title: Marginal fit of titanium metal-ceramic crowns.
abstract: OBJECTIVE
  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.
  
  
  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.
  
  
  CONCLUSIONS
  Casting titanium has resulted in the highest discrepancies in marginal fit of both groups.
