In a previous paper^<1)>, the principle of pitting corrosion and the factors which affect on the shape of the pits were studied and the retentive force of retainers using pitting corrosion were measured. The result showed that the metal (92% Ni, 6% Cr alloy for crown restorations) surface etched by this electrochemical corrosion provided strong attachment of a thermo-setting acrylic resin to the metal substrate. This report describes a modification of this method for clinical use. The results showed that this new procedure provided stronger retentive force to the metal for bridge restorations (84% Ni, 8% Cr, 5% Cu, 1% Mn alloy) than the procedure used in the previous experiment. An incisal tooth decayed was restored using this new method.
