What is a Protruded Mouth?

It refers to the state where the mouth protrudes more than the nose and jaw tip. In many cases teeth and gums are protruded as well.

Protruded mouth + normal chin :
bimaxillary protrusion surgery is done after simple tooth extraction.
Protruded mouth + short chin :
Since protrusion degree is different for upper and lower jaw, two-jaw surgery is required.
Protruded mouth + long chin :
Long face must be corrected at the same time.

Gum protrusion is severe.
Gummy smile with a lot of upper gum showing.
Infranasal depression is long or looks long.
Need to improve stubborn impression because of protruded mouth.
Orthodontic treatment was not effective.
Protrusion exceeds 4mm.

Protruded teeth: orthodontic treatment
Extract teeth with orthodontic treatment. It doesn’t require any change in alveolar bone.
Protruded gums:
bimaxillary protrusion surgery
Extract a tooth behind the canine tooth to secure space and move the gum bones backwards. It has a relatively fast recovery period of 1 week.
Minor case with protruded gums:
Extract a tooth behind the canine tooth and the empty space is filled and arranged with teeth lamination.
Complex protruded mouth:
two-jaw surgery
Two-jaw surgery is performed in the following cases: tooth extraction is not possible; protrusion is less than 4mm so typical bimaxillary protrusion surgery may create a nutcracker face; upper and lower jaw are protruding together; face looks long and gum is exposed too much etc.
Protruded lip with short chin :
Three-jaw surgery
Mandibular anterior segmental osteotomy and two-jaw surgery are performed together, so it requires good command of skill and wide surgical experiences. Protruded mouth + short chin: Protrusion degree of upper and lower jaw is normal and the chin is slightly short.

Specialty of Bimaxillary Protrusion Surgery at the Face Dental Clinic
Interdepartmental coordination between an oral and maxillofacial surgeon and an orthodontist makes orthodontics plus facial bone surgery possible. Based on wide clinical experiences, customized treatment is applied according to patients’ state so it secures the best result.
Exact diagnosis using 3D-CT
Every protruded mouth doesn’t require bimaxillary protrusion surgery. After exact diagnosis of facial bones and protrusion degree with digital X-RAY and 3D-CT scan, treatment is applied through simulation programs of V-CEPH, DOLPHIN etc.

Is orthodontic treatment alone able to correct mouth protrusion?
In case of protruded teeth, orthodontic treatment corrects mouth protrusion. But in most cases of protruded mouth, teeth and gums are also protruded, which requires bimaxillary protrusion surgery (teeth and gums must be pushed back together to have treatment effect). Two-jaw surgery may be needed according to types of protruded mouth, so accurate analysis is essential.
Does bimaxillary protrusion surgery require general anesthesia?
Bimaxillary protrusion surgery is done under general anesthesia but it doesn’t involve much bleeding. You can leave the hospital the next day and go back to everyday life after 5~7days. You’ll have no difficulty eating after 1~2 weeks. Orthodontics after surgery shortens treatment period to 6 months. (Typical orthodontics for protruded mouth takes about 2 years.)
What are the criteria for diagnosing bimaxillary protrusion surgery and two-jaw surgery?
If protrusion exceeds 4mm, bimaxillary protrusion surgery is performed which extracts a tooth and moves the gum bones to the empty space. If protrusion is less than 4mm, two-jaw surgery without tooth extraction is performed which pushes the whole protruded mouth area back. But there are no absolute criteria, so it may change according to the patients’ state and needs after diagnoses and consultation.
How long does the orthodontic treatment take in the case of protruded mouth which can be corrected with orthodontic treatment only?
It differs from person to person. Typical orthodontic treatment takes 1~2 years, and requires wearing a retainer for 1 year. A retainer doesn’t create discomfort since it’s removable. It keeps teeth in place after braces are finally taken off so wearing a retainer is highly recommended.
