摘要 目的评估不同实验条件下树脂水门汀与氧化锆瓷之间的剪切粘接强度(SBS)。方法使用计算机辅助设计与制作(CAD/CAM)设备切割并烧结制作6个边长为2cm的正方体氧化锆试件。按不同实验条件将8种双固化树脂水门汀分为13组(n=20):(1)Monobond N + Multilink N(MMN组);(2)Ivoclean + Monobond N + Multilink N(IMM组);(3)Ivoclean + Monobond N + Multilink N[无喷砂,IMM(ns)组];(4)Tetric N-Bond Universal + Multilink Speed(TUM 组);(5)Multilink Speed(MLS组);(6)Z-Prime Plus + TheraCem(ZPT组);(7)Z-Prime Plus + Duo-Link(ZPD 组);(8)SingleBond Universal + RelyX U200(SRU组);(9)RelyX U200(RXU组);(10)Single Bond Universal + RelyXUltimate Clicker(SRU 组);(11)OptiBond Versa + Kerr NX3(OVK 组);(12)Clearfil Universal Bond +Clearfil SAC(CUS组);(13)Clearfil SAC(SAC组)。将每组树脂水门汀自混合注入透明模具并将其无压力置于氧化锆面后进行光照固化。所有试件在37 ℃水中存储24 h后进行SBS测试。采用SPSS19.0软件One-Way ANOVA(P<0.05)对SBS进行统计学分析。利用电子体视显微镜观察氧化锆端断裂界面。结果本实验中13 组树脂水门汀的SBS(单位:MPa)降序排列依次为:OVK(27.51 ±3.65)>IMM(27.28 ± 3.79)>SRC(26.77 ± 3.62)>CUS(25.36 ± 3.10)>TUM(25.22 ± 4.88)>ZPD(23.96 ± 6.25)>MLS(23.13 ± 2.74)>MMN(23.07 ± 3.71)>SAC(22.20 ± 3.59)>IMM(ns)(21.99 ±3.50)>SRU(19.19±2.27)>ZPT(18.62±2.08)>RXU(15.04±4.02)。结论(1)不同树脂水门汀的SBS具有材料依赖性;(2)在氧化锆表面进行喷砂处理、使用专用清洗剂或将通用型粘接剂作为底漆使用有利于提高树脂水门汀的SBS。 Objective To evaluate the shear bond strength(SBS) between resin cement and zirconia under different experimental conditions. Methods In present study,six cubic zirconia specimens with a side length of 2 cm were cut by computer aided design/computer aided manufacturing(CAD/CAM) equipment and sintered afterwards. According to different experimental conditions,eight kinds of dual. curing resin cements were divided into 13 groups,such as:(1)Monobond N + Multilink N(MMN);(2) Ivoclean + Monobond N + Multilink(IMM);(3)Ivoclean + Monobond N + Multilink N[no sandblasting,IMM(ns)];(4)Tetric N-Bond Universal + Multilink Speed(TUM);(5)Multilink Speed(MLS);(6)Z-Prime Plus + TheraCem(ZPT);(7)Z-Prime Plus + Duo-Link(ZPD);(8)Single Bond Universal + RelyX U200(SRU);(9)RelyX U200(RXU);(10)Single Bond Universal + RelyX Ultimate Clicker (SRU);(11)OptiBond Versa + Kerr NX3(OVK);(12)Clearfil Universal Bond + Clearfil SAC(CUS);(13)Clearfil SAC(SAC). Each resin cement was injected into a transparent mould after self-mixing,and put onto the zirconia surface without pressure when finally being light-cured(n = 20). The SBS test of the all specimens was performed after 24 hours of 37 ℃ water storage,and the results were statistically analyzed by One-Way ANOVA,SPSS 19.0 software(P<0.05). The fracture mode on zirconia surface was observed by electron stereoscopic microscope. Results The bond strength(MPa)of resin cements in a descending order was:OVK(27.51 ± 3.65)>IMM(27.28 ± 3.79)>SRC(26.77 ± 3.62)> CUS(25.36 ± 3.10)>TUM(25.22 ± 4.88)>ZPD(23.96 ± 6.25)>MLS(23.13 ± 2.74)> MMN(23.07 ± 3.71)>SAC (22.20 ± 3.59)>IMM(ns)(21.99 ± 3.50)>SRU(19.19 ± 2.27)>ZPT(18.62 ± 2.08)>U200(15.04 ± 4.02). Conclusions (1)The SBS of resin cements was material-dependent.(2)The SBS of resin cement could be improved by sandblasting,using a special cleaning agent or universal adhesive as a primer on zirconia surface.
