摘要： 目的:探讨不同低温等离子体处理时长对氧化锆粘接耐久性的影响。方法:制作24个Ⅰ类（10 mm×10 mm×2 mm）和80个Ⅱ类（3 mm×3 mm×2 mm）氧化锆陶瓷块,将试件平均分为4组,即空白对照组（A组）、喷砂组（B组）、等离子体处理60 s组（C组）和等离子体处理120 s组（D组）,将粘接完成的Ⅱ类氧化锆试件每组又分为冷热循环组和非冷热循环组。以扫描电镜（scanning electron microscope,SEM）、X射线光电子能谱仪（X-ray Photoelectron Spectroscopy, XPS）、原子力显微镜（atomic force microscope,AFM）和水接触角测试仪对氧化锆表面进行检测,计算剪切粘接强度。结果:C、D组的表面形貌无明显改变,粗糙度与A组相比无显著差异（P>0.05）,表面亲水性较A组显著提升（P<0.05）。B组表面凹凸不平,粗糙度较A组显著增大（P<0.05）,亲水性较A组显著提升（P<0.05）。对于非冷热循环组,B、C、D组的剪切粘接强度较A组显著提高（P<0.05）;对于冷热循环组,B组剪切粘接强度最高,D组次之,C组再次之,A组最低,各组间差异有统计学意义（P<0.05）。结论:增加低温等离子体处理时长可增强氧化锆粘接耐久性。

Abstract: PURPOSE: To investigate the effect of different low temperature plasma treatment time on bonding durability of zirconia. METHODS: Twenty-four pieces of Class Ⅰ(10 mm×10 mm×2 mm) and 80 pieces of Class Ⅱ (3 mm×3 mm×2 mm) zirconia ceramic blocks were produced. The samples were divided into 4 groups, and dealt with separately according to the following groups: blank control group (group A), sandblasting group (group B), plasma treatment group 60 s (group C) and plasma treatment group 120 s (group D). The finished Class Ⅱ zirconia samples were further divided into thermocycling group and non-thermocycling group. Scanning electron microscope (scanning electron microscope, SEM), X-ray photoelectron spectrometer (X-ray photoelectron spectroscopy, XPS), atomic force microscopy (atomic force microscope, AFM) and water contact angle tester were used to detect zirconia surface and calculate shear bond strength. RESULTS: The surface morphology of group C and D had no significant change, the roughness was not significantly different from that of group A (P>0.05), and the surface hydrophilicity was significantly increased compared with group A (P<0.05). The surface roughness of group B was significantly increased compared with group A (P<0.05), and the hydrophilicity was significantly increased compared with group A (P<0.05). For the non-thermocycling group, the shear bond strength of group B, C and D was significantly higher than that of group A (P<0.05). For the thermocycling group, the shear bond strength of group B was the highest, followed by group D, and then group C, and group A was the lowest (P<0.05). CONCLUSIONS: Increasing the duration of nonthermal plasma treatment can improve the bond strength of zirconia.
