A. Ligature
The archwire is held to each bracket with a ligature, which can be either a tiny elastic circle or a twisted wire.

B. Archwire
The archwire is tied to all of the brackets and creates force to move teeth into proper alignment.

C. Brackets
Brackets are connected to the bands, or directly bonded on the teeth, and hold the archwire in place.

D. Metal Band
The band is the cemented ring of metal which wraps around the tooth. These are usually placed only on the back molar teeth.

E. Elastic Hooks & Rubber Bands
Elastic hooks are used for the attachment of rubber bands, which help move teeth toward their final position.
