[0022] FIG. 1 is a perspective view of an orthodontic appliance 100 in accordance with an example embodiment of the present disclosure. In the example embodiment, orthodontic appliance 100 includes a bonding surface 102 and an opposing face 104 and a body 106 extending therebetween. Bonding surface 102 is configured to be adhered to a surface of a tooth (not shown in FIG. 1). Face 104 is configured to be exposed to an inner oral surface of a mouth of a user. Accordingly, surface 102, face 104, body 106 and other surfaces associated with orthodontic appliance 100 are configured to smooth and generally rounded to prevent catching or cutting into the inner oral surface of the user. Body 106 includes a groove 108 that extends from a lower surface 110 of body 106 parallel between surface 102 and face 104. In the example embodiment, groove 108 includes three archwire stays, a first archwire stay 112, a second archwire stay 114, and a third archwire stay 116. Each of archwire stays 112, 114, and 116 are configured to receive archwires of progressively larger size. Each of archwire stays 112, 114, and 116 are also shaped to be complementary to a shape of an archwire used with that archwire stay 112, 114, or 116. For example, a round archwire 118 is illustrated as fitted into archwire stay 112. However, archwire stay 112 could be shaped differently and archwire 118 could be also shaped to match the different shape of archwire stay 112. Archwire stays 114 and 116 are illustrated as being rectangularly-shaped. Specifically, archwire stays 114 and 116 are illustrated as being square-shaped. In various embodiments, archwire stays 114 and 116 can be shaped in other shapes. A relatively small archwire 118, which may be round in cross section, may be used to facilitate passive ligation and thus provide quicker leveling and aligning of the teeth during an initial stage of treatment. During a later stage of treatment, it may be desirable to more precisely control the orientation of one or more of the teeth. In this regard, archwire 118 may be forcibly held or fully seated in contact with archwire stays 112, 114, or 116 to provide control of rotation on one or more of the particular tooth. This is often referred to as “active ligation.” The clinician may use a relatively large archwire, which may be rectangular as opposed to round, to substantially fill the space within the archwire stays, for example, archwire stays 114 or 116. The larger archwire may then contact all surfaces of archwire stays 114 or 116 at the same time to enhance the clinician's control of rotation of and torque on the tooth.

[0023] FIG. 2 is a plan view of for example, a lower jaw 200 of a user illustrating a row of teeth 202 of the user. In the example embodiment, orthodontic appliance 100 is adhered to a front surface 204 of one or more of teeth 202. Archwire 118 is illustrated as passing from orthodontic appliance 100 on each tooth 202 to orthodontic appliance 100 on adjacent teeth 202.

[0024] FIG. 3 is a side elevation view of orthodontic appliance 100 in accordance with an example embodiment of the present disclosure. In the example embodiment, orthodontic appliance 100 is adhered to tooth 202 using an adhesive 302. Groove 108 is illustrated with archwire stays 112, 114, and 116. Archwire stay 112 includes a diameter 304 that in some embodiments is approximately 0.009 inches to approximately 0.025 inches. Archwire stay 114 includes a width 306 that is perpendicular to bonding surface 102. In some embodiments, width 306 is a distance that is greater than diameter 304. Archwire stay 116 includes a width 308 that is perpendicular to bonding surface 102. In some embodiments, width 308 is a distance that is greater than width 306. The progressively smaller size of archwire stays 116 to 112 prevents an archwire, such as archwire 118 from being able to fit in an incorrect archwire stay 112, 114, or 116. In various embodiments, channels 310 that connect archwire stays 112, 114, and 116 are sized smaller than archwire stays 112, 114, and 116. To permit archwire 118 to pass through groove 108 to a proper archwire stay of archwire stays 112, 114, and 116, orthodontic appliance 100 includes a resiliency about archwire stay 112 such that groove 108 is able to open slightly when a lateral force is applied to a sidewall 312 of orthodontic appliance 100. The force may be applied by archwire 118 as archwire 118 is inserted into groove 108 and pushed into the proper stay of possible archwire stays 112, 114, and 116. When archwire 118 is positioned within the proper archwire stay 112, 114, or 116, orthodontic appliance 100 resiliently snaps back to its original position.

[0025] FIG. 4 is a side elevation view of orthodontic appliance 100 in accordance with another example embodiment of the present disclosure. In this example embodiment, one or more of archwire stays 112, 114, and 116 includes a convergent cross-section 402 configured to facilitate guiding archwire 118 through groove 108. In various embodiments, convergent cross-section 402 may extend an entire length 404 of channel 310 or may extend for only a portion of length 404. In the example embodiment, orthodontic appliance 100 also includes one or more accessory attachment tabs 406 and 408. Accessory attachment tabs 406 and 408 are configured to receive, for example, elastic bands 410 used to secure additional devices 412, such as, but not limited to orthodontic appliances and/or entertainment and fashion devices.

[0026] Archwire stays 112, 114, and 116 permit changing of archwire 118 during treatment without removing and reinstalling orthodontic appliance 100 to accommodate different sizes of archwire 118. Typically, archwire 118 is changed often during treatment. Treatment involves slowly moving from small archwire 118 that are round in cross-section to relatively heavy thick wires that are rectangularly-shaped. By using different shaped archwire 118, forces acting on tooth 202 can be tailored to move tooth 202 to a predetermined position. When a better alignment of the teeth is accomplished, archwire 118 is changed to a material that can be bent, like stainless steel. Bending a strong archwire 118 permits fine-tuning of the occlusion.

[0027] FIG. 5 is a flowchart of a method 500 of aligning teeth. In the example embodiment, method 500 includes adhering 502 a plurality of orthodontic appliances to a surface of respective adjacent teeth wherein each orthodontic appliance of said plurality of orthodontic appliances includes an archwire groove including at least one archwire stay configured to receive an archwire therein. Method 500 also includes aligning 504 an archwire with openings of said archwire grooves, sliding 506 the archwire laterally into said openings, retaining 508 the archwire in said at least one archwire stay, and adjusting 510 a tension of the archwire to a predetermined amount.

[0028] Described herein is an orthodontic appliance configured to be adhered to a surface of a tooth and configured to receive a plurality of differently sized archwires. In one embodiment, the orthodontic appliance includes a bonding surface configured to be adhered to the surface of the tooth, an opposing outside surface, a plurality of sidewalls extending between the bonding surface and the opposing outside surface, and an archwire groove extending from a sidewall of the plurality of sidewalls parallelly between the bonding surface and the opposing outside surface.
