Hello,
This is Apgujeong Yonsei Baro Dental Clinic, a Gangnam orthodontic clinic.
Today, we would like to introduce children’s orthodontic treatment with Invisalign First.
Although Invisalign First is an appliance designed for children’s orthodontics, if treatment is started at the right time, it may be possible to complete treatment through permanent teeth alignment in one course.
Some people occasionally ask,
“Why go that far for children’s orthodontics?”
However, at Apgujeong Yonsei Baro Dental Clinic, our goal is to provide treatment that can reduce the likelihood of needing orthodontic retreatment after the patient becomes an adult.
2022.09–2024.12
This child first visited us in September 2022 for children’s orthodontic treatment.
The concerns they wanted to improve were protruding teeth and spaces between the teeth.
2022.09
Viewed from the side, the upper teeth protrude considerably. The permanent canines had already begun to erupt.
2022.09
An overbite was visible, with the upper teeth covering the lower teeth so that the lower front teeth were difficult to see.
A midline discrepancy was also visible.
2022.09
The X-ray showed that, by making good use of the 18-month warranty period, this case could be completed through permanent teeth alignment.
2022.09
Most children who visit for orthodontic treatment do so because their front teeth are erupting crookedly due to insufficient space.
However, as in this patient’s case, there are also cases in which having too much space is the problem.
We decided to proceed with children’s orthodontic treatment using Invisalign First and began fabricating the appliances.
The first appliance was worn in October 2022. This is the patient’s condition after wearing all 31 appliances in the first set through June 2023.
23.12
The overbite remained,
23.12
but the flaring and protrusion of the front teeth had improved.
23.12
During this period, the remaining baby teeth fell out and the permanent teeth began to erupt.
From this point, we took a strategic rest period.
What is a rest period?
More extensive treatment is possible when the next set is fabricated after as many permanent teeth as possible have erupted.
The rest period lasted seven months, through December 2023.
Beginning in January 2024, the patient started wearing additional appliances from the second set.
24.05
There were 17 additional appliances.
This is the patient’s condition after wearing all the appliances in the second set through May 2024.
The overbite was corrected in the second set, but the midline still needed improvement.
24.05
The additional appliances were accompanied by elastics to adjust the molar bite relationship and midline.
The round metal rings are hooks for the elastics.
24.05
In the meantime, all the permanent teeth had erupted.
Because the midline still needed improvement, one more set of third appliances was used from June through October 2024.
The third set consisted of 16 appliances.
After waiting for the molar bite to stabilize, orthodontic treatment was finally completed in December 2024.
24.12
The improved midline achieved with the additional appliances is visible.
24.12
The teeth show a Class I bite relationship, and treatment is not completed if the bite is unsatisfactory.
24.12
Even with children’s orthodontics, retainers are equivalent to those used for adults.
Because the results are comparable to those of adult orthodontic treatment, retainer management must also be thorough, including both fixed wire retainers and removable retainers.
22.09–24.12
For pediatric patients treated with Invisalign First, the goal is a result comparable to adult orthodontic treatment.
22.09–24.12
Improvement in the flaring and protrusion of the front teeth
22.09–24.12
22.09–24.12
22.09–24.12
22.09–24.12
Once the protrusion of the upper teeth was corrected, the patient was able to close their mouth comfortably.
Invisalign First is not simply **a treatment that organizes the alignment of the teeth during childhood.
**By developing a treatment plan that takes growth and the timing of permanent tooth eruption into account,
one advantage is that treatment can continue with the goal of achieving a bite and tooth alignment comparable to those of adult orthodontic treatment.
Not every child will achieve the same result, but if treatment is started at an appropriate time and carried out strategically,
it may be possible to expect a stable long-term result beyond the limitations of children’s orthodontics.
In some cases, yes. When the timing of permanent tooth eruption and the severity of the malocclusion are favorable, there are cases in which treatment can be taken to the point where additional adult orthodontic treatment is not necessary.
Yes. As with adult orthodontic treatment, careful retainer management is very important for maintaining the treatment results stably.
