Hello

Today I’ll talk about Invisalign First clear aligners for children in Apgujeong.

Children’s clear aligners can help children look better earlier and can also affect self-esteem, so many guardians know they are a good option, but hesitate because they worry the child may need orthodontic treatment again later.

By completing pediatric orthodontic treatment first with Invisalign First and then reducing the likelihood of a second round of orthodontics when the child reaches the stage of a full permanent dentition, the chance of needing adult orthodontic treatment again later decreased significantly.

If the timing is right and all permanent teeth have erupted within the warranty period, both phases of treatment can be completed at once.

Today, I’ll share that kind of case.

Last spring, a 10-year-old child visited for orthodontic treatment.

The upper front teeth overlap the lower teeth a lot, showing a deep overbite.

Protrusion of the upper front teeth is visible.

The two remaining baby teeth are in crossbite.

Invisalign First treatment begins. The timing is good, and since a second phase of orthodontics is also possible, there is no reason not to proceed.

The first set consisted of 22 aligners. This is the condition after wearing all of the first set from March 2024 to September 2024.

The protrusion of the front teeth was corrected, but the deep overbite remained.

The arch shape became more beautiful.

To improve the overbite further, we moved on to a remake.

After wearing all 21 aligners in the second set in May 2025, treatment was finally completed.

The deep overbite of the front teeth was resolved, and the midline is well aligned.

The molar bite is a Class I relationship.

Because the result is comparable to adult orthodontic treatment, the retainer is also managed in a way similar to adult orthodontic treatment.

For overbite correction, it is better to use Vivera, but since the second molars are still erupting, we decided to make the Invisalign clear retainer, Vivera, after eruption is complete.

Now, let’s compare the before and after.

The total treatment period was 1 year and 2 months.

Improvement in the protrusion of the front teeth

The root parallelism is good, and there is no root resorption.

The speed of tooth movement is fast, and there are fewer orthodontic side effects, which are major advantages of pediatric orthodontics.

I hope this post helps parents who are considering orthodontic treatment for their children understand the treatment process.
