Orthodontic Ligatures are tiny rubber bands that tie the brackets and the wires together. They are a much-needed part of your orthodontic system because they help to evenly distribute the occlusal forces used to straighten your teeth. Without them, only part of the tension of the wire can actively align your teeth. Their primary task is to firmly hold the archwire in the slotted position on each bracket. Moreover, depending upon how they are used and how they are attached to the teeth, these bands can additionally play a role in guiding tooth structures into the desired direction.
