氧化锆核瓷处理与饰面瓷工艺对瓷/瓷结合强度的影响
Effects of surface treatments on bond strength of pressed and layered veneering porcelain to zirconia
摘要
Abstract
Objective:To evaluate the effects of surface treatments on bond strength of pressed and build-up veneering porcelain to zirconia.Methods:CAD/CAM Y-TZP blocks were fabricated and classed into 6 groups.Groups A 1 and B 1 received no treatment (as the control group),groups A2 and B2 received dye-penetrating technique,groups A3 and B3 were tribochemically silica coated.Then,groups A1 to A3 and groups B1 to B3 were veneered using build-up technique or lost-wax press technique respectively.The double-layered specimens were subjected to shear bond strength(SBS) testing.Data were statistically analyzed using one-way ANOVA and LSD test (α=0.01).The treated Y-TZP surface and the typical fractured Y-TZP surfaces were examined using a scanning electron microscope.Results:No matter which methods were used for treating Y-TZP surface,there was no statistically significant in the mean SBS values between the two veneering techniques.When using build-up veneering technique,tribochemically silica coating provided the highest SBS,while no statistically difference was found among the surface treatments of Y-TZP blocks for the lost-wax press technique groups.Conclusion:Dyeing and veneering techniques had no influence on bond strength of zirconia to veneering porcelain,while silica coating significantly improved the bond strength for the build-up veneering technique.关键词
