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.
