shear bond strength of porcelain to a base-metal compared to zirconia core
statement of problem: recent clinical results for zirconia all-ceramic restorations have revealed that the fracture rate 6-15% of the zirconia framework is so low and the core of zirconia has high stability. however, chipping-off fractures of porcelain are the most common reason for failures of zirconia in the fixed partial dentures. objectives: the purpose of this study was to compare the shea...

متن کاملEffect of Laser Irradiation on Bond Strength of Zirconia Ceramic to Self-Adhesive Resin Cement
Background and Aim: Bonding of zirconia to resin cement is challenging, and the zirconia surface requires surface treatment to yield an acceptable bond strength. This study aimed to evaluate the effect of different surface treatments on the bond strength of zirconia to a resin cement. Materials and Methods: In this in-vitro experimental study, 60 zirconia discs measuring 12 mm in diameter an...
متن کاملBond Strength of Resin Composites used as Core Materials around Different Types of Fiber Posts
The purpose of this study was to evaluate the shear bond strength of two resin composites around different types of fiber posts. Twenty post specimens were prepared for three types of fiber posts. Posts were embedded in acrylic resin blocks with half of the post diameter exposed. The exposed portions of the posts were successively ground with silicon carbide paper until flattened flush with the...
