What is Two jaw Surgery?

In cases where the mandible protrudes out more than the upper jaw does, such as mandibular prognathism,
long face, or facial asymmetry, more often than not, a maloccluding dental interlocking may also largely occur.
In such cases, the position and function are abnormal.

Two jaw surgery is an operation that corrects the position by fracturing the upper and lower jaws. Aesthetic goal and the functional target of dental interlocking
must all be satisfied. The surgical outcome is dramatic, and there is also a significant change in a patient’s appearance.

Target indications for Two jaw surgery

Facial asymmetry with an
unbalanced and bent chin

Mandible prognathism
with long and
protruded mandible

Mouth protrusion
with bulging of both
teeth and gums

Cases with either
a malocclusion or
an open bite

Overall elongated face

Flat face

Technique of Two jaw Surgery

Sagittal Splitting Ramus Osteotomy (SSRO) and Le Fort fracture procedures are performed
at Apgujeong YK Plastic Surgery Clinic.

Advancements in line surgery are possible due to considerable progression in orthodontic procedures,
rather than that of surgical methods.

In the past, it was demanding to carry out a proper occlusion suitable for the resultant shape of a facial surgery. Now, even
a movement of the premolar and molar have become facilitated. Thus, once a shape of the face has been created, any dental work/tooth
fitting can be fitted onto the face. Cases of line surgery largely show malocclusion after surgery. However, a patient can undertake
postsurgical orthodontic treatment, preventing recurrences while attaining stable dental occlusion.
