Three-point deflection testing to measure force values:- State of the art Bose ELF 3200 mechanical test system was used for 3 points bending testing of orthodontic wires controlled at 37% Celsius.
Our new HANT 300-350 wire is soft, even at room temperature but fully austenitic at 350 C in the mouth.
The HANT 30o-35o Ni TI wire is partly martensitic at room temperature.
The martensitic characteristics that we refer to are the “soft” state of the Ni-Ti material.
The material gives you the “best of both worlds” offering you a soft manipulate wire at room temperature and fully resilient wire after insertion into the mouth.
HANT 300-350 wire is martensitic below 300C.
So its soft at room temperature.
It is fully austenitic at 350C, so it is superelastic in the mouth.
Ni-Ti wires need to demonstrate extreme elasticity, consistent force and shape memory, over limited range of deflection.
Flat curve of tooth moving force evidence “Constant Force”.
Extreme elasticity shape memory is shown by near complete rebound.
Wire is tested on Bose ELF 3200 machine for every production batch.
