Electrolytic etching of different alloys. 1. Weight loss of samples

: The adhesive fixed partial denture is a relatively new alternative in Dental Prostheses area, then it needs many studies in order to reach technique improvement. This work has the objective of studying the behavior of a copper-aluminium and two nickel-chrom dental alloys that were subjected to electrolytical etching with two experimental solutions and an electrolytic solution commented by TANAKA et alii, 1979. After weight-loss studies we can conclude that the alloy composition is a fundamental factor and to each alloy should be developed specifics electrolytical solutions.
