氧化锆不同表面处理方法对其与BeautiCem SA树脂水门汀粘接强度的影响
Effects of various surface treatments of zirconia on the Shear bond strength between the BeautiCem SA resin cements and zirconia ceramics
摘要
Abstract
Objective:To study the effects of various surface treatments of zirconia on the shear bond strength(SBS)between the BeautiCem SA resin cements and zirconia ceramics.Methods:Totally 100 zirconia specimens were made and randomly divided into 5 groups with 20 pieces in each group,the square surfaces of zirconia ceramics were respectively taken by no treatment(control group),zirconia-primer treatment(group ZB),sandblasting treatment(group SB),sandblasting plus zirconia-primer treatment(group ZSB),sandblasting treatment(group SD).The first 4 groups of zirconia ceramics were bond-ed to dentin with the BeautiCem SA resin cements,the SD group of zirconia ceramics were bonded to dentin with the Duo-Link resin cements.Each group was divided into two equal parts,respectively placed in 37℃constant temperature water bath for 24 h and 6 months,recorded as before aging and after aging.The SBS values were tested and the adhensive interface frac-ture modes were analyzed.Results:Compared to before aging,the SBS values of all groups decreased significantly after aging(P<0.05).Both before and after aging,the SBS values of control group or group ZB,SD were lower than those of group SB,ZSB(P<0.05).There were no significant difference in the SBS values among of control group,group ZB,SD(P>0.05),the same as between group SB and group ZSB(P>0.05).Conclusion:Sandblasting treatment could improve the SBS between the BeautiCem SA resin cements and zirconia ceramics,zirconia-primer could not improve that.The SBS values between the BeautiCem SA resin cements and zirconia ceramics were higher than those of the Duo-Link resin cements,with the zirconia ceramics sandblasting treatment not zirconia-primer treatment.关键词
