Before & After

What is Self Two Jaw Surgery?

It is a type of Two Jaw Surgery for those who have malfunctioning due to long face, jutting chin, asymmetric face and jaw problems which allows the patient to choose either fixation or non-fixation method after Two Jaw Surgery. Self Two Jaw Surgery can provide more natural result with higher satisfaction since this procedure applies the advantages of both fixation and non-fixation method.

Appropriate for those who

  1. Have abnormally long face
  2. Have asymmetric face
  3. Have protruded mouth that cannot be improved by previous protruded mouth surgery
  4. Jutting chin with malocclusion
  5. Have mouth that shows too much gum when smiling
  6. Have incorrect center-line of upper teeth

Self Two Jaw Surgery is three-dimensional surgery.

If Facial Contouring Surgery on forehead, cheekbone, and square jaw is considered as two-dimensional procedure, Two Jaw Surgery is considered as three-dimensional procedure. This is because of the three-dimensional change after Two Jaw Surgery which allows not only the overall face line but also the jaw’s location and angle can be corrected very precisely.

Three-dimensional effect of Two Jaw Surgery

Angle adjustment of aesthetic line
By adjusting the fine angles of upper and lower jaw to achieve perfect aesthetic line from nose tip to end of the jaw.

Length adjustment of upper and lower jaw
Middle of the face and lower jaw length can be adjusted.

Position adjustment of front and back location
Upper and lower jaw is retruded and positioning may adjusted.

Face dimension adjustment
Reduce the face dimension for slimmer face.

Occlusal adjustment
By adjusting the upper and lower teeth for correct dental biting and beauty.

Functional Improvement & Cosmetic Effect

Two Jaw Surgery and Occlusion

What is Malocculusion?

It is the condition when upper and lower teeth do not occlude. When this condition gets worse, the external appearance gets worse aesthetically and the biting ability decreases which can cause jaw joint disabilities.

Cause Symptoms
-Genetic effect
-Wrong posture or habit
-Teeth size or shape problem
-Birth defect
-Decline of digestive function
-Incorrect pronunciation
-Jaw joint
-Herniated cervical[lumbar] disc

Why is Two Jaw Surgery necessary?

It may be the purpose of occlusion improvement, but it is also important to return the occluding ability with correct pronunciation. Also in case of bone related malocclusion, Two Jaw Surgery for changing the position of the jaw will bring the best result in both functionally and aesthetically.



Second effect of Two Jaw Surgery – Cosmetic Effect

“Functional improvement can be made from Dental Clinic. Beauty can be achieved at Plastic Surgery Clinic. If you want both, Wonjin is the answer.”
Two Jaw surgery improves both function and aesthetic. Especially, it can relocate the jaw position to achieve the ideal face ratio which cannot be achieved without Two Jaw Surgery.

Dentist may improve the functional matter but aesthetic improvement is expected to be low. There is almost no Plastic Surgery Clinic that has well-organized system for beauty improvement.

Thus, Wonjin is the place for the perfect Two Jaw Surgery.


Upper Jaw Surgery

Recommended for those who

1. Have imbalance jaw due to less developed upper jaw
2. Have severe face asymmetry
3. Have abnormal length of upper and lower jaw
4. Have possibility of open bite after surgery

The result of the upper jaw surgery is affected heavily on the surgeon’s skills. The level of experience and know-how is compulsory to provide customized design and precise performance for the good result.

Lower Jaw Surgery

IVRO and SSRO are two surgical methods for Lower Jaw surgery. The surgical method may vary depending on patient’s condition or clinic. Wonjin experienced numerous cases of operations to provide accurate diagnosis and plan the surgery accordingly for higher satisfaction.

SSRO is the method of cutting the jaw bone diagonally into two plates then fixates the bones to the back.

SSRO is a very complex procedure which requires high skills because cutting the jaw bone that is consisting of blood vessel and nerves is dangerous which can lead to jaw joint problem. Therefore, it is extremely important how precisely the surgeon excise and fixate the bone with good post-operative correction.

