Resumen
Aim: The purpose of this study was to evaluate the limit of flexural strength of a miniimplant
prototype designed for Herbst appliance anchorage. Methods: After sample size
calculation, four specimens with the new mini-implant were submitted to a single cantilever
flexure test using a universal testing machine. The limit of flexural force strength was
calculated. Results: The mini-implant prototype showed a limit of flexural force strength
of 98.2 kgf (982 N), that was the lowest value found. Conclusion: The mini-implant prototype
designed for Herbst appliance anchorage can withstand flexural forces higher than
the maximum human bite forces reported in the literature.
