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