Background: Mini-implants are widely used as skeletal anchorage in orthodontics. To reduce implant loss rate, sufficient primary stability is required. Hence; we assessed the effect of the length of orthodontic mini-screw implants on their long-term stability. Materials & methods:A total of 10 patients scheduled to undergo orthodontic mini-screw dental implants were included in the present study. All the individual subjects received both 6- and 8-mm-long intraoral skeletal anchorage devices (TISAD/TAD), in randomly selected quadrants. Skilled and experienced orthodontists carried out all the orthodontic procedures. Using NiTi springs, loading of the TISAD/TAD were commenced with forces parallel to the occlusal plane by using NiTi springs. For a time period of 1 year, all the patients were observed.  Results: Success rate of TISAD in the 8mm group subjects was 70 percent, while success rate of 6 mm group subjects was 60 percent. Conclusion: Stability of 8 mm orthodontic mini-screws is higher than that of 6 mm mini-screws.
