Hybridization technique impacted color of ceramic veneered zirconia. This study examined color characteristics of different ceramics veneered zirconia upon different hybridized techniques.
120 zirconia specimens (0.8 mm thickness, 12 mm diameter) were prepared from 3-yttria-stabilized tetragonal zirconia polycrystalline and unintentionally veneered with Vitabloc Mark-II (Vm), IPS e.max CAD (Em), Vita-Suprinity (Vs), and Celtra-Duo (Cd), by CAD-bonded (Cb) versus CAD-fused (Cf) hybridization (n=15/group). CIE-Lab* color characteristics were determined for translucency parameter (TP), contrast ratio (CR), opalescence parameter (OP), and color difference (ΔEdiff). Microstructures were investigated with SEM and XRD. Analysis of Variance and Bonferroni comparisons were determined for significant differences (<0.05).
TP and OP were significantly higher, but lower CR and ΔEdiff for Vm and Em than Cd and VS. Cf hybridized technique significantly decreased TP and OP but increased CR and ΔEdiff than Cb, which amplified color alteration. Better TP and OP, with less CR and ΔEdiff, were achieved for zirconia veneering with either Vm or Em, compared to Vs or Cd, whether hybridized with Cb or Cf technique.
Different veneering ceramics and hybridized techniques significantly altered color characteristics of ceramic veneered zirconia. Zirconia veneering with either Vm or Em appeared to produce better translucence and opalescence, with less contrast and color alteration than veneering with either Vs or Cd. CAD-fused decreased translucency, opalescence, and intensified color alteration due to t→m transformation. Nevertheless, the color alteration of ceramics veneered zirconia still rendered an acceptable limit, except for both Vs and Cd upon Cf hybridization.

杂交技术会影响陶瓷贴面氧化锆的颜色。本研究考察了不同杂交技术下不同陶瓷贴面氧化锆的颜色特征。
用3 - 氧化钇稳定的四方氧化锆多晶体制备120个氧化锆标本（厚度0.8毫米，直径12毫米），并分别用维他灵二代（Vm）、IPS e.max CAD（Em）、维他 - 苏普林（Vs）和Celtra - Duo（Cd）进行无意贴面，采用计算机辅助粘接（Cb）和计算机辅助熔接（Cf）杂交技术（每组n = 15）。测定了CIE - Lab*颜色特征的透光参数（TP）、对比度（CR）、乳光参数（OP）和色差（ΔEdiff）。用扫描电子显微镜（SEM）和X射线衍射仪（XRD）研究微观结构。采用方差分析和Bonferroni比较法确定显著差异（<0.05）。
Vm和Em的TP和OP显著更高，但CR和ΔEdiff低于Cd和VS。与Cb相比，Cf杂交技术显著降低了TP和OP，但提高了CR和ΔEdiff，这放大了颜色变化。无论采用Cb还是Cf杂交技术，与Vs或Cd相比，用Vm或Em进行氧化锆贴面时，都能获得更好的TP和OP，且CR和ΔEdiff更小。
不同的贴面陶瓷和杂交技术显著改变了陶瓷贴面氧化锆的颜色特征。与用Vs或Cd贴面相比，用Vm或Em进行氧化锆贴面似乎能产生更好的透光性和乳光性，对比度和颜色变化更小。计算机辅助熔接由于t→m转变降低了透光性、乳光性并加剧了颜色变化。然而，除了Cf杂交时的Vs和Cd外，陶瓷贴面氧化锆的颜色变化仍在可接受范围内。计算机辅助设计/计算机辅助制造、颜色、对比度、杂交技术、乳光、透光性
