Tratamento ortopédico da má oclusão classe II, em criança com uso de aparelho extrabucal (AEB).

Abstract

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.
