As in the traditional combined surgical and orthodontic procedures, an Orthodontist can plays vital role in treatment planning and the orthodontic treatment of patient undergoing distraction osteogenesis. This role includes predistraction assessment of the craniofacial skeleton and occlusal function, pre-distraction, and post-distraction orthodontic care. Based on clinical evaluation, dental study models, photographic analysis, cephalometric evaluation, and three-dimensional computed tomographic analysis, the Orthodontist, in collaboration with the Surgeon, plans distraction device placement and the predicted vectors of distraction. Finally, as in other forms of orthognathic surgery, the practice of distraction osteogenesis depends on the cooperation and planning between orthodontist and surgeon as a team. Purpose of this paper is to review biomechanics and orthodontic treatment protocol of distraction osteogenesis in the maxillofacial region.
