Dental zirconia can no longer be considered un-bondable to tooth tissue. In literature, an increasing number of papers indeed report on the bonding effectiveness of different luting techniques to zirconia. We aimed to disclose general trends in bonding to zirconia by systematically collecting zirconia bond-strength data. A search in PubMed and EMBASE revealed 1,371 bond-strength tests reported on in 144 papers. A macro-shear bond-strength protocol was most frequently used; it revealed significantly lower bond strengths and was less discriminative than the other test methods. Regarding luting technique, the combination of mechanical and chemical pre-treatment appeared particularly crucial to obtain durable bonding to zirconia ceramics. The cement choice was not revealed as a determining factor after aging conditions, as long as composite cement was used. Regarding test protocol, a tensile test appeared more discriminative, particularly when combined with 'water storage' aging.
牙科氧化锆不再被认为与牙组织不黏合。在文献中，确实有越来越多的论文报道了不同的黏结技术对氧化锆的黏结效果。我们旨在通过系统地收集氧化锆黏结强度数据来揭示氧化锆黏结的一般趋势。在 PubMed 和 EMBASE 中进行搜索，共发现 144 篇论文中报告了 1371 次黏结强度测试。宏观剪切黏结强度方案最常被使用；它显示出明显较低的黏结强度，并且不如其他测试方法具有区分性。关于黏结技术，机械和化学预处理的结合对于获得对氧化锆陶瓷的持久黏结似乎特别重要。在老化条件下，只要使用复合黏固剂，黏结剂的选择并不被认为是一个决定性因素。关于测试方案，拉伸测试显示出更高的区分性，特别是与“水储存”老化相结合时。
