    Aims: to compare the load-deflection ratios between three groups of super elastics nickel-titanium orthodontic wires from three different manufacturers super elastic 0.012-inch wires. Materials and Methods: the sample examined were 150 nickel-titanium alloy orthodontic wires commercially available from three different manufacturers (IOS, A-star and DENXY super elastics nickel-titanium 0.012 inch wires ) were tested for load deflections rate, the records were taken with the aid of digital Universal testing machine(compression tension machine), simulating an extrusive force at the right canine (TYPODONT model) , in-activations of 0 to 3 mm, with readings of the force released by deflection in unloading of 0.5mm, starting from 2.5mm, 2mm,1.5mm,1mm, 0.5mm consequently. Results: statistically significant diff.. Read More»
