What is Distraction Osteogenesis?
Distraction osteogenesis is defined as a surgical procedure for reconstruction of skeletal deformities by creating new bone and soft tissues in the region. In the craniofacial skeleton, the mandible, maxillae, zygomatic bone and in fact the entire middle third of the facial skeleton can be distracted. A very good indication is in cases where there is deficient growth in either upper or lower jaw.
Distractors are basically classified as either Intraoral (placed inside the mouth) or Extraoral (placed outside the mouth). The type of distractor device is selected as per individual patient needs. Distraction Osteogenesis has changed the face of reconstructive surgery in the recent years. The most important advantage of this procedure is that it grows new bone as well as soft tissues from the existing ones which impart maximum stability to the results as compared to conventional orthognathic procedures.
