Stable vertical distraction osteogenesis of highly atrophic mandibles—a salvage pathway for mandibular reconstruction prior to oral rehabilitation with dental implants

Abstract

Mandibular reconstruction is still a challenge for surgeons. Distraction osteogenesis (DO) might contribute in certain instances to solve this problem. A principal advantage of DO is the expansion of the surrounding soft tissues that accompanies the bony regeneration. In addition there is no donor site morbidity when compared with reconstruction by autologous bone grafting. However its application may be limited by the thinness of the mandible and the attendant fracture risk. This article describes a technique that combines stable internal fixation with vertical distraction of the alveolar ridge in patients with critical mandibular thickness after ablative surgery for cancer of the oral cavity.
