Angle Class II malocclusion treated with extraction of permanent teeth.

Angle Class II malocclusion associated with anterior open bite in adult patients demands a carefully elaborated orthodontic planning, aiming at restoring not only harmonious dental and facial esthetics, but also a balanced masticatory function. Orthognathic surgery or permanent teeth extraction are often the choice of treatment, therefore, treatment decision is related to all dental, skeletal and functional aspects. The present report discusses orthodontic compensation carried out by means of upper premolar extraction performed to correct the Class II canine relationship and, consequently, the anterior open bite, accepting that the upper incisors be retroclined. This clinical case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as part of the requirements for obtaining the BBO Certification.

A má oclusão Classe II de Angle associada à mordida aberta anterior, em pacientes adultos, envolve um planejamento ortodôntico bem elaborado e cuidadoso, tendo como objetivo principal devolver a estética facial e dentária harmoniosa, e uma função mastigatória equilibrada. O tratamento, muitas vezes, está no limite para cirurgia ortognática ou para extrações de dentes permanentes, fazendo com que a decisão esteja ligada a todos os aspectos dentários, esqueléticos e funcionais. O presente relato mostra a compensação ortodôntica por meio de extrações de pré-molares superiores, a fim de corrigir a relação de Classe II dos caninos e, consequentemente, a mordida aberta anterior, aceitando que os incisivos superiores estejam retroinclinados. Esse caso clínico foi apresentado à diretoria do Board Brasileiro de Ortodontia e Ortopedia Facial (BBO) como parte dos requisitos para a obtenção do título de Diplomado pelo BBO.
