This study aimed to compare the effect of acid etching, sandblasting, or silica coating on the micro-shear bond strength of dual-cured resin cements to computer-aided design and computer-aided manufacturing (CAD/CAM) glass ceramic materials. Feldspathic, lithium disilicate, and zirconia-reinforced CAD/CAM ceramics were divided into four groups: control group (C), no surface treatment; hydrofluoric (HF) group, 5% HF acid-etched; sandblasting (SB) group, abraded with 50 µm aluminum oxide (AlO) particles; silica-coated (CJ) group, abraded with 30 µm silica-modified AlO particles. Roughness values were obtained by using a profilometer. The cements were condensed on the surface-treated specimens and a micro-shear bond test was conducted. The ceramic material ( < 0.001) and surface treatment type ( < 0.001) significantly affected the micro-shear bond strength values. HF acid etching can be recommended for the surface pretreatment of feldspathic, lithium disilicate, and zirconia-reinforced CAD/CAM ceramics. Better bond strengths can be obtained with HF acid etching than with sandblasting and silica coating.
本研究旨在比较酸蚀、喷砂或二氧化硅涂层对双固化树脂水门汀与计算机辅助设计和计算机辅助制造（CAD/CAM）玻璃陶瓷材料之间微剪切粘结强度的影响。将长石质、二硅酸锂和氧化锆增强的CAD/CAM陶瓷分为四组：对照组（C），未进行表面处理；氢氟酸（HF）组，用5%氢氟酸进行酸蚀；喷砂（SB）组，用50 µm氧化铝（AlO）颗粒研磨；二氧化硅涂层（CJ）组，用30 µm二氧化硅改性的AlO颗粒研磨。使用轮廓仪获得粗糙度值。将水门汀凝结在表面处理过的试样上，并进行微剪切粘结试验。陶瓷材料（<0.001）和表面处理类型（<0.001）对微剪切粘结强度值有显著影响。对于长石质、二硅酸锂和氧化锆增强的CAD/CAM陶瓷的表面预处理，推荐使用氢氟酸酸蚀。与喷砂和二氧化硅涂层相比，氢氟酸酸蚀可获得更好的粘结强度。
