Abstract

This 25-year-old male was characterized with mandibular prognathism and spaced dentition. We applied bilateral sagittal split osteotomy and genioplasty to set back the mandible and the prominent chin. The excess spaces of lower dentition were consolidated and then closed surgically by anterior subapical osteotomy. After treatment, his facial esthetics and occlusion were improved significantly. In the spaced dentition, the space closure by anterior subapical osteotomy after space consolidation may provide a more efficient alternative treatment.
