Unilateral Posterior Crossbite - Shoot It At Sight. A Review

Abstract

This review is undertaken to see the effects of early orthodontic management of unilateral posterior crossbite (UPC). UPC is often accompanied by lateral mandibular shift and mandibular deviation because of the reduction in the width of the maxillary dental arch. Correction of early orthodontic treatment of UPC is more complex than it appears. Treatment success is high if it is started early. To develop an appropriate treatment plan , it is first necessary to determine if there is a functional jaw shift on closing, it is dental ,skeletal or both or it is related only to maxilla or both the jaws. Evidence that crossbite are not self-correcting and have some association with TMJ disorders. It can be difficult to treat UCB in adults without a combination of orthodontics and surgery. Treatment of UCB generally involves symmetric expansion of the maxillary arch, removal of selective occlusal interferences and elimination of the mandibular functional shift. The general practitioner or dentist must be able to diagnose UPC successfully and provide treatment or referral to take advantage of the benefits of early treatment.
