Resumo:
Among the malocclusion’s classification, the Angle’s class II is characterized by a
dentoalveolar, maxillomandibular and anteroposterior discrepancy, and may be
caused by a mandibular retrusion, a maxillary protrusion, or a combination of both. The
choice of the treatment used is directly related to the patient's facial and muscular
growth, the stage of development of the face and teeth, intensity of forces to be applied
and cooperation of the patient. All the types of extraoral traction bring benefits to the
patient, when they are indicated and used correctly, and may sometimes avoid the
tooth extraction. The present study aimed to report a clinical case of a female patient,
with 8 years old, in the skeletal growth stage and with Angle’s class II malocclusion.
This study was categorized as a case report and the patient was monitored at the
Dental School of the Federal University of Campina Grande. The treatment was
performed with the Extraoral Appliance (AEB) of cervical traction, using the clinical
protocol of 14 hours daily, strength of 500g, during one year. After this period, it was
used another year as retainer applying a force of 200g. The correction of skeletal
malocclusion could be observed through clinical and cephalometric exams, after the
finalization of the treatment. The AEB used at early ages, taking advantage of the
growth and development phase, allows better orthopedic effects and, therefore, better
basal relation and facial profile, creating stability to the results, making easy or even
shortening the subsequent fixed orthodontic treatment.
