Outline of Final Research Achievements

It was found that when the smart dental cement was applyed electric current through Ti embedded in a non-conductive material, titanium oxide was generated at the anode interface and gas was generated at the cathode interface. The non-conductive element and cement can be separated by this gas generation. Therefore, it is considered that the design that apply electric current to the metal emdedded in a part of the non-conductive material is effective, and the possibility of developing a new implant attachment and detachment style was found.

Academic Significance and Societal Importance of the Research Achievements

非導電性物質とスマートセメントの通電剥離が可能なデザインの考案ができた。このデザインがインプラントの上部構造に応用できれば、インプラントに負荷をかけることなく定期的に容易に着脱可能となり、審美性や耐久性を考慮したデザインの幅が広がり、衛生面の向上も期待できる。
