Miniature Dentures with IC Chip for Denture Disaster Preparedness Limited to 100 free dentures for new users of free data storage

Fifteen years have passed since the Great East Japan Earthquake. Digital technology has begun to be used in disaster prevention and support for disaster victims. (Head office: Sapporo, Hokkaido; Representative Director: Akira Ikeda), which operates a dental laboratory, has produced a "miniature denture key chain" that can easily be used to request the production of new dentures by holding up a smartphone in the event of a disaster. A limited number of 100 units were distributed free of charge from April 1, 2026 (Wednesday) to new users of the "Denture Bank," which allows users to store their denture data digitally for free and immediately fabricate dentures outside of the disaster area in the event of a disaster.

A New Form of Disaster Preparedness

Oral health care in times of disaster should be a priority.

The year 2026 marks the 15th anniversary of the Great East Japan Earthquake. Awareness of disaster prevention is once again on the rise. One of the issues that has been attracting attention since the earthquake is disaster-related deaths. Aspiration pneumonia, which killed a large number of people, is caused by bacteria that have grown in the mouth, which has been unclean for a long time, and are gradually passed into the lungs. The presence or absence of dentures was also a factor, and one in five patients lost their dentures due to those that could not be taken out during the evacuation or due to falling and damaging them. Elderly people who were unable to eat properly for a period of time and whose physical strength had deteriorated became victims of the disaster. In the rapid support for disaster victims, priority is given to food, water, electricity, and toilets, while oral care tends to take a backseat. In the Noto Peninsula Earthquake of 2024, the use of digital technology began, such as the use of IC cards to confirm information on victims and the delivery of supplies.

The "mini dentures" are a good-luck charm for people in need. Mini Dentures as a Good Luck Charm

Omamori Dentures, which operates a dental laboratory in Hokkaido, has produced a miniature denture keychain that can easily be used to request a new denture by placing the denture information on an IC chip and holding it up to a smart phone. The keychains are available to new users of the free denture data storage service, "Denture Bank". The Denture Bank is a service that scans denture shape data in advance and stores it in the cloud on multiple servers in Japan and overseas for free. Scanning can be completed in about 30 minutes, and new duplicates can be completed in about a week using the stored data, or as soon as the next day in the event of a disaster. Duplication during normal times is charged for, but in the event of a major disaster, the service is provided free of charge, so there is no financial burden in the event of a disaster.

When a miniature denture measuring approximately 3.5 cm in diameter is held up to a smartphone, the name of the registrant, the name of the dental clinic, your denture data number (account number), and the reception phone number for the production request are displayed. If the denture is attached to the smartphone with the attached strap or the key that you carry in your daily life, you can immediately make a request for denture fabrication in case of emergency, and you can get back to your life with dentures as soon as possible. Some models allow you to call the displayed phone number by installing an application.

Chip with denture information on the back

I want a miniature of my dentures!

It all started when a man in his 60s living in Hakodate who uses the Denture Bank said, "I would be happy to have a miniature of my dentures. It would be even more interesting if the miniature dentures contained his data when he reorders dentures based on the data stored in the denture bank. We decided to commercialize the product because it was easy to wear and would help speed up support for disaster victims.

With a strap, it can be attached to smartphones as well.

We always have the safety and security of denture users in mind.

Since the Great East Japan Earthquake, we have been working to protect the health of denture users, and the Denture Bank is one of our initiatives. 18 dental clinics across Japan are currently members of the Denture Bank, which was launched nationwide in 2023. This is the first system in Japan to cooperate beyond the boundaries of prefectures and affiliated companies in the event of an emergency.

A representative said, "It is important to be prepared because you never know who will be affected by a disaster at any time. In dentures, which are often used by the elderly, we are promoting a system that allows dental clinics and laboratories to collaborate while effectively using digital technology, which is evolving at an accelerated pace. We hope that these humorous miniature dentures will serve as a good luck charm and reduce the number of disaster-related deaths."

The miniature dentures to be distributed free of charge this time are mass-produced to a standardized standard, but miniatures of one's own dentures are also available for production.
