Malocclusion - This means a "bad bite" such as crowded teeth, spaced teeth, protrusion of the upper or the lower teeth, crossbite, etc.
Impressions or molds - An imprint of your teeth made by placing a tray of soft Jello-like material in your mouth. The doctor then pours plaster into the impression to make a stone model of your teeth.
Crossbite - A bite problem where the upper front teeth may lie behind the lower front teeth. This condition can also occur in the back of the mouth.
Palate Widening Appliance - A brace placed in the roof of your mouth to expand the upper dental arch.
Bracket - The small attachments applied to your teeth. The brackets are the parts of your braces to which the doctor or assistant attaches the archwire.
Archwire - This is the part of your braces which actually move your teeth. The archwire is attached to the brackets by small elastic donuts or ligature tie wires.
Headgear - Often called a "Night Brace". The headgear is used to correct a protrusion of the upper or lower jaw. Headgear can also be used to hold the teeth against the pull of rubber bands used to correct a bite problem.
Retainer - A plastic appliance usually with a singular wire across your front teeth. This holds the teeth in their new corrected positions until the bone and tissue readapt.
