Abstract
An ocular prosthesis for use directly or as a component for an orbital prosthetic appliance to replace the eye piece consisting essentially of urethane dimethacrylate. Use of this acrylic resin polymerized with a visible light cure offers a clinically acceptable, clean and expedient way to construct this appliance. The method of construction is less time consuming compared to existing methods and utilizes a polymer with essentially no fugitive monomer or solvent. The prosthesis is a compatible alternative for patients experiencing methylmethacrylate sensitivity.
Claims8
