Distraction osteogenesis is a modern surgical technique used to lengthen and reshape bones in the face and jaws. Instead of traditional grafting methods, this procedure encourages the body’s natural ability to generate new bone by gradually separating two bone segments and allowing new bone to form in the gap.

Originally developed for orthopedic surgery, distraction osteogenesis is now widely used in oral and maxillofacial surgery to correct jaw deformities, congenital defects, or trauma-related deficiencies. It can also be an effective option for patients who lack enough bone for dental implants.

When is Distraction Osteogenesis Used?

  • Correction of small or underdeveloped jaws

  • Treatment of congenital conditions (such as cleft-related deficiencies)

  • Repair of traumatic bone loss or deformities

  • Increasing bone height or width for dental implants

Procedure Overview:

  1. Surgical Placement – A small device called a distractor is surgically placed on the bone.

  2. Latency Period – A short healing time allows initial bone repair to begin.

  3. Distraction Phase – The device is gradually turned (usually 1 mm per day), moving the bone segments apart and allowing new bone to form in the gap.

  4. Consolidation Phase – Once the desired length is achieved, the device remains in place until the new bone hardens and matures.

Advantages of Distraction Osteogenesis:

  • Creates natural bone without the need for bone grafts

  • Allows simultaneous soft tissue growth (muscles, skin, nerves adapt along with bone)

  • Provides long-lasting, stable results

  • Minimally invasive compared to large grafting procedures

At 32 Pearls – Dr. Sameer Kaura’s Clinic, distraction osteogenesis is performed with precision planning using advanced imaging and surgical techniques. This innovative treatment provides patients with improved function, facial balance, and the possibility of successful implant placement when traditional methods may not be effective.
