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,
