Types of jaw surgery

Protruded Chin

Let’s have sharp chin line and small face at the same time!

Protruded chin that you couldn’t even hide! Small and beautiful face from every angle


Cases requiring surgery

If face or lower face is long
If the length of chin is long and chin is broad
If gum is exposed too much when smiling
If you have a protruded chin with facial asymmetry
If you have protruded chin with malocclusion
If lower teeth is more protruded than upper teeth

What is lantern jaw ?

Protruded chin is when your chin is protruded long and is not look good proportionally, and its another name is Mandilbular Prognathism.

In many cases lower teeth is protruded more than upper teeth so chewing ability is low, so many disorders like digestive problems and gastroenteric trouble can be followed. Also pronunciation problem can harm your impression.

A teeth structure can be fixed only by orthodontics, but if it is caused by skeleton structure it can be fixed by 2 jaw surgery that can solve fundamental problem.

Types of protruded chin


Macrogenia
In this case when you close your mouth with your teeth closed, occlusion is normal. Only lower chin is protruded to the lower or front direction and it loos like protruded chin, and it can be fixed by chin plastic surgery.
face23

Progathism
This case that jaw bone which is consisted of whole chin is located in front. Normality is that upper teeth are supposed to be protrude 1~2mm than lower teeth but in this case, it is the opposite so it needs correction.
This is when the overall chin is protruded. In normal case upper teeth should be placed 1~2mm

Types and diagnosis of protruded chin


General protruded chin
When chin tip is protruded and the mouth Is sunken and teeth is malocclusion

Long face and protruded chin
When chin and face are both long

Protruded chin with normal occlusion
Occlusion is normal but lower chin tip is protruded


Square protruded chin
When lower chin is wide and big

Middle of face hollow
When face around nose is flat or hollow

Facial asymmetry
When there is facial asymmetry together




Lantern jaw diagnosis process


3D CT scan
3D CT scan
We find out bone size, position, thickness and The exact distribution of nerve and blood vessel.

ST model production
ST model production
We make plan of surgery after reproducing ST model which is just the same as your actual bone structure.


Simulation
We make the best surgery plan based on Diagnosis of facial bone and occlusion, and Do simulation by simulation surgery system.


Surgical method of protruded chin correction

Orthodontics first, surgery next
Dentistry exactly predict how the occlusion is going to be after surgery, and then we correct uneven teeth before surgery and then do procedure. We set occlusion once more for 6 months after surgery so the detailed straightening is possible.

  • Even the slight asymmetry can be corrected as we correct occlusion first and then perform surgery, and then set occlusion again.
  • It can take longer time than setting occlusion after surgery, but we can prevent recurrence as much as possible

Surgery first, orthodontics next
This is the method of moving lower chin backwards and finishing it with orthodontics. But when your chin is deformed or occlusion is expected to be not correct the this method cannot be applied.

  • Since we perform two jaw surgery first you can see faster improvement.
  • Since we correct jaw first the duration of orthodontics can be shorten.
  • There could be problem with chewing ability since the occlusion is not perfect.

Chin tip operation
If the teeth is normal but chin tip is overly developed we downsize chin with horizontal osteotomy and move chin tip backwards and correct protruded chin.
face24

Mandible surgery
There are two kind of methods. The first is SSRO(Sagittal Ramus Osteotomy) and the next is IVRO(Intraoral Vertical Ramus Osteotomy).
face24

0 SSRO(Sagittal Splitting Ramus Osteotomy)
This method cut the back part of jaw bone vertically. Bones are fixed without medical pins.

Advantage Weakness
Stable conglutination is possible since cross section that is between bone is wide There can be pressure on chin bone because it is completely tied and you can’t move
The mouth is fixed by pins so the period of tying mouth is short Some nerves can be damaged
Lower chin is recovered fast earlier. Operation time takes longer than IVRO
When you get short chin surgery only SSRO is possible Complete recovery of lower chin might take longer than IVRO

0 IVRO (Intraoral Vertical Ramus Osteotomy)
This method cut bone slantly and remove part of bone. Bones are fixed with medical pins.

Advantage Weakness
Since we don’t fix bone there is less possibility of temporomandibular disorder and pain Since we don’t fix bone, the period of tying mouth is needed.
There is almost no possibility of nerve damage physical therapy is needed for functionality of lower jaw
Operation time is shorter than SSRO so possible to heal The first period the crossed part of chin can be touched
Bones are attached fast so recovery time is short. It is hard to be applied if it is short chin case.

