title: Evaluation of a chemical etching solution for nickel-chromium-beryllium and chromium-cobalt alloys.
abstract: Two chemical etching solutions were capable of providing micromechanical retention in two nickel-chromium-beryllium alloys and in a chromium-cobalt alloy. A resin matrix was used to verify the quality of etching on the metal surfaces. The chemical etching solutions created high microretentive surfaces in nickel-chromium-beryllium alloy but the chromium-cobalt alloy surfaces after etching were less retentive. Improved chemical etching technique should encourage expanded use of the resin-bonded retainers.
