Vector control in alveolar distraction osteogenesis.

Distraction osteogenesis is a surgical technique which utilizes the body's own reparative mechanisms for hard and soft tissue reconstruction. It has numerous applications in the maxillofacial complex, and has been successfully used for vertical and horizontal augmentation of alveolar ridges future prior to implant placement. In our opinion, this method is a useful and acceptable alternative to conventional bone grafting techniques in a selected group of patients. Although the concept of alveolar distraction is exciting, and has certain specific advantages (eg, soft tissue regeneration, predictable augmentation of height in the posterior mandible), optimal vector control of the distraction regenerate remains an issue of critical importance. The purpose of this article is to present our experience with some simple techniques that we have successfully used at our center for proper vector control during internal alveolar distraction osteogenesis.
