Abstract

A 3-dimensional curing light that can cure a light curable material, such as a dental restoration, from 3 directions at once.

First claim

What is claimed is:

1. A single tooth curing light head for simultaneously emitting polymerizing light energy upon a crown and first and second exposed sides of a single tooth, comprising:
a housing sized and configured to cover only a single tooth at a time;
a first facet positioned within the housing, said first facet configured for facing the crown of the single tooth when the housing is placed over the single tooth;
a second facet positioned within the housing, said second facet configured for facing the first exposed side of the single tooth when the housing is placed over the single tooth; and
a third facet positioned within the housing, said third facet configured for facing the second exposed side of the single tooth when the housing is placed over the single tooth;
wherein each of said first, second, and third facets, includes an outer surface and an inner surface spaced from said outer surface; wherein an LED is mounted therein each of said first, second, and third facets, within a space defined by said outer surface spaced from said inner surface; each said LED is positioned to emit light energy upon respective ones of the crown and first and second exposed sides of the single tooth; and
wherein each LED is mounted on a heat sink, which is spaced from the respective outer surface of the first, second, and third facets, forming a heat insulation layer defined by an air gap between each said heat sink and the respective outer surface of the first, second, and third facets.

2. The curing light head of claim 1 , wherein a heat conduction paste is located between each said LED and each said heat sink.

3. The curing light head of claim 1 , wherein said second and third facets are oriented parallel to one another.

4. The curing light head of claim 1 , wherein said first facet is oriented at about ninety degree angle with respect to at least one of the second and third facets.

5. A single tooth curing light head for emitting polymerizing light energy upon a crown and first and second exposed sides of a single tooth, comprising:
a first facet, said first facet configured to be positioned to face the crown of the single tooth;
a second facet, said second facet configured to be positioned to face the first exposed side of the single tooth; and
a third facet, said third facet configured to be positioned to face the second exposed side of the single tooth;
said first, second, and third facets combining to cover only a single tooth at one time; and
wherein each of said first, second, and third facets, having an LED attached thereto and positioned to emit light energy upon respective ones of the crown and first and second exposed sides of the single tooth; wherein each said LED is positioned within a space defined by a corresponding outer surface and inner surface spaced from said outer surface of each of said first, second, and third facets; and
wherein each said LED is mounted on a heat sink, which is spaced from the respective outer surface of the first, second, and third facets, forming a heat insulation layer defined by an air gap between each said heat sink and the respective outer surface of the first, second, and third facets.

6. The curing light head of claim 5 , wherein said second and third facets are oriented parallel to one another.

7. The curing light head of claim 5 , wherein said first facet is oriented at about ninety degree angle with respect to at least one of the second and third facets.

8. The curing light head of claim 5 , wherein a heat conduction paste is located between each said LED and each said heat sink.

9. A curing light for emitting light energy upon surfaces of a single tooth, comprising:
a first facet configured for being positioned proximate a first surface portion of the single tooth;
a second facet configured for being positioned proximate a second surface portion of the single tooth; and
a third facet configured for being positioned proximate a third surface portion of the single tooth; wherein
said first, second, and third facets combining to cover only a single tooth at a time;
wherein each of said first, second, and third facets, having an LED mounted thereon and positioned to emit light energy upon respective ones of said portions of the tooth, and wherein each said LED is mounted on a heat sink, which is spaced from a corresponding respective outer surface of the first, second, and third facets, forming a heat insulation layer defined by an air gap between each said heat sink and the corresponding respective outer surface of the first, second, and third facets; and
a control box electrically connected to the LEDs that controls the operation of the LEDs, capable of controlling power, curing mode, and light emitting selections.

10. The curing light of claim 9 , wherein said second and third facets are oriented parallel to one another.

11. The curing light of claim 9 , wherein said first facet is oriented at about ninety degree angle with respect to at least one of the second and third facets.
