Distraction osteogenesis (DO) can be used to regenerate missing hard and soft tissue, Distraction osteogenesis relies on the body's ability to generate bone as two segments of bone are "distracted" apart. The osteotomies are created and the distraction device is placed. Typically, there is a latency phase of one week were a ?brovascular bridge is formed in the osteotomy site. This provides a template to generate new bone as the segments are distracted apart during the activation phase. Once the desired distraction has occurred, the device is left in place for a period of time. Once consolidation (typically 2 to 6 months) has occurred, the distraction device can be removed and implants can be placed. Chiapasco compared GBR to DO and found that both are equally effective in alveolar bone augmentation for implant placement and further stated that the long-term prognosis of vertical bone gain in DO is more predictable.
