One of the most crucial factors in the effectiveness of clinical orthodontics is anchorage control. There are many anchorage devices available to obtain the proper anchorage. The most effective tools-extraoral anchorages like headgear or facemasks-have the drawback that their success depends on patient compliance. Elastics used between the teeth suffer from the same drawback. Although patient cooperation is not necessary for intraoral anchorages such as the transpalatal arch, lingual arch, holding arch, and others, it is impossible to guarantee absolute anchorage.
