Abstract

Claims (32)

1 . An orthodontic appliance comprising:

a plurality of orthodontic brackets, each of the plurality of orthodontic brackets configured to be coupled to a tooth of a patient and comprising:

a mesial wall and distal wall with a channel disposed therebetween;

a stop disposed on a gingival end of the orthodontic bracket, the stop having an occlusal-facing wall and a rigid projection, the occlusal-facing wall comprising a mesial sidewall and a distal sidewall, the rigid projection extending occlusally of the mesial and distal sidewalls of the occlusal-facing wall into the channel, the mesial and distal sidewalls of the occlusal-facing wall disposed gingivally of the mesial wall and the distal wall; and

a mesial slot and a distal slot, the mesial slot extending longitudinally in a mesial-distal direction, open in a mesial direction, and disposed between the mesial wall and the mesial sidewall of the occlusal-facing wall of the stop in an occlusal-gingival direction such that the mesial slot is occlusal of the mesial sidewall of the occlusal-facing wall of the stop and gingival of the mesial wall, and the distal slot extending longitudinally in the mesial-distal direction, open in a distal direction, and disposed between the distal wall and the distal sidewall of the occlusal-facing wall of the stop in the occlusal-gingival direction such that the distal slot is occlusal of the distal sidewall of the occlusal-facing wall of the stop and gingival of the distal wall;

an archwire configured to engage with the plurality of orthodontic brackets to move teeth of the patient, the archwire comprising:

a plurality of male fasteners, each of the plurality of male fasteners comprises a mesial leg, a distal leg, and a portion defining an opening, the portion configured to be disposed in the channel of one of the plurality of orthodontic brackets such that the rigid projection is positioned within the opening and the portion defining the opening surrounds at least part of the rigid projection, the mesial leg configured to be disposed in the mesial slot such that the mesial leg is occlusal of the mesial sidewall of the occlusal-facing wall of the stop and gingival of the mesial wall and the distal leg configured to be disposed in the distal slot such that the distal leg is occlusal of the distal sidewall of the occlusal-facing wall of the stop and gingival of the distal wall; and

a plurality of interproximal loops, each of the plurality of interproximal loops disposed between a pair of male fasteners of the plurality of male fasteners.

2 . The orthodontic appliance of claim 1 , wherein the plurality of male fasteners do not slide with respect to the plurality of orthodontic brackets when engaged.

3 . The orthodontic appliance of claim 2 , wherein the mesial and distal walls prevent mesial-distal movement of the plurality of male fasteners.

4 . The orthodontic appliance of claim 1 , wherein the plurality of interproximal loops extend in a gingival direction.

5 . The orthodontic appliance of claim 1 , wherein the channel is open in an occlusal direction.

6 . The orthodontic appliance of claim 5 , wherein the archwire is engaged with the plurality of orthodontic brackets, and wherein the plurality of male fasteners are configured to extend in the occlusal direction beyond the mesial and distal walls.

7 . An orthodontic appliance comprising:

a plurality of orthodontic brackets, each of the plurality of orthodontic brackets configured to be coupled to a tooth of a patient and comprising:

a mesial wall and a distal wall with a channel disposed therebetween;

a stop disposed on a gingival side of the orthodontic bracket, the stop comprising:

an occlusal-facing wall comprising a mesial sidewall and a distal sidewall; and

a portion that extends occlusally of the mesial and distal sidewalls of the occlusal-facing wall in an occlusal direction toward the channel disposed between the mesial and distal walls and occlusally of the mesial and distal sidewalls of the occlusal-facing wall, the mesial and distal sidewalls of the occlusal-facing wall disposed gingivally of the mesial wall and the distal wall; and

a mesial slot and a distal slot, the mesial slot disposed between the mesial wall and the mesial sidewall of the occlusal-facing wall of the stop in an occlusal-gingival direction and the distal slot disposed between the distal wall and distal sidewall of the occlusal-facing wall of the stop in the occlusal-gingival direction;

an archwire configured to engage with the plurality of orthodontic brackets to move teeth of the patient, the archwire comprising:

a plurality of male fasteners, each of the plurality of male fasteners comprises a recess and is configured to be disposed in the channel of one of the plurality of orthodontic brackets such that the portion of the stop that extends in the occlusal direction is positioned within the recess of the male fastener; and

a plurality of interproximal loops extending in a gingival direction, each of the plurality of interproximal loops disposed between a pair of male fasteners of the plurality of male fasteners;

wherein portions of the archwire are configured to be disposed in the mesial slot and the distal slot of each of the plurality of orthodontic brackets such that the portions are simultaneously occlusal of the mesial and distal sidewalls of the occlusal-facing wall of the stop and gingival of the mesial wall or the distal wall.

8 . The orthodontic appliance of claim 7 , wherein the plurality of male fasteners do not slide with respect to the plurality of orthodontic brackets when engaged.

9 . The orthodontic appliance of claim 8 , wherein the mesial and distal walls prevent mesial-distal movement of the plurality of male fasteners.

10 . The orthodontic appliance of claim 7 , wherein the plurality of interproximal loops define gaps along the archwire.

11 . The orthodontic appliance of claim 7 , wherein the plurality of interproximal loops are open in the occlusal direction.

12 . The orthodontic appliance of claim 7 , wherein the portion of the stop that extends in the occlusal direction is rigid.

13 . The orthodontic appliance of claim 7 , wherein the channel is open in the occlusal direction.

14 . The orthodontic appliance of claim 7 , wherein the archwire is engaged with the plurality of orthodontic brackets, and wherein the plurality of male fasteners extend in the occlusal direction beyond the mesial and distal walls.

15 . The orthodontic appliance of claim 7 , wherein the portions of the archwire comprise a mesial leg and a distal leg of each of the plurality of male fasteners.
