title: Specialized spring design in segmented edgewise orthodontics: further verification of dedicated software.
abstract: A software program for use in the investigation of specialized springs used in the segmented arch technique has previously been developed and an example of its clinical application has been shown. The purpose of this study was to further assess the reliability of the software in 4 tests using T-loop springs. A numerical simulation of a determined experimental condition relative to a T-loop spring was carried out in each test. Numerical and experimental results were compared, and the precision of the analytical tool was assessed relative to a variety of parameters of the spring. Since the comparison between numerical and experimental results showed good agreement along the entire range of activation of the spring, the reliability of the software is sufficient for the clinical purposes of the segmented arch technique.
