1. Early alignment of patients' dentition due to the hyper elasticity, shape memory performance and low stress-strain curve of Nitinol alloy arch wire, currently Nitinol alloy arch wire is routinely used as the arch wire in the initial orthodontic system, so that patients' discomfort will be greatly reduced. Because there are several different straight wire bow rectification technology, MBT technology is recommended to use 0.016 inches thermal activated nickel titanium arch wire (HANT silk), DEMON self-locking braces technologies recommended by Omcro company production of thermal activated nickel titanium alloy containing copper arch wire (phase change temperature about 40 degrees or so), O - PAK rectification technology is recommended to use 0.016 inches hyper elastic nickel titanium alloy used in early row of neat the arch wire.

2, nickel-titanium spring: nickel-titanium push spring and tension spring is a kind of spring used for orthodontic teeth, with nickel-titanium super elastic special, suitable for orthodontic treatment to open up the space between the teeth and pull teeth in different directions. The nickel-titanium coil spring extends by 1mm and produces a force of about 50g.Nickel-titanium helical spring has very high elastic properties, which can produce relatively gentle and stable continuous force in the state of tension. The force attenuation is very small, which can produce ideal orthodontic force for clinical tooth movement. Meet the physiological requirements. Nickel-titanium wire tension spring has high elasticity and low permanent deformation rate. Compared with stainless steel wire of the same diameter, the correction force released by it differs by 3.5-4 times. Therefore, in the application of orthodontic treatment, patients not only have light pain, but also have mild and lasting sensory strength, and the time of return visit is reduced, the course of treatment is shortened, and the curative effect is improved, which is a new and excellent mechanical device in orthodontic treatment.
