Teeth repositioning systems and methods
Systems and methods of repositioning teeth, using one or more appliances for installing on a patient's teeth are described. The appliance includes an arch shaped member; a plurality of spring members coupled to or provided on the arch shaped member; and a plurality of securing members for securing to a corresponding plurality of the patient's teeth on a one-to-one basis, the securing members being supported by the arch shaped member. The arch shaped member and the plurality of springs, together, comprise a two dimensional structure having a length dimension and a width dimension with varying widths along the length dimension, that is bent into a three dimensional structure.
1. An orthodontic appliance for moving a patient's dentition from an original tooth arrangement to an intermediate or final tooth arrangement, the orthodontic appliance comprising:
a single, unitarily-formed member configured to be positioned in a mouth of a patient adjacent a patient's teeth, the member comprising:
a plurality of attachment portions, each configured to be secured to an orthodontic bracket;
a connector configured to extend along the patient's teeth between adjacent attachment portions, wherein the connector includes a spring portion configured to impart a desired force and/or torque on one or both teeth to which the corresponding attachment portions are secured via the orthodontic brackets;
an arch-shaped member configured to extend along the patient's teeth; and
one or more curved extensions having a first end portion at the arch-shaped member and a second end portion at one of the attachment portions.

3. The orthodontic appliance of claim 1 , wherein the connector has a curved shape.
4. The orthodontic appliance of claim 1 , wherein the connector is substantially U-shaped.
5. The orthodontic appliance of claim 1 , wherein the curved extensions form at least one partial loop shape.
6. The orthodontic appliance of claim 1 , wherein the arch-shaped member is substantially rigid.
7. The orthodontic appliance of claim 1 , wherein the member is configured to be positioned in the mouth of the patient adjacent a lingual side of the patient's teeth.
8. The orthodontic appliance of claim 1 , wherein the arch-shaped member is configured to be positioned gingivally of the attachment portions when the orthodontic appliance is installed in the patient's mouth.
9. The orthodontic appliance of claim 1 , wherein the member has a longitudinal axis and is generally arch-shaped along the longitudinal axis.
10. The orthodontic appliance of claim 1 , wherein the member is formed from a sheet of material.
11. An orthodontic appliance for moving a patient's dentition from an original tooth arrangement to an intermediate or final tooth arrangement, the orthodontic appliance comprising:
a single, unitarily-formed member configured to follow an arch of a jaw of a patient, the member having a longitudinal axis, and wherein the member comprises:
a plurality of attachment portions spaced apart along the longitudinal axis of the member, each of the attachment portions configured to be secured to an orthodontic bracket;
a plurality of connectors, each configured to extend along the patient's dental arch between adjacent attachment portions, wherein at least one of the connectors is resiliently flexible and configured to impart a desired force and/or torque on one or both teeth to which the corresponding attachment portions are secured via the orthodontic brackets; and
an arch-shaped member configured to extend along the patient's dental arch; and
a plurality of curved extensions extending between the arch-shaped member and a corresponding one of the attachment portions.
12. The orthodontic appliance of claim 11 , wherein at least one of the connectors comprises a rigid portion extending in a generally mesiodistal direction when the member is secured to the patient's teeth.
13. The orthodontic appliance of claim 11 , wherein at least one of the connectors has a curved shape.
14. The orthodontic appliance of claim 11 , wherein at least one of the connectors is substantially U-shaped.
15. The orthodontic appliance of claim 11 , wherein each of the curved extensions includes at least one partial loop shape.
16. The orthodontic appliance of claim 11 , wherein the arch-shaped member is substantially rigid.
17. The orthodontic appliance of claim 11 , wherein the member is configured to be positioned in the mouth of the patient adjacent a lingual side of the patient's teeth.
18. The orthodontic appliance of claim 11 , wherein the arch-shaped member is configured to be positioned gingivally of the attachment portions when the orthodontic appliance is installed in the patient's mouth.
19. The orthodontic appliance of claim 11 , wherein the member has a longitudinal axis and is generally arch-shaped along the longitudinal axis.
20. The orthodontic appliance of claim 11 , wherein the member is formed from a sheet of material.
21. An orthodontic appliance for moving a patient's dentition from an original tooth arrangement to an intermediate or final tooth arrangement, the orthodontic appliance comprising:
a single, unitarily-formed member configured to be positioned in a mouth of a patient adjacent a patient's teeth, the member comprising:
a plurality of attachment portions, each configured to be secured to an orthodontic bracket;
a connector extending between adjacent attachment portions along the patient's teeth;
a substantially rigid member configured to extend along at least a portion of the patient's jaw; and
a curved extension extending away from the rigid member towards one of the attachment portions, wherein a portion of the curved extension extends in a generally occlusogingival direction when the appliance is installed in the patient's mouth,
wherein the member is configured to be positioned in the mouth of the patient at a lingual side of the patient's teeth.
22. The orthodontic appliance of claim 21 , wherein the connector is resiliently flexible and configured to impart a desired force and/or torque on one or both teeth to which the corresponding attachment portions are secured via the orthodontic brackets.
23. The orthodontic appliance of claim 21 , wherein the connector comprises a rigid portion extending in a generally mesiodistal direction when the member is secured to the patient's teeth.
24. The orthodontic appliance of claim 21 , wherein the connector has a curved shape.
25. The orthodontic appliance of claim 21 , wherein the connector is substantially U-shaped.
26. The orthodontic appliance of claim 21 , wherein the curved extension includes at least one partial loop shape.
27. The orthodontic appliance of claim 21 , wherein the member comprises a shape memory and/or superelastic material.
28. The orthodontic appliance of claim 21 , wherein the member has a longitudinal axis and is generally arch-shaped along the longitudinal axis.
