Fig. 2: Electrochemical behavior of activated pulsed electromagnetic device (pulse), compared with non-activated (control).

Electrochemical tests were conducted for analyzing the corrosion stability of pulsed and control healing abutments in artificial saliva. A Open circuit potential analysis, performed for 3600 s to evaluate the free corrosion potential of the material. B Nyquist diagram. C Bode plots showing variations in impedance as a function of frequency. D Potentiodynamic polarization curves. E Corrosion rate.
