Skeletal and dentoalveolar dimensions in unilateral impacted canınes: a cone beam computed tomography study

Abstract

Purpose To compare skeletal and dentoalveolar measurements of subjects with unilateral impacted canine versus the non-impacted contralateral side using cone beam computed tomography (CBCT). Materials and Methods 30 CBCTs with unilaterally impacted maxillary canines (Buccal=15, Palatal=15) were selected. Skeletal and dentoalveolar variables (alveolar ridge height of incisors, dentoalveolar height, angulations of incisors and canines, basal lateral width and premolar width) were compared between the impacted and the contralateral sides. Independent t-test was used to compare the variables. Results There was a significant difference in the mean basal lateral width between the impacted (28.25±1.83 mm) and non-impacted (31.64±2.18 mm) sides. Premolar width was significantly lower on the impacted side (p
