Abstract:
Objective:To evaluate the effects of silane and universal adhesive alone or in combination on the micro-shear bonding strength(μSBS)between resin cement and resin nanoceramic(Brilliant Crios)and polymer-infiltrated ceramic network(Vita Enam-ic)materials.Methods:The two experimental material blocks were respectively prepared into 42 specimens with a size of 7 mm×6 mm×1 mm,and 50 μm alumina particles were used for sandblasting pretreatment under 0.2 MPa atmospheric pressure.The speci-mens were randomly divided into 6 groups,and the following surface treatment strategies were applied except for control group:si-lane,universal adhesive with silane(single bond universal,SBU);universal adhesive without silane(One Coat 7 Universal,OCU),silane and SBU,silane and OCU.Water contact angle measurements were used to observe the wettability of the 2 materials before and after silane treatment.The bonded specimens were prepared to test μSBS,which were analyzed by Weibull and the failure modes and were observed by stereo microscope.The morphology of the bonding interface was observed by SEM before and after si-lane treatment.Results:After the two materials were treated with silane,the water contact angle decreased(P<0.05).There was no significant difference of μSBS between the silane and control groups for Brilliant Crios(P>0.05),while the μSBS improved in the other experimental groups(P<0.05).Among the groups,silane+OCU group exhibited the highest Weibull modulus and charac-teristic strength.The μSBS of the experimental groups was increased compared with the Vita Enamic control group(P<0.05),silane+SBU group demonstrated the highest Weibull modulus and characteristic strength.Conclusion:Silane can improve the wetta-bility of the interface,and it alone improves the μSBS of Vita Enamic,but does not improve the μSBS of Brilliant Crios.The com-bined use of silane and universal adhesive enhances the μSBS between resin-ceramic composites and resin cement.
