This study evaluated the shear-bond strength of 11 luting cements from different material classes to manufactured pre-treated zirconia ceramics (Lava: 97% ZrO2, stabilized with 3% Y2O3). In addition, the influence of the curing method on shear-bond strength was investigated. The cements examined were one zinc-phosphate cement (Fleck's zinc cement), two standard glass-ionomer cements (Fuji I, Ketac-Cem), three resin-modified glass-ionomer cements (Fuji Plus, Fuji Cem, RelyX Luting), four standard resin cements (RelyX ARC, Panavia F, Variolink II, Compolute) and one self-adhesive universal resin cement (RelyX Unicem). The ceramic surface was sand-blasted with 100-microm alumina or tribochemically coated with silica. After bonding procedure, one group was tested after 30 minutes (Time I), the other group was stored in distilled water at 37 degrees C for 14 days and subsequently thermocycled 1000 times (Time II). Statistical analysis was performed by multifactorial ANOVA models with interactions. For multiple pairwise comparisons, the Tukey method was used. After sandblasting, the highest shear-bond strength was obtained for the self-adhesive universal resin cement at 9.7 MPa (Time I) and 12.7 MPa (Time II), respectively. When using the Rocatec system, the highest values were found for one of the resin cements at 15.0 MPa (Time I) and for the self-adhesive universal resin cement at 19.9 MPa (Time II).
本研究评估了11种不同材料类别的粘接剂与预制的预处理氧化锆陶瓷（Lava：97%ZrO2，用3%Y2O3稳定）之间的剪切粘结强度。此外，还研究了固化方法对剪切粘结强度的影响。所检测的粘接剂包括一种磷酸锌水门汀（弗莱克磷酸锌水门汀）、两种标准玻璃离子水门汀（富士I型、Ketac-Cem）、三种树脂改性玻璃离子水门汀（富士增强型、富士水门汀、RelyX Luting）、四种标准树脂水门汀（RelyX ARC、帕纳维亚F、Variolink II、Compolute）和一种自粘接通用树脂水门汀（RelyX Unicem）。陶瓷表面用100微米的氧化铝喷砂处理或进行二氧化硅摩擦化学涂层处理。粘接程序完成后，一组在30分钟后进行测试（时间I），另一组在37℃的蒸馏水中储存14天，随后进行1000次热循环（时间II）。采用具有交互作用的多因素方差分析模型进行统计分析。对于多个成对比较，使用Tukey方法。喷砂处理后，自粘接通用树脂水门汀的剪切粘结强度最高，分别为9.7MPa（时间I）和12.7MPa（时间II）。使用Rocatec系统时，一种树脂水门汀在时间I时的最高值为15.0MPa，自粘接通用树脂水门汀在时间II时的最高值为19.9MPa。
