DALLA ROSA, Fernando et al. Evaluation of fracture torque resistance of orthodontic mini-implants. Acta odontol. latinoam. [online]. 2016, vol.29, n.3, pp.248-254. ISSN 1852-4834.

This study sought to assess the fracture torque resistance of miniimplants used for orthodontic anchorage. Five commercially available brands of miniimplants were used (SIN®, CONEXÃO®, NEODENT®, MORELLI®, and FORESTADENT®). Ten miniimplants of each diameter of each brand were tested, for a total 100 specimens. The miniimplants were subject to a static torsion test as described in ASTM standard F543. Analysis of variance (ANOVA) with the Tukey multiple comparisons procedure was used to assess results. Overall, mean fracture strength ranged from 15.7 to 70.4 N·cm. Miniimplants with larger diameter exhibited higher peak torque values at fracture and higher yield strength, regardless of brand. In addition, significant differences across brands were observed when implants were stratified by diameter. In conclusion, larger miniimplant diameter is associated with increased fracture torque resistance. Additional information on peak torque values at fracture of different commercial brands of miniimplants may increase the success rate of this orthodontic anchorage modality.
