Parts of Braces

Appliance: Anything your orthodontist attaches to your teeth which moves your teeth or changes the shape of your jaw.

Archwire: The metal wire that acts as a track to guide your teeth along as they move. It is changed periodically throughout treatment as your teeth move to their new positions.

Band: A metal ring that is cemented to your tooth, going completely around it. Bands provide a way to attach brackets to your teeth.

Bond: The seal created by orthodontic cement that holds your appliances in place.

Bracket: A metal or ceramic part cemented (“bonded”) to your tooth that holds your archwire in place.

Coil Spring: A spring that fits between your brackets and over your archwire to open space between your teeth.

Elastic (Rubber Band): A small rubber band that is hooked between different points on your appliance to provide pressure to move your teeth to their new position.

Elastic Tie (O-tie): The tiny rubber band that fits around your bracket to hold the archwire in place. They come in a variety of colors. Patients can choose up to two colors at each visit.

Hook: A welded or removable arm to which elastics are attached.

Ligature: A thin wire that holds your archwire into your bracket.

Palatal Expander: A device that makes your upper jaw wider, creating space to aid eruption of permanent teeth into a more proper position.

Tie Wire: A fine wire that is twisted around your bracket to hold the archwire in place.
