Correction of a Severely Rotated Maxillary Incisor by Elastics in Mixed Dentition Complicated by a Mesiodens.

The aim of this case study was to report a potentially convenientapproach instead of a conventional orthodontic procedure forcorrecting severe rotation of anterior tooth of an 11-year-oldIndian boy, with a mixed dentition class I malocclusion. Thechild reported seeking treatment for severely rotated upper rightcentral incisor with mesiodens and a single tooth crossbite. Thesupernumerary tooth was first extracted and bondable buttonswere placed on the rotated tooth, an appliance composed of aremovable plate with Adam’s clasp with distal extension and aloop for engagement of elastics was delivered. Circumferentialsupracrestal fibrotomy was performed on the corrected derotatedtooth. Then, Hawley’s appliance with a z-spring and posteriorbite plane was fabricated and placed for correction of crossbite.Thus, this removable appliance can be a simplified and a costeffectivetreatment alternative for derotation of anterior tooth,especially during the mixed dentition period.
