| Abstract | ||
| Background: Ceramic is very essential in the science of dental biomaterials. successfully in dentistry zirconia restorations have been utilized because of their good mechanical properties and biocompatibility. Zirconia cores are generally veneered with porcelain duo to lack of translucency, this make restorations weaker by means of miss of the cohesion between veneering ceramic and core material, the goal of the present study to estimate the influence of core material (zirconia) and surface treatment up on fracture resistance of some ceramic material. Methods: Forty samples of zirconia were fabricated by (Computer adding design/Computer adding manufacture technique. Samples were split randomly for four groups depending on their surface treatment , each group contains 10 samples .Group Zirconia control: Samples without surface treatment (control group).Group Zirconia sand plast: Samples sandblasted with 50μm of AL2O3particles.Group Zirconia potassium hydrogen difluoride :samples etched with 70 mg concentration of potassium hydrogen difluoride .Group Zirconia Combination: samples sandblasted with 50μm of AL2O3particles and etched with70 mg concentration of potassium hydrogen difluoride. Scanning electron microscope at different magnification was used to detect the morphological alteration of the zirconia following surface treatment.2mm veneering ceramic was put on all samples. Then sintering and glazing. fracture resistance of all samples was measured by universal testing machine. Statistical test perfect utilizing SPSS software. Results: In (Zirconia Combination) group the data analysis manifested that highest mean of fracture resistance values was, while the lowest mean of fracture resistance values was for (Zirconia Control) and (Zirconia Sand Blast) groups. Conclusion: Due to the time constraints of this study, using of different surface treatments with Zirconia | ||
