Orthodontic Dictionary: Orthodontics Definitions

Orthodontics Definitions | St. Louis Orthodontic Group

At St. Louis Orthodontic Group, we understand the terminology can be a little daunting when it comes to orthodontics definitions. To help provide you with a bit more clarity, we have put together this list of some of the more common orthodontics definitions.

Orthodontics Definitions: Components of Braces

  • Appliance – Any device used by your orthodontist that attaches to your teeth and moves them or changes the shape of your jaw
  • Archwire – The main wire that guides the movement of your teeth. It is exchanged intermittently throughout your treatment as your teeth reposition
  • Band – A metal ring that encompasses the tooth and allows the brackets a way to be attached to your teeth
  • Bond – Seal of the orthodontic cement that adheres appliances in place
  • Bracket – The metal or ceramic piece bonded to your tooth meant to hold the archwire in place
  • Coil Spring – A spring placed between your brackets and over the archwire meant to open space between your teeth
  • Colored Ties– Colored ties are rubber rings (not to be confused with ‘rubberbands’ or ‘elastics’). They come in many fun colors and fasten archwires to brackets.
  • Elastic/Rubber Band – Small rubber band that hooks between different points on your appliances and applies pressure to guide your teeth to their desired position
  • Elastic Tie – The tiny rubber band that wraps around the brackets to keep the archwire in position
  • Headgear – An appliance that attaches to the patient’s head via neck straps. The device is meant to address severe bite problems
  • Hook – A small, metal arm to which elastics are attached
  • Ligature – A thin wire that positions your archwire into your brackets
  • Lip Bumper – An archwire with molded plastic that holds back lower jaw molars to allow more space for other teeth
  • Mouthguard – A shield for teeth and gums worn to protect the mouth during sporting activities
  • Palatial Expander – A device that widens the upper jaw
  • Retainer – A device worn after braces meant to hold teeth in place
  • Separator/Spacer – A small rubber ring that provides a space between teeth before bands can be attached
  • Tie Wire – A thin wire that is twisted around the bracket to hold the archwire in place
  • Wax – Provided to aid in mitigating cheek and lip irritation from braces
