Distraction osteogenesis is becoming the treatment of choice for the surgical correction of the craniofacial defects. Its principle is based on the studies of Ilizarov, who showed that osteogenesis can be induced if bone is expanded (distracted) along its long axis at the rate of 1 mm per day. This process induces new bone formation along the vector of pull without requiring the use of a bone graft. The technique also provides the added benefit of expanding the overlying soft tissues, which are frequently deficient in these patients. The case report highlights the procedure of vertical alveolar distraction osteogenesis in post traumatic defect of an 18year old male with rehabilitation with implant placement by the knowledge of clinical and research experience. It is a promising option to aid uneventful prosthodontic rehabilitation of severe vertically resorbed alveolar ridges and also in case of single unit missing teeth and emphasizes the critical role that basic science research has played in its evolution
