Summary

This study aims to investigate the effect of 3 randomly applied interceptive measures (slow maxillary expansion, extraction of deciduous canines and no intervention) on maxillary canine impaction in patients with early mixed dentition and lack of space in the dental arch. Additionally, these groups are compared with a control group with adequate space. Patients with at least one impacted maxillary canine, presence of deciduous canines and absence of crossbite were included. The canine position is assessed by measuring five variables (sector of the canine cusp, canine to midline angle, canine to first premolar angle, canine cusp to midline distance, and canine cusp to maxillary plane distance) on 2 panoramic radiographs at 0 (T1) and 18 months (T2).
