摘　　要：目的:测定试件经过喷砂、硅溶胶热处理及与硅烷偶联剂结合的表面处理后,三种树脂粘接剂与纯氧化铝贴面的剪切强度。方法:选取高纯度的α-Al_2O_3纯氧化铝试件30个,将其随机分为A(可乐丽菲露SACTM复合树脂粘接剂)、B(Vorilink N树脂粘接剂)、C(RelyXTM Unicem树脂粘接剂)三组,每组10个。与试件粘接,在恒温水浴37℃的环境下静置24 h后测试其剪切粘接强度。扫描电子显微镜下观察各试件粘接界面的破坏形式。结果:Vorilink N粘接强度为(18.37±2.11)、RelyXTM Unicem粘接强度为(9.98±1.22),SACTM树脂粘接材料粘接强度最好,为(25.91±2.97),显著高于Vorilink N树脂粘接剂和RelyXTM Unicem树脂粘接剂,差异具有统计学意义(P<0.05)。A组全部为混合破坏,B组出现了粘接剂的内部破坏,C组既有混合破坏也有界面破坏和粘接剂的内部破坏。扫描电镜图显示A、B两组的粘接断面上有很多树脂残留,C组表面相对光滑树脂残留很少。结论:不同树脂粘接剂对纯氧化铝试件的粘接强度有影响,SACTM粘接剂的粘接效果最好。Objective: The shear strength of three resin adhesives and pure alumina veneers was determined by sandblasting, silica hydrothermal heat treatment and silane coupling agent. After the surface treatment, the shear strength of three kinds of resin adhesives and pure alumina was determined. Methods: Thirty cases of the high purity α-Al 2 O 3 pure alumina specimens were randomly divided into three groups: group A (SACTM resin adhesive), group B (Vorilink N resin adhesive), group C (RelyXTM Unicem adhesive), with 10 cases in each group. After bonding with the specimen, the shear adhesive strength was tested after incubation at 37 ℃ for 24 hours. The failure modes of the bonding interface of each specimen were observed under scanning electron microscope. Results: The bonding strength of SAC resin adhesive was (25.91±2.97), which was the highest in the hree kinds of resin adhesives (P<0.05) and was higher than that of Vorilink N (18.37±2.11) and RelyXTM Unicem was (9.98±1.22)(P<0.05). Group A was mixed for all, Group B had internal damage to the adhesive. Group C had both damage and interface damage and internal damage of the adhesive. Scanning electron microscopy showed that there were many resin residues in the adhesive cross section of group A and B, the residual resin on group C was few. Conclusion: Different resin adhesives had an effect on the bonding strength of pure alumina specimens. The SACTM adhesive had the best bonding effect.
