Alveolar distraction: a possible new alternative to bone grafting

Distraction osteogenesis is a new concept to periodontics that may replace the more traditional bone grafting techniques of onlay grafts and titanium membrane procedures. Distraction osteogenesis is not fraught with the complications of graft and membrane exposure or inadequate tissue coverage, which makes the distraction procedure an ideal technique to grow unlimited amounts of vertical bone height. This article describes a technique to grow new bone and soft tissue in a maxillary alveolar defect using a new technique called alveolar distraction osteogenesis. A case report is presented of the distraction procedure, reentry 6 months later, implant placement, and restoration.
