What are orthodontic ligatures and why are they used?

It is easy to feel overwhelmed and that you shouldn’t ask questions, however it is important that you understand what is happening and part of your orthodontist role is to explain the process so that you can properly consent to the treatment.

This blog will be focussing on ligatures, what they are and why they are used.

Orthodontic ligatures are tiny rubber bands that tie the brackets and wires together. They are a much needed part of your orthodontic treatment because they help to evenly distribute the occlusal forces (the force exerted on opposing teeth when your upper and lower teeth meet together) to straighten your teeth.

Orthodontic ligatures are usually hooked up to the brackets and tie the wire to the brackets themselves but can be placed anywhere where extra pressure is needed, or where the wire needs to be tied down to affect the entire row of teeth.

Orthodontic ligatures can be colourful or transparent. Some patients prefer to have the invisible look however some like to have a more fun look and to draw attention to their braces.

Ligatures are not always elastic they can also be surgical steel power chains. These are large, flat linked chains that are attached to certain teeth and are only necessary in certain cases, but where necessary it would be extremely difficult to achieve the desired movement without them. For example, a patient may have two teeth overlapping which may not straighten out with elastics but instead require a flat linked chain attached to the teeth in order to progress movement.

If you are undergoing orthodontic treatment, please do not hesitate to ask your orthodontist what they are going to be doing during your appointments regardless of whether you are having treatment under the NHS or privately. It is your teeth and your treatment plan so do not be afraid to ask questions! If you are concerned that you may have received substandard orthodontic treatment, please contact us.
