Outline of Final Research Achievements |
The CAD/CAM hybrid resin is widely used as a material for manufacturing a dental crown restoration by a dental CAD/CAM system, and is expected as an aesthetic restoration material having excellent mechanical properties. However, there is a problem that the restoration falls off due to lack of adhesive strength. In this study, therefore, atmospheric pressure plasma treatment or surface treatment using a primer was performed in order to improve the adhesive strength for the CAD/CAM hybrid resins. As a result, it was revealed that the primer containing methylmethacrylate had high adhesive strength.

Academic Significance and Societal Importance of the Research Achievements |
現在,CAD/CAM用ハイブリッドレジンの接着力を向上させることを目的として,接着面にシランカップリング剤を含有したプライマーを塗布することが表面処理として通法となっているが,補綴物の脱落が多数報告されるなど重大な問題となっている. 本研究成果は,メチルメタアクリレートを含有するプライマーがCAD/CAM用ハイブリッドレジンの接着にかなり有効であることを明確に示していることから,臨床家へ接着に関する重要な情報を提供するものであり,補綴物の脱落件数の減少に寄与するものと思われる.
