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.38.e1-38.e6openAccessoral cavitydentistryimplantsbrasschannelingArtigo de periódico41510.1590/S2176-94512010000400006https://orcid.org/0000-0002-8304-9939
