• Resumen

  • Purpose: This study aimed to compare the marginal fit of 2 kinds of metal-ceramic crowns-crowns cast from commercially pure titanium and Procera titanium crowns.

    Materials and Methods: Ten copings of each type were prepared, veneered with low-fusing porcelain, and bonded with glass-ionomer cement. Marginal fit was assessed before and after cementation, and the data were analyzed statistically.

    Results: There were significant differences among mean values of marginal fit between the groups. Cementation increases discrepancies in both groups.

    Conclusion: Casting titanium has resulted in the highest discrepancies in marginal fit of both groups.
