摘要: 目的 研究不同粘接剂对烤瓷瓷面与金属托槽间剪切强度的影响。方法 40个烤瓷瓷面经打磨、氢氟酸酸蚀、冲洗干燥、硅烷偶联剂处理瓷面后,再根据使用粘接剂的不同分为A组:光固化复合树脂粘接剂、B组:单组份化学固化复合树脂粘接剂、C组:树脂改良型光固化玻璃离子粘接剂、D组:双组份化学固化复合树脂粘接剂。将40个金属托槽粘接于烤瓷瓷面,经水浴孵化24 h后测得样本剪切强度,并进行统计分析。结果 A组剪切强度大于其他组(P<0.05),C组剪切强度小于B组(P<0.05),D组与B、C组剪切强度差异无统计学意义(P>0.05)。结论 光固化复合树脂粘接剂可获得最大的剪切强度,树脂改良型光固化玻璃离子粘接剂对金属托槽与烤瓷瓷面的粘接效果欠佳。

Abstract: Objective This study aims to investigate the influence of different adhesive materials on the shear bond strength of metal brackets bonded to porcelain surfaces. Methods A total of 40 porcelain specimens were deglazed, etched, rinsed, dried, and treated with silane coupling agent. Then, the 40 porcelain specimens were divided into 4 groups. A total of 40 metal brackets were bonded to each group with the following 4 adhesive materials: light-cured composite resin(group A), one-component chemically cured composite resin(group B), resin-modified light-cured glass ionomer cements(group C), and two-component chemically cured resin adhesive(group D). All specimens were placed with surrounding air and then stored in an artificial saliva bath for 24 h. Shear bond strength was measured by an Instron universal testing machine. Statistical analyses were performed by ANOVA. Results The shear bond strength of group A was the highest among those of the others(P<0.05). Meanwhile, the shear bond strength of group C was lower than that of group B(P<0.05). No statistically significant difference was found between groups B and D and between groups C and D(P>0.05). Conclusion Light-cured composite resin can acquire the highest shear bond strength among those of the porcelain materials tested. Resin-modified light-cured glass ionomer cements were found unsuitable for use as adhesive to bond metal brackets onto porcelain surfaces.

Key words: shear bond strength, adhesive material, porcelain surface bonding
