Non-Surgical Adult Underbite Correction: Is It a Skeletal or Dental Problem?

Non-surgical adult underbite correction: We determine whether it is a skeletal or dental problem based on “this.” (Sinnonhyeon Station Orthodontic Clinic)

Hello. I am Kim Han-gyeol, the representative director of Smile View Dental Clinic and a specialist in comprehensive dentistry with 16 years of experience.

Are you looking for an orthodontic clinic in Sinnonhyeon because of an underbite that you would like to correct without surgery?

Many people experience not only concerns about their appearance but also functional discomfort because their lower jaw appears prominent or their teeth meet in an inverted bite.

However, most hesitate to seek treatment because they believe that “underbite means double-jaw surgery.”

Over the past 16 years, I have designed the smiles of many patients, and I have always considered it important to create results that look most natural and harmonious with each individual’s face.

• Smile design that harmonizes with the face

• Comprehensive diagnosis by a specialist capable of providing integrated care, including orthodontics, laminates, and cavities

• Thorough explanations that take into account the concerns of patients who are afraid of treatment

Based on these principles, today I will answer, in a clear Q&A format, many of the questions people have about “non-surgical adult underbite correction.”

“Double-jaw surgery feels like too much of a burden… Is it really impossible to correct it with orthodontics alone?”

Many of you reading this may have the same concern.

To give you the conclusion first, not every underbite case requires surgery.

Conversely, not every underbite can be improved with orthodontics alone.

The most important thing is to “accurately diagnose your condition.”

Q1. Does an underbite always require surgery?

No. It depends on the cause.

An underbite can generally be divided into two types.

• Dental underbite: The position of the jawbones is normal, but the lower jaw appears prominent because of problems with the angle or alignment of the teeth.

• Skeletal underbite: The lower jaw itself is positioned forward because of a growth discrepancy between the upper and lower jaws.

Although they may look similar externally, the causes are different, so the treatment approach must also differ.

If the problem is dental, orthodontics alone may produce a sufficiently satisfactory result.

The role of a non-surgical underbite orthodontic clinic like ours begins with accurately distinguishing the underlying cause.

Q2. What is the “ 기준” for determining whether orthodontics alone is possible?

After making a detailed diagnosis of the patient’s condition, we primarily assess the following three criteria together to determine the feasibility and potential scope of non-surgical orthodontic treatment.

1. Degree of skeletal discrepancy

We measure the relationship between the upper and lower jawbones using X-rays (cephalometric radiographs).

If the skeletal discrepancy is not severe, we may plan treatment to compensate for the discrepancy through tooth movement alone, known as camouflage treatment.

2. Bite relationship of the front teeth

We check how far the lower front teeth project beyond the upper front teeth and whether there is sufficient space to move the teeth.

If the degree of the reverse bite between the upper and lower front teeth is mild and a normal bite can be created through tooth movement, the possibility of non-surgical orthodontic treatment is higher.

3. Range of tooth movement and prediction of facial changes

Considering the current tooth angles and the condition of the supporting bone, there are limits to how far the teeth can be moved safely.

Within this range, it is important to predict how naturally the face can improve—not only through bite correction but also through changes in the position of the lips—when the teeth are moved.

Q3. How does non-surgical orthodontic treatment improve an underbite?

Non-surgical underbite correction improves the bite and appearance by moving the “teeth,” not the “jawbones.”

The principle is to reduce the appearance of a prominent lower jaw by changing the tooth alignment—for example, moving the lower front teeth backward and the upper front teeth forward.

This is called “camouflage treatment.”

Of course, it is difficult to expect the dramatic skeletal changes possible with double-jaw surgery, which changes the position of the jawbones themselves.

However, changes in tooth position alone can soften the impression around the lips considerably, and improving the reverse bite may help address functional problems.

Accurate diagnosis and planning by an experienced dental professional are essential for a successful result.

Q4. What should I look for in an orthodontic clinic to avoid regret?

When choosing an orthodontic clinic to address a non-surgical underbite, you should look beyond simply which appliance or bracket system is used. Confirm how accurately the clinic diagnoses the condition and whether it honestly explains the possibilities and limitations of treatment.

Underbite correction is a complex treatment that requires consideration not only of tooth alignment but also of the relationship with the jawbones and the balance of the entire face.

• Do they have an in-depth understanding of various areas of dentistry in addition to orthodontics? (Specialist in comprehensive dentistry)

• Do they sufficiently explain the treatment plan, expected results, and limitations?

• Do they aim for a natural result that best suits my face?

It is important to carefully check these points and develop a treatment plan with a dental professional you can trust.

I believe the role of an orthodontic clinic is to help you find that path together.

I have also personally undergone various dental treatments, including cavity treatment, root canal treatment, and wisdom tooth extraction, so I understand dental fears better than anyone.

That is why I consider it especially important to carefully examine each patient’s condition, fully explain why the treatment is necessary and what results may be expected, and make decisions together with the patient.

I hope this article has been helpful to those looking for an orthodontic clinic near Sinnonhyeon Station.
