With the advancements in surgical techniques and knowledge, today bimaxillary surgical procedures are frequently used to correct this anomaly so that only mandibular set back operations had been performed in the past. Distraction osteogenesis or callus distraction, which is a process of bone regeneration between the surfaces of vascularized bone segments separated by gradual distraction is a method of bone generation without using bone or soft-tissue grafts. The purpose of this report is to present the orthodontic-orthognathic treatment of a patient with severe Class III skeletal malocclusion having ankylosing spondylitis with the use of a rigid external distraction and mandibular set back technique.
