Distraction Osteogenesis is a reconstructive technique used to gradually grow new bone in the upper or lower jaw. It can add length, width, or height to deficient bones and help create the foundation needed for improved function, aesthetics, and future orthodontic or dental treatments.
Distraction Osteogenesis is a method of gradually extending bone using what is called controlled distraction forces. During surgery, your surgeon will make small, precise cuts in the bone to separate it into sections. After a short healing period, a small device that has been attached to the bone is gradually adjusted to apply gentle force, moving the bone segments little by little into their new positions. As the spaces between the sections slowly widen, new bone forms in between, lengthening or widening the jaw, and creating tooth-bearing alveolar bone to support Dental Implants or necessary orthodontics.
Before surgery
Your surgeon evaluates the jaw deficiency, the bite relationship, and your overall treatment goals to determine whether Distraction Osteogenesis is the right approach. Imaging and treatment planning help map the procedure, device placement, and timing for any related orthodontic or restorative care.
During surgery
The jawbone is surgically divided, and the distraction device is placed. After a short healing period, the device is activated gradually to move the bone segments apart in a controlled way. As the space opens, new bone forms between the segments while the jaw is lengthened or widened.
After surgery
Once the desired movement is achieved, the bone is left in place to consolidate and harden. After the new bone has matured, the distractor is removed. Additional treatment such as orthodontics, bite correction, or implant planning may follow depending on the original goals of care.
Distraction Osteogenesis is a reconstructive technique used to lengthen or rebuild areas of the upper or lower jaw by gradually creating new bone. It may be recommended for patients with a short lower jaw, a narrow upper jaw, or areas where additional bone is needed to improve function, support orthodontic treatment, or prepare for future Dental Implants.
In the first procedure, your surgeon performs the planned bone cuts and places the distraction device in the treatment area. The device is positioned so it can gradually move the bone in the intended direction after an initial healing period.
In many cases, yes. Once the desired movement is complete and the new bone has matured during the consolidation phase, a second procedure may be needed to remove the distraction device.
Recovery varies based on the area treated and the complexity of the case. Patients can expect healing after the initial surgery, regular follow-up during the active distraction phase, and continued monitoring during consolidation to make sure the bone is maturing properly.
During treatment, the jaw bone is carefully divided and a distraction, or separating, device is placed so the bone segments can be moved in a slow, controlled way. As the segments are gradually separated, new bone forms in the space between them, allowing the jaw to lengthen or widen over time.
After a short healing phase, the distraction device is adjusted in small increments over time. This controlled movement gradually guides the bone into its new position while the body forms new bone at the treatment site.
Treatment usually includes surgery, a short latency period, an active distraction phase, and a consolidation phase while the new bone matures. The exact timeline varies by case, but the consolidation phase alone is often about three months.
Unlike procedures that rely on grafted material to add bone, Distraction Osteogenesis uses your body’s natural healing response to generate new bone as the jaw is gradually moved. That makes it a useful option in selected cases where controlled skeletal movement and bone development are both needed.
