Elastic Chain: Tiny rubber bands that are fit under the bracket to close spaces.
Archwire Loop: Occasionally used for closing space left by an extraction. Most archwires don't have loops.
Band: A thin ring of metal fitted around a tooth and cemented in placed. The band provides a way to attach the brackets to the tooth.
Bracket: The main, small attachment that holds the archwire in placed. Most often, a bracket is cemented directly onto the tooth's surface, eliminating the need for a band.
Headgear Tube (Rarely used in our office): Round, hollow attachment on the back of bands. The inner bow of the headgear fits into it.
Coil Spring: Fits between brackets and over archwires to open spaces between teeth.
Ligature Ties: Fine wire that is twisted under the archwire or around brackets.
Hook: Welded or removable arms used to attach elastics (rubber bands).
Elastics (Rubber Bands): Small rubber bands that hook between different points on the appliance to provide pressure to help move teeth.
