A comparison of bond strength produced by using three different metal surface treatment were evaluated using three different cements. The surface metal treatment were sandblast, electrochemical etching and chemical etching. The three cements used were ABC, Rely-a-bond and panavia EX cements. The following conclusions were obtained: 1. The tensile bond strength of enamel-resin metal joint with panavia EX resin has the best bond strength when the metal was chemically etched. 2. The debonding strength of the chemically etched joints were superior compared to that obtained with either sandblast or electrochemical etching.
使用三种不同的金属表面处理方法并结合三种不同的粘结剂来评估粘结强度。金属表面处理方法分别为喷砂、电化学蚀刻和化学蚀刻。使用的三种粘结剂分别是ABC粘结剂、Rely-a-bond粘结剂和Panavia EX粘结剂。得出以下结论：1. 当金属经过化学蚀刻时，使用Panavia EX树脂的牙釉质-树脂-金属接头的拉伸粘结强度最佳。2. 与喷砂或电化学蚀刻相比，化学蚀刻接头的脱粘强度更高。
