Outline of Final Research Achievements

The aim was to evaluate the physical properties of shape memory hydrogel (SMG) for application of dental impression material in the use of maxillofacial prosthodontics. The SMG has the unique properties that it softens when heated, can maintain its shape when cooled, and returns to its original shape when reheated. Specimens were prepared by changing the polymerization initiator and the mixing ratio of the two monomers (SA, LA) of SMG. Physical properties were evaluated using a tensile test and evaluation of shape memory characteristics (fixation rate, recovery rate). The switching of the polymerization initiator of SMG to CQ enabled polymerization with the dental photopolymerization devices. It was confirmed that the shape memory property, an original characteristic of SMG.

Academic Significance and Societal Importance of the Research Achievements

顎顔面欠損患者の印象採得は,難条件下にも対応する適切な方法がないのが現状である.本研究成果から,形状記憶ゲル(SMG)を顎顔面補綴治療に適用することによって,顎欠損組織(アンダーカット,手術創面,易出血性腫瘤,筋皮弁)など複雑で脆弱な形態に対応する,ソフトでウェットな生体に優しい有効な印象材料として利用できる可能性が示唆された.さらにSMGの適用は,早期の経口栄養,治癒をも促進する新しい顎顔面補綴治療を確立できる可能性を有する.
