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 />
