摘要: 目的:研究不同表面处理方法对Kavo氧化锆底层材料与Noritake Cerabien饰面瓷结合强度的影响。方法:选择Kavo氧化锆陶瓷作为底层材料,随机分为4组,每组8个试件。A组为染色液浸泡着色+表面不喷砂;B组为染色液浸泡着色+表面喷砂;C组为不浸泡染色液+表面不喷砂;D组为不浸泡染色液+表面喷砂。4组底层材料采用粉浆涂塑法烧结饰面瓷后,使用材料试验机测试其剪切强度,采用SPSS10.0软件包对数据进行统计学分析。结果:采用喷砂处理的2组(B组和D组)材料,其剪切强度均高于未喷砂的2组(A组和C组),差异具有显著性(P<0.01);浸泡染色处理对剪切强度的无显著影响,A组与C组、B组与D组之间的差异无显著性(P>0.05)。结论:对Kavo氧化锆基底表面进行喷砂处理,可以提高基底冠与饰面瓷的结合强度;而浸泡染色则对两者结合力的强度无显著影响。

Abstract: PURPOSE: To investigate the effect of different surface treatments on the shear bond strength of zirconia substructure and veneering ceramic. METHODS: Kavo zirconia specimens were divided into 4 groups (each group contains 8 specimens) according to different surface treatments: Group A was pigmented by dipping presintered blocks in the coloring solution VITA LL5, and not treated with abrasion after firing; Group B was pigmented with the same solution and then dealt with abrasion; Group C was not treated by any methods and Group D was only dealt with abrasion. All the veneering ceramics were fired on the zirconia substructure by slip-casting technique and the shear bond strength of zirconia substructure and veneering ceramic were tested. The data was analyzed statistically with SPSS 10.0 software package. RESULTS: The shear bond strength of the abrasive-treated groups (group B and group D) was significantly higher than the other two groups, but no significant difference was found between pigmented-treated groups (group A and group C) and non-pigmented-treated groups (group B and group D). CONCLUSIONS: Abrasion can increase the shear bond between Kavo zirconia substructure and veneering ceramics while pigmentation has no significant effect on the bonding strength.
