Abstract
An orthodontic bracket assembly may include a mounting plate configured to be coupled to a tooth. A bracket member may include a single tie-wing having a superior tie-wing portion, an inferior tie-wing portion, and a slot defined between planar side walls of the superior and inferior tie-wing portions. Each of the superior and inferior tie-wing portions may include a curved surface extending at a mesial end of the tie-wing portion and a distal end of the tie-wing portion.
Claims17
An orthodontic bracket assembly, comprising:
- a mounting plate configured to be coupled to a tooth;
- and
- a bracket member including a single tie-wing having a superior tie-wing portion extending in a superior direction, an inferior tie-wing portion extending in an inferior direction opposite to the superior direction, and a slot defined between planar side walls of the superior and inferior tie-wing portions and configured to receive a wire,
- wherein each of the superior and inferior tie-wing portions includes a curved surface extending in a mesial-distal direction at a mesial end of the tie-wing portion and a curved surface extending in the mesial-distal direction at a distal end of the tie-wing portion and defining an entrance of the slot,
- wherein a superior parabolic surface of the superior tie-wing portion extends from the respective planar side wall in a superior direction, and
- wherein an inferior parabolic surface of the inferior tie-wing portion extends from the respective planar side wall in an inferior direction.

An orthodontic bracket assembly, comprising:
- a mounting plate configured to be coupled with a tooth, the mounting plate including a plurality of protrusions and a plurality of grooves positioned between adjacent protrusions;
- a support member rotatably coupled to the mounting plate and including a pair of flexible tabs, wherein each tab is configured to be selectively received in a groove, and
- a bracket member having a slot configured to receive a wire, and the slot is configured to move between a plurality of discrete angular positions relative to the mounting plate by selectively positioning each of the pair of tabs in opposing grooves,
- wherein the bracket member includes a single tie-wing having a superior tie-wing portion extending in a superior direction, an inferior tie-wing portion extending in an inferior direction opposite to the superior direction,
- wherein the slot is defined between planar side walls of the superior and inferior tie-wing portions,
- wherein each of the superior and inferior tie-wing portions includes a curved surface extending at a mesial end of the tie-wing portion and a distal end of the tie-wing portion and defining an entrance of the slot,
- wherein a superior parabolic surface of the superior tie-wing portion extends from the respective planar side wall in a superior direction, and
- wherein an inferior parabolic surface of the inferior tie-wing portion extends from the respective planar side wall in an inferior direction.
