Abstract

IPS Empress<SUP>®</SUP>, an all-ceramic crown system, achieves natural tooth color appearance, however, because of the light transmission itself, abutment tooth color is influenced by the final restoration.<BR>This paper describes the effect of color blocking and changing through background color when using nine adhesive resin cements (50 and 100μm) and four ceramic ingots (TI, TII, OI and OII), which have different light transmission with a thickness of 1.5 mm in the middle coronal tooth portion, in the staining technique. The results were as follows:<BR>1. The effect of color blocking was significantly improved when only using JO (IMPERVA DUAL Opaque) and PO (PANAVIA 21 Opaque) cementation insertion.<BR>2. According to the increase in thickness of resin cement of all specimens, the value of L* tended to decrease as the luminosity decreased, the value of a* did not significantly change, and the value of b* tended to increase and there was a tendency to become more yellow.<BR>3. As the effect of color blocking, specimens using Oil ingot with low light transmission had the highest value. As the influence of thickness through the resin cementation, T I ingot with higher light transmissionhad a significantly improved value.
