Abstract

Transverse maxillary deficiency or maxillary atresia is a dentofacial deformity characterized by the presence of unilateral or bilateral posterior crossbite, ogival palate, dental crowding, nasal breathing difficulty, zygomatic hypoplasia, narrow nasal base and deep nasolabial sulcus. Treatment is based on maxillary expansion by orthodontic treatment in adult patients, performing osteotomies to weaken the areas of bone resistance to disjunction. The purpose of this article is to present the case of an adult patient who underwent surgical maxillary disjunction associated with a Hyrax-type orthodontic appliance. The patient has been under follow-up for 12 months and showed significant improvement in dental occlusion due to the regularization of the apical bases with the transverse correction procedure.

Keywords: maxilla; dentofacial deformity; osteotomy.
