title: [Effect of electrochemical etching of alloy surface (Wiron 88 and Wironit) on the strength of alloy binding to enamel by the Microjoin cement].
abstract: One of the methods of "adhesive" preparation of the surface of the retention elements of AET bars and brides before their binding to enamel is electrochemical etching. The purpose of the method was creation on alloy surface of appropriate microretention for the fixing resin. The aim of the study was determination of the optimal conditions for etching of alloys (Wiron 88 and Wironit) as binding elements of AET constructions, and for checking the binding force of the Microjoin resin cement. The following etching conditions were accepted as optimal: for the Wiron 88 alloy (10 min, 2,7 V, 200 mA/cm2), for the Wironit alloy (12 min, 2,7V, 270 mA/cm2). The binding force of the alloys etched under optimal conditions to the enamel achieved with the Microjoin (Sci-Pharm-Madental) resin cement was measured also, using the Instron testing device. The movement velocity was 2 mm/min. The following strength of binding of etched alloys to enamel was measured: 195.7 kG/cm2 for the Wiron 88 alloy, and 128.6 kG/cm2 for the Wironit alloy.
