摘要:

目的 研究通用型粘接剂和树脂水门汀对氧化锆陶瓷剪切粘接强度和耐久性的影响。方法 氧化锆陶瓷烧结制作20 mm×10 mm×10 mm和10 mm×10 mm×10mm两种尺寸的试件,实验分为12组,将这2种试件分别采用不同的树脂水门汀(RelyX Ultimate树脂水门汀、Clearfil SAC自粘接树脂水门汀)和通用粘接剂(无粘接剂、Scotchbond通用粘接剂、Clearfil SE One粘接剂)在不同的储存条件(水浴、水浴+冷热循环)下进行粘接。测试剪切粘接强度,分析断裂形态。结果 水门汀(F=8.41,P<0.01)和粘接剂(F=30.34,P<0.01)对氧化锆剪切粘接强度的影响有统计学意义;储存条件对剪切粘接强度的影响无统计学意义(F=1.83,P=0.18)。RelyX Ultimate树脂水门汀、无粘接剂、水浴+冷热循环储存时的剪切粘接强度最低(14.02 MPa±6.86 MPa),RelyX Ultimate树脂水门汀、Scotchbond通用粘接剂、水浴+冷热循环储存时的剪切粘接强度最高(54.12 MPa±8.37 MPa)。结论 通用型粘接剂可提高树脂水门汀对氧化锆的粘接耐久性。非自粘接的树脂水门汀如不使用通用型粘接剂则其粘接耐久性下降。

Abstract:

Objective To study the effects of universal adhesives and resin cement on the shear bond strength and durability of zirconia ceramics. Methods Zirconia ceramics were sintered into 20 mm×10 mm×10 mm and 10 mm×10 mm×10 mm specimens. The experiment was divided into 12 groups. The two types of specimens were bonded using two variants of resin cement (RelyX Ultimate and Clearfil SAC self-adhesive resin cement), universal adhesives (non-adhesive, Scotchbond universal adhesive, and Clearfil SE One adhesive), and storage conditions (water bath and water bath-thermal cycling). The shear bond strengths were tested, and the fracture morphologies were analyzed. Results The cement (F=8.41, P<0.01) and adhesive (F=30.34, P<0.01) exerted a significant effect on the shear bond strength of zirconia, whereas storage condition showed no significant effect on this property (F=1.83, P=0.18). The lowest shear bond strength (14.02 MPa±6.86 MPa) was exhibited by the group treated with RelyX Ultimate resin cement, non-adhesive, and water bath-thermal cycling, whereas the highest shear bond strength (54.12 MPa±8.37 MPa) was displayed by the group treated with RelyX Ultimate resin cement, Scotchbond universal adhesive, and water bath-thermal cycling. Conclusion Universal adhesives can improve the durability of the bonding of resin cement to zirconia. If non-self-adhesive resin cement is used without a universal adhesive, the durability of the bond will be greatly reduced.
