WebThe efficacy of a closing loop lies in its ability to produce bodily movement by incorporating less force and more moment. The force and moment exerted by the loop depends upon the properties of the archwire material, length of the loop, and range of horizontal activation of the loop [Citation 8, Citation 14].

Webby a continuous closing loop archwire has only been studied on a limited basis. Various experimental or computational studies3–8 have been performed on the force systems.These studies4–6 have concludedthat the force system is multifactorial and can be adjusted, and a 3D analysis is needed to study the force system of an
WebA systematic approach to closing loop design for use in continuous arch wires was presented in Part I. The design process used Castigliano's theorem to derive equations for moment-to-force ratio (M/F) in terms of loop geometry. The equations were used to optimize designs by optimizing M/F to produce tooth movement via translation. memory haxWebClosing-loop archwires have traditionally been activated in several ways.
