Outline of Final Research Achievements

Palatal Augumentation Prosthesis (PAP) artificially treats tongue-palate contact failure during swallowing and vocalization due to organic or functional disorders of the tongue by attaching a floor device with a thickened palate. It is a prosthetic device that restores tongue-palate contact and is expected to restore swallowing and articulation functions. Among them, understanding the articulatory function is particularly difficult for healthy students, and has been an educational issue. In order to deepen the understanding of articulatory function, we improved a training program using a previously developed mouthpiece-type simulator for experiencing tongue dysfunction (MISLA). We verified whether students could actually experience dysarthria through practice. Furthermore, we verified whether the understanding of dysarthria was deepened.

Academic Significance and Societal Importance of the Research Achievements

日本は今後もさらに社会の高齢化は進んでいく傾向にある。その中で様々な障害に対応できる歯科医師育成が求められる。特に舌接触補助床(PAP)は多職種の中で歯科医師だけがおこなえる摂食嚥下・構音障害への対応であるが、依然その理解度は低い。その原因は健常者である学生が障害を体験できる機会が少ないためである。本研究により、構音障害について我々が開発した舌機能障害体験用マウスピース型シミュレータ( MISLA)によって学生が体験でき、理解を深められる実習プログラムを作成できた。これにより口腔リハビリテーションを担う歯科医師の増加が期待でき,我が国の構音障害患者のQOL向上を通じて社会への貢献が見込める。
