occipital anchorage

occipital anchorage,

an orthodontic anchorage in which the resistance is borne by the top and back of the head and the force is transmitted to the teeth by means of the headgear and heavy elastics connected with attachment on the teeth.

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,

n a genus of Nematoda commonly known as
hookworm.
