Inversion of premolars is an extremely rare condition, which usually requires extraction. This case report describes the inversion of an impacted maxillary second premolar in an 11-year-old male, and the multidisciplinary treatment approach for bringing the tooth into a normal position within the arch. In order to provide sufficient space for surgical reimplantation of the tooth, the mesially-drifted neighbouring maxillary first molar was first endodontically treated, followed by orthodontic distalization of the tooth. The inverted tooth was removed surgically and reimplanted without the use of splints for stabilization. After a 12-month follow-up period, the tooth maintained its vitality without any root resorption.Reimplantation of impacted inverted premolars can be a viable treatment alternative to extraction.
