Morphologic evaluation of the incisive canal and its proximity to the maxillary central incisors using computed tomography images

Abstract

The anteroposterior distance between the maxillary central incisor roots and the incisive canal was approximately 5-6 mm. More than 60% of the subjects had an incisive canal width greater than the interroot distance. Evaluation of the proximity of the incisive canal to the maxillary incisors, along with its dimensional characteristics, may be helpful when a considerable amount of maxillary retraction is planned.
