Resumo: | INTRODUCTION: This study evaluated changes in the smile characteristics of patients with maxillary constriction submitted to rapid maxillary expansion (RME). METHODS: The sample consisted of 81 extraoral photographs of maximum smile of 27 patients with mean age of 10 years, before expansion and 3 and 6 months after fixation of the expanding screw. The photographs were analyzed on the software Cef X 2001, with achievement of the following measurements: Transverse smile area, buccal corridors, exposure of maxillary incisors, gingival exposure of maxillary incisors, smile height, upper and lower lip thickness, smile symmetry and smile arch. Statistical analysis was performed by analysis of variance (ANOVA), at a significance level of 5%. RESULTS: RME promoted statistically significant increase in the transverse smile dimension and exposure of maxillary central and lateral incisors; maintenance of right and left side smile symmetry and of the lack of parallelism between the curvature of the maxillary incisal edges and lower lip border. CONCLUSIONS: RME was beneficial for the smile esthetics with the increase of the transverse smile dimension and exposure of maxillary central and lateral incisors. |

MÉTODOS: a amostra consistiu de 81 fotografias extrabucais do sorriso máximo de 27 pacientes, com idade média de 10 anos, antes da expansão e aos três e seis meses após a fixação do parafuso expansor. As análises das fotografias foram realizadas por meio do programa Cef X 2001, e as seguintes medidas foram analisadas: dimensão transversal do sorriso, corredores bucais, quantidade de exposição dos incisivos superiores, exposição gengival dos incisivos superiores, altura do sorriso, espessuras dos lábios superior e inferior, simetria e arco do sorriso. As alterações no sorriso durante as diferentes fases foram avaliadas por meio da análise de variância (ANOVA), seguida pelo teste de comparações múltiplas de Bonferroni, com nível de significância de 5%. RESULTADOS: a ERM promoveu aumento estatisticamente significativo da dimensão transversal do sorriso e da quantidade de exposição dos incisivos centrais e laterais superiores; manutenção da simetria entre os lados direito e esquerdo e da falta de paralelismo entre a curvatura das bordas dos incisivos superiores e a do lábio inferior. CONCLUSÃO: a ERM beneficiou a estética do sorriso com o aumento da dimensão transversal do sorriso e da quantidade de exposição dos incisivos centrais e laterais superiores.Methodist University of São PauloSacred Heart UniversityUNIFESPUSP FOUNIFESPSciELODental Press InternationalMethodist University of São PauloSacred Heart UniversityUniversidade Federal de São Paulo (UNIFESP)Universidade de São Paulo (USP)Carvalho, Ana Paula Morales Cobra DeGoldenberg, Fernanda CavicchioliAngelieri, FernandaSiqueira, Danilo FurquimBommarito, Silvana [UNIFESP]Scanavini, Marco AntonioKanashiro, Lylian Kazumi2015-06-14T13:44:58Z2015-06-14T13:44:58Z2012-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion94-101application/pdfhttp://dx.doi.org/10.1590/S2176-94512012000500014Dental Press Journal of Orthodontics.
