Correction of sever rotation of central maxillary incisor with fixed-removable ‎appliance in the mixed dentition stage: A case report

Mehrad Afzali, Samaneh Nakhaei, Raha Habib-Agahi


BACKGROUND AND AIM: The aim of this case report is to present an approach used to correct severe rotation of anterior maxillary teeth in a pre-adolescent boy.

CASE REPORT: The patient was an 8-year-old boy in the mixed dentition stage and severe rotation of upper right central incisor. Whip appliance was consisted of a removable plate, a cantilever spring and a bonded molar tube on rotated tooth. After initial alignment and overcorrection of rotation during 6 months, circumferential supracrestal fiberotomy was performed. About 1 week after surgery, the device was removed and the retention period initiated.

CONCLUSION: He semi-fixed-removable appliance can be very effective for correcting severe rotation of anterior teeth.
