Abstract
Dental light-curing resins are cured with light and under pressure by placing the uncured resin on a cast or mold or dental appliance to be prepared then covered with a transparent or translucent flexible membrane or sheet. In a chamber gas pressure is applied to the sheet and, in turn, to all parts of the underlying resin and, while pressurized, the resin is exposed to light to cure it.
