| Outline of Final Research Achievements |
The effects of adhesion inhibiting factors on dentin and resin core surfaces, as well as the effects of a new MDP-containing cleaner and universal-adhesive resin as methods for removing adhesion inhibiter treatment for preventing de-bonding of CAD/CAM resin composite crowns. As a result, temporary cement components were effectively removed by agitation with the new cleaner, and the bond strength of the adhesive resin cement to dentin was significantly recovered. The bonding to the resin core significantly improved by using the new cleaner in addition to an air scaler cleaning or washing with water, same as dentin bonding. Furthermore, as a pre-treatment for bonding to the resin core, applying universal-adhesive resin eliminate the negative effect of adhesion inhibitor.

| Academic Significance and Societal Importance of the Research Achievements |
本研究結果により，CAD/CAM冠を装着する際には機械的除去に続き化学的処理を行うことで接着阻害因子を十分に除去すること，そしてレジンセメントを使用する前に支台歯側にアドヒーシブレジンを使用することが有効であるが明らかとなった．本研究を通じて得られたデータにより本邦で多く行われているCAD/CAM冠におけるトラブルを減少させることにつながり，メタルフリー補綴の普及にも寄与すると考える.
