Objective: To use a systematic review to determine which all are the contributing factors that play role in success rate of orthodontic mini-implants.
Materials and methods: Different databases were searched without limitations up to July 2015. Additionally, the bibliographies of the finally selected articles were hand searched to identify any relevant publications that were not identified earlier. In vitro and in vivo articles were included. Both human and animal studies were included. Thirty five articles were initially selected, finally 28 articles were included in the study.
Conclusion: This review article conclude that success of orthodontic mini-implants depends on multiple factors which can be broadly classified under four headings- mechanical factors, biologic factors, placement technique, microbial factors. Mechanical factors included diameter of mini-implants, surface characteristics, load and its relation with implants, microgrooves, miniscrew versus manipulates, biologic factors included Inter-radicular space, skeletal growth pattern, placement site, racial factors, root proximity, placement techniques such as self-tapping and self-drilling placement, laser therapy, reinstalled mini-implants, pre drilling diameter play a vital role in success of implants. Microbial factors such as microbial floral changes after implant placement and inflammation surrounding the implants also have an important role in success and failure of implant.
