【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(P0.05),C组剪切强度小于B组(P0.05),D组与B、C组剪切强度差异无统计学意义(P0.05)。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 to study the effect of different adhesives on shear strength between porcelain surface and metal bracket. Methods 40 porcelain surfaces were polished, corroded by hydrofluoric acid, washed and dried, and treated with silane coupling agent. According to the different use of adhesives, they are divided into group A: group B: group C, one component chemically cured composite resin, group C: group D, resin modified glass-ion adhesive: group D: two component chemical fixation Chemical composite resin adhesive. 40 metal brackets were bonded to the porcelain surface. The shear strength of the samples was measured after incubation in water bath for 24 hours, and statistical analysis was carried out. Results the shear strength of group A was higher than that of other groups (P0.05) the shear strength of group C was lower than that of group B (P0.05) there was no significant difference between group D and group B (P0.05). Conclusion the maximum shear strength can be obtained by the photocurable composite resin adhesive, and the effect of the resin modified glass-ion adhesive on the bonding between metal brackets and porcelain surface is not good.
