Effects of core characters and veneering technique on biaxial flexural strength in porcelain fused to metal and porcelain veneered zirconia.

Purpose: The purpose of this study was to assess the impact of the core materials, thickness and fabrication methods of veneering porcelain on prosthesis fracture in the porcelain fused to metal and the porcelain veneered zirconia.

Materials And Methods: Forty nickel-chrome alloy cores and 40 zirconia cores were made. Half of each core group was 0.

Evaluation of shear bond strength between dual cure resin cement and zirconia ceramic after thermocycling treatment.

Purpose: This study was performed to evaluate shear bond strength (SBS) between three dual-cured resin cements and silica coated zirconia, before and after thermocycling treatment.

Materials And Methods: Sixty specimens were cut in 15 × 2.75 mm discs using zirconia.
