ABSTRACT:
An orthodontic bracket having a transverse slot for receiving a conventional orthodontic arch wire, and which is constructed so that a resilient tie ligature used to retain the arch wire in place in the slot is supported on the bracket in a doubled-over configuration. This permits the arch wire to be more firmly and positively held in the transverse slot of the bracket, and it permits a reduction in size of the bracket because it eliminates the need for the gingival portion of the peripheral groove around the bracket which is used in the prior art brackets to retain the ligature.
