Mid-maxillary distraction osteogenesis of cleft patients using a special custom-made tooth-borne device.

A relatively new approach to maxillary advancement by maxillary distraction using a combined surgical and modified orthodontic technique is described. This protocol and the technique have been used for the past 3 years (2006 to 2009) on more than 60 patients, aged between 14-29 years. Distraction of between 7 and 18 mm has been achieved, creating class 1 or mild class 2 arch relationships in cleft lip and cleft palate patients who had class 3 arch relationship compounded by significant maxillary retrusion. The technique is simple, inexpensive and less time consuming.
