Research Abstract |
Zirconia ceramics are recently used for esthetic prosthetic treatment. Yttria-stabilized zirconia can relieve a stress concentration or microcrack development on its surface, and that can be brought by martensitic phase transformation. This research project was examined the influence of martensitric phase transformation on the bond strength between zirconia and luting agent. As a results, the martensitic phase transformation on zirconia surface would increase the bond strength.
