Abstract: An orthodontic ligature for securing an orthodontic archwire to an orthodontic bracket. The orthodontic ligature is formed of a resilient band which forms a flap. The flap forms a grip portion. The resilient band defines a non-circular hole having a major dimension along the direction in which the grip portion extends. The invention provides an easy to use orthodontic ligature which further is maximized in durability.
