Stability and success rate of dual-thread miniscrews:

ABSTRACT Objectives To date, the clinical stability of dual-thread orthodontic miniscrews has not been studied. This study aimed to compare primary and long-term success rate cylindrical examine association between various factors miniscrews. Materials Methods A total 145 135 were inserted in maxillary mandibular buccal alveolar areas 142 patients. The torque Periotest (Siemens, Bensheim, Germany) values recorded during insertion removal. effect variables such as sex, age, screw design, jaw, side placement, root proximity, site placement on was examined using logistic regression analysis. Results There no statistically significant difference (P = .595) overall two designs, with an 82.1% 84.4% for miniscrews, respectively. Age screw-root proximity significantly associated failure < .05). Conclusions did show superior compared results this suggest that patient age influence
