Bond strength of etched-base-metal alloy to enamel using different etching techniques and cements.
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.
