In Part I, a systematic approach to closing loop design for use in continuous arch wires is presented. The design process uses Castigliano's theorem to derive equations for moment-to-force ratio (M/F) in terms of loop geometry. The equations are used to optimize designs by optimizing M/F to produce tooth movement via translation.
