Abstract
As we move towards a super-aging society, there is no doubt that the keywords for healthy longevity are improving immunity and basal metabolism, and dental treatment must help patients maintain their mental and physical health．However, 85.6% of people using dentures find it inconvenient when it comes to missing prostheses, and there are no shortage of medical com-
plaints．Looking at the reality of these dentures, regardless of insurance or self-funding, they do not provide high performance, comfort, and longevity．By acquiring the skills to provide dentures, we can create healthy and healthy elderly people, reduce wasteful medical costs, and gain social support from the public．
