Because of my protruding mouth,

my side profile is so stressful.

Surgery for protruding mouth is scary,

and braces feel like too much of a burden..

Is there no way?

There is a way.

Hello.

I am Oh Su-hwan, a certified orthodontic specialist recognized by the Ministry of Health and Welfare.

This year marks my 18th year in orthodontic treatment,

and among all areas, the one I have treated most often is protruding mouth correction.

(I also have patients who are flight attendants from Japan, Dubai, and Hong Kong.) Back to the main point,

Are you looking for a way to improve a protruding mouth discreetly and without surgery?

I would like to suggest Invisalign clear aligners.

When I say this,

some people respond,

'I heard that clear aligners have difficulty improving extraction cases or protruding mouths..'

That is true.

The clear aligners we commonly know are structured to wrap around the teeth like a cap,

so while they are excellent in terms of aesthetics, they have limitations when it comes to moving tooth roots.

But Invisalign is different.

Based on its own 3D simulation and precise design,

it is an orthodontic method that can effectively improve protruding mouth, underbite, and even spaced teeth.

Even protruding mouths that require extraction can be stably improved with Invisalign.

Next, I will explain the Invisalign protruding mouth treatment process in more detail,

so please focus for just 3 minutes.

Invisalign Protruding Mouth Treatment A to Z Protruding mouth surgery

Invisalign is made of a thin, transparent special plastic material,

so its biggest advantage is that it is barely noticeable during everyday life.

The basic treatment process is similar to regular orthodontics.

Problem analysis > appliance fabrication > periodically replacing appliances to improve the problem

The patient’s current condition is precisely analyzed with a 3D scan,

and based on those diagnostic data, all appliances up to the end of treatment are designed in advance.

After that, the appliances are periodically replaced according to the planned simulation,

gradually moving the teeth little by little.

Extraction + Invisalign protruding mouth improvement case Let me show you a case first.

It was a female patient who visited us saying, "My mouth looks protruded."

Even on the lateral X-ray before treatment, you can see that the teeth are tilted forward,

and that the mouth is protruding.

Surgery for protruding mouth felt scary, and she was also worried about recovery,

so after looking for a non-surgical option, she chose Invisalign.

The first premolars were extracted from the upper and lower jaws,

and the protrusion was gradually improved by moving the teeth backward through Invisalign.

You can see that the previously flared tooth alignment has returned to a normal position.

The total treatment period took about 20 months.

Comparing the before-and-after X-ray images,

you can see that the tilted front teeth have reduced to a normal angle, and the protruding mouth has naturally improved.

The lip line also closes smoothly and naturally,

and gingival display has been reduced, making the smile look softer as well.

After the orthodontic treatment was finished, laminate veneers were also added to refine the front tooth line and color.

However, it is not recommended for the following people Protruding mouth surgery

Invisalign can treat precise and diverse cases,

but it is not something I recommend for every patient.

☑️ Cases involving a structural problem of the jaw itself, or ☑️ People whose lifestyle makes it difficult to wear the appliance for more than 20 hours a day

In such cases, traditional orthodontic treatment with brackets and wires may actually be more stable.

An accurate judgment is important and should be made through an examination,

so I strongly recommend an in-person consultation to find the treatment most suitable for you. A protruding mouth is not something that must be solved only with surgery.

If an accurate diagnosis and plan come first,

Invisalign alone can bring about changes comparable to protruding mouth surgery.
