What are thin wires used around brackets that hold arch wires in place?

Elastic ligatures are the thin wires used around brackets to hold arch wires in place. These ligatures are typically composed of rubber or elastic material and are essential in orthodontic treatment. They secure the arch wire— which connects the brackets— allowing for the controlled movement of teeth into their desired positions. Elastic ligatures come in various colors, providing both functional and aesthetic benefits in orthodontic care.

While orthodontic brackets are the small metal or ceramic devices bonded to the teeth to hold the arch wire in place, they do not serve the same purpose as elastic ligatures. Arch wires are the main components that guide the movement of the teeth but require ligatures to stay securely attached to the brackets. Bands, on the other hand, are metal rings that can be placed around the back teeth (molars) for anchoring braces but do not hold arch wires directly in place.
