What’s Three-Jaw Surgery?

Three-jaw surgery is a combination of two-jaw surgery and mouth protrusion correction surgery that corrects mouth protrusion and severe microgenia at the same time.
Premolars after the incisors are removed, frontal gum bone and teeth are moved backwards, correcting mouth protrusion. Then, with two-jaw surgery, three-jaw surgery corrects severe microgenia.

“Three-Jaw Surgery for Protruded Mouth and Severe Microgenia”


Three-Jaw Surgery operates two-jaw surgery and mouth protrusion correction surgery all at once

It might not be sufficient to correct mouth protrusion and microgenia with only mouth protrusion correction surgery or two jaw surgery. In order to have a balanced positioning of upper and lower jaws, three-jaw surgery is the answer.

Correction with mouth protrusion correction surgery
Corrects mouth protrusion by moving gum bones backwards, but worsens microgenia with even more backward positioned lower jaw
correction-with two-jaw-surgery
Correction with two-jaw surgery
Only two-jaw surgery correction but unable to move lower jaw forward enough to correct microgenia because of mouth protrusion
Correction with three-jaw surgery
Incises ulitis (gum bone) to correct protruding gum bone, moves lower jaw forward enough to correct microgenia, correcting both simultaneously
