Background: The clinical application of temporary anchorage devices (TADs) and specifically of orthodontic mini-implants has been increased lately. The present study was conducted to assess factors related to the clinical application of orthodontic mini-implants. Materials & Methods: The present study was conducted on 106 patients who were given mini implants of both genders. Factors related to patients such as implant length, systemic diseases, bone width and malocclusion was recorded. Results: There were 66 males and 40 females. Males had 80 and females had 52 dental implants. There was 22 mini implants failure in patients with 42 systemic diseases, maximum implant failure was seen in type IV bone (12) followed by type III (10), II (8) and I (12), 10 in 68 >12 mm height, 12 in 42 10-12 mm implant height and 10 in 22 <10 mm height. Implant failure was seen in 15 in bone width <3.75 mm, 20 in 3.75- 4 mm and 7 in >4 mm and 27 out of 62 patients with malocclusion. Conclusion: Authors found that factors such as bone height, width, malocclusion, systemic diseases and bone type determine the outcome of mini implants.
