The use of the mandibular sagittal split osteotomy for the correction of anterior open bite is still relatively rare. This bias is generally based on historical experience of treating open bite in the era of using wire osseous fixation and the belief that posterior facial height can not be increased. The stability of using rigid internal screw fixation and bilateral sagittal osteotomies in counterclockwise rotation of the mandibular body now has been demonstrated. Indications for considering a mandibular osteotomy in the correction of anterior open bite will be reviewed.
