Treatment of a Class II Division 2 malocclusion with space reopening for a single-tooth implant

This case report describes the treatment of an adolescent girl with a skeletal Class II Division 2 malocclusion and impinging overbite. One of 2 previously extracted premolars had to be replaced by a single-tooth implant after adequate space reopening. An optimal overbite-overjet relationship was achieved through significant intrusion and proclination of maxillary and mandibular incisors. A horizontally impacted mandibular second molar was repositioned to ensure a 2-molar arch integrity. Resolution of the gingival smile line and favorable facial changes were also obtained.
