Effect of Helium Plasma Exposure on Wettability and Shear Bond Strength between the Zirconia Core and Feldspathic Veneering Ceramic: An In Vitro Study

Figure 6

The mean shear bond strengths (MPa) in the four experimental groups. Control: specimens with no surface treatment, Zr: plasma exposure on zirconia, FC: plasma exposure on feldspathic ceramic, Zr/FC: plasma exposure on both zirconia and feldspathic ceramic.
