 note = {All-ceramic restorations have been advocated for superior esthetics. The ability to blend an all-ceramic crown with its natural counterpart involves the size, shape, surface texture, translucency, and color. IPS Empress, IPS Empress 2 (IVOCLAR VIVADENT), and Procera AllCeram (Nobel Biocare) remain popular and had continued widespread use. The purpose of this study was to examine the influence of the color of the abutments and resin cements (Variolink II VOCLAR VIVADENT) on the final color of copings for three kinds of all-ceramic core materials: Empress, Empress 2, and Procera AllCeram. Variolink II Try-In pastes (5 shades: transparent, A1・white, A3・yellow, A4・brown, opaque white) were applied in a thin layer on to three kinds of all-ceramic copings. Copings were inserted in to each abutment (six kinds of die materials from the Empress system, gold-silver-palladium alloy, gold alloy) and the final color of the central part of the buccal surface was measured using a spectrophotometer. The L*a*b* colour space was used to obtain the color values. Empress had the greatest effect on the influence of abutment tooth color and cement color on the color of coping. Regardless of the color shades of the abutments and cements, the lightness values rose in the order of Empress, Procera, and Empress 2. Regardless of the copings and abutments, when opaque white cement was applied to the coping, the lightness value.},