Two-Jaw Surgery
In the case of protruded chin which upper jaw and lower jaw are out of balance two-jaw surgery is needed.
By moving existing chin position through two jaw operation to set occlusion of upper and lower tooth normally therefore could improve authoring capability and inaccurate pronunciation, also aesthetic factor will be able to be improved.

Long face

Find facial golden ratio and complete beauty

Worried about Long face , long chin? Find small and slim jaw line which is hid!


Cases requiring surgery

if face is long
If teeth and gum are espoused when smiles
If tip of the chin is long
If lower chin is big and face is long
If center of upper teeth is not correct
If both cheekbone is wide
If reoperation is needed

What is long face ?

If the middle of face that is from lower eyebrow to tip of the nose and from tip of the nose to tip of the chin compared with Length of forehead is long then we call it long face. There is a case that Simply face and chin is long , bimaxillary prognathism or lantern jaw symptom often appear.

In long face case, patients tend to breathe through mouth rather than nose and they used to twang so it is hard to give clear impression in personal relationship.

Long face diagnosis and types


General long face
When your gum is shown too much When smiling

Long face with protruded lips
When your profile is flat or protruded

Long face with protruded lips
When you have protruded lips with long face

Facial asymmetry long face
Long face which has facial asymmetry

Square jaw long face
Long face which has pachygnathous

Long face only tip of the chin
Only tip of the chin is long so face looks long




Treatment for each type of long face


Gummy Smile
If your gum bone of upper jaw has been overdeveloped vertically, your face became longer 2 jaw surgery is needed. In this case you cannot close your mouth completely and upper teeth are exposed too much as well as your gum.
After you become over 16~18 if 2 jaw surgery is performed that can shorten the upper jaw, you can get shorter face and have natural smile line and face proportion.
If you want to get only chin tip correction the overall compositional balance can be broken so you have to be careful.
face23


Openbite
When your face looks long because the occlusion is not correct you need 2 jaw surgery. If it is open bite both upper and lower teeth is not in occlusion and you feel hard to bite food and you have tendency to breath with your mouth with your mouth open and sometimes you speak through your nose.

In this case we can correct the position of jaws with 2 jaw surgery. In the case if malocclusion of both upper and lower teeth is severe you cannot get perfect occlusion only by having teeth correction and there is also high possibility of recurrence. In this case if you get 2 jaw surgery you can improve both occlusion and long face.

If only chin tip is long

If your bite is normal but chin tip is long, you can achieve harmonious compositional balance only by chin tip reduction .

Long face operation

Chin tip correction
If it is normal occlusion but only chin tip is protruded then this surgery can be applied.
We move back chin tip or move it upwards so effective correction is possible.
Chin tip correction

Lower jaw operation
There are two kind of osteotomy methods. One is Sagittal Ramus Osteotomy and the other is Intraoral Vertical Ramus Osteotomy.
SSRO(Sagittal Splitting Ramus Osteotomy)
This method cut the back part of jaw bone vertically. Bones are fixed without medical pins.

Advantage Weakness
Stable conglutination is possible since cross section that is between bone is wide There can be pressure on chin bone because it is completely tied and you can’t move
The mouth is fixed by pins so the period of tying mouth is short Some nerves can be damaged
Lower chin is recovered fast earlier. Operation time takes longer than IVRO
When you get short chin surgery only SSRO is possible Complete recovery of lower chin might take longer than IVRO

0 IVRO (Intraoral Vertical Ramus Osteotomy)
This method induces natural conglutination without using pins after cutting lower jaw vertically

Advantage Weakness
Since we don’t fix bone there is less possibility of temporomandibular disorder and pain Since we don’t fix bone, the period of tying mouth is needed.
There is almost no possibility of nerve damage physical therapy is needed for functionality of lower jaw
Operation time is shorter than SSRO so possible to heal The first period the crossed part of chin can be touched
Bones are attached fast so recovery time is short. It is hard to be applied if it is short chin case.

