I want to get Invisalign treatment,

but since the appliances seem to be the same at every dental clinic,

I’m wondering if I should just go to the nearest one.

Is there any difference I should know about?

Hello, this is Lee Yang-gu, the chief director of ID Dental Clinic.

In most cases, orthodontic treatment with Invisalign uses authentic appliances, so the appliance itself can be said to be the same at any dental clinic.

Just like all orthodontic treatment, not only Invisalign, even if the appliances are similar or the same, the results can vary greatly from case to case.

This is essentially because the main parties responsible for orthodontic treatment are the dental clinic and the medical team in charge of the patient.

So when visiting a dental clinic for orthodontic treatment, it is important to consider the priorities you have in mind, and to carefully examine the clinic’s and medical team’s orthodontic experience, skill, and expertise in a comprehensive way.

In that regard, Invisalign treatment has indicators that are easier to check compared with other orthodontic treatments, which can be especially helpful when choosing a clinic.

Today, at ID Dental Clinic, we’ll explain the important points to consider when choosing a clinic for Invisalign treatment.

If it is an Invisalign clinic,

check the ‘Invisalign tier’ as well

Most orthodontic clinics that can provide Invisalign will have an ‘Invisalign tier.’

This is a tier system directly divided into 10 levels by the U.S. headquarters that developed and created the Invisalign appliance. The tiers are assigned every year.

These tiers are classified based on the number of Invisalign cases performed.

The highest tier currently, which requires the largest number of cases to achieve, is ‘Red Diamond,’ which requires more than 1,000 cases per year.

And in Korea, among single Invisalign orthodontic clinics, ID Dental Clinic is the one that has achieved this Red Diamond tier.

Since 2021, we have maintained it for four consecutive years, so we have overwhelming Invisalign orthodontic experience. (In fact, we were the first in Korea to receive Red in 2021.)

It would not be an exaggeration to say that ID Dental Clinic is currently one of the places that has performed the most Invisalign treatments in Korea.

Of course, we cannot say that the Invisalign tier is the absolute and definitive answer when choosing an orthodontic clinic.

However, it is also a clear fact that as countless cases accumulate, know-how is built, and that steadily accumulated know-how sharpens expertise, eventually proving itself through experience.

And in a way, the most objective indicator of that is the ‘Invisalign tier.’

Moreover, since the Invisalign tier can change every year depending on the level of Invisalign experience, you can use this information as a reference when choosing a clinic.

That is why, at ID Dental Clinic, we recommend looking not only at the tier for that year, but also at the history before that.

More important than that: ‘1:1 dedicated responsible treatment’

If you are considering Invisalign treatment, I think you are already paying close attention to 1:1 care.

At this point, it is better to look into the details a little more carefully. For example, many people usually check whether it is “1:1 care.”

Rather than that, check more specifically whether it is “1:1 responsible treatment” or “1:1 dedicated treatment.”

This is because orthodontic treatment takes longer than other types of treatment, so there is also a possibility that the medical staff may be changed during the treatment period.

In principle, orthodontic treatment differs in every aspect—from the treatment plan to the process and the results—depending on how well the medical team knows the patient and how deeply they understand the patient’s condition.

But if the medical staff is changed during treatment, the level of understanding that the new doctor has about the patient may end up being close to zero, which naturally makes patients feel uneasy and worried.

Like all orthodontic treatment, including Invisalign, there is no fixed answer like a mathematical formula.

In other words, depending on the medical team’s analysis, judgment, and ultimately their thinking, the answer can change at any time.

Of course, this does not often lead to treatment going wrong, but from this point on, patient satisfaction can vary.

Therefore, to prevent these issues in advance, ID Dental Clinic provides not only 1:1 treatment between the patient and the medical team, but also a structure in which the doctor in charge takes responsibility all the way through to the end of the orthodontic treatment.

And in this process, above all, with ID Dental Clinic’s Invisalign iTero, we quickly and easily obtain the patient’s full oral structure through a 3D oral scan, without the discomfort of the traditional rubber impression process.

This is also reproduced accurately through 3D simulation to create a customized orthodontic plan tailored only to the patient, while also providing a predicted view of the post-treatment outcome.

In addition, by reflecting the patient’s needs, ID Dental Clinic does its best at every orthodontic visit to deliver a more ideal treatment outcome.

We have explained the important points to look at when choosing a clinic for Invisalign treatment. What did you think?

Because Invisalign is so effective both aesthetically and for convenience, many patients also have doubts about its orthodontic effectiveness.

That is why patients often ask questions like, “Can Invisalign also correct my teeth?” when they are worried about severe orthodontic cases such as malocclusion, protrusion, or crowded teeth.

At ID Dental Clinic, we always confidently say, “There is no orthodontic case that Invisalign cannot handle.” That is how much experience we have.

I hope today’s information was especially helpful for those considering Invisalign treatment. Thank you.
