Orthodontic mini implant and their primary stability: A comparative study

Background: Mini implants has been widely used now a days as anchorage for achieving best orthodontic outcome. Good primary stability of mini is key their success. Two type implant (one single threaded and other double threaded) were this study, insertion torque removal was evaluated.Material Method: 40 patients selected two equal (n=20) groups formed. In first group (group1) used, in second (group 2) used. Maximum (m.i.t) (m.r.t) recorded groups. Statistical analysis done.Results: Torque compared both group. Max. Insertion (mit) found higher than max. Removal (mrt) the between Higher values m.i.t m.r.t intergroup comparison.Conclusion: screws are effective temporary device. Double more torque, so they have better stability.
