Description
Orthodontic anchorages have recently been reinforced by newly developed mini-implants. The aim of the present study was to investigate the mechanical strengths of infrazygomatic mini-implants. We measured the insertion torque and pull-out strength of three brands of infrazygomatic mini-implants (AbsoAnchors, Bioray, and Lomas). All three mini-implants were 2 mm in diameter, and fi ve of each brand were manually driven 6 mm into artifi cial bone. Signifi cant differences among the brands were investigated with Kruskal-Wallis tests. We found no signifi cant relationship between insertion torque and pull-out strength in any individual brand. Among the three brands of infrazygomatic mini-implants, we found no signifi cant difference in mechanical strength. The design of an infrazygomatic mini-implant may be the most important factor determining its mechanical strength.