Two –Jaw surgery

If your overall face is long and it is accompanied by malocclusion, asymmetry, protruded lips and protruded chin, two jaw operation is needed.
By moving both upper chin and lower chin backwards and adjusting face length by applying chin tip surgery together the ideal face contour can be achieved.
We move upper chin and lower chin backwards and shorten the chin tip and create ideal face contour.

Protruded lip

Correction of protruded lips which finds you beautiful smile

Let’s smile brightly with new smile line after correction of both chin and teeth.


Cases requiring surgery

When only teeth are protruded
When your mouth is protruded and face is not long
When there is protruded mouth and short chin together
When you have long face and protruded lips together
When you have protruded lips even after a tooth extraction
When you have gummy smile
When you need reoperation

What is protruded lip ?

In Asian case, when connect tip of the nose and tip of chin , it is normal that connection is reached lips or positioned 1mm at the rear. If connection is reached too much you may doubt protruded lip but have to check size and position of bone , tooth right correction for correct diagnosis.

protruded lip diagnosis and types

  • when you measure the length from nose tip to chin tip with ruler, both lips reaches ruler so much
  • You unconsciously keep your mouth open
  • gum is exposed when you smile
  • You think you have short chin
  • Your lips look especially thick
  • if nasolabial angle is less than 90 degree and nose tip is sagged
  • If there is deep nasolabial fold
  • If your lips are protruded even if you had nose surgery and short chin surgery together

The cause of protruded lips

  • Hereditary reason
    Hereditary reason is the most common reason. Many Asian and black people have this and many Koreans have protruded lips because of this reason.
  • environmental reason
    Wrong respiration during childhood can make lips become protruded as one ages.

Method of protruded lips


Anterior Segmental Osteotomy

Anterior Segmental Osteotomy is the most generally used method and this is to remove inner teeth and gum and move remaining gum and teeth backwards. There is less bleeding and swelling, and the recovery period is short so daily activity is possible after 3~4 days after surgery.

face37

face37
Orthodontics
When teeth is only protruded you can expect good result after tooth extraction and teeth correction.
But even when gum is exposed you need surgery. The surgery plan of protruded lip correction is planned depending on face shape and the degree of protruded lips and it is general to get correction before or after surgery depending on individual’s condition.

Protruded lips


face37

Two-Jaw operation
When the protruded lips is occurred for multiple reasons, and long face and face asymmetry is accompanied by protruded lips, the correction is needed through 2 jaw surgery. The surgery is performed without tooth extraction and the degree of moving jaw backwards also can be adjusted.
This method can bring the biggest change since we move jaws backwards and shorten the length of upper jaw so it can reduce the exposure of gum.

Short chin

Create from nothing! Short chin correction!

Flat and blur line between neck and chin? Short chin correction for vivid V line!


Cases requiring surgery

When your chin is thick so you look dull
When chin tip is small or moved backwards
When you can hardly see chin line since chin is too short
When you have short chin and protruded lips together
When you need reoperation

What is short chin ?

We can call it short chin when lower chin is pushed backwards so it looks like short chin or when chin bone is small.
If you have protruded lips your chin can look short.

Short chin diagnosis and types

  • If your lower chin is small and short
  • If the boundary between chin and neck is not clear
  • If upper teeth covers lower teeth completely
  • If you close your mouth the power is needed on your chin tip


Short chin surgery method

Chin tip surgery
When the chin is not too short and the occlusion is normal this can be applied. There is no problem with teeth so the surgery is easier and simple.
We perform osteotomy or use implant. The surgery is performed in a short time so the swelling is short and you can expect satisfactory result.

face48

Mandible surgery
There are two kind of methods of osteotomy. The one is SSRO(Sagittal Ramus Osteotomy) and the other is IVRO(Intraoral Vertical Ramus Osteotomy). In the case of short chin only SSRO can be performed.
o SSRO(Sagittal Splitting Ramus Osteotomy)
Move severed jaw bone backwards and overlap and fix bone with pins and wire.

