Primary stability for an implant that is placed in a prostheticaly and aesthetically desirable position is of essential importance for a successful result. A limiting factor for achieving sufficient stability for an implant is insufficient volume of bone at the implant site. With the help of distraction osteogenesis, sufficient volume of bone can be generated at the desired implant site. Distraction osteogenesis can be adapted for reconstructing both extremely resorbed mandibles and local bone defects. The various distraction techniques for intra-oral bone defects are enossal, extra-cortical, and a combination of vertical and horizontal distraction.
