Objective: To determine the Collum angle (CA) in the upper and lower central and lateral incisors in the different malocclusions using cone beam computed tomography (CBCT) Methods and Materials: Descriptive and cross-sectional study. 80 CBCT scans were evaluated using the Real Scan software 2.0, which were classified into class I, II-1, II-2 and III malocclusion according to the clinical records of the Orthodontic and Maxillary Orthopedics area of the teaching dental clinic of the Faculty of Stomatology of the Universidad Peruana Cayetano Heredia (FAEST-UPCH). The CA of the upper and lower incisors was calculated by subtracting 180° minus the crown-root angle. This angle was measured using the longitudinal axis of the crown and the longitudinal axis of the root in the sagittal plane. Results: The CA had a statistically significant difference (p <0.05) in the 4 upper incisors in class II-2 malocclusion compared to class I, class II-1 and Class III malocclusion, this being a CA of 14.70° in the right upper central incisor, 10.60° in the right upper lateral incisor, 12.45° in the upper left central incisor and 10.55° in the left upper lateral incisor. Conclusion: The CA was greater in the upper central and lateral incisors in the class II-2 malocclusion compared to the others evaluated by CBCT.
