Abstract<br />

Extraoral anchorage still is one of the most<br />

used and recommended procedures in the<br />

treatment of Class II, division 1 malocclusion,<br />

which is characterized by maxillar and/or dentoalveolar<br />

protrusion. However, only the<br />

appropriated use of extraoral orthopedic forces<br />

can determine satisfactory clinical results.<br />

The selection of the pull direction (high,<br />

medium or low pull) is directly related to craniofacial<br />

growth pattern and muscle pattern.<br />

Other factors to be considered are the growth<br />

stage and the face and teeth development, the<br />

forces intensity to be applied and the patient<br />

cooperation.<br />

All types of extraoral pull are beneficial to<br />

the patient, since correctly indicated and used,<br />

avoiding in many instances dental extraction.<br />

The purpose of this study is to address<br />

the main indications and effects of the occipital<br />

pull headgear (I.H.G.) as well as to<br />

present a clinical case treated with this<br />

procedure associated to the nonextraction<br />

fixed orthodontic therapy.<br />

Uniterms: Orthodontics; Class II,<br />

division 1 malocclusion; Extraoral<br />

anchorage.<br />
