Orthodontic mirror image brackets to removably receive the end portions of lingual arch wires |
摘要 |
An orthodontic bracket comprises a body having first and second ends, a first vertical sidewall for attachment to a molar band, and a second sidewall extending arcuate and upwardly away from a lower portion of the first sidewall. A contoured slot extends between the ends and downwardly from an upper portion of the first sidewall for defining an upper and a lower channel, and the lower channel permits the second sidewall to flex outwardly relative to the first sidewall. The upper channel includes a lower arcuate surface upon which an orthodontic wire seats. The second sidewall includes a pawl overlying the upper channel and extending substantially the length thereof for engaging and maintaining an orthodontic wire in the upper channel and against the lower arcuate surface.
