A thin metal ring, usually stainless steel, which serves to secure orthodontic attachments to a tooth. The band, with orthodontic attachments welded or soldered to it, is closely adapted to fit the contours of the tooth and then cemented into place.

An orthodontic attachment that is secured to a tooth (either by bonding or banding) for the purpose of engaging an archwire. Brackets can be fabricated from metal, ceramic or plastic.

ceramic brackets
Crystalline, alumina, tooth-shade or clear synthetic sapphire brackets that are aesthetically more attractive than conventional metal attachments.

Dental malalignment caused by inadequate space for the teeth.

The removal of cemented orthodontic bands.

elastics (rubber bands)
Used to move teeth in prescribed direction (commonly connected to molar band and upper ball hook). Found in numerous colors for better appearance.

The tissue that surrounds the teeth, consisting of a fibrous tissue that is continuous with the periodontal ligament and mucosal covering.

Generic term for extraoral traction (attached around the back side of the head) for growth modification, tooth movement and anchorage.

Herbst appliance
