| Outline of Final Research Achievements |
In zirconia-ceramic restoration, superior mechanical properties of Ce-TZP/Al are considered as an important factor of crown strength. In this study, we evaluated the fracture load of Ce-TZP/Al and Y-TZP ceramic crown frameworks to investigate optimum design of Ce-TZP/Al ceramic crown frameworks. A minimum thickness of 0.5 mm is recommended for Y-TZP ceramic crown frameworks in the posterior region. The Ce-TZP/Al crown frameworks of 0.3-mm thickness used in this study provide sufficient strength for clinical application. These results suggest that Ce-TZP/A ceramic crown framework can be thinner than a conventional Y-TZP ceramic crown framework.
