【摘要】：为比较不同表面处理剂对树脂-遮色瓷结合强度的影响,制作表面烤制有遮色瓷的金属基底5组,瓷表面酸蚀后,其中4组分别涂布RelyX Ceramic Primer(RCP)、Porcelain Bond Activator(与SE Bond Primer 1∶1混合使用)(PBA)、Shofu Porcelain Primer(SPP)、SE Bond Primer(SEP)四种表面处理剂,剩余一组作为空白对照。将5组试件与树脂粘接后测剪切强度,并分析、观察断裂模式。结果显示,所有实验组粘接强度均高于对照组;PBA组的粘接强度最高[(37.52±2.14)MPa],组内试件多为混合破坏(金瓷断裂和遮色瓷内聚断裂);SPP、RCP组高于SEP组(P0.05),组内试件多为混合破坏(粘接界面断裂和遮色瓷或树脂内聚断裂);SEP组和对照组内试件多为粘接破坏。因此,表面处理剂可提高遮色瓷与牙科复合树脂的粘接强度,二者粘接强度满足临床要求。
[Abstract]:In order to compare the effect of different surface treatment agents on the bonding strength of resin-covered porcelain, five groups of metal substrates with covered porcelain were made, the surface of which was etched by acid. Four kinds of surface treatment agents were coated with RelyX Ceramic Primerin Bond Activator (mixed with SE Bond Primer 1:1). The remaining group was used as blank control. The shear strength of 5 groups of specimens was measured after bonding with resin, and the fracture mode was observed. The results show that The bonding strength of all experimental groups was higher than that of the control group [37.52 卤2.14)MPa], and most of the specimens in the group were mixed failure (the breakage of metal-porcelain and cozy porcelain) was higher than that of the SEP group (P0.05N), and most of the specimens in the group were mixed failure (bonding interface). Most of the specimens in the SEP group and the control group were adhesive failure. Therefore, the surface treatment agent can improve the adhesive strength of the porcelain and dental composite resin, and the adhesive strength of both can meet the clinical requirements.
