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.

Orthodontic bracket with rhomboidal profile

An orthodontic appliance to be used in a straight-wire technique setup as an auxiliary for applying closing forces between spaced teeth, wherein the appliance is mounted on a bracket attached to a band or pad. The appliance includes a base attachable to the bracket and an arm extending from the base and terminating in a hook for the attachment thereto of a force transmission member, such as an elastic. The appliance is attached to the bracket so that it is removable from the bracket after the use of the appliance has been completed and while the bracket remains mounted on a tooth.
