No Energy Loss
The difference between loading force and unloading force is known as hysteresis. The red curves illustrate the behavior of NiTi, a shape memory alloy, which lacks an elastic limit and doesn't undergo permanent deformation. Despite always returning to its original shape, NiTi exhibits hysteresis.
In contrast, GUMMETAL wire displays 'True Elasticity' within its elastic limit, setting it apart from Ni-Ti wire, which only demonstrates Pseudo-Elasticity. This distinction results in hysteresis and subsequent 'energy loss.'
In orthodontic applications, the upper red curve represents the loading force, while the lower red curve represents the unloading force. When clinicians bend wires for individual patients, they must anticipate the amount of unloading force required to move the teeth. Ni-Ti wires, characterized by hysteresis, offer imprecise unloading force predictions. However, GUMMETAL's absence of hysteresis ensures greater precision in orthodontic force and facilitates clinician work.
NO hysteresis = NO energy loss.
