Evaluation of the Loading, Unloading, and Permanent Deformation of Newly Available Epoxy Resin Coated Ni-Ti Wires Using Self-Ligating Brackets

Table 1

Comparison of the mean force in Newtons between the regular and coated Ni-Ti round 0.016′′ wires at different deflection loads. The results are expressed as the mean ± SEM for 15 Ni-Ti wires. and , experimental group significantly less than control.
