Introduction: Orthodontics has clinical benefits, however, the psychosocial outcomes are not well understood. These soft benefits are often classified as aesthetic, functional, and psychosocial, however, there is limited work understanding these outcomes as reported directly from the patient. By better understanding the patient’s perspectives, we can continually refine our clinical model to be patient-centric and more appropriately manage the patient’s expectations and experiences. Materials and Methods: This is a cross-sectional qualitative study of 20 parents of 24 children ages 8-11 years. Participants were remotely interviewed using a semi-structured chronologically based line of questioning to elucidate their perceived outcomes of early orthodontic treatment or phase one. A content thematic analysis using a framework approach was used to analyze the resulting data. Results: The thematic analysis uncovered four major themes and associated subthemes as follows (1) dental health including functional changes, aesthetic improvement, and improved cleansability; (2) opportunity cost: meaning harnessing growth for lasting change, avoidance of future orthodontic treatment, avoidance of future dental treatment, and supervision of growth; (3) social outcomes: encompassing external perception and acceptance, self-perception, parental perception, and reduced dental anxiety; and (4) behavioral changes: including the correction of bad habits, development of good oral hygiene, and an increase in responsibility of the patient. Conclusions:This study highlights the depth of psychosocial benefit perceived by patients undergoing early orthodontic treatment, with the main outcome being functional improvement, followed by an advantage to treatment at a young age, and an improvement in aesthetics. Patients did not recognize an increase in self-perception which is contrary to outcomes previously found in other age groups.

O propósito do estudo foi avaliar um novo procedimento para o tratamento precoce da Classe II Subdivisão com envolvimento mandibular, método proposto por Sakima 85 em 2003. A amostra foi dividida em: Grupo 1 - Portadores de má oclusão Classe II Subdivisão com mordida cruzada posterior unilateral (D) ou (E) e Grupo 2 - Portadores de má oclusão Classe II Subdivisão sem cruzamento. Todos os indivíduos foram submetidos a tratamento ortodôntico de interceptação para correção da subdivisão, sendo que o Grupo 1 teve procedimento prévio para descruzamento da mordida cruzada posterior unilateral (MCPU). A avaliação dos resultados foi realizada mediante tomada de radiografias extra-orais Submento-vertex, os cefalogramas foram traçados e os dados compilados para análise em computador. Os traçados cefalométricos obtidos das imagens radiográficas da Submento-vertex (SMV) foram digitalizados no programa Radiocef. Os dados analisados, submetidos à metodologia estatística e os resultados discutidos. O método estatístico empregado, além da utilização da média e desvio padrão, contou com o Teste t de Student, Teste F de Snedecor e probabilidade p, utilizou-se também o teste não paramétrico de Mann-Whitney-Wilcoxon, os dados estatísticos foram utilizados para avaliar os resultados do tratamento ortodôntico realizado. Após a discussão dos resultados, concluiu-se que: 1)Houve presença de rotação mandibular significante para ambos os grupos estudados quando relacionada maxila e mandíbula; 2) A evolução dos grupos estudados foi semelhante tanto clínica como cefalométrica; 3) Os movimentos dentários constatados melhoram o... . / The purpose of this study was to evaluate a new approach to the early orthodontic treatment of Class II, division 1, subdivision, in the mixed dentition and determined the utility of approach. The sample consisted of 23 subjects divided in two groups (group 1 and group 2). The average was 9.3 years considered in both groups. Measurements were obtained with the use of Submento-vertex Cephalometric Radiographs. The Submento-vertex Radiographs symmetry was assessed by measuring the differences in the spatial positions of dental and Skeletal landmarks between right and left side, determined asymmetric (A) and normal (N) sides. The Angle's 2 Class II subdivision was evaluated in the mixed dentition. Statistic method was based on the skewness statistics, the distributions were normal, allowing means and standard deviations to be used to describe central tendencies and dispersion. We also used the Student t test, the Snedecor p test and Mann-Whitney-Wilcoxon tests were used to statistically comparation.The results showed lower jaw replacement and dento-alveolar displacement in order to correct this malocclusion. The conclusions about the present study were: 1) There was significant mandibular rotation from the asymmetric side to the symmetric side in the two groups when maxilar and mandibular relation was investigated; 2) The two groups evolution was clinical and cephalometrical similar; 3) The teeth movements provide evidence to better relation of the occlusion; 4) The midline line of the teeth has a clinically consistent to normalization and this can better investigated with other evaluation methods.
