Eclipse Prosthetic Resin System is a revolutionary new method for making dentures. With Eclipse, denture fabrication is extremely simplified, since the lost wax technique is no longer required and there is no need for investing, flasking and boiling-out. Instead of using wax, dentures are directly built-up with three layers of Eclipse resin (Base Plate, Set-up and Contour Resin). After a successful try-in, dentures are directly processed. All three Eclipse resins are MMA-free and handle like wax. The cured resins show outstanding aesthetics and exhibit good mechanical properties.
