Abstract

IPS Empress<SUP>®</SUP> is an all-ceramic crown system which provides a color tone and light transmittance resembling those of natural teeth. However, because of the translucency of all-ceramic crowns, the color of the adhesive resin cements and the abutment teeth can affect the color of the final crowns.<BR>This study examined the effects of IPS Empress<SUP>®</SUP> on the layering technique and color of the adhesive resin cements on various background color by comparison and examination.<BR>The color difference from the standard color was calculated, and it was judged to have color appearance when ΔE*ab≤2.0.<BR>The conclusions were as follows:<BR>1. For A 2 background, the color appearance to standard color were obtained using translucent type cements VW and VB (Variolink).<BR>2. For Au background, the color appearance to standard color were all of translucent type cements, while for Pd background, opaque type cements YO (Variolink) insertion with better color appearance.<BR>3. For H background, using translucent type cements Tr (LA cement) containing dentin color tone and opaque type cements VO (Variolink) with lower values of lightness yielded ΔE*ab≤2.0 with color appearance.<BR>The above results suggested that appropriate intermediate cements used in the layering techniqueof IPS Empress<SUP>®</SUP> decrease the influence of the background color, achieving a color tone approximating the target color.
