Considering an orthodontic hospital

I'm considering an orthodontic clinic.
Could those who have undergone correction please share their opinions?
Should we make corrections at the university hospital?
I'm considering whether I should get braces at an orthodontic specialist dental clinic near my house.
Would there be a significant difference in costs if I do it?

And I feel like my jaw is misaligned.
I'm worried that the alignment might shift even after using a retainer post-treatment.
If I use the retention device, won't it still become misaligned?
