Abstract

The purpose of this study was to evaluate the possibility of the color adjustability of luting resin cements to all ceramic crown. In this study, Laminabond system (Shofu Inc.) of luting cements was used and the color adjustability on all ceramic crown of IPS-Empress system, which has a high translucency, was examined. Color difference (dE) and color coordinates (dL* and dC*) of ceramic sample (shade A1, A3, and A4) on metals (Pd-alloy and Au-alloy) to target color (ceramic sample+ ingot) were measured by means of a spectrophotometer (CAS-ID 1) with or without luting resin cements in-between. The luting cements tested were monotone cements (Opaque, Light, Orange, Red, Brown, and Blue) and mixed cements of Opaque and one of the others with the mixing ratios of 80: 20, 60: 40, 40: 60, and 20: 80. Opaque cement and mixed cements of Orange, Red, or Brown indicated efficient color adjustability to increase dL* and dC* and of dE from 1.5 to 3.5 for any kind of ceramic shade and metal for underlaying layer. In conclusion, mixed cementsat an adequate mixing ratio have color adjustability for the all ceramic crown of IPS-Empress.
