| Outline of Final Research Achievements |
In obstructive sleep apnea (OSA) patients, daytime symptoms such as sleepiness impair the work performance and lead to increases risk of motor vehicle accidents or lifestyle-related diseases. In Japan, continuous positive airway pressure (CPAP) treatment is covered by social health insurance for severe OSA, whereas oral appliances (OA) treatment is covered for mild OSA. However in CPAP therapy, patient acceptance and adherence are often low, thereby OA therapy is frequently effective even in severe OSA. Therefore patients often prefer OAs to CPAP treatment.
The purpose of this study is to develop the new evaluating system for sleep apnea using non-contacting analysis with infrared sensor. Furthermore development of the combined OA with mandibular and tongue advancement devices was another assignment. Development of the non-contact monitoring system for OSA with infrared sensor will simplify the evaluating system for detecting OSA patients and contribute to society in varied ways.

| Academic Significance and Societal Importance of the Research Achievements |
従来の睡眠検査は多くの電極，センサー等を被験者に貼付するため，身体の動きを拘束し，本来の睡眠状態を計測するには不向きであった．
本研究で用いた赤外線センサー(Kinect)は非接触，非拘束型の新しいOSAのスクリーニング検査法として，その用途は広く，睡眠検査の困難な介護老人養護施設の認知症患者のOSAの判定も可能と期待される．
また下顎・舌前突型OAの治療効果が周知されれば，現在歯科保険診療で適用される上下一体型OAだけでなく，新たなタイプの装置として保険導入が期待される．
