To evaluate the shear bond strength of resin cements to zirconia treated with the selective infiltration etching technique (SIE).
Forty-seven zirconia specimens were prepared with a sequence of silicon carbide abrasives, cleaned in an ultrasonic bath. Three samples were separated for atomic force microscope (AFM) analyses (one nontreated for control, one sandblasted, and one selective infiltration etched) and the remaining were randomly distributed in four groups, according to the combination of surface treatment and resin cement: group 1a (sandblasting + Variolink II), group 1b (sandblasting + Panavia SA Plus), group 2a (SIE + Variolink II), group 2b (SIE + Panavia SA Plus). A composite resin cylinder (3 mm × 3 mm) was cemented to the zirconia surface, as per each group's specific protocol. After storing 24 hours in distilled water at 37°C, the specimens were tested for shear bond strength and the results were subjected to statistical analysis.
At 24 hours, the highest SBS values were observed in group 2b, where the SIE technique was used in conjunction with Panavia SA Plus. Lowest values were found in group 1a. Increased surface roughness was observed with SIE.
SIE significantly enhanced the resin bond strength to zirconia. However, cement selection was also an important factor, for both surface treatments tested.
Use of SIE method combined with MDP monomer containing resin cement can provide clinically acceptable bond strength between zirconia and resin cement.
评估经选择性渗透蚀刻技术（SIE）处理的氧化锆的树脂水门汀的剪切粘结强度。
用碳化硅磨料制备 47 个氧化锆样本，然后在超声浴中清洗。将其中三个样本用于原子力显微镜（AFM）分析（一个未经处理的作为对照，一个喷砂的，一个选择性渗透蚀刻的），其余的则根据表面处理和树脂水门汀的组合随机分为四组：组 1a（喷砂+Variolink II），组 1b（喷砂+Panavia SA Plus），组 2a（SIE+Variolink II），组 2b（SIE+Panavia SA Plus）。按照每组的特定方案，将复合树脂圆柱体（3mm×3mm）粘结到氧化锆表面。在 37°C 的蒸馏水中储存 24 小时后，对试件进行剪切粘结强度测试，并对结果进行统计分析。
在 24 小时时，在 SIE 技术与 Panavia SA Plus 联合使用的组 2b 中观察到最高的 SBS 值。在组 1a 中观察到最低的值。SIE 可显著提高表面粗糙度。
SIE 可显著提高氧化锆的树脂粘结强度。然而，对于所测试的两种表面处理方法，粘结剂的选择也是一个重要因素。
使用 SIE 方法结合含有 MDP 单体的树脂水门汀，可以在氧化锆和树脂水门汀之间提供临床可接受的粘结强度。
