Case report of an adult Caucasian female aged 23 years and nine months who complained of some difficulty in chewing and talking. Patient was diagnosed to have a mild Class III skeletal malocclusion with an anterior open bite of 4 mm. Treatment included combined orthodontic and orthognathic surgical approach. Surgery included surgically assisted maxillary expansion, advancement and impaction, a mandibular setback and a vertical, antero-posterior reduction genioplasty. The present case report illustrates a coordinated orthodontic and orthognathic surgical approach in the treatment of skeletal open bite deformities.
