To evaluate the effects of airborne-particle abrasion with alumina particles or silicamodified alumina particles on the bond strength between zirconia and conventional MDP-based (Ph; Panavia F 2.0, Kuraray) or self-adhesive (SA; RelyX U200, 3M ESPE) resin cements.
Five surface treatments were evaluated: C = no surface treatment; AB = airborne-particle abrasion with alumina particles (BIO-ART Dental Supplies and Equipment); ABP = AB combined with MDP-based primer (Alloy Primer, Kuraray); SS = airborne-particle abrasion with silica-modified alumina particles (CoJet, 3M ESPE) combined with silane (RelyX Ceramic Primer, 3M ESPE); and SSP = SS combined with MDP-based primer. The surface roughness (Ra) of the airborne particle-abraded samples (n = 5) was measured by a contact profilometer (Mitutoyo Surftest SJ-401, Mitutoyo). Cylinders of the resin cements tested were bonded to the surface-treated zirconia. The microshear test was performed by the application of a load with a wire loop parallel to the adhesive interface until debonding of the resin cement cylinders. The microshear bond strength (μSBS) of the samples was measured before and after being subjected to thermocycling (TC; 5°C to 55°C, 60 seconds dwell time for 3,000 cycles; MSCT, Marcelo Nucci). One-way (Ra) and two-way (μSBS) analysis of variance followed by Tukey post hoc test (α = .05) were used.
The SS (Ph: 12.6 MPa; Ph-TC: 6.37 MPa; SA: 11.8 MPa; SA-TC: 9.37) and SSP (Ph: 10.4 MPa; Ph-TC: 5.82 MPa; SA: 10.4 MPa; SA-TC: 10.0) surface treatments produced the highest surface roughness values (P < .001). The SS samples achieved the highest immediate bond strength for both resin cements. However, after TC, SA resin cement associated with any surface treatment produced the highest bond strength values.
The self-adhesive resin cement promoted higher and more stable bond strength values when associated with a surface roughening method.
评估用氧化铝颗粒或硅改性氧化铝颗粒进行空气颗粒喷砂处理对氧化锆与传统的基于MDP（Ph；帕纳维亚F 2.0，可乐丽）或自粘结（SA；瑞速凝U200，3M ESPE）树脂水门汀之间粘结强度的影响。
评估了五种表面处理方式：C = 无表面处理；AB = 用氧化铝颗粒进行空气颗粒喷砂处理（BIO-ART牙科耗材与设备）；ABP = AB联合基于MDP的底漆（合金底漆，可乐丽）；SS = 用硅改性氧化铝颗粒（CoJet，3M ESPE）进行空气颗粒喷砂处理并联合硅烷（瑞速凝陶瓷底漆，3M ESPE）；SSP = SS联合基于MDP的底漆。用接触式轮廓仪（三丰表面粗糙度仪SJ-401，三丰）测量空气颗粒喷砂处理样本（n = 5）的表面粗糙度（Ra）。将测试的树脂水门汀圆柱体粘结到经过表面处理的氧化锆上。通过用平行于粘结界面的金属丝环施加负载直至树脂水门汀圆柱体脱粘来进行微剪切试验。在进行热循环（TC；5°C至55°C，保持时间60秒，循环3000次；MSCT，马塞洛·努奇）前后测量样本的微剪切粘结强度（μSBS）。采用单向（Ra）和双向（μSBS）方差分析，随后进行Tukey事后检验（α = 0.05）。
SS（Ph：12.6MPa；Ph-TC：6.37MPa；SA：11.8MPa；SA-TC：9.37）和SSP（Ph：10.4MPa；Ph-TC：5.82MPa；SA：10.4MPa；SA-TC：10.0）表面处理产生了最高的表面粗糙度值（P < 0.001）。SS样本对两种树脂水门汀都获得了最高的即时粘结强度。然而，在热循环后，与任何表面处理相关的SA树脂水门汀产生了最高的粘结强度值。
当与表面粗糙化方法联合使用时，自粘结树脂水门汀能促进更高且更稳定的粘结强度值。
