摘要:

目的探讨光照射强度对双重固化树脂粘接剂与硅烷偶联剂处理后的玻璃陶瓷间粘接耐久性的影响。方法选取Linkmax HV(LMHV)、Nexus 2(NX2)、Variolink Ⅱ HV(VLⅡHV)3种双重固化树脂粘接剂,使之与硅烷偶联剂处理的玻璃陶瓷粘接,接受800、310、80 mW·cm-2光强度照射后,制作成微剪切试件,然后在水储存1、90 d后,接受剪切实验。使用单因素方差分析每种粘接剂的数据。结果水储存90 d后,在所有光照射强度下,3种树脂粘接剂与玻璃陶瓷间的粘接强度降低,但光照射强度的减弱并没有加速其粘接强度的降低,相反接受310 mW·cm-2光强度照射的LMHV和80 mW·cm-2光强度照射的NX2获得了比800 mW·cm-2光强度照射条件更好的粘接强度。结论光照射强度的减弱对双重固化树脂粘接剂与硅烷偶联剂处理的玻璃陶瓷间的粘接耐久性没有影响。

Abstract:

Objective To evaluate the effect of light irradiation intensity on bond durability of dual-cured resin luting agents to silanized ceramics. Methods Linkmax HV(LMHV), Nexus 2(NX2), Variolink Ⅱ HV(VLⅡHV) as dual-cured resin luting agents were bonded to silanized GN-Ⅰ glass ceramics, and irradiated by 800, 310 and 80mW·cm-2 light intensity to form micro-shear test specimens. After 1, 90 d water storage, micro-shear bond strength of silanized resin/ceramic luting agent were measured. Data of each resin luting agent were analyzed by one-way ANOVA. Results 90 d water storage decreased significantly the bond strength of all test groups, and the weak of irradiation intensity did not deteriorate this reduction of bond strength of luting resin/cermaic, oppositely in which LMHV irradiated by 310 mW·cm-2 light intensity and NX2 irradiated by 80 mW·cm-2 showed the higher bond strength than that irradiated by 800 mW·cm-2. Conclusion The weak of irradiation intensity does not affect the bond durability of dual-cured resin luting agents to silanized ceramics.
