Tratamento de má oclusão de Classe III subdivisão com mordida cruzada posterior unilateral através da técnica multiloop edgewise archwire (MEAW) – relato de caso

Abstract

The aim of this study was to report a clinical case of treatment of Class III subdivision malocclusion with unilateral posterior crossbite using the Multiloop Edgewise Archwire (MEAW) technique. A 19-year-old male patient reported mandibular prognathism as the main complaint. He had Angle Class III malocclusion, unilateral posterior crossbite on the right side, top bite in the anterior region, non-coincident midlines and facial asymmetry. Due to the patients refusal of surgical treatment, dentoalveolar orthodontic compensation was proposed. The MEAW technique associated with 3/16” intermaxillary elastics were used. At the end of the treatment, a Class I occlusal relationship between canines and molars, correction of the unilateral posterior crossbite and coincidence between the midlines was obtained. The MEAW technique was effective in correcting Class III subdivision malocclusion and unilateral posterior crossbite.
