摘要： 目的:研究冷热循环对不同粘接剂与种植体支持的双端固定桥粘接力的影响。方法:3D打印制作种植体支持的钴铬合金双端固定桥共48个,分为复合树脂粘接剂(SAC)组即A组和树脂加强型玻璃离子水门汀 (Luting 2)组即B组,每个粘接剂组又按冷热循环次数分为0次(A1、B1)、2500次(A2、B2)、5000次(A3、B3)、10000次(A4、B4)等4个亚组。将基台固定于替代体上,完成固定桥的粘接后将所有试件浸泡于人工唾液中,37℃恒温水浴24h.A1、B1,A2、B2,A3、B3,A4、B4实验组分别冷热循环0次、2500次、5000次、10000次后进行拉伸试验测试粘接力(N)。结果:冷热循环前后SAC的粘接力均大于Luting 2 (P＜0.05);冷热循环2500次后两种粘接剂的粘接力下降不明显(P＞0.05);冷热循环5000次、10000次后两种粘接剂的粘接力均明显下降(P＜0.05)。结论:本实验条件下,SAC的粘接性能优于Luting 2。

Abstract: Objective: To study the effect of thermal cycling on adhesive force of different cements to the implant-supported fixed bridge. Methods: 3D printing production of Cobalt-Chromium alloy implant-supported fixed bridges were divided into group A (composite resin cement) and group B (resin modified glass ionomer cement). Both group had 4 subgroups: thermal cycling 0 times (A1 and B1), thermal cycling 2500 times (A2 and B2), thermal cycling 5000 times (A3 and B3), and thermal cycling 10000 times (A4 and B4). Abutments were fixed to the implant analogs, and then the fixed bridges were bonded to the abutments. All the specimens were immersed in artificial saliva with 37℃ water bath for 24 hours after curing. The tensile test was used to measure the adhesive force of different cements to the implant-supported fixed bridge after thermal cycling. Results: The adhesive force of SAC were higher than Luting 2 before or after thermal cycling (P<0.05). The adhesive force of both cements were not significantly decreased after thermal cycling 2500 times (P>0.05). The adhesive force of both cements were significantly decreased after thermal cycling 5000 and 10000 times (P<0.05). Conclusion: Within the limits of this study, the adhesive performance of SAC is superior to Luting 2.
