A working professional who lives near Sangil-dong Station said this in the consultation room.

"Transparent aligners are appealing,

but some people say braces are better....

I just can’t decide."

Many of you may be up late searching because of a similar concern.

If you search online, there is so much information,

and some posts say

transparent aligners are better,

while others say

wire braces are more accurate.

It only makes things more confusing,

and you end up wondering what is actually right.

To start with the conclusion,

for these two methods,

the key is not "which is better,"

but "which is suitable for my teeth."

Example photos

The reason diagnoses can differ from clinic to clinic

also comes down to this difference.

Even for the same teeth,

the conclusion can change depending on

what aspect is given more weight.

In fact, studies comparing the two methods

have continued to be published.

Today, based on those research findings,

I will summarize three real differences

between transparent aligners and wire braces,

and explain which method is most suitable

for which type of patient.

| Chapter 1. The [accuracy] of tooth movement is different. | This is the most important difference.

Transparent aligners do not move teeth

100% exactly as planned by the computer.

According to a study by Dr. Kravitz published in the 2009 Journal of Orthodontics,

the overall tooth movement accuracy of transparent aligners

was about 41% on average.

What is especially difficult

is rotational movement.

Rotating round teeth like canines

has an accuracy of only about 36%

with transparent aligners.

Of course, as technology has improved,

accuracy has also increased.

Example photos of wire braces

Simply put,

transparent aligners

"apply force well to the crown of the tooth,

but moving the entire root is a bit difficult."

On the other hand, braces that move teeth with wires

have brackets firmly attached to the teeth,

so the roots can be adjusted

with precision.

The difference is especially large in complex cases

where many teeth need to be moved,

such as extraction treatment.

According to a study published in Nature Reports in 2025,

when extraction cases were treated with transparent aligners,

cases were reported in which the front teeth tilted inward

and the molars tipped forward.

That is why, in cases requiring extraction

or for protruding mouth correction,

most orthodontic specialists

recommend wire braces.

| Chapter 2. Transparent aligners are more advantageous for gum health and tooth roots. | Example of transparent aligners

This is a clear advantage of transparent aligners.

When undergoing orthodontic treatment,

a phenomenon called "root resorption," where the tip of the tooth root becomes slightly shorter,

commonly occurs.

Most of the time, this is not a clinical problem,

but in severe cases,

it can affect the lifespan of the tooth.

Transparent aligners are removed when eating

and also when brushing,

so the area around the teeth can be kept cleaner,

and because force is applied intermittently,

there are reports that root resorption tends to be less.

Unlike wire braces, where food can easily get stuck

between the brackets and the wire,

transparent aligners are removed for brushing,

which also helps with gum care.

However, these advantages apply only on the condition

that they are worn properly for 20–22 hours a day.

If they are left out for long periods,

these advantages disappear.

| Conclusion |

Transparent aligners and wire braces

each have their own strengths and limitations.

So rather than asking which appliance to choose...

what comes first is accurately understanding

what your teeth condition is like.

We compare the methods objectively

and provide guidance based on each patient’s case.

It does not have to be our clinic.

But when you receive a consultation,

make your decision at a clinic that explains

the differences between the two methods thoroughly.

Because these are teeth you will use for 10 or 20 years.
