Abstract: A curing apparatus wherein rapid curing is provided 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. An air-tight chamber is provided to house the polymerizable dental material. The apparatus provides an automated system for curing the polymerizable material under light and pressure in the same unit. A purge cycle may be included to minimize or eliminate bubbles and provide an oxygen-free atmosphere.

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.

Abstract: A calibration device for a dental furnace includes a meltable element located on a hollow tube. The melting of the meltable element breaks the seal and reduces the vacuum pressure in the furnace thereby triggering the controller to calibrate the temperature of the furnace to the melting temperature of the meltable element. Alternatively, a calibration device comprises a solid tube having a groove thereon is positioned in the furnace and a metal strip is positioned on the solid tube. Upon melting of the metal strip, the solid tube is displaced and the seal is broken allowing air from the external environment to access the furnace atmosphere. The change in vacuum pressure is detected and the temperature in the furnace and the melting point of the metal strip is used as the reference temperature to calibrate the furnace.

Abstract: A curing/whitening unit provides a light guide and a conduit for delivering a source of cooling fluid to or near the surface being cured as radiant energy of a light beam is directed on the material to be cured. An outlet for the cooling fluid is provided integral the curing unit proximate the outlet or tip of the light guide of the curing unit to provide simultaneous cooling fluid to the mouth as curing or whitening is occurring.
