ABSTRACT
Objective:
To evaluate the effects of several kinds of surface treatment methods on the bond strength of zirconia prosthesis,and to provide references for improving the bond strength of zirconia prosthesis.Methods:
Sixty zirconia blocks(10 mm×10 mm×2 mm) were divided into 6 groups according to the surface treatmentmethods:
sandblasting,silica coating,Z-PRIME Plus,sandblasting+Z-PRIME Plus,sandblasting+silica coating,and silica coating+Z-PRIME Plus groups.The zirconia-resin specimens were fabricated using ScotchbondTM Universal;shear bond test was performed to detect the shear bond strength after treated with water storage(37℃) for 24 h by universal mechanical testing mechine;the fracture types were observed by stereoscopic microscope.One fracture specimen was randomly chosen from each group,and the morphology of the specimen was examined under scanning electron microscope.Results:
The shear bond strength of the specimen in Z-PRIME Plus group was higher than those in the other groups(P<0.05).The adhesive failure was predominantly observed in sandblasting,silica coating,sandblasting+silica coating and silica coating+Z-PRIME Plus groups.There were 4 cases of mixed failure in Z-PRIME Plus group and there were 8 cases of mixed failure in sandblasting+Z-PRIME group.No cohesive failure was observed in all the groups.The scanning electron microscope results showed that the fracture surface occurred on the resin-zirconia interface of the specimens in sandblasting group,Z-PRIME Plus group,and sandblasting+Z-PRIME Plus group.The silica-zirconia fracture of specimens occurred in silica coating group and silica coating+Z-PRIME Plus group.The silica-resin interface fracture of specimens partially occurred in sandblasting+silica coating group.Conclusion:
The application of Z-PRIME Plus can significantly improve the bond strength between zirconia and resin.
