Abstract

An orthodontic appliance may include an archwire and multiple orthodontic brackets. The archwire may fit within a human mouth and contain multiple male connectors. Each orthodontic bracket may have a configuration that facilitates attaching the orthodontic bracket to a single tooth. Each orthodontic bracket may allow one of the male connectors to be locked into the orthodontic bracket with a snapping action. The male connector may be unable to slide with respect to the orthodontic bracket after being locked in the orthodontic bracket. A manual unlocking action may allow the male connector to disengage from the orthodontic bracket.

Claims (25)

1. A method of moving teeth, comprising:

obtaining imaging data of a patient's teeth;

providing a single continuous customized archwire having a curved shape configured to follow a dental arch of the patient and configured to move the patient's teeth to a pre-determined configuration, the archwire being fabricated from a virtual set-up utilizing the image data obtained from the patient's teeth, and configured to move the patient's teeth from an initial arrangement to the pre-determined configuration,

wherein the archwire comprises a first non-deflected configuration when the teeth are in the pre-determined configuration and a second deflected configuration when the teeth are in the initial arrangement;

wherein the single continuous customized archwire comprises a plurality of male loops and a plurality of interproximal looped structures, each male loop corresponding to each and every tooth of the dental arch of the patient and only a single interproximal looped structure of the plurality of interproximal looped structures being positioned between each and every male loop and corresponding to an interdental space in between each and every tooth of the dental arch; and

wherein the curved shape of the archwire defines a longitudinal axis and wherein each interproximal loop comprises a mesial point on the longitudinal axis, a distal point on the longitudinal axis, and an incomplete loop between the mesial point and the distal point extending away from the longitudinal axis, the incomplete loop defining a gap along the longitudinal axis forming an opening into the incomplete loop, the opening configured to face in a gingival or an occlusal direction; and

activating the archwire, wherein activating the archwire comprises deflecting the archwire from the first configuration to the second configuration, and attaching each male loop of the plurality of male loops to corresponding brackets attached to each and every tooth of the dental arch, thereby allowing the interproximal looped structures to impart forces on the teeth thereby moving the teeth toward the pre-determined configuration as the archwire moves from the second configuration back to the first configuration, wherein the archwire does not slide with respect to the brackets when each of the male loops are attached to the corresponding brackets.

2. The method of claim 1 , wherein activating the archwire leads to mesio-distal tooth movement for at least some of the teeth.

3. The method of claim 1 , wherein activating the archwire leads to occlusal-gingival tooth movement for at least some of the teeth.

4. The method of claim 1 , wherein activating the archwire leads to facio-lingual tooth movement for at least some of the teeth.

5. The method of claim 1 , wherein the interproximal looped structures comprises a single loop shape.

6. The method of claim 1 , wherein the interproximal looped structures comprises a boot shaped loop.

7. The method of claim 1 , wherein the interproximal looped structures comprises a teardrop shaped loop.

8. The method of claim 1 , wherein the brackets comprise self-ligating brackets.

9. The method of claim 1 , wherein the brackets comprise twin brackets.

10. The method of claim 1 , wherein the brackets comprise single-wing brackets.

11. The method of claim 1 , wherein the brackets comprise ribbon arch brackets.

12. The method of claim 1 , wherein the single continuous customized archwire comprises a shape memory material.

13. A method of moving teeth, comprising:

obtaining imaging data of a patient's teeth;

providing a single continuous customized archwire having a curved shape configured to follow a dental arch of the patient and configured to move the patient's teeth to a pre-determined configuration, the archwire being fabricated from a virtual set-up utilizing the image data obtained from the patient's teeth, and configured to move the patient's teeth from an initial arrangement to the pre-determined configuration,

wherein the archwire comprises a first non-deflected configuration when the teeth are in the pre-determined configuration and a second deflected configuration when the teeth are in the initial arrangement;

wherein the single continuous customized archwire comprises a plurality of male loops and a plurality of interproximal looped structures, each male loop corresponding to each and every tooth of the dental arch of the patient and only a single interproximal looped structure of the plurality of interproximal looped structures being positioned between each and every male loop and corresponding to an interdental space in between each and every tooth of the dental arch; and

wherein the curved shape of the archwire defines a longitudinal axis and wherein each interproximal loop comprises a mesial point on the longitudinal axis, a distal point on the longitudinal axis, and an incomplete loop extending away from the longitudinal axis between the mesial point and the distal point, the archwire extending along the incomplete loop from the mesial point to the distal point without forming a complete loop; and

activating the archwire, wherein activating the archwire comprises deflecting the archwire from the first configuration to the second configuration, and attaching each male loop of the plurality of male loops to corresponding brackets attached to each and every tooth of the dental arch, thereby allowing the interproximal looped structures to impart forces on the teeth thereby moving the teeth toward the pre-determined configuration as the archwire moves from the second configuration back to the first configuration, wherein the archwire does not slide with respect to the brackets when each of the male loops are attached to the corresponding brackets.
