Factors Influencing the Duration of Forced Eruption in Impacted Maxillary Canines

The aim of this study was to identify factors that affect the treatment duration and predict forced eruption in impacted maxillary canines using panoramic radiographs cone-beam computed tomography. This retrospective performed by reviewing medical records 73 patients (93 canines) from age 8 18 years who were treated with surgical orthodontic interventions on January 2012 December 2020 Ajou University Dental Hospital. Stepwise multiple regression analysis showed distance between canine cusp tip occlusal plane, mesio-distal location, bucco-palatal patient’s age, use rapid palatal expansion are significant regard eruption. There a statistically correlation angulation axis plane unilateral or bilateral impaction. It can be concluded could shorter when is closer located lateral incisor area, buccal middle, patient younger uses expansion.
