It was recently noted that there are
serious trials to develop dental materials used in the prosthodontics.
As a result of this development, some veneering ceramic systems
used in metal-ceramic crowns have been appeared. In view of the
major impo
rtance of marginal fit and its role in the success of
restoration it must be a study and evaluation of marginal fit for these
modern systems.
This research aimed to comparasion of marginal fit for metal ceramic
crowns using two types of veneering ceramic.
