Abstract

A 14 years young patient presented for the correction of a malocclusion that included a transverse maxillary deficiency. The patient had required to expand his upper jaw to correct his malocclusion. Recent evidence indicates that rapid palatal expansion (RPE) technique can be used without surgery in young adults; the decision was, therefore, made to treat the patient with RPE. RPE of the maxillary arch was achieved by means of a Hyrax appliance. The post-treatment radiographs revealed an opening of the midpalatal suture. It is still believed by clinicians that young adult patients require orthognathic surgery for palatal expansion, despite recent evidence supporting a nonsurgical approach after closure of the midpalatal suture.
