In Part I, the Castigliano's theorem is applied to derive the equations for the ratios of M/F and loop stiffness for four types of closing loop, namely, the vertical helical loop, T-loop, Opus9O loop, and helical T-loop. The last type of loop is a new design offered in this study. The theoretical M/F is maximized to yield the optimum closing loop configurations for canine retraction where their heights and widths are limited to 10x10 millimeters. For closing loop applications, certain serious… CONTINUE READING
