The previous knowledge of the teeth position on the dental arches is one of the most important subjects in Orthodontics. When an orthodontic treatment is planned, dental arches must be evaluated to enhance the stability prognosis. According to the articles found in the literature, an evaluation of the dental arches form, dimension and teeth position is necessary, considering the individual characteristics of each patient. The aim of this study was to define the dental position by determining the linear and angular deflections averages in the horizontal plain. A sample of 61 pairs of plaster models obtained from 12 to 21 year-old leucoderm Brazilian adolescents with normal occlusion were prepared and inserted in CorelDraw 9 software from an occlusion view, then curves and lines which defined the linear and angular deflections at the upper and lower arches were obtained. Based on the results, for this sample, it was possible to conclude that for the upper arch the lateral incisors position was lingual when compared to the central incisors and canines; the canines position was vestibular when compared to the central incisors and lingual when compared to the first bicuspids; between the bicuspids there were no position deflection; the second bicuspids position was lingual when compared to the first molars; and the second molars position was lingual when compared to the first molars. For the lower arch the canines position was vestibular when compared to the incisors; the first bicuspids position was lingual when compared to the canines and second bicuspids; the second bicuspids position was vestibular when compared to the first molars; and the second molars position was lingual when compared to the first molars. Concerned with what was found by the angular deflections, except for the inferior second molars compared to the first molars, all distal faces on the vestibular faces of both superior and inferior molars were lingual positioned when compared to the mesial faces.
