Biometria dentária em pacientes padrão I braquifaciais e padrão face curta

Abstract

Introduction: Based on studies of the facial morphology of short face (PFC) patients, there is little evidence in the literature to characterize the static and functional occlusion as well as the dimensions of the arches in this pattern of facial growth (PFC). In this perspective, the study aims to compare the results obtained through the measurements in digitized models in brachyfacial I standard individuals and standard short face individuals; to evaluate the transverse and sagittal dimensions of the lower arches in both groups delineated through a trained and calibrated examiner; Observe and discuss whether the results obtained between the two groups outlined and the literature are statistically different or similar. Development: A cross-sectional study was carried out on pre-existing orthodontic documentation selected in the collection of the Specialization Course in Orthodontics of the University Center of the State of Pará (CESUPA). With 40 models of the volunteers of the sample being 20 standard brachyfacial I and 20 standard short face, were scanned optical 3D scanner and the scanned measurements performed through the nemocast® program, randomly and identified by groups and numbered, the measurements were fed into the excel program in The results were submitted to tables with mean, minimum, median and maximum values, standard deviations, the Kolmogorov-Smirnov test evaluated the normal distribution of all variables presented, the t test was performed 'Student and Person's correlation analysis. Conclusion: Based on the measurements performed on the transverse and sagittal dimensions of the lower arch of the two groups Standard I and the Short Face Pattern, the inter-canine, premolar and molar distances of standard Brachifacial I individuals were statistically significant between them , greater than the measurements of individuals Short Face Pattern. The arch length also showed differences in the clinically observed PI> PFC measurements in both groups of the samples. Thus, it was observed that the study showed statistically significant differences between the analyzed groups, corroborating the study of the facial pattern morphology between the patterns analyzed favoring the data specialist of extreme relevance for orthodontic treatment.
