Outline of Final Research Achievements |
Patients with dysphagia often experience oral-phase disorders, for which palatal augmentation prosthesis (PAP) is created and utilized for rehabilitation. However, the process of manufacturing and adjusting the PAP relies heavily on experience. This study aimed to apply swallowing CT to the fabrication and adjustment of intraoral appliances. The investigation involved studying swallowing dynamics during saliva swallowing and while using the PAP, as well as examining marginal form. Swallowing CT with mucosal surface enhancement was used to determine palatal thickness and marginal form using a temporary PAP made of wax. Additionally, the use of a 3D printer allowed for the fabrication of an actual oral model from the data, enabling the production of a PAP using materials suitable for intraoral use.

Academic Significance and Societal Importance of the Research Achievements |
本研究は嚥下CTを口腔内補装具の作製・調整に応用することを目的に実施された.嚥下CT時に口腔の粘膜面造影を行いワックスを用いた仮PAPからその口蓋厚の決定と軟口蓋の可動部位の決定をすることが可能であった。また3Dプリンターを用いることでデータから実際の口腔模型を作製し現在口腔内に使用できる素材でPAPを作製することが可能となった。今回の研究ではPAPの作製までに6時間かかったが、長期に口腔内に入れることが可能な3Dプリンター材料が使用できれば短時間でPAPが作製でき、患者への利点が大きく社会貢献につながると考えられる。
