Various types of mechanics have been used; one of the most successful was a power arm, used originally by Dr Larry Andrews. The power arm helps to direct the force applied on the tooth towards the center of resistance to produce translation. In this study we wanted to eliminate the moment to force ratio (M/F) created between the bracket slot and the wire, reducing the amount of tipping in the tooth Locating the center of resistance to produce bodily movement and to find a relationship between the length of tooth and hook extension is necessary. Therefore, we proposed a 3-Dimensional Finite Element Analysis method demonstrating the bodily movement of canines, using an extendable hook attached to the bracket. Materials and Methods: Eight 3D computer models of an upper right canine were designed in SolidWorks 2006, and the teeth were modeled according to Ash’s Dental Anatomy. The models were the same except for their extension arm heights. A force of l Newton was applied to the end of the hook. The models were transferred to the ANSYS Workbench Version 10 for analysis.
