Mechanical Properties of Mini-Implants Used in Extra-Radicular Anchorage

Objective: To evaluate the mechanical properties of mini-implants (MIs) manufactured from stainless steel and compare them with conventional titanium-aluminum-vanadium alloy MIs. Material Methods: The following groups were formed: G1 (n=24), 8×1.5 mm MIs; G2 12×2.0 G3 10×1.5 titanium 72 MIs inserted in infra zygomatic crest region maxilla retromolar trigone jaw 10 pigs. Pull-out, insertion torque, fracture percussion tests performed order to measure tensile strength, primary stability strength A digital torque gauge was used a universal testing machine for pull-out periotest device micromovement For morphological MI component evaluation, scanning electron microscopy (SEM) performed. D'Agostino & Pearson, Kruskal-Wallis, Dunn post-hoc normality used. Results: torques significantly higher than (p<0.05). presented similar values among groups. SEM revealed that point predominantly on fourth thread (G1 G2) seventh (G3). Conclusion: are superior those
