Outline of Research at the Start

歯科診療における接着は非常に重要である.特に材料自体が金属に比べて脆弱な審美治療に用いられるメタルフリー材料に対する最適かつ強固な結合は,長期に安定した予後を担保する上で極めて重要な要素である.本研究課題では従来のシランカップリング剤よりも高い疎水性を有する長鎖シランカップリング剤を用い,歯科で一般的に使用されているメタクリレートに比べて反応性の高いアクリレートを併用した表面処理剤を新規に作製し,新たな長期耐久性を得ることが可能な処理方法を創出することを目的としている.

Outline of Final Research Achievements

The addition of multifunctional acrylate monomers could improve the flexural properties of PMMA, and the bond strength between the resin with the addition of the acrylate monomer and CAD/CAM ceramic blocks was affected by the type and/or amount of added monomers. The bonding effects of silane coupling agents and acrylate monomers on the CAD/CAM materials differed depending on their respective additional agents, and their synergistic effects on the material specificity were also noted. On feldspathic glass ceramic, acrylate monomers were less effective and acted as inhibiting factors depending on the amount of addition. On lithium disilicate glass ceramic, differences in adhesive properties were observed depending on the type and concentration of silane coupling agents and acrylate monomers. On hybrid glass ceramics, bond strength tended to increase with the amount of acrylate addition.

Academic Significance and Societal Importance of the Research Achievements

従来のシランカップリング剤よりも高い疎水性を有する長鎖シランカップリング剤とラジカル重合の反応性が高く,特に光照射に対する重合性に優れたアクリロイル基を用いた表面処理剤を使用した材料表面の改質は,メタルフリー修復に使用されるCAD/CAM材料の種類によってその効果は異なるものの,重合体の可とう性を向上することも招来され,メタルフリー修復の良好な長期的予後に寄与する可能性が示唆された.
