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

Figure 4

Comparison of the mean force (N) load and unload deflection between coated and regular Borgatta 0.016′′ Ni-Ti wires. There was a statistically significant decrease in the coated Ni-Ti wires at 2 mm (), 3 mm (), and 5 mm () load deflection compared with regular Ni-Ti wires. For the unload deflection, the coated Ni-Ti wires showed a significantly decreased deflection at 1 mm () and 2 mm () compared with the regular Ni-Ti wire.
