Abstract

Abstract: Introduction: This cross-sectional study aimed to associate the normative cephalometric results of mandibular retrognathism treatment with patient perception on the esthetic improvement of facial profile.

Objective: this cross-sectional study aimed to associate the normative cephalometric results of mandibular retrognathism treatment with patient perception on the esthetic improvement of facial profile.

Material and method: The normative cephalometric results were obtained from lateral cephalometric radiographs of a sample of 24 Class II malocclusion patients in the pubertal growth spurt. Such patients were treated with a mandibular advancement device and evaluated by comparing pre- and post-treatment variables. The same radiographs were used to produce standardized black silhouettes that were randomly arranged. Patients were instructed to choose their preferred profile and indicate the changes perceived using a 7-point Likert scale. The data were compared with cephalometric results using a mixed-model methodology for time-repeated measures, Student’s t-test, and t-test for heterogeneous variances, at 5% significance level.

Result: A rate of 75% of patients preferred post-treatment silhouettes and changes were perceived regardless of the choice of either pre- or post-treatment profile. There was no significant difference between the cephalometric variables of the tracings that produced the silhouettes considered better or worse after the evaluation.

Conclusion: There was no association between the cephalometric results after treatment and the perception of esthetic improvement by patients treated for mandibular retrognathia.

Resumo

Resumo: Introdução: Este estudo transversal buscou associar resultados cefalométricos normativos do tratamento do retrognatismo mandibular com melhora estética do perfil facial na percepção do paciente.

Objetivo: este estudo transversal buscou associar resultados cefalométricos normativos do tratamento do retrognatismo mandibular com melhora estética do perfil facial na percepção do paciente.

Material e método: Os resultados cefalométricos normativos obtidos em radiografias cefalométricas laterais de uma amostra de 24 pacientes com maloclusão de Classe II em fase de crescimento tratados com aparelho de avanço mandibular, foram avaliados comparando-se as grandezas pré e pós-tratamento. As mesmas radiografias foram utilizadas para gerar silhuetas negras padronizadas que foram dispostas aleatoriamente. Os pacientes foram instruídos a escolher seu perfil preferido e indicar quanta mudança foi percebida por meio de uma escala de Likert de 7 pontos. Os dados foram comparados com resultados cefalométricos aplicando-se metodologia de modelos mistos para medidas repetidas no tempo, teste t de student e teste t para variâncias heterogêneas, com nível de significância de 5%.

Resultado: 75% dos pacientes escolheram silhuetas pós-tratamento e a mudança foi percebida independentemente da escolha por pré ou pós-tratamento. Não houve diferença significativa entre as variáveis ​​cefalométricas dos traçados que deram origem às silhuetas consideradas melhores e piores após a avaliação.

Conclusão: Não houve associação entre os resultados cefalométricos pós-tratamento e a percepção da melhora estética por pacientes ortodônticos.
