The upper jaw (maxilla) was very narrow and constricted. A transpalatal, tooth-borne, univector distractor was custom-made. The bone of the roof of the mouth (palate) was cut, distractor device placed and with the process of distraction osteogenesis, the maxilla was widened, correcting bite, teeth arrangement and appearance.
Palatal distractor placed to treat contsricted upper jaw
Using distraction, upper jaw expanded correcting crossbite
A patient had a severely constricted and narrow lower jaw (mandible) due to Hanhart Syndrome. The mandible was cut in the midline. A mandibular symphyseal distractor placed. The device was turned gradually pushing the bone segments apart. New bone formed in the resultant gap and the lower jaw was subsequently widened
