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.
Porcelain Laminate Veneers have shown promising results recently
when used as an alternative to metal ceramic restorations for the
anterior teeth. Long-term success for any restoration depends on the
marginal fit, because marginal gaps increase pl
aque accumulation
and causing periodontitis. The aim of this study was to Asses
marginal fit changes according to were curing the bond agent before
or after cementation.
