Resumo
Esta pesquisa tem como objetivo principal avaliar a aplicabilidade do Diagrama de Andrade em indivíduos de oclusão normal como método auxiliar no diagnóstico e planejamento ortodônticos. Este trabalho complementa estudos anteriores realizados em amostras de indivíduos de má oclusão de Classe I e Classe II, de Angle, onde o diagrama de Andrade se mostrou eficiente auxiliar para o diagnóstico e planejamento ortodôntico, servindo de parâmetro para quantificar a expansão necessária para os arcos dentários, e também, indicando a necessidade ou não de exodontia de premolares. Neste trabalho foram selecionadas 20 documentações de indivíduos, leucodermas, com dentição permanente e com oclusão normal, que nunca foram submetidos a tratamento ortodôntico, procurando respeitar as seis chaves para a oclusão normal, preconizada por Andrews (1972), dos sexos masculino e feminino. Os diagramas individualizados foram obtidos por meio das telerradiografias cefalométricas laterais dos indivíduos, onde depois de realizado os traçados e as medidas da cefalometria e dos modelos dos arcos dentários inferiores foram construídos os diagramas e, posteriormente, foram sobrepostos às imagens digitalizadas dos modelos em gesso. As variáveis obtidas por meio das medições, realizadas com paquímetro digital, sobre os modelos escaneados foram comparadas e analisadas estatisticamente pelo test t de Student (p < 0,05), com uma amostra de má oclusão de Classe I de Angle. Houve diferença significativa entre os grupos para a medida do somatório mésio-distal de incisivos e caninos inferiores com médias de 35,88mm para o grupo normal e 37,08mm para o de Classe I, nas diferenças entre o diagrama de Andrade e as imagens digitalizadas dos modelos inferiores os grupos diferiram significantemente...
This research aims to evaluate the applicability of the Andrade´s diagram in patients with normal occlusion, and assist in diagnosis and orthodontic planning. This work complements previous studies in samples of individuals Class I and Class II malocclusion of Angle, where the Andrade´s diagram proved effective to orthodontic diagnosis and treatment planning, serving as a parameter to quantify the expansion needed for the dental arches and indicating the need or not the extraction of premolars. In this work, the documentations from 20 individuals were selected with permanent dentition and with normal occlusion, which were never subjected to orthodontic treatment, respecting the six keys to normal occlusion, as recommended by Andrews (1972), in sample from male and female. The individual diagrams were obtained from the lateral cephalometric radiographs of the individuals, where after performing the cephalometric traces, cephalometric measurements and the lower dental arches model measurements the diagrams were constructed and then be overlaid on scanned plaster casts. The variables obtained by means of measurements made with digital calipers on scanned models were compared and statistically analyzed by Student's t test (p <0.05), with a sample of Class I malocclusion Angle. There were significant differences between groups for the measure of the sum of mesio-distal lower incisors and canines with averages of 35.88 mm for the normal group and 37.08 mm for Class I malocclusion, the differences between the Andrade´s diagram and the digital images of the lower models differed significantly, both in the region intercanine (3-3), as well as the region intermolar (6-6), with averages -0.04 mm and 0.74 mm, respectively, for normal occlusion and Class I in the region of canines and -0.28 mm and 1.43 mm, respectively...