  • Early recovery of lower chin bone is possible
  • Since the bone is fixed firmly the period of tying mouth is short but there can be damage on nerve.
  • Since the cross section is wide the stable cohesion is possible, but since the chin is fixed firmly there can be stress on temporomandibular joint.

face48

Implants insertion
It is the method to implant goretex, silicon and medpor and adjust the size or position of your chin. This method has an advantage that if your chin is not too short you can receive surgery after simple partial anesthesia.

face48

Two-Jaw Surgery
When one’s chin is short and the lower teeth is abnormally retruded so the occlusion is not aligned.
We generally apply SSRO method to resect upper jaw and place it on the ideal position.

face48

Relationship between receding chin surgery and straining teeth

Short chin needs orthodontics like protruded chin. As lower jaw is moved to the front there should be malocclusion of teeth.
We decide if orthodontics is needed after detailed diagnosis. If one need orthodontics before surgery, the period is from 6months to 1year, and the period of orthodontics is 6months on average after surgery.

Facial asymmetry

Correct imbalanced face !

Find balance and change your face into small and slim shape !


Cases requiring surgery

If the size of left chin and right chin is different
If central line is not correct and face is asymmetric
If the central line is not correct and has short chin
When only chin line is asymmetirc
If you have open bite
If your gum is exposed too much when smiling
When you need reoperation

What is facial asymmetry ?

Facial asymmetry means just one side of chin is more developed or jaw bone is crooked.

Everyone’s face or body always has asymmetry but if chin is severely crooked or degree of development is different between each side, this has to be corrected through treatment.

Facial asymmetry with protruded face
If central line of face is crooked and this is combined with protruded mouth and short chin.


Big chin facial asymmetry
Lower jaw is big and wide and asymmetry



Facial asymmetry

Only chin line contour is different


Cause of facial asymmetry

  • Inherited symptom
    One part of one’s face is less developed because of inherited deformity or tumor around temporomandibular joint. Also asymmetry of teeth caused by early tooth loss can cause facial asymmetry as one grows.
  • Acquired symptom
    When upper and lower jaw is misaligned or there is injury or malocclusion, facial asymmetry can occur. Facial asymmetry is sometimes caused by irregular life pattern or wrong habits, especially when one use just one side of jaw to chew food can cause facial asymmetry.


Facial asymmetry diagnosis process



3D CT
We measure size, position, thickness of bone and distribution or blood vessel or nerves.


Production of ST Model
We make an operation plan after producing ST model which is equal to actual facial structure.



Simulation
We make the best operation plan based on photos of facial bone and teeth occlusion, and then we use surgery simulation program for better surgery.



Surgical method of facial asymmetry

Mandible surgery
We perform surgery only on mandible and we resect jaw bone vertically and then move it backwards and then finish surgery with orthodontics.
This is performed after incising inner surface of mouth and there is two kinds of method. One is SSRO(Sagittal Ramus Osteotomy) and the other is IVRO(Intraoral Vertical Ramus Osteotomy).
face96

0 SSRO(Sagittal Splitting Ramus Osteotomy)
We separate back parts of lower jaw and move jaw bone backwards and then fix them with pin or wire.

Advantage Weakness
Stable adhesion is possible since cross section is wide There can be strain on temporomandibular joint
Since bone is fixed firmly period of tying mouth is short There can be nerve damage on certain parts
Early recovery of lower jaw bone
.
Surgery time takes longer than IVRO
If you get short chin surgery only SSRO is possible Perfect recovery of lower jaw can take longer time than IVRO

0 IVRO(ntraoral Vertical Ramus Osteotomy)
This method cut the back part of jaw bone vertically. Bones are fixed without medical pins.

Advantage Weakness
Since bone is not fixed there is low chance of temporomandibular joint disorder and pain 2 weeks is needed to tie mouth for 2 weeks since jaw bone is not fixed
There is almost no chance of nerve damage Physical therapy is needed for 1~2 weeks for recovery or lower jaw
Quick recovery is possible since surgery time is shorter than SSRO You can feel overlapped part of bone after surgery
Since there is no strain on temporomandibular joint, full recovery or lower jaw takes shorter than SSRO It is hard to be applied on short chin

Chin point operation
If the occlusion is normal and only chin point is slightly asymmetric, this can be corrected with chin point surgery.
But if the facial asymmetry is severe because of the jaw bone structure, it can be improved only by jaw correction surgery like two jaw surgery.
face24

Two jaw operation
Facial asymmetry is hard to be improved only with mandible surgery or chin tip surgery. Detailed surgery prcedure is determined according to severity of asymmetry and correction is necessary through 2 jaw surgery if the asymmetry is severe.
2 jaw surgery is involved with resection of upper jaw and adjustment of the inclination, and then 2 jaws are relocated.
