ABSTRACT:
An orthodontic bracket is provided for use with an arch wire. The bracket includes a bracket main member having upper, middle and lower portions. The middle portion includes a slot formed therein for receiving the arch wire. Wings are formed on the upper and lower portions of the bracket main member for enabling a ligature to be tied therewith to secure the arch wire in place in the slot. Engaging portions are formed on the wings for enabling the ligature to be held in a tied state on the wings such that the ligature avoids pressured contact with the arch wire, thereby allowing the bracket to move smoothly along the arch wire during orthodontic treatment requiring such movement.
