Silicone cure inhibition with material jetting additive manufacturing utilized for facial prosthesis fabrication – A clinical report

This clinical report outlines the prosthetic restoration of a 92-year-old Caucasian patient who underwent a partial rhinectomy. Utilizing CAD-CAM technology, scanning and design were accomplished digitally, and material jetting additive manufacturing was used to create a two-piece mold for a partial nasal silicone prosthesis. An unprecedented challenge was observed involving cure inhibition when the silicone came into contact with the additively manufactured (AM) material, and multiple attempted strategies to remedy this situation were discussed. The report emphasizes the critical need for further research to optimize digital workflows in prosthetic facial rehabilitation.
