Abstract
The purpose of this study was to investigate the AC impedance behaviors of TiN and ZrN coated dental abutment screw using arc-ion plating method (AIP). Abutment screw (Internal, Shinheung, Co) was prepared and used for various experiments; AIP coating and AC impedance test. TiN and ZrN film was coated on the abutment screw using AIP, respectively. The coated surface was investigated by field-emission scanning electron microscope (FE-SEM), energy dispersive x-ray spectroscopy (EDS), surface roughness tester at the screw top, flank and valley of abutment screw. The AC impedance behaviors of TiN and ZrN coated abutment surface was investigated by using potentiostat in 0.9% NaCl solution at 36.5±1℃. The surface of TiN and ZrN coated abutment screw showed the smooth surface without mechanical defects like a scratch formed by manufacturing process compared to non-coated abutment screw. Polarization esistances (Rp) of TiN and ZrN coated abutment screw were higher than those of non-coated abutment screw. The slope of Bode plot was -1 and capacitance characteristics of coated films appeared in coated abutment screw. The TiN and ZrN coating on the abutment screw by AIP method kept the stable coated film in corrosive oral environment.
