Survival Analysis of Orthodontic Micro-Implants: A Retrospective Study on the Effects of Patient-Related Factors on Micro-Implant Success

The purpose of this study was to investigate the effects patient-related factors such as anteroposterior and vertical skeletal patterns alveolar bone density on success rate micro-implants. Cases orthodontic micro-implants (n = 404; diameter, 1.6 mm; length, 6 mm) were investigated in 164 patients (127 women, 37 men; mean age, 23.6 ± 5.8 years). Cortical thickness measured using diagnostic cone-beam computed tomography examine their micro-implant’s survival. Moreover, facial considered independent variables for Marginal survival analysis performed by analyzing time from implant placement removal failed micro-implants, or end treatment successful Variables including sex, implantation side, site, root proximity, type loading (immediate vs. delayed) also assessed. In total, 347 (85.9%) 404 successful. 12.4 4.3 months. showed that risk failure not statistically significant. significantly associated with micro-implant cortical density, replanted same site. conclusion, our findings indicate are may be success.
