Abstract
An apparatus and method for curing light curable material using unfiltered light. A vented housing encloses a single lamp filament light source which emits visible light. The light source is positioned above and to the side of the light curable material which is supported on a rotating table during light curing. Light incident to the surface of the light curable material is at least about 50 milliwatts per square centimeter. The light curable material has a surface temperature of at least 150.degree. F. (65.6.degree. C.) after 2 minutes.
Claims17
An apparatus for polymerization of light curable material, comprising:
- a housing, and
- an incandescent lamp, having a filament and a gas,
- said lamp being supported and enclosed by said housing, said filament being enclosed by said gas, said gas comprising halogen gas, said filament providing sufficient electromagnetic radiation to maintain the temperature of said light curable material within said housing at between about 120.degree. F. and about 250.degree. F. and to substantially evenly cure said light curable material while rotating said light curable material.
A system for polymerization of light curable material, comprising:
- light curable material,
- a housing, and
- an incandescent lamp having a filament and a gas, said lamp being supported and enclosed by said housing, said filament being enclosed by said gas, said gas comprising halogen gas, said light curable material being enclosed by said housing, said filament providing sufficient electromagnetic radiation to maintain the temperature of said light curable material between about 120.degree. F. and about 250.degree. F. and said light curable material being substantially evenly cured by said radiation from said filament while rotating said light curable material within said housing.
A method of making a denture, comprising:
- providing an apparatus for polymerization of light curable material, said apparatus having a housing, and
- an incandescent lamp having a filament and a gas,
- said lamp being supported and enclosed by said housing, said gas comprising a halogen, said filament providing sufficient electromagnetic radiation to maintain the temperature of said light curable material within said housing at between about 120.degree. F. and about 250.degree. F. and to substantially evenly cure said light curable material while rotating said light curable material.
