| Outline of Final Research Achievements |
Effective functional monomers for dental metals differ for noble and non-noble metals. In this study, the surface properties after the airborne-particle abrasion were analyzed to determine how these properties affect the binding with functional monomers. The results showed that airborne-particle abrasion with alumina changes the surface of cast titanium. Multi-purpose primers have a valuable simplifying effect, because they can be used to bond a variety of prosthetic materials without the need for an in-depth knowledge of bonding. The results of this study showed that, for both the cast titanium and gold alloy, the multi-purpose primer may be used without any problems in conjunction with airborne-particle abrasion. The combination of airborne-particle abrasion with alumina and priming with multi-purpose primers can be recommended for bonding prostheses made of cast titanium or gold alloy with an acrylic resin.

歯を失った際に用いられる補綴装置の中でも接着ブリッジは支えとなる残存歯の削合を従来のブリッジと比較して非常に少なくできる利点がある。今後，金属アレルギーの問題からチタンの使用が増加することが考えられ，臨床現場で用いられる補綴装置の材料は多様化する。接着ブリッジは，接着に関する専門的な知識や煩雑な操作を必要とする場面が多い。本研究では補綴装置の多種多様な材料に対して，簡便で強固な接着を得るための術式を模索した。本研究成果は歯科の臨床現場において推奨できる接着方法の１つとして提唱できることが示されたものであったと考える。得られた成果は国内外に示すため英文学術雑誌や国際学会にて報告を行った。
