Abstract

The present invention relates to orthodontic positioning appliances that represent teeth in desired positions and related systems and methods. An appliance can include teeth receiving cavities shaped to receive and apply a resilient positioning force to a patient'"'"'s teeth. An appliance can include an outer component having a surface representing teeth in desired positions. An outer component can be integral with an appliance. An outer component can be separate and configured to couple with an appliance main body.

Claims

1. A dental positioning device configured to provide an altered appearance to a patient'"'"'s teeth when worn by the patient, the device comprising:

a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient'"'"'s teeth and apply a resilient positioning force to move the patient'"'"'s teeth towards a first planned arrangement of an orthodontic treatment, the appliance comprising a component spanning a portion of an arch of the patient'"'"'s teeth and having an outer surface and further configured to mask the patient'"'"'s teeth while visually depicting the patient'"'"'s teeth in a second planned arrangement from the orthodontic treatment, wherein the orthodontic treatment comprises one or more planned intermediate tooth arrangements and a planned final tooth arrangement, the planned intermediate tooth arrangements designed to incrementally move the patient'"'"'s teeth from an initial arrangement towards the planned final arrangement, the first planned arrangement is one of the one or more planned intermediate arrangements and the second planned arrangement is a different planned intermediate arrangement or the planned final arrangement.

2. The device of claim 1, wherein the appliance comprises one or more material layers.

3. The device of claim 1, wherein the geometry of the outer surface is different from the geometry of the receiving cavities shaped to receive the patient'"'"'s teeth.

4. The device of claim 2, wherein the appliance has a thickness and cavity geometry sufficient to receive and resiliently reposition the patient'"'"'s teeth from a third arrangement to a successive arrangement when worn by the patient.

5. The device of claim 1, wherein the appliance comprises a main body and said component is separate from the main body, said component being configured to couple with the main body to provide the outer surface representing teeth in desired positions.

6. The device of claim 5, wherein said component can be coupled with the main body about one or more bumps, hooks, stepped ramps, or a combination thereof.

7. The device of claim 5, wherein said component is configured to couple with the main body of a second appliance.

8. The device of claim 1, wherein the appliance comprises an opaque material.

9. The device of claim 1, wherein the outer surface comprises a color or shade different than the patient'"'"'s teeth.

10. The device of claim 1, wherein the outer surface represents the patient'"'"'s teeth in selected positions.

11. The device of claim 1, wherein the appliance material thickness decreases toward the posterior portion of the mouth.

12. The device of claim 1, wherein the appliance material thickness between the outer surface and the surface of the patient'"'"'s anterior visible teeth changes between a selected minimum thickness and a selected maximum thickness.

13. The device of claim 1, wherein the surface representing teeth comprises a plurality of regions representing individual teeth;

where one or more of the regions have a different orientation than that of the associated cavity.

14. A system for orthodontically treating a patient'"'"'s teeth, comprising:

a plurality of orthodontic tooth positioning appliances for a patient'"'"'s teeth, each appliance of the plurality having different teeth receiving cavities shaped to directly receive at least some of the patient'"'"'s teeth and resiliently reposition the patient'"'"'s teeth from a first arrangement to a successive planned arrangement from an orthodontic treatment, at least one appliance further comprising a component spanning a portion of an arch of the patient'"'"'s teeth and having an outer surface and further configured to mask the patient'"'"'s teeth while visually depicting the patient'"'"'s teeth in a second planned arrangement from the orthodontic treatment, wherein the orthodontic treatment comprises one or more planned intermediate tooth arrangements and a planned final tooth arrangement, the planned intermediate tooth arrangements designed to incrementally move the patient'"'"'s teeth from an initial arrangement towards the planned final arrangement, the successive planned arrangement is one of the one or more planned intermediate arrangements and the second planned arrangement is a different planned intermediate arrangement or the planned final arrangement.

15. The system of claim 14, wherein each appliance comprises an outer component having a surface representing the patient'"'"'s teeth in desired positions.

16. The system of claim 15, wherein at least two appliances represent the patient'"'"'s teeth in different positions.

17. The system of claim 15, wherein the outer component is integral to the appliance.

18. The system of claim 15, wherein the outer component is configured to couple with at least one of the appliances.

19. The system of claim 14, wherein the appliance material thickness of at least one appliance decreases toward the posterior portion of the mouth.

20. The system of claim 19, wherein the at least one appliance material thickness between the outer surface and the surface of the patient'"'"'s anterior visible teeth changes between a selected minimum thickness and a selected maximum thickness.

21. The system of claim 15, wherein the outer component surface does not change as the patient'"'"'s teeth move from the first arrangement to the successive arrangement.

22. The system of claim 14, wherein the color of the outer surface is different than the color of the patient'"'"'s teeth.

23. The system of claim 14, wherein the outer surface creates the appearance that the teeth are in prescribed positions.

24. A kit for moving teeth that presents an appearance of teeth in desired positions comprising:

two or more orthodontic tooth positioning appliances, each appliance having different teeth receiving cavities shaped to directly receive at least some of the patient'"'"'s teeth and resiliently reposition the patient'"'"'s teeth from a first arrangement to a successive planned arrangement from an orthodontic treatment; and

an outer component having a surface masking the patient'"'"'s teeth while visually depicting the patient'"'"'s teeth in a second planned arrangement from the orthodontic treatment, wherein the outer component couples with at least one of the appliances and spans a portion of an arch defined by the patient'"'"'s teeth, and wherein the orthodontic treatment comprises one or more planned intermediate tooth arrangements and a planned final tooth arrangement, the planned intermediate tooth arrangements designed to incrementally move the patient'"'"'s teeth from an initial arrangement towards the planned final arrangement, the successive planned arrangement is one of the one or more planned intermediate arrangements and the second planned arrangement is a different planned intermediate arrangement or the planned final arrangement.

25. A dental positioning device configured to provide an altered appearance to a patient'"'"'s teeth when worn by the patient, the device comprising:

a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient'"'"'s teeth and apply a resilient positioning force to move the patient'"'"'s teeth towards a first planned arrangement of an orthodontic treatment, the appliance comprising a component spanning a portion of an arch of the patient'"'"'s teeth and having an outer surface, the component configured to mask the patient'"'"'s teeth while visually depicting the patient'"'"'s teeth in a second planned arrangement from the orthodontic treatment, and the component comprising either a portion integral to the appliance or a separate outer component configured to couple to the appliance, wherein the orthodontic treatment comprises one or more planned intermediate tooth arrangements and a planned final tooth arrangement, the planned intermediate tooth arrangements designed to incrementally move the patient'"'"'s teeth from an initial arrangement towards the planned final arrangement, the first planned arrangement is one of the planned intermediate arrangements and the second planned arrangement is a different planned intermediate arrangement or the planned final arrangement.
