Conventional orthodontic treatment for isolated cleft palate with bilateral mild crossbite

Abstract This is a case report of a female patient who demonstrated bilateral posterior crossbite with isolated cleft palate. Molar relation was Class I on the right side and Class II on the left side. Maxillary dental midline was deviated 1.0 mm to the left. To establish the Class I relation, comprehensive orthodontic treatment without extraction was planned. Initially, an open coil spring was activated between the first premolar and the first molar to make space for the second premolar. Subsequently, Class II elastics were used to align the dentition and establish Class I relation. Bilateral crossbite was significantly improved, and the molar relation improved to Class I. Although the maxillary arch width was slightly decreased post-retention, intercuspation was maintained during the retention phase.
