※Custom-made aligners have not been approved by the Pharmaceutical and Medical Device Law in Japan and
are not covered by the Relief System for drug side effects.
※In accordance with the "Q&A regarding Medical Advertising Guidelines" issued by the Ministry of
Health, Labor and Welfare based on the Medical Care Act, the following is the description to meet the
"four requirements for lifting restrictions."

1、Clarification that it is an unapproved drug, etc.
TSURU-KAME Aligners are not approved by the Pharmaceutical Affairs Law.

2、Clarification of acquisition route etc.
TSURU-KAME Aligners are the product of K. Mediplan LLC and are entirely manufactured in Japan.

3、Clarification of the presence or absence of domestically approved drugs, etc.
Various types and systems have been developed for mouthpiece-type orthodontic devices (aligner
orthodontic devices).
Mouthpiece-type orthodontic devices similar to TSURU-KAME Aligners are sold in Japan, and some of them
have been approved under the Pharmaceutical and Medical Device Law in Japan, but TSURU-KAME Aligners
are custom-made orthodontic devices manufactured for each patient and are not marketable, so they do
not fall under the category of medical devices under the Pharmaceutical and Medical Device Law.
Additionally, although the TSURU-KAME Aligners are designed by a Japanese nationally qualified
dentist, they are manufactured by robots, so they do not fall under the category of orthodontic
devices under the Dental Technicians Law.

4、Clarification of information related to safety in other countries
TSURU-KAME Aligner is a treatment system that has been used in over 8,000 cases worldwide.
Other than the risks associated with orthodontics, there are no reports of serious side effects
