To get best appearance of fixed ceramic restoration this study depend on comparing & analyzing the effect of different thickness of metal casting on the esthetic & appearance of final shape of metal ceramic units, thickness of metal can be changed by controlling the thickness of wax which is consider the base of the cast .
In this study use 30 samples divided into 3 equal groups which had different metal thickness(A,0.8mm) (B,0.5 mm) (C,0.3mm), after ceramic building and glazing all these samples compare as much as similar to the 2M unit of Vita Tooth Guide company ,this was done by the same examiner using a random blind test.
These groups analyzed between each other using an Independent t-test where it was significant between (A&B) &(A&C) where as it was non significant between (B&C).
