Parts of Braces

Appliance
Anything your orthodontist attaches to your teeth that moves your teeth or changes the shape of your jaw.
Archwire
The metal wire that acts as a track to guide your teeth as they move. It is changed periodically throughout treatment as your teeth move to new positions.
Band
A metal ring that is cemented to your tooth that goes completely around it. Bands provide a way to attach brackets, tubes, or palatal expanders 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. It is the "handle" for each tooth.
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 a new position.
Elastic Tie (O-Ring)
The tiny rubber band that fits around your bracket to hold the archwire in place. They come in a variety of colors.
Headgear
Traditional Headgears use an external wire apparatus known as a facebow to guide the growth of your face and jaw gently by moving your teeth into proper position. The force is applied to the facebow by a spring-loaded neck strap or head strap. The straps have a safety release that disconnects if the facebow is pulled or snagged. Protraction headgears (for underbites) are attached to the teeth with rubber bands.
Headgear Tube
A round, hollow attachment on your back bands. The inner bow of your headgear fits into it.
Hook
A welded extention or twisted wire on the bracket or removable arm to which elastics are attached. 
Ligature
A thin wire that holds your archwire into your bracket.
Lip Bumper
A lip bumper is an archwire attached to a molded piece of plastic. The lip bumper holds back the molars on your lower jaw to provide more space for your other teeth.
Mouthguard
A device that protects your mouth from injury when you participate in sports or rigorous activities.
Palatal Expander
A device that makes your upper jaw wider.
Retainer
An appliance that is worn after your braces are removed; the retainer attaches to your upper and/or lower teeth to hold them in place. Some retainers are removable, while others are bonded to the tongue side of several teeth.
Separator or Spacer
A small rubber ring that creates space between your teeth before the bands are attached.
Tie Wire
A fine wire that is twisted around your bracket to hold the archwire in place. Also known as a ligature tie.
Wax
Wax is used to stop your braces from irritating your lips.

Orthodontic Procedures

Banding
The process of fitting and cementing orthodontic bands (metal rings) on your teeth.

Cephalometric X-ray
An X-ray of your head that shows the relative positions and growth of the face, jaws, and teeth.
Consultation
A meeting with your orthodontist to discuss a treatment plan. Also known as a treatment presentation.

Digital Scan
The process of making a 3-Dimensional computer model of your teeth using a "wand" that takes multiple pictures of your teeth and "stitches" them together.
Impressions
A model of your mouth made by placing a tray filled with soft material over your teeth. The soft material hardens into a footprint of your teeth. Your orthodontist will use these impressions to prepare your treatment plan or fabricate an appliance. 
Invisalign®
An alternative to traditional braces, Invisalign straightens your teeth with a series of clear, custom-molded aligners. Invisalign can correct some, but not all, orthodontic problems. Invisalign® is a name brand for aligners, like Kleenex® is a name brand for tissues.

Panoramic X-ray
