Ameloblastic fibroma (AF) is rare benign tumor that typically occur in the mandibular molars of young patients. The frequency of AF is 1.5% to 4.5%. According to the World Health Organization classification of 2017, AF are benign mixed tumors composed of odontogenic mesenchyme resembling dental papilla and epithelial tissue resembling odontogenic epithelium. The principal treatment of AF is enucleation of the tumor along with extraction of the involved teeth. Therefore, in young patients, extraction of permanent teeth leads to loss of normal occlusion. We report a case of AF in a young patient, whose jaws was growing, treated conservatively with 8 years of observation, orthodontic treatment including upright surgery. Recurrence of AF has not been noted, and the impacted tooth has erupted to the nomal occlusal plane.
