Abstract: The purpose of this study is to propose a new appliance called stabilizing leg, which is designed as an additional anchorage providing device to improve the primary stability of orthodontic small screws. For this purpose, two finite element models (FEM) with different cortical layer thickness of 1   mm and 2   mm were taken into account. In order to achieve stability analysis, the two main models, model I and model II, are divided into subgroups according to the length of stability outrigger. Two types of forces are considered. (1) The first force is a constant force   n of 1, which is applicable to all two models. (2) The second force is defined in the range of 1 – 4
