中文摘要:
      目的:观察喷砂、酸蚀、二氧化硅水溶胶热处理等表面处理方法对纯氧化铝陶瓷贴面与树脂之间粘接强度的影响。方法:选择高纯alpha-Al2O3烧结的纯氧化铝陶瓷贴面样本30 个,将其随机分为A、B、C 三组,每组10 个。分别应用不同的表面处理方法与同一种树脂进行粘结,A 组采用单纯喷砂,B 组采用喷砂+ 二氧化硅表面处理+HF,C 组采用喷砂+ 二氧化硅表面处理+ 硅烷偶联剂,检测和比较各组的粘接强度。结果:C 组的粘接强度最大,为23.84± 0.74,明显高于A 组和B 组(P<0.05),而A 组和B 组的粘 接强度比较差异无统计学意义(P>0.05)。结论:单纯喷砂或二氧化硅水溶胶热处理与HF的联合使用对纯氧化铝陶瓷贴面与树脂之间的粘接强度无明显改善,而采用喷砂以及二氧化硅水溶胶热处理与硅烷偶联剂的联合应用可取得纯氧化铝陶瓷贴面与树脂间的最大粘接效果。
英文摘要:
      Objective:To observe the effect of surface treatment methods such as sandblasting, etching, silica sol water and heat treatment between the surface and resin paste on the bond strength of pure alumina ceramics.Methods:30 cases of high-purity α -Al2O3 sintered pure alumina ceramic veneer samples were randomly divided into group A, B, C, 10 cases in each group. Different surface treatments were applied with the same kind of approach resin bonded, group A was treated by pure san blasting, group B was treated by silica surface treatment plus HF, group C was treated by sandblasting plus silica surface treatment using a silane coupling + a crosslinking agent, the adhesion strength was detected and compared between different groups.Results:The bonding strength of group C was 23.84 ± 0.74, which was the strongest and significantly higher than those of group A and groupB (P<0.05), and no significant difference was observed in the bonding strength between group A and groupB (P> 0.05).Conclusion:Sand blast alone or silica sol heat water plus HF had no significant improvement in the bonding strength between pure alumina ceramic veneers and resin, but sand blast and silica sol heat water plus silane coupling agent could achieve the maximumbonding effect between pure alumina ceramic veneers and resin.
