The Influence of Background Color to 3 All-ceramic System Core Materials
To study the influence of background color to 3 all-ceramic system core materials.The chromaticity value of all samples that were put on noble metal,Ni-Cr alloy,Hg-Ag alloy and resign background were measured with chromatism instrument,and chromatic aberration among groups were calculated.The chromatic aberration of EmpressⅡ samples on different background color could be distinguished by human eyes,but those of Alumina and Zirconium were unable to being distinguished.In conclusion,the influence of background color to Empress Ⅱ and In-Ceram Alumina of ALl were lager.When chosen as core material,noble metals should be covered to keep prosthesis from clinical color-transform.As background to In-Ceram Alumina of AL2,it was unnecessary for resin to be covered.In-Ceram Alumina of AL3,AL4 and In-Ceram Zirconium werent affected by background color.
