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

Key techniques of ID hospital

Set-up model

The first step to have no difference between the surgery plan and result is to mount the upper jaw in the proper position. Teeth occlusal status after the jaw surgery can be predicted without pre-surgical orthodontic treatment by making a dental mold and analyzing dental problems and making setup model.

Inter-department planning conference

Plastic surgeons, oral and maxillofacial surgeons, and orthodontists have communications for every patient and together they set up the optimal treatment plans for the patients by predicting the movement of the patients jaw and change of the occlusal status.

Multiple-segment surgery

The surgeons in ID hospital have the skills and experience for performing upper and lower jaw surgery by cutting the jaw in multiple segments. By using this technique, it is able to move the jaw in nearly any direction that is needed for the optimal result. Even with patients who was said to be inoperable in other hospitals, it is possible in ID hospital.

Skeletal Anchorage System (SAS)

Compared to conventional orthodontic methods, the SAS allowed for enhanced dental movements during the treatment period.
