Abstract
ABSTRACT. Background: is necessary to consider which parameter should stablish the central incisor inclination. Purpose: The main objective of the present study was to appraise the possible concordance between the maxillary incisors inclination and the facial axis, the articular eminence inclination and the palatal functional inclination of the maxillary incisors. Methods: We perform an observational cross sectional study with 315 cone beam tomographic images from 63 healthy patients. Then a single technician carried out all the measures. The statistical analysis included T test, regression, and intra-class correlation. Results: There´s no statistical correlation between the articular eminence angle and the maxillary incisor inclination, nonetheless the facial axis present a low correlation and the functional palatal surface of the maxillary incisors present a high correlation with the inclination of the upper incisors. Conclusion: We conclude that the maxillary inclination could be answer by others functional factors such as neutral zone, occlusal function, and facial biotype except the articular eminence inclination. On the other hand, the facial axis should be taken into account in orthodontic planning treatment and could be a key factor to stablish the maxillary incisor inclination.
