Abstract
An orthodontic bracket for use with an archwire to impart corrective forces to a tooth, including a base portion attachable directly to a tooth, a bonding pad or a band and at least one tie wing extending from the base portion which includes gingival and occlusal tips and an archwire slot opening buccolingually and extending mesiodistally. The buccolingual profile of the bracket is rhomboidal, wherein the backside of the base portion and the front face are parallel and the occlusal and gingival sides are parallel, while an obtuse angle is defined between the outer face of the bracket and one of the occlusal or gingival sides depending upon the tooth on which the bracket is mounted and the torque desired.
