Reproducible Major Mold for a Silicone Orbital Prosthesis Prototype

Abstract

The implant-supported magnet-retained silicon orbital prosthesis (SOP) was reported as a reliable method to restore the health-related quality of life of patients who underwent facial resection and reconstruction surgery. Currently, fabrication usually requires a long production time and a high level of expertise. Moreover, due to the complex features of facial defects, accurate prosthesis requires many patient fittings.The prosthesis was designed to repair a complex orbital defect. A reproducible major mold was used to make various silicone prototypes with differences in margin design, silicone shade, and artificial eye's details. The most suitable silicone prototype was chosen for the finalization of the SOP. The patient reported the satisfaction with the function, prosthesis retention, and esthetic restoration.This clinical study showed that the new technique using a reproducible major mold can allow the fabrication of various prototypes, save time during fitting, and help in improving personalized fabrication of the SOP.
