Abstract：
UNASSIGNED: Our in vitro comparative study aimed to investigate the impact of thickness and tooth shade background on the translucency of highly translucent zirconia veneers.
UNASSIGNED: A total of 75 5Y-TZP zirconia veneers of shade A1 were fabricated with thicknesses of 0.50 mm (n = 25), 0.75 mm (n = 25), and 1.0 mm (n = 25). The translucencies were measured on composite resin teeth with shades A1, A2, A3, A3.5, and A4 using a digital color imaging spectrophotometer. Data were analyzed using ANOVA and post hoc Tukey\'s test (p < 0.05).
UNASSIGNED: The translucency values were optimal for the veneers placed over the substrate teeth with shades A1 and A2, regardless of the veneer thickness. Additionally, veneers with a thickness of 0.50 mm exhibited significantly higher translucency than those with thicknesses of 0.75 mm and 1.0 mm.
UNASSIGNED: Our study demonstrated that the translucency of the highly translucent zirconia veneers was influenced by both veneer thickness and tooth shade background. The optimal veneer thickness for achieving the highest translucency was 0.50 for the veneers with A1 and A2 shades placed over the substrate teeth.
UNASSIGNED: The optimal thickness for achieving the highest translucency of the highly translucent zirconia laminate veneers was 0.50 mm for the veneers with A1 and A2 shades placed over the substrate teeth. Clinicians and dental technicians could consider this when selecting materials for aesthetic restorations.

摘要：
■我们的体外比较研究旨在研究厚度和牙齿阴影背景对高度半透明的氧化锆贴面的半透明性的影响。
■总共制造了75个5Y-TZP氧化锆单板，厚度为0.50mm（n=25），0.75mm(n=25),和1.0毫米（n=25）。使用数字彩色成像分光光度计在具有阴影A1，A2，A3，A3.5和A4的复合树脂牙齿上测量半透明性。使用ANOVA和事后Tukey检验分析数据(p<0.05)。
■无论单板厚度如何，半透明值对于放置在具有阴影A1和A2的基材牙齿上的单板是最佳的。此外,厚度为0.50毫米的贴面比厚度为0.75毫米和1.0毫米的贴面表现出更高的半透明性。
■我们的研究表明，高度半透明的氧化锆单板的半透明性受单板厚度和牙齿阴影背景的影响。对于具有放置在基底牙齿上的A1和A2色调的单板,实现最高半透明性的最佳单板厚度为0.50。
对于具有放置在基底牙齿上的A1和A2色调的贴面,实现高度半透明氧化锆层压贴面的最高半透明性的最佳厚度为0.50mm。临床医生和牙科技术人员在选择用于美学修复的材料时可以考虑这一点。
