title: Orthodontic treatment for an unerupted and severely rotated maxillary central incisor. A case report.
abstract: BACKGROUND
  Many reports have indicated the treatment for permanent teeth with disturbed eruption due to the presence of supernumerary teeth. However, successful treatment for an unerupted maxillary incisor with severe rotation and another maxillary incisor with disturbed eruption by a supernumerary tooth is quite rare.
  
  
  METHODS
  We treated a 7-year-old Japanese male with an unerupted and severely rotated maxillary right incisor, along with a maxillary left incisor due to interference with eruption by an inverted supernumerary tooth. Orthodontic treatment using surgical exposure, traction and guidance of the rotated right incisor, and maxillary expansion following extraction of the supernumerary tooth were performed.
  
  
  RESULTS
  At 27 months following extraction of the supernumerary tooth, and comprehensive orthodontic treatment led the malposititioned central incisors to a functional position and stable occlusion.
