摘要： 目的:探讨烧结次数对不同方法染色的氧化锆陶瓷粘接性能的影响。方法:制作225个片状氧化锆陶瓷试样(10 mm×10 mm×1.5 mm),分为3组(n=75):浸泡染色组(A2色)、预成染色组(A2色)及对照组(白色)。每组随机分为5个亚组,分别烧结2、3、4、5、6次。将试样与自粘接树脂水门汀(Speed CEM)对位粘接,粘接面为直径1mm的圆形。试样经冷热循环2 000次后,扫描电镜和能谱仪进行氧化锆陶瓷表面形貌、成分分析,使用万能试验机检测粘接面微剪切粘接强度,体式显微镜观察树脂水门汀断裂模式。结果:随着烧结次数的增加,氧化锆陶瓷的微剪切粘接强度增加。经过6次烧结后,氧化锆陶瓷的微剪切粘接强度最高。浸泡染色组的氧化锆陶瓷微剪切粘接强度最高,且显著高于对照组。结论:浸泡染色的氧化锆陶瓷可获得较好的与树脂水门汀的粘接效果,烧结次数对氧化锆陶瓷的粘接性能有显著影响。

Abstract: Objective: To investigate the effects of repeated firings on the adhesion of zirconia with different coloring methods. Methods: Two hundred and twenty-five bar-shaped zirconia specimens (10 mm×10 mm×1.5 mm) were prepared and randomly divided into 3 groups: stained by immersion (A2 shade), pre-shaded (A2 shade), and the control group (white). Each group was further divided into 5 subgroups, which were sintered for twice, triple, four times, five times, and six times, respectively. The self-adhesive resin cement tubes (Speed CEM), with a diameter of 1 mm, were bonded on the specimen surfaces. After 2 000 thermal cycles, an universal testing machine was used to measure the micro-shear bond strength of the resin cements to zirconia. A stereo microscope was used to observe the fracture model. Furthermore, SEM and EDS were applied to obverse the surface topography and composition of the zirconia. Results: Along with the multiple firings, the micro-shear bond strength of the resin cement to the zirconia was increased. The specimens fired for 6 times showed the best adhesion property. The micro-shear bond strength of the zirconia stained by immersion was significantly higher than other groups. Conclusion: Zirconia stained by immersion showed better adhesion property. Moreover, the firing times affected the zirconia adhesion property.
