This is a set of 68 Invisalign aligners out of the 77 aligners created at the dental clinic, excluding ① No. 1, No. 4, No. 19, 20, 21 (20 and 21 were not used, and the patient moved to ②), ② No. 19/19, ③ No. 11/11, ④ No. 12/12, and ⑤ No. 14/14. These aligners were used by a 10-year-old child for open bite correction starting in May 2024. The patient primarily drank water while wearing the aligners. They were cleaned daily with brushing, but some have slight yellowing or staining. The dates of replacement are noted. The personal information on the bags will be removed with nail polish remover before shipping. Please note that these aligners are custom-molded to an individual's teeth and cannot be worn by others. These aligners may be helpful for: - Those considering Invisalign treatment - Dental hygienists who want to study Invisalign - Those who want to understand the progress of orthodontic treatment, such as dental students.
