Can non-surgical underbite correction really be done without surgery?

Orthodontic clinic recommendation

If you have an underbite,

can it improve with orthodontic treatment alone,

without surgery?

0

An underbite is often accompanied not only by concerns about appearance,

0

but also by difficulties with chewing and even jaw joint pain.

0

In fact, surgery can definitely bring a clear improvement.

0

However, because it is a procedure that involves cutting the jawbone, many people are looking for ways to avoid surgery.

I am Oh Su-hwan, a board-certified orthodontic specialist with 18 years of experience, certified by the Ministry of Health and Welfare. ^^

0

Including underbites, protruding mouth, crowded teeth, and front-tooth correction,

0

I have treated more than 4,000 cases of various kinds without a single medical accident.

0

Based on that experience, I can say,

0

non-surgical underbite correction is fully possible depending on the patient’s condition.

0

If a treatment plan is created that considers not only tooth alignment but also the jaw joint, gum bone, and skeletal balance,

0

significant improvement can be achieved without bone surgery.

0

In the following post, I have summarized when non-surgical underbite correction is possible,

0

and what criteria to use when choosing an orthodontic clinic recommendation.

Can I also get non-surgical underbite correction?

To start underbite correction, it is important first to identify why the jaw developed that way.

0

Even if the appearance is similar, the underlying causes are broadly divided into three types.

0

  1. Maxillary underdevelopment – a case where the upper jaw has not grown enough, making the lower jaw appear relatively protruded

0

In this case, an "arch expansion device" is used to widen the upper jaw sideways.

0

This not only aligns the teeth but also adjusts the width of the upper jaw to balance it with the lower jaw.

0

0

  1. Mandibular overgrowth – a case where the lower jaw bone itself has grown a lot

0

In such cases, orthodontic treatment that moves the teeth overall backward is needed.

0

However, if the skeletal discrepancy is too large, surgery may need to be combined as well.

0

  1. Dental imbalance – a case where the lower teeth appear to protrude more than the upper teeth

0

The lower teeth can be moved backward to correct the bite and gently adjust the facial line.

0

As such, non-surgical underbite correction is not simply about straightening the teeth.

0

It is a precise treatment that changes the facial shape by adjusting the position and proportions of the jaw.

0

That is why I look at the patient’s dental model and a 3D analysis program together,

0

and show the patient a prediction of their before-and-after appearance.

0

Through this process, the patient clearly understands the possible changes and limitations.

Orthodontic clinic recommendation:

Choose a place like this

Underbite correction is a high-difficulty treatment that considers the balance of the entire face, the jaw joint, and even the gum bone.

0

Therefore, who creates the treatment plan and how it is managed are much more important than what device is used.

0

0

In particular, even though underbites may look similar on the surface,

0

the actual treatment plan can differ completely by just a tiny detail, so the first diagnosis is truly important.

0

That is why

0

(1) a board-certified orthodontic specialist certified by the Ministry of Health and Welfare directly diagnoses the case

0

(2) there is extensive experience with high-difficulty orthodontics such as underbites and protruding mouths

0

(3) 3D simulation or dental model analysis is used during diagnosis

0

(4) the attending doctor does not change midway and is responsible for every stage of treatment

0

(5) detailed adjustments to the orthodontic plan are made at every regular checkup

0

You should choose an orthodontic clinic based on these criteria so you can steadily achieve results according to plan.

0

When I recommend an orthodontic clinic to acquaintances, I also tell them to look at the criteria above.

0

Orthodontics is a long-term project.

0

No matter how good the plan is, if the direction shifts midway through treatment, it is difficult to achieve a satisfying result.

0

That is why we base our care on customized diagnosis for each patient,

0

check progress every month, adjust the plan, and continuously share that process with the patient.

0

Non-surgical underbite correction can also succeed only when supported by this kind of precise diagnosis and management.

0

So rather than focusing only on equipment or cost, I hope you will choose based on people-centered care.

"Do I really have to undergo surgery?"

0

The answer to that question can only be known accurately after a diagnosis.

0

But what is clear is that there are many cases that can improve sufficiently with non-surgical underbite correction.

0

It is neither something that must always be avoided nor something that must always be done.

0

After accurately diagnosing the patient’s condition,

0

my treatment direction is to maximize the range that can be corrected with orthodontic treatment alone.

0

I hope you receive a trusted orthodontic clinic recommendation,

0

and meet a specialist who takes responsibility from diagnosis through treatment.

0

If you have any further questions, please feel free to contact us for a consultation.