The importance of the plate to safely fixate the divided bones into one, the plate’s fixation power is very important. The fixation power is highly affected by the quality of the plate.


Requirements of Superior Plates

Power: Must have enough strength to maintain the position of the fixated bone without falling off or loosing.
Tension: Tension must be maintained for at least 10 weeks (minimum period for bone to heal)
Affinity: Chemical affinity with the bone is important since the plate is inserted into the body either permanently or for a long period.

Wonjin only uses high quality plates.

– Materialized for jaw structure for natural shape to reduce the surgery time.
– Flexible adjustment is possible to reduce the difficulty of readjustment.
– Decreased the possibility of infection or foreign body reaction of the plate.
– It is produced for an accurate adhesion and stable fixation.
– Almost no possibility of strain or damage.
※ Interlink of the bone, screw, and plate is very important for safe fixation. If not, it can lead to revision surgery

IVRO (Intraoral Vertical Ramus Osteotomy)

Human body has the regeneration ability, which has a habit of going back to an optimum state if damaged. This IVRO method makes good use of the habit, and for the best result, the surgeon’s surgery experience and know-how is required.

IVRO makes excision on the lateral part of the jaw bone to find the optimum location without the help of fixating with pins or wires. Since this method does not perform fixation on the bone, it reduces the chance of jaw joint problem or pain to reconstruct the function.


Wonjin’s Surgical Method, ‘Virtual Operation’

The reason why it is possible

It took a long time to get to Busan from Seoul, but nowadays, it takes less than 4 hours with the development of transportation such as KTX and aircraft. Likewise, with the advanced technology of 3D simulation programs, we can accurately predict the post-operative result.

This so-called ‘Virtual Operation’ reduces inconvenient procedures of pre-operative orthodontic treatment which also drastically reduces the recovery time and cost but this procedure must be backed up by an accurate diagnosis and rich experience and know-how for the good result.

The advantages of ‘Virtual Operation’

1. Improvement of appearance with jaw correction before the actual surgery.
2. By improving the bone structure problem first, it drastically reduces the orthodontic treatment period.
3. The prediction of the surgery is very accurate.
Previous Surgical Method, ‘Pre-operative Orthodontic Treatment’

‘Pre-operative Orthodontic Treatment’ is to make the occlusion easier after the surgery by moving the teeth. This also requires post-operative orthodontic treatment after Two Jaw Surgery. In the past, where Two Jaw Surgery was not popular, this surgical method was widely used. With the increasing Two Jaw Surgery cases and advanced technology, this pre-operative orthodontic treatment is not required with the help of predicting equipment.

Decreased Error Range and Increased Safety

through Wonjin’s Surgery Plan using ‘Virtual Operation’


STEP 01 Paper Surgery

With the precise measurement data by 3D CT, design an accurate treatment plan on the paper.


STEP 02 3D Surgery

Establish a highly accurate surgery plan through analyzing the face transformation on various angles with our SOPP.


STEP 03 Model Surgery

With the gathered information through 3D CT and X-ray, proceed a mock surgery with custom-made occluder.

Fixation Method of Self Two Jaw Surgery


Fixation method in the past – Complete Fixation

Due to lack of advanced equipment in the past, wire or band were used for intermaxillary fixation after the surgery. This method involves in fixation of both upper and lower jaw which lead to problems with breathing or eating. To overcome the problem, Non-fixation or Self Fixation method is more popular for Two Jaw Surgery patients.

*Intermaxillary Fixation: fixation of upper and lower teeth for adjusting the upper and lower jaws to good location


Latest Fixation Method – Non-fixation Two Jaw Surgery

Non-fixation method requires high surgical skills to carry out an accurate surgery plan since it does not involve intermaxillary fixation. This method has the advantage of faster recovery and easier food ingestion.


Self Fixation Two Jaw Surgery

Self Fixation method has both advantages of convenience from non-fixation method and the safety from complete fixation method. This method allows free movement of the jaw since it only fixates two parts with bands.
