Evaluation and Comparison of the Vertical Marginal Discrepancy of Ni-Cr and Co-Cr Alloys Before and After Porcelain Firing: An in Vitro Study

Conclusions: Co-Cr alloy PFM restorations have double vertical marginal discrepancy compared to Ni-Cr alloy restorations but both the values can be considered within clinical acceptability range of the marginal discrepancy.
