ABSTRACT:
An improved orthodontic ligature for securing an arch wire to an orthodontic bracket has a stretchable ring member and an outwardly-extending grip extension integrally connected to the ring member. The ligature may be gripped at the grip extension using a pinching or clamping tool, facilitating installation of the ligature. An improved method of installing the ligature is also provided whereby the ring member is stretched to clear over tie wings of the bracket by pulling on the grip extension.
