Abstract
The electrodeposition (ED) of adhesive monomer on dental alloy surfaces has been investigated to improve the adhesion of dental resin to dental alloy. In this study, the relationship between the ED treatment conditions and bond strengths was investigated by FT-IR using an aromatic carboxylate monomer (4-methacryloxyethy1 trimellitic acid, 4-MET). As a result, when the 4-MET was electrodeposited on the alloy surfaces, its carboxylate group and double bond of methacry1 group were detected on the alloy surfaces. Effective treatment conditions for each alloy differed depending on the type of alloy ; in a solution concentration of 10% 4-MET, and treatment current of 10-100 mA/cm2, 15%-1〜100mA/cm2 and 20%-1〜5mA/cm2, the maximum shear bond strength was 9.4 Mpa for 12% Au-Ag-Pd alloy. Similarly, at 5〜20%-1 mA/cm2 it was 11.6 MPa for pure titanium.
