Usually, those with protruded mouth have protruded cheekbones as well.
In this case, ordinary facial contouring surgery alone is not enough to provide dramatic
surgical outcomes.
WONJIN’s total Maxillofacial or Two Jaw Surgery involves in giving resolutions for both
aesthetic and functional problems at the same time.
Elongated/protruding

Jutting chin
Flat face
(face with lack of volume)
Protruding mouth
(bimaxillary prognathism)

IVRO is a method of Two Jaw Surgery that vertically fractures the posterior
section of the mandibular bone. It avoids using plates or wires as a fixator
to allow for the jaw to function naturally after the procedure,
which is much more convenient for patients during post surgical recovery.
Additionally, the fracture line on the posterior section provides a slimming
effect and it moves the lower jaw to the backward to improve with
protruded lower jaw.
SSRO is a method that fractures the mandible near the molar,
and the bone is fractured in two sections and removed,
then reconnected for fixation.
This method is known for its short recovery period, because the
reattachment area has a larger surface area which helps the bones adhere
more effectively for faster recovery.
Additionally, postoperative oral-fixation period is considerably short.
Two jaw surgery is known as orthogenetic surgery which helps to improve
both upper and lower jaw at the same time.
After making an incision inside of the mouth is made, the upper and lower
jaws are fractured.
Then the bone will be moved to the most appropriate position.
In order to prevent this position from shifting, metal pins will be fixed.
Step 01
Osteotomy on upper
jaw and lower jaw
Step 02
Move the fractured
bone into the
appropriate position
Step 03
Fixate the bones for
safe positioning

Partially fixate using rubber

Pre-existing complete fixation method disabled food intake and daily activities immediately after surgery.
But with the development of technology and surgery skills of WONJIN, self fixation and non-fixation methods enable easier jaw movement and return to
daily activities such as eating, talking, oral rinsing after the surgery.
Hospitalization (3 nights and 4 days)
Daily activities are possible
Anti-swelling care
Remove the rubber band inside the mouth
Remove the wafer / Orthodontic diagnosis
Start Orthodontic.
There are 3,6,9,12 months regular check up after the surgery.
A year after the surgery regular check up every 6 months is required until 3 years from the surgery date.
The check up schedule may vary by individual.
