title: A case of Class II malocclusion associated with a deeply impacted maxillary central incisor.
abstract: The patient was a 9-year-old girl with a skeletal Class II malocclusion characterized by maxillary protrusion, excessive overjet and deep overbite. The patient's maxillary left central incisor was deeply impacted. During the first stage, a lingual arch was employed after surgical exposure. During the secondary stage, all four first premolar teeth were extracted and then edgewise mechanotherapy was performed. The total treatment time was 6 years. The malocclusion was treated satisfactorily and resulted in correction of the esthetic and functional flaws after 1 year out of retention.
