Orthopantomographic analysis of the intraosseus position of the maxillary canines.

The aim of this work was to analyse the intraosseous position of the maxillary canine in orthodontic patients. It was an exploratory pilot study prior to the next research work to develop a predictive model based on a regression analysis initially including a large number of variables. 105 subjects from 6 to 12 years from both genders were included in this study. Four variables were used. The study showed that there was no marked gender dimorphism concerning the intrabony position of the canine; the latter is quite similar on both sides, and the older the age, the smaller the angulation of the canine. The values obtained for the angulation of the canine, its depth of impaction, its position in relation to the lateral incisor and the premolars, correspond to an average impaction severity and treatment difficulties.
