ABSTRACT:
A curing apparatus providing rapid curing by using light, pressure, pressure and light, or purge, pressure and light to cure resinous materials by application of energy from an external source to excite polymerization in a polymerizable system. A curing chamber is provided to house the polymerizable dental material. The apparatus utilizes light emitting diodes (LEDs) to radiate energy to polymerize the dental materials. The LEDs are positioned optimally within the curing apparatus to provide efficient, effective polymerization of the dental materials.
