    Effect of different resin adhesives on the bond strength and edge microleakage of IPS e.max CAD all-ceramic crown

      摘要
    • 摘要:
      目的比较采用不同树脂粘接剂对IPS e.max CAD全瓷冠粘接强度及边缘微渗漏的影响。
      方法共选取离体前磨牙63颗作为研究对象，常规制作IPS e.max CAD全瓷冠、抗剪切强度样本，按照树脂粘接剂的不同分为A组（21例）、B组（21例）、C组（21例），A组采用Duo-Link树脂粘接剂进行粘接，B组采用Variolink N树脂粘接剂进行粘接，C组采用Kerr NX3树脂粘接剂进行粘接，经过冷热循环、微渗透以及抗剪切强度实验，对3组的抗剪切强度和边缘微渗漏长度进行统计分析。
      结果A、B、C 3组抗剪切强度比较差异有统计学意义（P < 0.05）；3组间两两比较差异无统计学意义（P>0.05）。边缘微渗漏等级中，3组只出现0~3级，A组多为0级，B组多为0级和1级，C组多为1级和2级，3组差异有统计学意义（P < 0.05）；其中，A组与B组、A组与C组、B组与C组差异有统计学意义（P < 0.05）。
      结论Duo-Link、Variolink N、Kerr NX3三种树脂粘接剂应用于IPS e.max CAD全瓷冠的粘接强度及边缘微渗漏各有差异，其中Kerr NX3树脂粘接剂的抗剪切强度最高，且边缘微渗漏程度最轻，有较好的粘接和良好的边缘。

       

      Abstract:
      ObjectiveTo compare the effects of different resin binders on the bond strength and edge microleakage of IPS e.max CAD all-ceramic crowns.
      MethodsA total of 63 premolars were selected as the research objects.The IPS e.max CAD all-ceramic crowns and shear strength samples were routinely prepared, and divided into the A group (21 cases), B group (21 cases) and C group (21 cases) according to the different resin adhesives.The A group was bonded with Duo-Link resin adhesive, the B group was bonded with Variolink N resin adhesive, and the C group was bonded with Kerr NX3 resin binder.The shear strength and edge microleakage length among three groups were compared and analyzed using the hot and cold cycle, micro-osmosis and shear strength tests.
      ResultsThere was statistical significance in the shear strength among A, B and C groups (P < 0.05).There was no statistical significance in pairwise comparisons between three groups (P>0.05).Among the marginal micro-leakage grades, the 0 to 3 grades in three groups were found, the grade 0 was mostly in A group, the grade 0 and grade 1 were mostly B group, and the grade 1 and grade 2 were mostly in C group.The difference between the three groups was statistically significant (P < 0.05);The differences between A group and B group, A group and C group, and B group and C group were statistically significant (P < 0.05).
      ConclusionsThe bonding strength and edge microleakage of IPS e.max CAD all-ceramic crowns are different among the application of the Duo-Link, Variolink N and Kerr NX3.The cutting strength and edge micro-leakage of the application of Kerr NX3 are the highest and lightest, respectively, which has good bonding and good edges.
