Abstract
A dental bleaching device may include a backing material made of a polymeric wax mixture, and a dental composition in contact with the 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.
Claims35
A dental bleaching device, comprising:
- a strip of backing material, wherein the strip of backing material is flexible and planar such that the strip of backing material has two flat sides;
- a dental composition on one of the flat sides of the strip of backing material such that at least substantially all of one side of the backing material is covered solely by the dental composition;
- 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 comprises is at least one of poly(2-ethyl-2-oxazoline) and polyvinylpyrrolidone;
- 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 a package,
- (c) after the dental bleaching device has been removed from a package, and
- (d) when the dental composition is flexibly positioned on teeth;
- wherein the dental composition has physical deformation properties such that, after the dental bleaching device has been removed from a 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;
- and
- wherein the dental composition has adhesive properties such that, after the dental bleaching device has been removed from a package and is then positioned on adjacent teeth in a dental arch, the dental composition will adhere to surfaces of adjacent teeth in a dental arch.
