The objectives of this study were (1) to evaluate the bond strength of four resin materials with various chemical compositions following the manufacturers' instructions only and (2) to test their durability in dry and thermal aged conditions when they were bonded to zirconia ceramic. Four types of resin materials namely, Panavia F 2.0, Multilink, SuperBond and Quadrant Posterior Dense, were attached to the disc-shaped zirconia ceramics (LAVA, 3M ESPE) using polyethylene molds and polymerized accordingly after the ceramics were wet ground finished and ultrasonically cleaned. The specimens were randomly divided into two groups for ageing conditions. While the dry groups were tested immediately after attachment of the resin cement, the other specimens were subjected to thermocycling (x6,000, 5-55 degrees C). Bond strength results were significantly affected by the storage condition (p<0.001) and type of resin (p<0.001; analysis of variance). Panavia F 2.0 showed the highest bond strength results under dry conditions (9.6+/-4.1 MPa). When manufacturers' instructions of the resin cements were followed, no adhesion (0 MPa) was achieved on the zirconia after 6,000 thermal cyclings including Panavia F 2.0.
（1）仅按照制造商的说明评估四种化学成分各异的树脂材料的粘结强度；（2）测试它们在与氧化锆陶瓷粘结时在干燥和热老化条件下的耐久性。使用聚乙烯模具将四种树脂材料，即Panavia F 2.0、Multilink、SuperBond和Quadrant Posterior Dense，附着于圆盘状氧化锆陶瓷（LAVA，3M ESPE）上，并在陶瓷进行湿磨精加工和超声清洗后相应地进行聚合。将标本随机分为两组用于老化条件测试。在树脂粘结剂附着后，干燥组立即进行测试，而其他标本则进行热循环（6000次，5 - 55摄氏度）。粘结强度结果受储存条件（p<0.001）和树脂类型（p<0.001；方差分析）的显著影响。Panavia F 2.0在干燥条件下显示出最高的粘结强度结果（9.6±4.1兆帕）。当遵循树脂粘结剂的制造商说明时，在包括Panavia F 2.0在内的6000次热循环后，氧化锆上未实现粘结（0兆帕）。
