Determining the S-N Fatigue Curve for Lava Zirconium Dioxide

Abstract:

Zirconium dioxide is a material which over the recent years has been winning support among dental technicians and dentists. Due to its chemical composition and mechanical properties is can replace non-aesthetic caps or metal crowns. In their paper the authors have focused on the analysis of the material itself; zirconium dioxide under the trade name LAVA and assumed a single treatment technology developed together with dentists. The main objective of the study was to determine the S-N curve for the material that is zirconium dioxide. The next step for the authors was to perform a static three-point bending. Fatigue testing covered a group of 30 specimens which were then used to determine the S-N curve for zirconium dioxide. The authors determined the S-N curve thanks to which the dentists are able to predict the destruction of the construction element which presents all-ceramic substructure. In the lecture review and according to authors it is said that in the aqueous environment the values of stress are similar with the dry environment and are within 850 MPa.
