A case report of adult skeletal mesio-occlusion.

Abstract

The patient was a 22-year-old female with a class III malocclusion characterized by maxillary constriction, dental crowding and mandibular protrusion. The treatment goals which were related to the chief complaints included correction of negative overjet, negative overbite, and dental alignment. Since the pre-existing crowding created some severe problems and prevented adequate posterior repositioning of the mandible and anterior teeth, extraction of the four first premolars were recommended to correct the overjet. This treatment resulted in greater posterior repositioning. The treatment was divided into three stages: 1) extraction of first premolar teeth, alignment, space closure and an increase in the overjet and overbite, 2) arch alignment and detailing of the occlusion with a full fixed appliance, and 3) retainers. At the end of the treatment, the patient had an acceptable dental alignment with a class I molar relationship and an improvement in facial appearance.
