Abstract

An appliance fabricated to improve the appearance of a patient'"'"'s smile includes a plurality of simulated teeth. The interior surfaces of each of the teeth closely fits and conforms to the surface of a patient'"'"'s real teeth while the outer surfaces of each of the simulated teeth has an ideal surface configuration. The dental appliance provides the patient with the appearance of a perfect set of teeth and an ideal smile without a need to alter the dental structure of the patient'"'"'s teeth.

Claims

1. A dental appliance for improving appearance of a patient'"'"'s teeth, comprising:

a continuous wall that engages facial and lingual surfaces of the patient'"'"'s teeth and provides a visual impression including at least one of a selected color and a selected contour, the wall comprising;

an inner surface adapted to engage with the facial and lingual surfaces of the patient'"'"'s teeth;

an outer surface comprising a tongue side arch and a visible cheek side arch, each of the arches extending from a first posterior location to an anterior portion and then to a second posterior location; and

wherein thickness of the wall between the inner and outer surfaces on the cheek side arch gradually and continuously increases toward the first and second posterior locations relative to the anterior location.

2. The dental appliance recited in claim 1, wherein the inner surface is further adapted to engage occlusal surfaces of the patient'"'"'s teeth.

3. The dental appliance recited in claim 1, wherein the wall is configured to build out a buccal aspect of the dental appliance from the anterior location to one of the first and second posterior locations.

4. The dental appliance recited in claim 1, wherein the visual impression further comprises a selected shade.

5. The dental appliance recited in claim 4, further comprising means for affixing the inner surface of the wall to the patient'"'"'s teeth.

6. The dental appliance recited in claim 1, wherein the dental appliance is comprised of acetyl resin material.

7. The dental appliance recited in claim 1, wherein the wall further comprises a first area corresponding to a lateral incisor of the patient'"'"'s teeth and a second area corresponding to a front tooth of the patient'"'"'s teeth.

8. The dental appliance recited in claim 7, wherein the thickness of the wall between the inner and outer surfaces on the cheek side arch for the first area is greater than the corresponding thickness for the second area.

9. The dental appliance recited in claim 1, wherein the outer surface of the visible cheek side arch is configured as a plurality of simulated teeth.

10. The dental appliance recited in claim 9, wherein the plurality of simulated teeth provides the visual impression.

11. A dental appliance for improving appearance of a patient'"'"'s teeth, comprising:

a continuous wall that engages facial and lingual surfaces of the patient'"'"'s teeth and provides a visual impression including at least one of a selected color and a selected contour, the wall comprising;

an inner surface adapted to engage with the facial and lingual surfaces of the patient'"'"'s teeth;

an outer surface comprising a tongue side arch and a visible cheek side arch, each of the arches extending from a first posterior location to an anterior portion and then to a second posterior location;

means for affixing the inner surface of the wall to the Patient'"'"'s teeth; and

wherein thickness of the wall between the inner and outer surfaces on the cheek side arch gradually and continuously increases toward the first and second posterior locations relative to the anterior location.

12. The dental appliance recited in claim 11, wherein the inner surface is further adapted to engage occlusal surfaces of the patient'"'"'s teeth.

13. The dental appliance recited in claim 11, wherein the wall is configured to build out a buccal aspect of the dental appliance from the anterior location to one of the first and second posterior locations.

14. The dental appliance recited in claim 11, wherein the visual impression further comprises a selected shade.

15. The dental appliance recited in claim 11, wherein the dental appliance is comprised of acetyl resin material.

16. The dental appliance recited in claim 11, wherein the wall further comprises a first area corresponding to a lateral incisor of the patient'"'"'s teeth and a second area corresponding to a front tooth of the patient'"'"'s teeth.

17. The dental appliance recited in claim 16, wherein the thickness of the wall between the inner and outer surfaces on the cheek side arch for the first area is greater than the corresponding thickness for the second area.

18. The dental appliance recited in claim 11, wherein the outer surface of the visible cheek side arch is configured as a plurality of simulated teeth.

19. The dental appliance recited in claim 18, wherein the plurality of simulated teeth provides the visual impression.

20. A dental appliance for improving appearance of a patient'"'"'s teeth, comprising:

a continuous wall that engages facial and lingual surfaces of the patient'"'"'s teeth, extends from a gingival margin of the patient'"'"'s teeth, and provides a visual impression including at least one of a selected color and a selected contour, the wall comprising;

an inner surface adapted to engage with the facial and lingual surfaces of the patient'"'"'s teeth;

an outer surface comprising a tongue side arch and a visible cheek side arch, each of the arches extending from a first posterior location to an anterior portion and then to a second posterior location; and

wherein thickness of the continuous wall between the inner and outer surfaces on the cheek side arch gradually and continuously increases toward the first and second posterior locations relative to the anterior location.

21. The dental appliance of claim 20, wherein the continuous wall exposes at least a portion of an interproximal space between the patient'"'"'s teeth when the dental appliance is placed on the patient'"'"'s teeth.

22. The dental appliance of claim 20, wherein the continuous wall exposes at least a portion of an interproximal space between at least two of the patient'"'"'s teeth when the dental appliance is placed on the patient'"'"'s teeth.

23. The dental appliance of claim 20, wherein the continuous wall further comprises a first area corresponding to a lateral incisor of the patient'"'"'s teeth and a second area corresponding to a front tooth of the patient'"'"'s teeth.

24. The dental appliance of claim 23, wherein a thickness of the continuous wall between the inner and outer surfaces on the cheek side arch for the first area is greater than a corresponding thickness for the second area.

25. The dental appliance recited in claim 20, wherein the outer surface of the visible cheek side arch is configured as a plurality of simulated teeth.

26. The dental appliance recited in claims 25, wherein the plurality of simulated teeth provides the visual impression.

27. A dental appliance for improving appearance of a Patient'"'"'s teeth, comprising:

a continuous wall that engages facial and lingual surfaces of the patient'"'"'s teeth and provides a visual impression including at least one of a selected color and a selected contour, the wall comprising;

an inner surface adapted to engage with the facial and lingual surfaces of the patient'"'"'s teeth;

an outer surface comprising a tongue side arch and a visible cheek side arch, each of the arches extending from a first posterior location to an anterior portion and then to a second posterior location; and

wherein thickness of the wall between the inner and outer surfaces on the cheek side arch gradually and continuously increases toward the first and second posterior locations relative to the anterior location, and wherein the outer surface of the visible cheek side arch is configured as a plurality of simulated teeth.
