This study evaluated the tensile strength of enamel-resin-metal joints formed with four adhesive systems for attaching resin-bonded FPDs. Groups of 10 cast alloy cylinders were blasted with 50 microns alumina, washed, and prepared for bonding according to the resin as follows: (1) Panavia Ex with no treatment, (2) Super-Bond oxidized for 2 minutes with potassium permanganate in sulphuric acid, (3) Conclude electrolytically etched, and (4) ABC conditioned with primer. The cylinders were bonded to etched human enamel and after 24 hours in water at 37 degrees C the tensile strengths of the joints were recorded. Joint failure was examined under a stereomicoscope and a scanning electron microscope. The results demonstrated that the adhesive system influenced the tensile strength and mode of failure of the joints.
本研究评估了用于附着树脂粘结固定局部义齿的四种粘结系统所形成的釉质-树脂-金属接头的拉伸强度。将10组铸造合金圆柱体用50微米氧化铝喷砂、清洗，并根据树脂按以下方式进行粘结准备：（1）未处理的Panavia Ex；（2）在硫酸中用高锰酸钾氧化2分钟的Super-Bond；（3）电解蚀刻的Conclude；（4）用底漆处理的ABC。将圆柱体粘结到蚀刻后的人牙釉质上，在37℃水中放置24小时后记录接头的拉伸强度。在体视显微镜和扫描电子显微镜下检查接头失效情况。结果表明，粘结系统影响接头的拉伸强度和失效模式。
