Abstract

Methods, systems, and apparatus's for improving orthodontic treatments. In an embodiment, an orthodontic system including a tactile object is provided for modulating an engagement between a tooth attachment and an orthodontic appliance.

First claim

What is claimed is:

1. A system for orthodontically positioning a patient's tooth, the system comprising:
an attachment adapted to be attached to the patient's tooth;
a patient removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to receive and apply a resilient positioning force to the patient's teeth, at least one of the teeth receiving cavities comprising an attachment receiving well having a cross sectional shape that conforms to a cross sectional shape of the attachment and including an upper surface and a lower surface and being configured to engage with and receive therein the attachment when the patient removable orthodontic tooth positioning appliance is worn by the patient and a force is being applied to the attachment, the upper surface facing the lower surface;
a first tactile object extending from and coupled to the upper surface of the attachment receiving well; and
a second tactile object, separate from the first tactile object, extending from and coupled to the lower surface of the attachment receiving well;
wherein the first tactile object and the second tactile object modulate engagement between the attachment and the attachment receiving well when the patient removable orthodontic tooth positioning appliance is worn by the patient;
wherein the first tactile object and the second tactile object are each made from a material having an elastic modulus less than an elastic modulus of a material from which the patient removable orthodontic tooth positioning appliance is formed;
wherein the first tactile object is shaped according to a shape of the upper surface of the attachment receiving well to provide a locking fit between the patient removable orthodontic tooth positioning appliance and the attachment; and
wherein the second tactile object is shaped according to a shape of the lower surface of the attachment receiving well to provide a locking fit between the patient removable orthodontic tooth positioning appliance and the attachment.

2. The system of claim 1 , wherein the first tactile object and the second tactile object are made from the same material.

3. The system of claim 1 , wherein the first tactile object and the second tactile object are made from different material.

4. The system of claim 1 , wherein the first tactile object and the second tactile object have different malleability.

5. The system of claim 1 , further comprising a third tactile object including first and second portions extending from the attachment receiving well.

6. The system of claim 5 , wherein the first and second portions apply a reciprocal force to the attachment.

7. An orthodontic positioning appliance comprising:
a patient removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to receive and apply a resilient positioning force to the patient's teeth, where at least one of the teeth receiving cavities includes an attachment receiving well shaped to engage with and apply a force to an attachment adapted to be disposed on the patient's tooth and including an upper surface and a lower surface, the upper surface facing the lower surface;
a first tactile object extending from and coupled to the upper surface of the attachment receiving well; and
a second tactile object, separate from the first tactile object, extending from and coupled to the lower surface of the attachment receiving well;
wherein the first tactile object and the second tactile object modulate the engagement between the attachment and the attachment receiving well and the application of force between a surface of the attachment and the patient removable orthodontic tooth positioning appliance, wherein the patient removable orthodontic tooth positioning appliance is worn by the patient;
wherein the first tactile object and the second tactile object each having an elastic modulus less than an elastic modulus of the patient removable orthodontic tooth positioning appliance;
wherein the first tactile object is formed in a shape of the upper surface of the attachment receiving well to provide a locking fit between the patient removable orthodontic tooth positioning appliance and the attachment; and
wherein the second tactile object is formed in a shape of the lower surface of the attachment receiving well to provide a locking fit between the patient removable orthodontic tooth positioning appliance and the attachment.

8. The orthodontic positioning appliance of claim 7 , wherein the first tactile object and the second tactile object are made from the same material.

9. The orthodontic positioning appliance of claim 7 , wherein the first tactile object and the second tactile object are made from different material.

10. The orthodontic positioning appliance of claim 7 , wherein the first tactile object and the second tactile object have different malleability.

11. The orthodontic positioning appliance of claim 7 , further comprising a third tactile object including first and second portions extending from the attachment receiving well.

12. The orthodontic positioning appliance of claim 11 , wherein the first and second portions apply a reciprocal force to the attachment.

13. A method for applying a tooth positioning force to the dentition of a patient, the method comprising:
providing an attachment adapted for disposal on at least one of the patient's teeth;
providing a patient removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to receive and apply a resilient positioning force to the patient's teeth, where at least one of the teeth receiving cavities includes an attachment receiving well having a cross sectional shape that conforms to a cross sectional shape of the attachment and including an upper surface and a lower surface and being configured to engage with and receive therein the attachment when the patient removable orthodontic tooth positioning appliance is worn by the patient and a force is being applied to the attachment, the upper surface facing the lower surface; and
coupling a first tactile object to the upper surface of the attachment receiving well and a second tactile object, separate from the first tactile object, to the lower surface of the attachment receiving well, such that the first tactile object and the second tactile object modulate engagement between the attachment and the attachment receiving well when the patient removable orthodontic tooth positioning appliance is worn by the patient;
wherein the first tactile object and the second tactile object are each made from a material having an elastic modulus less than an elastic modulus of a material from which the patient removable orthodontic tooth positioning appliance is formed;
wherein the first tactile object is shaped according to a shape of the upper surface of the attachment receiving well to provide a locking fit between the patient removable orthodontic tooth positioning appliance and the attachment;
wherein the second tactile object is shaped according to a shape of the lower surface of the attachment receiving well to provide a locking fit between the patient removable orthodontic tooth positioning appliance and the attachment; and
wherein the first tactile object and the second tactile object each have a respective uniform thickness.

14. The method of claim 13 , wherein the first tactile object and the second tactile object are made from the same material.

15. The method of claim 13 , wherein the first tactile object and the second tactile object are made from different material.

16. The method of claim 13 , wherein the first tactil
