Jaw Distraction Before & After Photos


Jaw Distraction Before & After Case 1




Jaw distraction surgery is used when the amount of movement is too large for a single surgery.

In this case, a patient with Crouzon syndrome planned for dental restoration. The upper and lower jaws were much more than 10mm offset, which is the usual cutoff to consider distraction surgery.

A 3D-printed model and guides were used for precisely planning the placement of the osteotomies, plate positioning, and the vector of distraction.

The use of internal distractors avoided the use of a large, external halo device. No external scars, wires, or screws were needed.

After placement of the hardware, the upper jaw was advanced a little every day until we reached our goal of lining up the upper and lower jaws.

The patient is seen here after the bone has solidified, and the distractors have been removed.

You can see an improvement of her facial profile and balance, with the upper lip now better supported as well.

The posts for dental implants were able to be placed at the time of distractor removal as well.

We can’t wait to see her final results!

Jaw Distraction Before & After Case 2



Treacher-Collins syndrome affects about one in every 50,000 children, and varies widely in severity from one patient to another.

There is underdevelopment of the cheeks and jaws. This affects the shape and size of the orbits, cheeks, and jaws.

For this patient, the small lower jaw made her airway too small for her breathing needs. Her tracheostomy site was unable to heal because of this, despite a previous jaw distraction.

3D modeling and planning was performed to give the best chance at protecting her tooth buds and nerves, while having enough solid fixation to grow new bone, pushing her jaw forward in the process.

Over a couple of weeks, the mandible was moved out a millimeter at a time.

The hardware has since been removed, with good bone healing.

We look forward to having her tracheostomy removed and healed soon!
