Abstract
This research studied the effects of T-loop's size to the traction force and the load/deflection which will be considered in orthodontic loop design. The dimensions of T-loops are varied and the relations between deflection of loop legs and horizontal forces are analyzed using the finite element method. The results show that the distance between loop legs does not affect to the horizontal force and load/deflection. More horizontal length of T-loop will decrease the horizontal force. Furthermore, the total loop height significantly affect to the horizontal force. A loop with more height leads to smaller horizontal force. The result of this research can then be used in an optimum T-loop design and also be acted as a guideline for an analysis of other closing loops
