Abstract

An oral treatment device that emits light onto surfaces of a user's teeth. In one aspect, the oral treatment device includes an intraoral mouthpiece. The mouthpiece comprises: a first light emitting surface configured to emit light onto a user's maxillary teeth, the first light emitting surface having a concave curvature; a second light emitting surface configured to emit light onto a user's mandibular teeth, the second light emitting surface having a concave curvature; the first and second light emitting surface located on opposite sides of a horizontal reference plane; the first light emitting surface inclined so that a first acute angle is formed between with the first light emitting surface and the horizontal reference plane; and the second light emitting surface inclined so that a second acute angle is formed between with the second light emitting surface and the horizontal reference plane.

First claim

What is claimed is:

1. An oral treatment device comprising:
an intraoral mouthpiece comprising:
a first light emitting surface configured to emit light onto a user's maxillary teeth, the first light emitting surface being a smooth exposed surface having a concave curvature;
a second light emitting surface configured to emit light onto a user's mandibular teeth, the second light emitting surface being a smooth exposed surface having a concave curvature;
the first and second light emitting surfaces located on opposite sides of a horizontal reference plane;
the first light emitting surface inclined so that a first acute angle is formed between the first light emitting surface and the horizontal reference plane;
the second light emitting surface inclined so that a second acute angle is formed between the second light emitting surface and the horizontal reference plane; and
a first lamp and a second lamp, the first and second lamps operably coupled to a control circuit having a power source, each of the first and second lamps comprising:
a flexible sheet body having a front surface and a rear surface;
a plurality of light emitters embedded within the flexible sheet body that generate light which is emitted from the rear surface of the flexible sheet body;

a lamp support structure comprising a lamp support surface having a concave curvature, each of the first and second lamps mounted to the lamp support surface so that the rear surface of the flexible sheet body of each of the first and second lamps assumes a concave curvature, thereby forming a lamp assembly; and

wherein the first light emitting surface is inclined at the first acute angle and the second light emitting surface is inclined at the second acute angle when the intraoral mouthpiece is in an unbiased state;
wherein the first and second acute angles are different;
wherein the first light emitting surface is the rear surface of the flexible sheet body of the first lamp and the second light emitting surface is the rear surface of the flexible sheet body of the second lamp; and
wherein the lamp support surface is a stepped surface having a first riser portion, a tread portion, and a second riser portion, the first lamp mounted to and covering the first riser portion and the second lamp mounted to and covering the second riser portion.

2. The oral treatment device according to claim 1 wherein the intraoral mouthpiece further comprises a guard component coupled to the lamp assembly, the guard component comprising: a first frame portion defining a first window through which the rear surface of the flexible sheet body of the first lamp is exposed; and a second frame portion defining a second window through which the rear surface of the flexible sheet body of the second lamp is exposed.

3. The oral treatment device according to claim 1 wherein the intraoral mouthpiece further comprises a bite platform extending from the first and second light emitting surfaces along the horizontal reference plane.

4. The oral treatment device according to claim 1 , wherein each of the first and second lamps comprise a first side edge, a second side edge, an upper edge, and a lower edge; and wherein the lower edge of the first lamp is horizontally offset from the upper edge of the second lamp.

5. The oral treatment device according to claim 1 further comprising: a housing coupled to the intraoral mouthpiece, the housing containing a control circuit that is operably and electrically coupled to each of the first and second lamps; and wherein the first and second lamps are horizontally offset from one another, the first lamp being closer to the housing than the second lamp when measured along the horizontal reference plane.

6. The oral treatment device according to claim 1 wherein each of the first and second acute angles are in a range of 75° to 89°.

7. The oral treatment device according to claim 1 wherein each of the first and second light emitting surfaces is planar in a direction perpendicular to the horizontal reference plane.

8. The oral treatment device according to claim 1
wherein the first and second pluralities of light emitters are located on opposite sides of the horizontal reference plane.

9. The oral treatment device according to claim 8 wherein the first lamp forms a first monolithic component and the second lamp forms a second monolithic component that is separate and distinct from the first lamp, each of the first and second light emitting surfaces extending linearly from the horizontal reference plane at the first and second acute angles.

10. An oral treatment device comprising:
an intraoral mouthpiece comprising:
a first light emitting surface configured to emit light onto a user's maxillary teeth, the first light emitting surface having a concave curvature;
a second light emitting surface configured to emit light onto a user's mandibular teeth, the second light emitting surface having a concave curvature;
the first and second light emitting surfaces located on opposite sides of a horizontal reference plane;
the first light emitting surface inclined so that a first acute angle is formed between the first light emitting surface and the horizontal reference plane;
the second light emitting surface inclined so that a second acute angle is formed between the second light emitting surface and the horizontal reference plane; and
a first lamp and a second lamp, the first and second lamps operably coupled to a control circuit having a power source, each of the first and second lamps comprising:
a flexible sheet body having a front surface and a rear surface; and
a plurality of light emitters embedded within the flexible sheet body that generate light which is emitted from the rear surface of the flexible sheet body;

the first light emitting surface being the rear surface of the flexible sheet body of the first lamp; and
the second light emitting surface being the rear surface of the flexible sheet body of the second lamp;
wherein, for each of the first and second lamps, the flexible sheet body comprises a flexible lens plate having a front surface and a rear surface; and wherein the plurality of light emitters are light emitting diodes printed to the front surface of the flexible lens plate, the rear surface of the flexible lens plate forming the rear surface of the flexible sheet body.

11. The oral treatment device according to claim 10 wherein the flexible lens plate is formed of a biocompatible material.
