In their 20s. Came to us with the concerns, “My teeth are so crooked that I’m self-conscious about smiling in front of people” and “My toothbrush can’t reach some spots, so I’m worried about cavities and tartar.” Their bite was complex enough that other clinics had told them “wire braces are necessary” or “extraction is necessary,” but they were firm about wanting treatment with an inconspicuous appliance.

Treatment Details

We applied full orthodontic treatment (Comprehensive) with the clear aligner system Invisalign.
We carried out “lateral expansion,” widening the dental arch starting from the back teeth, to make space for the teeth without extraction.
We moved the teeth, which overlapped in complex ways, one by one to untangle them, forming a functional, beautiful U-shaped arch.

Treatment Duration & Sessions

Treatment period: About 2 – 2.5 years
Visit frequency: Once every 1.5–2 months

Cost

Total: ¥880,000–¥1,045,000 (tax included)
(Breakdown: Invisalign Comprehensive package)
*Because this case included high-difficulty recovery treatment, it is a full orthodontic treatment plan.

Risks & Side Effects

When moving overlapping teeth, gum recession or “black triangles” (gaps between the teeth) can occur.
Because treatment continues over a long period, staying motivated and strictly wearing the aligners for the required time (at least 20 hours a day) are key to success.
