Respiração oral e má oclusão em desenvolvimento: possibilidades terapêuticas

Abstract

The aim of this study was to verify, through speech pathologic, orthodontic and cephalometric evaluation, the effect of Pre Orthodontic restricted treatment and the associated Miofunctional Therapy in mouth breathing children with malocclusion in development. The sample of this study was formed by 5 children, both sexes, with age range from 8 to 12 years old. From initial estimations the subjects were separated into two groups, G1 (with three children) and G2 (with two children), receiving, respectively, Trainer Pre-Orthodontics associated with Miofunctional Therapy treatment and restricted Trainer Pre-Orthodontics treatment. After the average period of one year the children were reexamined. The obtained results leaded to the conclusions that there were important changes in the muscular structures and functions of stomatognathic system (tongue and lips posture, deglutition, masticating, breathing and speech) when speech pathologic and pre orthodontic intervention were applied at the same time; that the modifications in osseous and muscular structures were higher when received speech pathologic and pre orthodontic intervention simultaneously; that the modifications of dental relations between maxilla and mandible were higher from the osseous relation with these structures; that the pre orthodontic treatment enable a better dental position, mandible position and miofunctional training; and finally that the progress obtained with exclusive pre orthodontic treatment, in what concerns the dental structures, can be maximized with association with Miotherapy treatment.
