Comparing Study on Translucency of Four Veneered Dental All-Ceramic Core Materials
This study aimed to compare the translucency of four veneered dental all-ceramic core materials,including IPS e.max Press,Zenostar,Lava Zirconia and Upcera Zirconia.All specimens were fabricated at 10mm in diameter and 1.0±0.01mm in thickness.The translucency of specimens was measured with color difference meter and measurements were statistically analyzed with SPSS 13.0.Experimental results showed that their translucency had significant difference,the order of relative translucency fiom high to low was IPS e.max Press >Lava Zirconia>Zenostar >>Upcera Zirconia.IPS e.max Press which has good optical effect may be preferable for restoring anterior tooth with higher translucent.As for relatively opaque posterior tooth,Upcera Zirconia may be advisable.
