| Outline of Final Research Achievements |
Although mirror polished dental restorative zirconia is water repellent, we found that 1) there was improved hydrophilicity through with toothbrushing, and 2) excellent wettability was similarly attained when annealing above 673 K. Superior cell proliferation ability on annealed samples was possible as a pretreatment for implants. According to XPS analysis, the amount of carbon adsorbed on the surface was decreased through toothbrushing and annealing. That is, toothbrushing as well as annealing have the function of removing the carbon adsorbed onto the zirconia surface, so it was clarified that hydrophilicity was obtained.
