| Outline of Final Research Achievements |
The device based on the hypercardiac rate that we aimed to develop in this research is unprecedented in the world and will be an epoch-making treatment for sleep bruxism (teeth grinding and clenching during sleep).
In 2020, we planned to manufacture a hypercardiac detection device, and in 2021, we planned to create software to check the accuracy of detection results and to manufacture an inhibitory stimulus generator, but there was a problem in checking the operation before delivery, and measures were taken. Because of this, the delivery was postponed to FY2024, so instead of using separate devices to detect hypercardiac heart rate and generate inhibitory stimuli, we decided to use a single device to detect both hypercardiac heart rate and generate inhibitory stimuli. We have developed the system this year.

| Academic Significance and Societal Importance of the Research Achievements |
睡眠時ブラキシズム（睡眠中の歯ぎしりやくいしばり）は騒音による対人的な問題を起こすだけでなく，本人にも歯やあごに無理な力がかかり破壊的な影響をもたらすときもあります．しかし根本的な治療法は存在せず，対症療法的なものがほとんどで有効な対策の開発が求められています．
本研究では睡眠時ブラキシズム発生に先行して生じることが知られている心拍数の亢進から発生の前兆を検知し，発生を抑制する装置を製作しました．心拍亢進をもとにする装置は世界でも類例をみず，睡眠時ブラキシズムの画期的な治療法となるものです．
