A small or underdeveloped lower jaw can make it difficult to breathe comfortably, chew without strain, or speak clearly. Mandibular distraction osteogenesis (MDO) offers a gradual and precise way to address these challenges. By encouraging the jaw to grow new bone naturally, this technique can provide long-lasting results that improve how you breathe, eat, and speak.
What Is Mandibular Distraction Osteogenesis?
MDO is a specialized surgical approach used to lengthen the lower jaw. Unlike traditional jaw surgery, which repositions the jaw in a single step, distraction osteogenesis works in small, carefully controlled movements. As the jawbone is gently guided apart, your body responds by forming new bone in the space—allowing growth that’s stable, healthy, and uniquely your own.
Because this method uses the body’s natural healing ability, it often feels less invasive, with results that integrate seamlessly into your facial structure.
Who Can Benefit from Mandibular Distraction?
This treatment is used for both children and adults and can be life-changing for:
- Infants and children born with conditions such as Pierre Robin sequence, Treacher Collins syndrome, or micrognathia (a small lower jaw)
- Adults with a recessed jaw that affects both appearance and function
- Patients experiencing airway obstruction or sleep apnea due to jaw size or position
How Mandibular Distraction Works
The process begins with a precise surgical cut, called an osteotomy, made in the lower jawbone. A custom distraction device is placed to guide the bone’s movement.
In the weeks following surgery, the device is adjusted in small increments, gently lengthening the jaw. Each adjustment stimulates new bone growth in the gap. Once the desired length is achieved, the bone is given time to strengthen and fully heal. When healing is complete, the device is removed—leaving a jaw that functions better and creates a more balanced facial appearance.
Why Choose Mandibular Distraction Over Traditional Jaw Surgery?
MDO offers important benefits:
- Promotes natural bone growth, often without the need for large grafts
- Allows gradual, controlled adjustments for precision and predictability
- Improves both function and appearance by opening the airway and enhancing facial balance
Expert Care at Advanced Dental Implants & Oral Surgery
Our board-certified oral and maxillofacial surgeons have extensive experience in distraction osteogenesis and complex jaw reconstruction. Every treatment plan is built around advanced 3D imaging to ensure precise placement and adjustment of the device.
We often work alongside orthodontists, pediatric specialists, and sleep medicine experts, creating a coordinated care plan that addresses your functional needs and long-term goals.
What to Expect After Surgery
Most patients experience mild swelling or temporary discomfort in the days after surgery, which is managed with medication and at-home care. Follow-up visits are scheduled regularly to track progress and adjust the device as needed.
After the bone has fully consolidated, the device is removed. Depending on your overall treatment plan, additional orthodontic or restorative care may be recommended to fine-tune your bite and maintain the improvement in jaw alignment.
