Background: This study is aimed to determine the clinical success rate of orthodontic mini screw implants by investigating the initial( from insertion till force application) & long term stability & to evaluate the various factors associated with the Stability of mini screw implants. Material and methods: The data consisted of 50 mini screw implants in 21 patients with age ranging from 14 to 26 years was selected for the study - all these patients who underwent fixed orthodontic treatment with mini-screws placed as orthodontic anchorage. Micro implants of 1.5 X 9 mm Titanium mini-screws(S.K.
