Abstract

A dental bleaching device may include a flexible backing material, and a dental composition in contact with the flexible backing material. The dental composition may include a thickening agent and a peroxide bleaching agent. The dental composition may be a gelatinous compound having physical deformation properties that allow the dental composition to bend and conform to a shape of a container into which the dental composition is placed, but the dental composition will not merge into a second piece of the dental composition when placed in contact with the second piece. The dental composition will not crack or break when the dental bleaching device is flexed.

First claim

What is claimed is:

1. A dental bleaching device, comprising:
a dental bleaching device comprising a dental composition on a strip of backing material, wherein the strip of backing material is flexible and insoluble in water;
wherein the dental bleaching device is packaged in a package;
wherein the dental composition, when applied on the strip of backing material, comprises a peroxide bleaching agent, a first solvent, and a thickening agent;
wherein the first solvent is water;
wherein the thickening agent is at least one of poly(2-ethyl-2-oxazoline) and polyvinylpyrrolidone;
wherein, when the dental composition is applied on the strip of the backing material, the thickening agent is included in an amount more by weight of the dental composition than the water;

wherein the dental composition is dried after being applied on the strip of backing material;
wherein the dental composition is gelatinous and visco-elastic
(a) after the dental composition has been applied on the backing material and dried,
(b) during storage of the dental bleaching device at room temperature for a period of time up to six months in the package,
(c) after the dental bleaching device has been removed from the package, and
(d) when the dental composition is flexibly positioned on teeth; and

wherein the dental composition has physical deformation properties such that, after the dental bleaching device has been removed from the package, the dental composition may be positioned on surfaces of adjacent teeth in a dental arch, bend and conform to surfaces of adjacent teeth in a dental arch, and remain on the strip of backing material during use.

2. The dental bleaching device of claim 1 ,
wherein the dental composition will deform under its own weight if removed from the backing material after the dental composition has been dried.

3. The dental bleaching device of claim 1 , wherein, when the dental composition is applied on the strip of the backing material, the dental composition has a viscosity in the range of 1,000 to 200,000 centipoise.

4. The dental bleaching device of claim 1 ,
wherein, when the dental composition is applied on the strip of backing material, the dental composition further comprises a second solvent; and
wherein the second solvent is an organic solvent that is at least one of ethanol, polyethylene glycol, polypropylene glycol, glycerin, and propylene glycol.

5. The dental bleaching device of claim 1 ,
wherein, when the dental composition is applied on the strip of backing material, the dental composition further comprises a second solvent;
wherein the second solvent is an organic solvent; and
wherein, when the dental composition is applied on the strip of the backing material, more water is included in the dental composition by weight than the organic solvent.

6. The dental bleaching device of claim 5 , wherein the organic solvent is at least one of ethanol, polyethylene glycol, polypropylene glycol, glycerin, and propylene glycol.

7. The dental bleaching device of claim 5 , wherein, when the dental composition is applied on the strip of the backing material, the thickening agent is included in the dental composition in an amount less than the combined weight ofthe water and the organic solvent.

8. The dental bleaching device of claim 5 , wherein, when the dental composition is applied on the strip of the backing material, the thickening agent is included in the dental composition in an amount more by weight of the dental composition than the combined weight of the water and the organic solvent.

9. The dental bleaching device of claim 1 , wherein the thickening agent is polyvinylpyrrolidone.

10. The dental bleaching device of claim 1 , wherein the thickening agent is poly(2-ethyl-2-oxazoline).

11. The dental bleaching device of claim 1 , wherein, when the dental composition is applied on the strip of the backing material, the thickening agent is included in the dental composition in an amount between about 33% to about 50% by weight of the dental composition.

12. The dental bleaching device of claim 1 , wherein, when the dental composition is applied on the strip of the backing material, the peroxide bleaching agent is included in the dental composition in an amount within a range of about 11% to about 27% by weight of the composition.

13. The dental bleaching device of claim 1 , wherein, when the dental composition is applied on the strip of the backing material, the peroxide bleaching agent is included in the dental composition in an amount up to about 50% by weight of the composition.

14. A dental bleaching device, comprising:
a dental bleaching device comprising a dental composition on a strip of backing material, wherein the strip of backing material is flexible and insoluble in water;
wherein the dental bleaching device is packaged in a package;
wherein the dental composition, when applied on the strip of backing material, comprises a peroxide bleaching agent, a first solvent, a second solvent, and a thickening agent;
wherein the first solvent is water and the second solvent is an organic solvent;
wherein the thickening agent is at least one of poly(2-ethyl-2-oxazoline) and polyvinylpyrrolidone;
wherein, when the dental composition is applied on the strip of the backing material, the thickening agent is included in an amount more by weight of the dental composition than the water, more by weight of the dental composition than the organic solvent, and more by weight of the dental composition than the peroxide bleaching agent;

wherein the dental composition is dried after being applied on the strip of backing material;
wherein the dental composition is gelatinous and visco-elastic
(a) after the dental composition has been applied on the strip of backing material and dried,
(b) during storage of the dental bleaching device at room temperature for a period of time up to six months in the package,
(c) after the dental bleaching device has been removed from the package, and
(d) when the dental composition is flexibly positioned on teeth; and

wherein the dental composition has physical deformation properties such that, after the dental bleaching device has been removed from the package, the dental composition may be positioned on surfaces of adjacent teeth in a dental arch, bend and conform to surfaces of adjacent teeth in a dental arch, and remain on the strip of backing material during use.

15. The dental bleaching device of claim 14 , wherein the dental composition will deform under its own weight if removed from the backing material after the dental composition has been dried.

16. The dental bleaching device of claim 14 , wherein, when the dental composition is applied on the strip of the backing material, the dental composition has a viscosity in the range of 1,000 to 200,000 centipoise.

17. The dental bleaching device of claim 14 , wherein the organic solvent is ethanol.

18. The dental bleaching device of claim 14 , wherein the organic solvent is at least one of ethanol, polyethylene glycol, polypropylene glycol, glycerin, and propylene glycol.

19. The dental bleaching device of claim 14 , wherein, when the dental composition is applied on the strip of the backing material, more water is included in the dental composition by weight than the organic solvent.

20. The dental bleaching device of claim 19 , wherein the organic solvent is at least one of ethanol, polyethylene glycol, polypropylene glycol, glycerin, and propylene glycol.
