| FH+ | Family history of hypertension |
| simple anchorage | Anchorage in which the resistance to the movement of one or more teeth comes solely from resistance to tipping movement of the anchorage unit. (05 Mar 2000) |
|---|---|
| stationary anchorage | Anchorage in which the resistance to the movement of one or more teeth comes from the resistance to bodily movement of the anchorage unit; a questionable concept since the selected teeth remain only relatively stable. (05 Mar 2000) |
| intermaxillary anchorage | Anchorage in which the units in one jaw are used to effect tooth movement in the other jaw. (05 Mar 2000) |
| intramaxillary anchorage | Anchorage in which the resistance units are all situated within the same jaw. (05 Mar 2000) |
| intraoral anchorage | Anchorage in which the resistance units are all located within the oral cavity. (05 Mar 2000) |
| occipital anchorage | Anchorage in which the top and back of the head are used for resistance by means of a headgear. (05 Mar 2000) |
| extraoral anchorage | Anchorage in which the resistance unit is outside the oral cavity; e.g., cranial, occipital, or cervical anchorage. (05 Mar 2000) |
