Highlights

Factors investigated in the selected articles included the sample size, type of restoration, die material,preparation criteria, veneering technique, cementation, method of measuring fracture resistance, method of measuring marginal accuracy, results of fracture and results of marginal accuracy
Conclusions.Based on the currently available scientific evidence, The zirconia veneering technique significantly influences the fracture resistance of zirconia-based crowns, the layering veneering technique crowns recorded the highest failure loads, while the digital veneering technique crowns recorded the lowest failure loads, the combination
Recommendations.Before they can be recommended for daily application, the effect of newly introduced veneering techniques on the long-term stability of Y-TZP-based zirconia fixed dental prosthesis must be verified in well-designed, randomized clinical trials
