What is mandibular distraction osteogenesis?
Mandibular Distraction Osteogenesis (MDO) is a surgery done for infants with Pierre Robin sequence. MDO lengthens the jaw to help open the airway so the baby can breathe safely and comfortably on their own.
What is distraction osteogenesis in orthodontics?
Distraction osteogenesis (DO) is a surgical-orthopedic method for lengthening bone by separating or distracting a fracture callus. It represents an important technique for surgeons and orthodontists to reconstruct and recontour the facial skeleton.
What is distraction surgery?
Distraction osteogenesis is a technique in orthognathic surgery that expands or stretches bone in the jaw. Simply stated, distraction osteogenesis means the slow movement apart of two bony segments which allows new bone to fill in the gap created by the bony segments.
What is distraction osteogenesis in dentistry?
Distraction osteogenesis is a way to make a longer bone out of a shorter one. After a bone is cut during surgery, a device called a distractor pulls the 2 pieces of bone apart slowly. The slow stretching apart of bone is not painful. Children say it hurts less than braces they wear to straighten teeth.
