Clinical application of Ni-Ti Alloy wire

wallpapers News 2021-12-20
Due to the superelasticity and shape memory properties of Ni-Ti Alloy archwires and the lower stress-strain curve, Ni-Ti Alloy archwires are routinely used clinically as the archwires initially included in the orthodontic system. In this way, the patient's discomfort will be greatly reduced. Since there are several different straight wire arch correction techniques, the MBT technique recommends using 0.016-inch heat-activatedNi-Ti Alloy arch-wire (HANT wire), and the DEMON self-locking bracket technology recommends using copper-containing heat-activated nickel-titanium produced by Omcro. Alloy arch-wire, O-PAK correction technology recommends using 0.016-inch super-elastic Ni-Ti Alloy arch-wire for early alignment and leveling.
Ni-Ti Alloy push springs and tension springs are springs used for orthodontics and have the special characteristics of Ni-Ti Alloy superelasticity. It is suitable for orthodontic treatment to open up the gap between teeth and pull teeth in different directions. The nickel-titanium coil spring can generate a force of about 50g when extended by 1mm. The nickel-titanium coil spring has high elastic properties and can produce a softer and stable continuous force in the stretched state. The attenuation of the force is very small, and it can produce the ideal orthodontic force that meets the clinical needs of moving the tooth. Ni-Ti Alloy wire tension spring has high elasticity and a very low permanent deformation rate. Compared with stainless steel wire of the same diameter, its released corrective force is 3.5-4 times different. Therefore, in the application of orthodontic treatment, the patient not only has light pain, but also feels soft and lasting, and the follow-up time is reduced, shortening the course of treatment, and improving the curative effect. It is a new excellent mechanical device in orthodontic treatment.
