| Outline of Final Research Achievements |
This project aimed that development of laser assisted etching with acid solution and of new adhesive procedure on ceramics would achieve. Treatment with acid solution created deep porous surface on ceramic, whereas air abrasion formed shallow micro retentive structure on it. Concerning the adhesive strength between ceramic and resin luting material hydrofluoric acid etching achieved the highest strength value compared to the other groups. Both phosphoric acid etching and adhesive primer treatment also brought the higher adhesiveness compared to air abrasion, but either phosphoric acid etching alone or silane coupling treatment alone did not have higher bond strength to resin cement brought. Treating with phosphoric acid etching alone on ceramic detected the lowest strength value among all the test groups.
