Methods:

• Development of a reproducible major mold for creating multiple silicone prototypes.
• Variations in margin design, silicone shade, and artificial eye details were explored across prototypes.
• Selection of the optimal silicone prototype for final SOP fabrication.

Main Results:

• The new technique using a reproducible major mold facilitated the fabrication of diverse prototypes.
• This approach significantly reduced fitting time for patients.
• The final SOP demonstrated patient satisfaction regarding function, retention, and esthetics.

Conclusions:

• A reproducible major mold technique offers an efficient method for personalized SOP fabrication.
• This innovative approach enhances the fabrication process for implant-supported magnet-retained silicon orbital prostheses.
• The technique improves patient outcomes and satisfaction in restoring orbital defects.
