Fig. 3From: Synergistic effect of wire bending and salivary pH on surface properties and mechanical properties of orthodontic stainless steel archwiresForce-deflection curves of two SS wires obtained by four-point flexural testing. The flexural Young’s moduli were the slope of the section on the curve indicated by a red line and the maximum force values are circled in red. Their corresponding values are given in the legendBack to article page
