The purpose of this study was to evaluate the color difference of specimens with the
variation of metal type and opaque thickness. Resin veneered specimens with the same
color were fabricated and evaluated by the CIE
L*a*b* system.
Specimens were divided into 4 groups as follows ;
Group P1; Resin with precious metal alloy, 0.1 §® opaque layer
Group P2; Resin with precious metal alloy, 0.5 §® opaque layer
Group B1; Resin with nonprecious metal alloy, 0.1 §® opaque layer
Group B2; Resin with nonprecious metal alloy, 0.5 §® opaque layer
The results obtained were as follows ;
1. L* value of group P1 was lower than that of group P2. There was
no significant differences in a* values among tested group.
2. Opaque thickness did not produce any significant differences of L*,
a*, b* value in the resin veneer groups on the base metal.
3. The ¡âE*ab value between P1 and P2 was 2.228 which is noticeable,
while the color difference between B1 and B2 was slight.
