RESUMO

The purpose of this study was to evaluate horizontal and vertical smile characteristics; smile symmetry and smile arch of patients with maxillary atresy submitted to rapid palatal expansion. The sample was 81 extra oral photographs of maximum smile of 27 patients with medium age of 10 years. Photographs of maximum smile were taken at: inicial time or before expansion; 3 months after rapid palatal expansion ending and 6 months after rapid palatal expansion ending. The computer program CEFX 2001 Cefalometria Computadorizada CDT was used for photographies calibration and analysis. The reference points and measurements were chosen according to literature review about smile analysis. Statistical analysis was performed by using ANOVA variance analysis, at level of 5% of significance. Rapid palatal expansion resulted on estatistically significant increase of smile transversal area and upper central and lateral incisors display; maintenance of right and left side smile symmetry and absence of parallelism of curvature of the upper incisal edges and border of lower lip (smile arch).(AU)
