【摘要】：目的比较不同表面处理方法对氧化锆基底与饰面瓷之间的结合强度及结合界面微观结构的影响。方法将WIELAND氧化锆瓷块胚体烧结制成10 mm×5 mm×5 mm大小试件33个。将试件随机分为3组,每组11个。喷砂组在烧结前进行喷砂处理;处理剂组先喷砂处理,再烧结结合衬底瓷;对照组不做处理。3组基底瓷材料采用粉浆涂塑法烧结5 mm×5 mm×5 mm大小的饰面瓷。每组随机抽取1个基底瓷及双层瓷试件,采用扫描电镜、能谱分析方法,研究氧化锆底瓷与饰面瓷之间的结合情况。其余试件则通过电子拉伸机测试结合界面的剪切强度,并用SPSS17.0软件对实验数据进行统计学分析。结果喷砂组、处理剂组、对照组试件的剪切强度分别为(18.06±0.59)、(21.04±1.23)、(13.80±1.54)MPa,各组间差异均有统计学意义(P0.01)。结论氧化锆胚体烧结前喷砂处理能提高氧化锆基底冠与饰面瓷的结合强度,结合衬底瓷的应用能提高氧化锆基底冠与饰面瓷的结合强度。
[Abstract]:Objective to compare the effect of different surface treatment methods on the bonding strength and interface microstructure between zirconia substrate and finished porcelain. Methods WIELAND zirconia ceramic block embryos were sintered into 10 mm 脳 5 mm 脳 5 mm specimens. The samples were randomly divided into three groups. The sand blasting group was treated with sand blast before sintering, the treatment group was treated with sand blast first, and then the substrate porcelain was sintered. In the control group, 3 groups of substrate porcelain materials were sintered with 5 mm 脳 5 mm 脳 5 mm veneer porcelain by slurry coating method. One substrate porcelain and two layers porcelain samples were randomly selected from each group, and the results were analyzed by scanning electron microscope and energy dispersive spectroscopy. The bonding between zirconia bottom porcelain and finish porcelain was studied. The shear strength of the interface was measured by electronic tensile machine, and the experimental data were analyzed statistically by SPSS17.0 software. Results the sand blasting group, the treatment agent group, the sand blast group, the treatment agent group, the sand blast group, the treatment agent group, the sand blast group, the treatment agent group, The shear strength of the control group was 21.04 卤1.23 MPA, and the difference was statistically significant (P 0.01). Conclusion Sand blasting treatment before sintering of zirconia embryo body can improve the binding strength between Zirconia base crown and finished porcelain. The application of substrate porcelain can improve the bonding strength between zirconia substrate crown and decorative porcelain.
