Five commercial dental silanes were evaluated in vitro as adhesion promoters bonding a luting cement to silica-coated titanium surfaces.
Titanium slides (n=20) were cleaned with alumina sand and then silica-coated with a special sand consisting of alumina particles coated with silica. The bonding of a resin composite cement (3M ESPE, Seefeld, Germany) to silica-coated and silanized titanium was evaluated by using the dental silane (RelyX Ceramic Primer) that belongs to the RelyX ARC cementing kit, and comparing it to four other dental silanes (Bisco Porcelain Primer, Cimara, ESPE Sil, and Pulpdent Silane Bond Enhancer). The resin composite cement stubs (n=8) were light-polymerized onto a silanized silica-coated titanium surface. The shear bond strength of the cement stubs was measured after dry storage and thermo-cycling 6000 times between 5 and 55 degrees C. The silanes and their reactions were chemically monitored by using Fourier transform infrared analysis.
Statistical analysis using ANOVA revealed that the brand of silanes and the types of storage condition differ significantly (p<0.005). The highest shear bond strength was obtained with RelyX ceramic silane in dry conditions (19.5+/-4.3 MPa), and after thermo-cycling (16.6+/-3.5 MPa). The lowest results were obtained using Pulpdent Silane Bond Enhancer, in dry conditions (7.8+/-2.2 MPa), and after thermocycling (5.3+/-2.4 MPa). The analysis showed that silanes had different pH values. Some differences were detected between the silanes and their reactions.
Dental silanes provide different bonding strengths and have differences in their pH, solvent system and silane concentration.
对五种商用牙科硅烷进行体外评估，以确定其作为粘结促进剂将粘结水门汀粘结到二氧化硅涂层钛表面的效果。
用氧化铝砂清洁钛片（n = 20），然后用一种由涂有二氧化硅的氧化铝颗粒组成的特殊砂进行二氧化硅涂层处理。通过使用属于RelyX ARC粘结套件的牙科硅烷（RelyX Ceramic Primer），并将其与其他四种牙科硅烷（Bisco Porcelain Primer、Cimara、ESPE Sil和Pulpdent Silane Bond Enhancer）进行比较，评估树脂复合水门汀（3M ESPE，德国塞费尔德）与二氧化硅涂层和硅烷化钛的粘结情况。将树脂复合水门汀短柱（n = 8）光固化到硅烷化的二氧化硅涂层钛表面。在干燥储存以及在5至55摄氏度之间进行6000次热循环后，测量水门汀短柱的剪切粘结强度。通过傅里叶变换红外分析对硅烷及其反应进行化学监测。
使用方差分析的统计分析表明，硅烷的品牌和储存条件类型存在显著差异（p < 0.005）。在干燥条件下，RelyX陶瓷硅烷获得的剪切粘结强度最高（19.5±4.3 MPa），热循环后（16.6±3.5 MPa）。使用Pulpdent Silane Bond Enhancer在干燥条件下（7.8±2.2 MPa）和热循环后（5.3±2.4 MPa）得到的结果最低。分析表明硅烷具有不同的pH值。在硅烷及其反应之间检测到一些差异。
牙科硅烷提供不同的粘结强度，并且在pH值、溶剂系统和硅烷浓度方面存在差异。
