Abstract

Embodiments are provided for a patterned dental positioning appliance. One method embodiment includes receiving a dental mold of a patient'"'"'s dentition, applying a pattern to a portion of the dental mold, and applying a material to the dental mold to form the removable dental positioning appliance that includes either the pattern on the portion of the dental mold or an inverse thereof.

Claims

1. A removable dental positioning appliance, comprising:

a body formed from one or more polymeric materials, the body including;

one or more interior surfaces shaped to receive and to exert one or more first repositioning forces on one or more teeth to reposition the one or more teeth from a first arrangement toward a successive arrangement;

a first portion having a first thickness, the first portion including a first pattern formed on the one or more interior surfaces, the first pattern shaped to exert one or more second repositioning forces to a particular portion of on at least one tooth of the one or more teeth, wherein the first pattern is formed from a textile material placed into a mold used to thermoform the removable dental positioning appliance; and

a second portion integral with the first portion, the second portion having a second thickness greater than the first thickness.

2. The removable dental positioning appliance of claim 1, wherein the first pattern is designed to improve application of the one or more second repositioning forces in one or more directions on the at least one tooth when the removable dental positioning appliance is placed over the one or more teeth.

3. The removable dental positioning appliance of claim 2, wherein the first pattern is designed to improve application of the one or more second repositioning forces directly on the at least one tooth.

4. The removable dental positioning appliance of claim 2, further comprising a third portion distinct from the first portion and the second portion, the third portion having a third thickness and the third portion comprising a second pattern formed on the interior surface, the second pattern shaped to exert one or more third repositioning forces to a particular portion of at least another tooth of the one or more teeth.

5. The removable dental positioning appliance of claim 1, wherein the first pattern is formed from a textile material attached to an inner surface of a mold used to form the removable dental positioning appliance.

6. The removable dental positioning appliance of claim 1, wherein the first pattern is located on a lingual portion or a buccal portion of the removable dental positioning appliance.

7. The removable dental positioning appliance of claim 1, wherein the first pattern strengthens the first portion of the removable dental positioning appliance relative to the second portion.

8. A system of removable dental positioning appliances, comprising:

a plurality of successive removable dental positioning appliances, each of the plurality of successive removable dental positioning appliances having a body formed from one or more polymeric materials, a body of at least one successive removable dental positioning appliance of the plurality of successive removable dental positioning appliances including;

an inner surface shaped to receive and to exert one or more repositioning forces on one or more teeth to reposition the one or more teeth from a first arrangement toward a successive arrangement;

a first portion having a first thickness, the first portion including a first pattern formed on the interior surface, the first portion shaped to focus contact force imparted on the one or more teeth at one or more particular locations corresponding to the first pattern, wherein the first pattern is formed from a textile material placed into molds used to thermoform the removable dental positioning appliances; and

a second portion integrally with the first portion, the second portion having a thickness greater than the first thickness.

9. The system of claim 8, wherein the first pattern on two or more of the successive removable dental positioning appliances are configured to focus a contact force.

10. The system of claim 8, wherein the inner surface of each successive removable dental positioning appliance includes a different pattern of a plurality of patterns.

11. The system of claim 10, wherein the plurality of patterns includes a mesh pattern and wherein a feature imparting the contact force comprises an intersection of two mesh ligaments.

12. The system of claim 8, wherein the first pattern includes raised shapes and wherein a feature imparting the contacting force is the raised shapes.

13. The system of claim 8, wherein the first pattern on the plurality of successive removable dental positioning appliances isolates a force on the patient'"'"'s teeth to move the patient'"'"'s teeth an incremental amount toward the successive arrangement.

14. A removable dental positioning appliance, comprising:

a body formed from one or more polymeric materials and having an inner surface having a plurality of inner cavities configured to contact a patient'"'"'s teeth, such that the inner surface includes a first portion having a first thickness and a second portion integrally with the first portion and having a second thickness greater than the first thickness, the first portion configured to form one or more corresponding patterns designed to affect application of a dental repositioning force from the removable dental positioning appliance directly on at least one tooth of the patient, wherein the one or more corresponding patterns are formed from a textile material placed into the removable dental positioning appliance during a thermoforming process used to form the removable dental positioning appliance.

15. The removable dental positioning appliance of claim 14, wherein a pre-patterned material that was used to form the one or more corresponding patterns on the inner surface is not attached to the removable dental positioning appliance.

16. The removable dental positioning appliance of claim 14, wherein the one or more corresponding patterns includes a first pattern on a first portion of the removable dental positioning appliance and a second pattern on a second portion of the removable dental positioning appliance.

17. The removable dental positioning appliance of claim 14, wherein the one or more corresponding patterns is formed of repeated elements of one or more of straight lines, curved lines, uniform circumference bumps, and non-uniform circumference bumps.

18. The removable dental positioning appliance of claim 14, wherein an outer surface of the body does not include the one or more corresponding patterns.

19. A removable dental positioning appliance, comprising:

a body formed from one or more polymeric materials, the body including;

one or more interior surfaces shaped to receive and to exert one or more first repositioning forces on one or more teeth to reposition the one or more teeth from a first arrangement toward a successive arrangement;

a first portion having a first thickness, the first portion including a first pattern formed on the one or more interior surfaces, the first pattern shaped to exert one or more second repositioning forces to a particular portion of on at least one tooth of the one or more teeth, wherein the first pattern is formed from a textile material placed into the removable dental positioning appliance during a thermoforming process used to form the removable dental positioning appliance; and

a second portion integral with the first portion, the second portion having a second thickness greater than the first thickness.

20. A system of removable dental positioning appliances, comprising:

a plurality of successive removable dental positioning appliances, each of the plurality of successive removable dental positioning appliances having a body formed from one or more polymeric materials, a body of the at least one successive removable dental positioning appliance of the plurality of successive removable dental positioning appliances including;

an inner surface shaped to receive and to exert one or more repositioning forces on one or more teeth to reposition the one or more teeth from a first arrangement toward a successive arrangement;

a first portion having a first thickness, the first portion including a first pattern formed on the inner surface, the first portion shaped to focus contact force imparted on the one or more teeth at one or more particular locations corresponding to the first pattern, wherein the first pattern is formed from a textile material placed into the removable dental positioning appliances during a thermoforming process used to form the removable dental positioning appliances; and

a second portion integrally with the first portion, the second portion having a thickness greater than the first thickness.
