Özet

The aim of this study is the investigation of the effect of blade designs used in the universal testing machine on the shear bond strength values. Three different zirconia framework ceramics (Zirkonzahn Translucent, Upcera Super Translucent, Rainbow Trans) and veneering ceramics suggested by their manufacturers (Zirkonzahn ICE Porcelain, Cerabien ZR Porcelain, Rainbow Porcelain) were subjected to shear bond strength tests with three different blade designs. Metal-ceramic (EOS Cobalt Chrome SP2 - GC Initial Porcelain) was used as a control group. A total of 90 samples (n = 10) for experimental group with zirconia framework and 30 samples of control group (n = 10) were prepared. Shear bond strength tests were performed with wire-loop design in the first group, notched-rod in the second group, and knife-edge chisel designs in the third group. Statistical analysis of the data was made by the Kruskal-Wallis test and followed by Conover's multiple comparison test. When the test results made with different blade designs were examined, no significant difference was found for zirconia samples. In the control group, a statistically significant difference was found between different blade designs. It was observed that the wire-loop group had significantly higher shear bond strength values compared to the notched-rod and knife-edge chisel groups. Used blade designs should be standardized in order to be able to evaluate the materials and methods used in the studies in the literature.
