Adult skeletal Class III correction with camouflage orthodontic treatment: A 6-year follow-up

Abstract

This case report update follows the camouflage treatment of a 26-year-old woman with Class III skeletal and dental relationships and anterior and posterior crossbites. A conventional rapid palatal expander and facemask therapy were used to correct her crossbites and achieve Class I molar relationships. It is typically assumed that rapid palatal expander use results in dentoalveolar tipping and other side effects in adults. However, although the patient was an adult when orthodontic treatment was initiated, she did not demonstrate any significant side effects. At 6 years posttreatment, the patient was assessed using model superimpositions, the Yonsei transverse index, and midpalatal suture comparison. These tools showed that the patient's results and occlusion were stable.
