RESUMO
Resumo Os apinhamentos suaves a moderados na dentição mista podem ser tratados com expansão rápida da maxila (ERM) associada à expansão lenta do arco dentário inferior. A expansão lenta no arco inferior pode ser conduzida com uma alternativa de aparelho fixo e com parafuso. O objetivo deste artigo consiste em apresentar o protocolo laboratorial e clínico do expansor de Williams. Apresentou-se um caso clínico de uma paciente do sexo feminino, 9 anos de idade, com a face simétrica do Padrão I na dentadura mista, com apinhamento moderado dos incisivos inferiores e apinhamento suave no arco superior. O tratamento foi realizado com expansão superior e inferior. No arco superior, a ERM mediante o aparelho Hyrax foi realizada. No arco inferior, procedeu-se à expansão lenta com expansor de Williams. Obteve-se uma adequada oclusão com o alinhamento dos incisivos permanentes e uma melhora do corredor bucal no sorriso. O expansor de Williams representa uma alternativa para os casos que necessitam expansão lenta do arco dentário inferior, independendo da colaboração do paciente. Quando adequadamente construído, o expansor mostra-se confortável e efetivo. (AU)
ABSTRACT
Abstract Mild to moderate crowding in the mixed dentition can be treated with rapid maxillary expansion (RME) associated with dentoalveolar expansion of the mandibular arch. Dentoalveolar expansion of the mandibular arch can be conducted with an alternative fixed and screw appliance. The aim of this study is to present the laboratory and clinical protocol of the Williams expander. A clinical report of a female patient, 9 years old, with the symmetrical face in the mixed dentition, with moderate crowding of the lower incisors and mild crowding of the upper arch, was presented. The treatment was carried out with maxillary and mandibular expansion. In the maxillary arch, RME was performed using the Hyrax device. In the mandibular arch, dentoalveolar expansion was performed with a Williams expander. Adequate occlusion was obtained with the alignment of the permanent incisors and an improvement in the buccal corridor in the smile. The Williams expander represents an alternative for cases that require dentoalveolar mandibular expansion, regardless of patient cooperation. When properly constructed, the expander is comfortable and effective.(AU)
