Vertical alveolar distraction can be a useful surgical technique in preprosthetic reconstructive surgery, especially after failed autogenous onlay bone grafting. The main advantage of this technique is to allow expansion of both the bone and soft tissue. Through a case of vertical alveolar reconstruction by distraction osteogenesis and implant rehabilitation in a patient who had undergone two previously unsuccessful interposition bone graft procedures, this report illustrate the advantages of alveolar ridge augmentation by distraction osteogenesis.
