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 (42)

1. A system comprising:

a plurality of orthodontic appliances configured to be worn sequentially, at least one of the plurality of orthodontic appliances including:

an integral shell comprising a tooth facing surface and an outward facing surface, wherein:

the tooth facing surface defines teeth receiving cavities with inner surface geometries shaped to receive and resiliently reposition a patient's teeth toward at least one intermediate arrangement from a plurality of intermediate arrangements, and

the outward facing surface has a first outer portion with an outer surface geometry shaped to:

depict a first portion of the teeth according to a desired arrangement corresponding to an intended outcome of an orthodontic treatment plan, the desired arrangement being different from the at least one intermediate arrangement; and

mask an actual arrangement of the patient's teeth when the at least one of the plurality of orthodontic appliances is worn.

2. The system of claim 1 , wherein the outward facing surface of the at least one of the plurality of orthodontic appliances is configured to provide a protective arrangement configured to reduce a force level provided to the patient, enhance dispersion of a localized impact force, or some combination thereof.

3. The system of claim 1 , wherein the desired arrangement corresponding to the intended outcome of the orthodontic treatment plan corresponds with a prescribed arrangement.

4. The system of claim 1 , wherein the outward facing surface of the at least one of the plurality of orthodontic appliances is configured to depict a colored arrangement comprising colored segments.

5. The system of claim 1 , wherein the actual arrangement of the patient's teeth includes a malocclusion condition being treated by the system.

6. The system of claim 1 , wherein the first outer portion of the outward facing surface spans the anterior teeth of the patient when a respective one of the plurality of orthodontic appliances is worn.

7. The system of claim 1 , wherein the outward facing surface comprises a color or shade different than the patient's teeth.

8. The system of claim 1 , wherein the desired arrangement corresponds to an intended final arrangement of the patient's teeth according to the treatment plan.

9. The system of claim 1 , wherein an appliance material thickness of each of the plurality of orthodontic appliances decreases toward a posterior portion of the at least one of the plurality of orthodontic appliances.

10. A device comprising:

an integral orthodontic appliance shell including a tooth facing surface and an outward facing surface, wherein:

the tooth facing surface has teeth receiving cavities with inner surface geometries shaped to receive and resiliently reposition a patient's teeth toward at least one intermediate arrangement from a plurality of intermediate arrangements; and

the outward facing surface has a first outer portion with an outer surface geometry shaped to:

depict a first portion of the teeth according to a desired arrangement corresponding to an intended outcome of an orthodontic treatment plan, the desired arrangement being different from the at least one intermediate arrangement; and

mask an actual arrangement of the patient's teeth when the orthodontic appliance shell is worn.

11. The device of claim 10 , wherein the outward facing surface is configured to provide a protective arrangement configured to reduce a force level provided to the patient, enhance dispersion of a localized impact force, or some combination thereof.

12. The device of claim 10 , wherein the outward facing surface is configured to provide a prescribed arrangement corresponding to the intended outcome of the orthodontic treatment plan.

13. The device of claim 10 , wherein the outward facing surface is configured to depict a colored arrangement comprising colored segments.

14. The device of claim 10 , wherein the desired arrangement corresponds to an intended final arrangement of the patient's teeth according to the treatment plan.

15. The device of claim 10 , wherein the outward facing surface comprises a color or shade different than the patient's teeth.

16. The device of claim 10 , wherein the actual arrangement of the patient's teeth includes a malocclusion condition being treated by the system.

17. A system comprising:

a plurality of orthodontic appliances, each of the plurality of orthodontic appliances including:

a shell comprising a tooth facing surface and an outward facing surface, wherein:

the tooth facing surface defines teeth receiving cavities with inner surface geometries shaped to receive and resiliently reposition a patient's teeth toward at least one intermediate arrangement from a plurality of intermediate arrangements,

the outward facing surface has a first outer portion with an outer surface geometry shaped to:

depict a first portion of the teeth according to a desired colored arrangement comprising colored segments;

depict the first portion of the teeth according to a desired arrangement corresponding to an intended outcome of an orthodontic treatment plan; and

mask an actual arrangement of the patient's teeth,

wherein the outer surface geometry is the same for each of the plurality of orthodontic appliances, and each shell of the plurality of orthodontic appliances has a different inner surface geometry from another shell of the plurality of orthodontic appliances.

18. The system of claim 17 , wherein the outward facing surface of at least one of the plurality of orthodontic appliances is configured to provide a protective arrangement configured to reduce a force level provided to the patient, enhance dispersion of a localized impact force, or some combination thereof.

19. The system of claim 17 , wherein the outward facing surface of at least one of the plurality of orthodontic appliances is configured to provide a prescribed arrangement corresponding to the intended outcome of the orthodontic treatment plan.

20. The system of claim 17 , wherein the outward facing surface of at least one of the plurality of orthodontic appliances is configured to depict an intended final arrangement of the patient's teeth according to the treatment plan.

21. The system of claim 17 , wherein the colored segments comprise a color or shade different than the patient's teeth.

22. The system of claim 17 , wherein desired arrangement corresponding to the intended outcome of the orthodontic treatment plan corresponds with a prescribed arrangement.

23. The system of claim 17 , wherein the actual arrangement of the patient's teeth includes a malocclusion condition being treated by the system.
