The complex caused by a protruding mouth often affects confidence and even daily life.

Because the mouth does not close easily, some people breathe through the mouth or develop the habit of covering the mouth when smiling.

At times like this, many choose Invisalign for protruding mouth to address the problem.

It is also well known for being clear and removable, which is why it draws interest.

So, what effects can be expected from improving a protruding mouth?

How long does treatment take?

The treatment period can vary greatly depending on each person’s dental condition and the degree of protrusion.

In general, mild cases that do not require extraction tend to take about 6 to 7 months.

However, in this type of orthodontic treatment, extraction may be involved, so a period of more than 2 years may be needed.

In particular, this case requires enough space to move the teeth backward.

For this reason, depending on the situation, permanent teeth may need to be extracted.

Then the removed space is closed while the front teeth are moved backward, which requires a considerable amount of time.

Patient cooperation also has a major effect on the treatment period.

You need to consistently wear the aligners for at least 20 to 22 hours a day for the treatment to finish within the expected timeframe.

Precise treatment process

It starts with establishing a detailed treatment plan through 3D simulation.

First, the condition of the teeth is accurately assessed through a 3D oral scan, and the movement path is simulated in advance using the Clean Check system.

During this process, you can preview the final result.

Then, during treatment, the aligners made for each stage are replaced at regular intervals to gradually move the teeth.

Because of the nature of this problem, controlling the angle while simultaneously intruding the permanent teeth into the gums is an important process.

Invisalign has the feature of being able to achieve complex movement without any additional devices.

During the middle stages, small protrusions called attachments are added so that force can be applied more precisely.

Through this, it may become possible to close the extracted space and move the teeth all the way to the roots.

Amazing improvement effects and the range of change

The effects of Invisalign for protruding mouth include not only changes in tooth alignment but also overall improvement in facial contours.

As the angle of the front teeth that previously protruded forward improves into the normal range, tension in the muscles around the mouth may be relieved.

As a result, the condition where the mouth is normally open can improve, and the mouth can close naturally.

You can also expect the effect of the nose appearing relatively higher as the mouth moves inward, along with a more slender facial shape.

In addition, symptoms such as a receding chin or drooping mouth corners often improve as well.

You can also expect significant improvement in functional aspects.

Even in cases where there was a temporomandibular joint disorder, the condition can stabilize and normal occlusion can be formed.

This leads to improved chewing function and overall oral health.

Precautions and key factors

Most importantly, patient cooperation is essential.

Loss of the appliance or insufficient wearing time can lead to an extension of the treatment period, so careful management is necessary.

In addition, thorough oral hygiene management is necessary so that cavities or periodontal disease do not occur during treatment.

If the shape of the teeth changes, the appliance may no longer fit and may need to be remade.

The experience and skill of the orthodontic medical staff also have a major effect on the results.

In these complex cases, accurate diagnosis, systematic treatment planning, and appropriate adjustments during treatment are necessary.

It is important to receive help from medical staff with sufficient clinical experience.
