Abstract
in English, Portuguese

Introduction: Anterior crossbite (AC) is defined as a reverse sagittal relationship between maxillary and mandibular incisors. According to an evidence-based orthodontic triage, the treatment need of AC is indicated if any occlusal interference is forcing the mandible towards a Class III growth pattern. Removable and fixed appliances have been suggested to correct AC.

Objective: The present report aims at presenting the benefits of an alternative therapy for the early treatment of anterior crossbite using clear aligners.

Methods: Two cases of anterior crossbite corrected using clear aligners in 8-years-old children are presented.

Results: In both cases, AC was successfully corrected within 5 months. At the end of the treatment, overjet and overbite were corrected. No major discomfort or speech impairment was noticed by the parents.

Conclusions: Due to the perceived shortcomings of alternative approaches, the use of clear aligners for correcting AC in mixed dentition should be considered as a comfortable and well tolerated appliance for young patients.

Introdução:: A mordida cruzada anterior (MCA) é definida como uma relação sagital reversa entre os incisivos superiores e inferiores. De acordo com a evidência científica, o tratamento da MCA é indicado em casos em que a interferência oclusal favorece o crescimento mandibular em direção a um padrão de Classe III. A literatura descreve diversos aparelhos removíveis e fixos para a correção dessa má oclusão.

Objetivo:: A presente série de casos tem como objetivo apresentar os benefícios de uma terapia alternativa para o tratamento precoce da MCA por meio do uso de alinhadores transparentes.

Métodos:: Apresentação de dois casos de MCA tratados com alinhadores transparentes em crianças de 8 anos de idade.

Resultados:: Em ambos os casos, a MCA foi corrigida com sucesso em um período de 5 meses. Ao fim do tratamento, obteve-se sobressaliência e sobremordida ideais. Segundo o relato dos pais, nenhum grande desconforto ou comprometimento na fala foi observado.

Conclusões:: Tendo em vista os problemas associados a algumas abordagens alternativas, o uso de alinhadores transparentes para correção da MCA durante a dentição mista pode ser considerado confortável e bem tolerado por pacientes jovens.
