What is a mandibular distractor?

Jaw distraction surgery (mandibular distraction) Jaw distraction is the name for a surgical method of lengthening a small or recessed (hollow or indented) jaw. The medical term for jaw distraction is mandibular distraction osteogenesis (man-dib-u-lar dis-track-shon osti-oh-jen-esis).

What is distraction osteogenesis in oral and maxillofacial 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 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.

How much does distraction osteogenesis cost?

The cost for distraction osteogenesis will vary. In some cases, it will be combined with another jaw procedure. The technique itself starts at around $6,000 and increases (up to $12,000) depending on the severity of the condition being treated. In some cases, insurance may cover a portion of the procedure.

What is micrognathia associated with?

Micrognathia can present as a birth defect in numerous syndromes, including cleft lip, cleft palate, Pierre Robin sequence or syndrome, Stickler’s syndrome, Beckwith-Wiedemann syndrome, hemifacial microsomia, Treacher Collins syndrome and others.

What is mandibular Retrognathia?

Retrognathia is a term used to describe a mandible that is posterior to and behind where it should be when viewed from a lateral vantage point. Retrognathia should be diagnosed so that associated syndromes can be ruled out.

When is distraction osteogenesis used?

Distraction osteogenesis (DO) is used in orthopedic surgery, and oral and maxillofacial surgery to repair skeletal deformities and in reconstructive surgery.

What is the purpose of distraction osteogenesis?

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.

What is Pierre Robin Syndrome?

Pierre Robin sequence is also known as Pierre Robin syndrome or Pierre Robin malformation. It is a rare congenital birth defect characterized by an underdeveloped jaw, backward displacement of the tongue and upper airway obstruction. Cleft palate is also commonly present in children with Pierre Robin sequence.

What complications can be caused by distraction?

3 Distraction Device failure, pain at regenerate site, premature consolidation and interference due to device
4 Consolidation Infection, hypertrophic scar, incomplete ossification, regenerate fracture, relapse and TMJ disorders

What is distraction osteogenesis in dentistry?

Distraction osteogenesis (DO) is a useful technique for the reconstruction of deficient alveolar ridges. In addition to recreating bone, soft tissues including keratinized gingiva are created. DO affords the clinician to “overgrow” the bone thus allowing osseous recontouring at the time of device removal.
