anchorage,

n 1. the supporting base for orthodontic forces applied to stimulate tooth movement.
n 2. the area of application of the reciprocal forces generated when corrective forces are applied to teeth. Anchorage units may be one tooth or more or may include a portion of the neck or cranium.

anchorage bends,

n.pl bends placed in an orthodontic wire to enhance the resistance to the anterior displacement of teeth during orthodontic treatment; primarily used in the Tweed and Begg techniques.

anchorage, cervical,

n an extraoral anchorage based at the back of the neck.

anchorage, cranial,

n an extraoral anchorage based at the back of the skull.

anchorage, extraoral,

n in orthodontics, an orthodontic anchorage based outside the oral cavity. Dental attachments are typically linked to a wire bow or hooks extending between the lips and attached elastically to a cap, a strap around the neck, or another extraoral device.

anchorage, facial,

n an extraoral anchorage based on the face, usually the chin or forehead.

anchorage, intermaxillary,

n an anchorage based in the opposite jaw.

anchorage, intramaxillary,

n an anchorage based on teeth within the same jaw.

anchorage, intraoral,

n an anchorage based within the oral cavity (in-termaxillary, intramaxillary, or myofunctional).

anchorage, occipital,

n a cranial anchorage based in the occipital area.

anchorage, reciprocal,

n all anchorage is reciprocal; sometimes used to describe a force system in which the resistance units are similar.

anchorage, simple,

n the use of a tooth as a resistance unit without tipping control.

anchorage, stationary,
