The purpose of this study was to evaluate the effect of five primers [Super-Bond C&B Monomer (SB), Clearfil Ceramic Primer, Alloy Primer, M.L. Primer, and AZ Primer] and two undercoating opaque resins [Super-Bond C&B (S-opaque) and Ceramage Pre-opaque (C-opaque)] on the bonding of a resin composite veneering material to a ceria-stabilized tetragonal zirconia polycrystals/alumina nanocomposite (Ce-TZP/AlO). Disk-shaped specimens of Ce-TZP/AlO were sandblasted with alumina and primed. The undercoating opaque resins and resin composites were subsequently applied to the specimen, and then light cured. After 5000 thermocycles at 4°C and 60°C, shear bond strengths were determined. Data were analyzed using analysis of variance, Tukey-Kramer honest significant difference test, and Student test ( = 10, = 0.05). With the exception of SB/S-opaque, all S-opaque groups exhibited significantly higher bond strengths than C-opaque groups. The use of S-opaque resin is recommended when veneering frameworks made of Ce-TZP/AlO.
本研究的目的是评估五种底漆[超级粘结剂C&B单体（SB）、Clearfil陶瓷底漆、合金底漆、M.L.底漆和AZ底漆]以及两种底涂不透明树脂[超级粘结剂C&B（S-不透明）和Ceramage预不透明（C-不透明）]对树脂复合贴面材料与二氧化铈稳定的四方氧化锆多晶体/氧化铝纳米复合材料（Ce-TZP/AlO）粘结的影响。对Ce-TZP/AlO的圆盘形试样进行氧化铝喷砂处理并涂底漆。随后将底涂不透明树脂和树脂复合材料施加到试样上，然后进行光固化。在4°C和60°C下进行5000次热循环后，测定剪切粘结强度。使用方差分析、Tukey-Kramer诚实显著差异检验和Student检验（n = 10，α = 0.05）对数据进行分析。除了SB/S-不透明外，所有S-不透明组的粘结强度均显著高于C-不透明组。当对由Ce-TZP/AlO制成的贴面框架进行贴面时，建议使用S-不透明树脂。
