Distraction osteogenesis is a procedure used to increase bone in order to correct facial deformities or to provide additional bone for dental implant rehabilitation. The procedure requires an initial surgery to create separation of the bone followed by slow separation (distraction) allowing for bone to fill in the gap. Although the treatment time for distraction is longer than traditional surgery, it tends to be more stable when large movements are necessary and eliminates the need for bone grafting. Distraction osteogenesis involves inserting a small device within the mouth and requires the cooperation of the patient to activate the appliance daily until the desired gain in bone has been accomplished. Although this procedure results in less pain and swelling than traditional surgery, there will be more follow up visits at our office to closely monitor your progress.
