Applications of titanium-nickel alloy wire
1. Nickel titanium spring
Nickel-titanium push springs and tension springs are springs used in orthodontics. They have the special properties of nickel-titanium superelasticity and are suitable for orthodontic treatment to open up gaps between teeth and pull teeth in different directions. A nickel-titanium coil spring can produce approximately 50g of force when stretched 1mm.Nickel-titanium coil springs have high elastic properties and can produce softer and more stable sustained force in the stretched state. The force attenuation is very small, and it can produce ideal orthodontic force that meets the clinical needs of moving teeth. Meet physiological requirements. Nickel-Titanium Wire tension springs have high elasticity and extremely low permanent deformation rate. Compared with stainless steel wires of the same diameter, the correction force released is 3.5-4 times different.Therefore, in the application of orthodontic treatment, patients not only have less pain, but also feel soft and lasting strength, and the time for follow-up visits is reduced, the course of treatment is shortened, and the efficacy is improved. It is a new and excellent mechanical device in orthodontic treatment.
2. Arch wire of dental correction system
Used for early alignment and leveling of patients' dentition. Due to the superelasticity and shape memory properties of nickel-Titanium Alloy archwires and their low stress-strain curves, nickel-titanium alloy archwires are currently routinely used in clinical practice as the initial archwires incorporated into the correction system. In this way, the patient's discomfort will be greatly reduced.Since there are currently several different straight wire arch correction technologies, MBT technology recommends the use of 0.016-inch heat-activated nickel-titanium alloy arch wire (HANT wire), DEMON self-ligating bracket technology recommends the use of copper-containing heat-activated nickel-titanium alloy arch wire produced by Omcro (the phase change temperature is about 40 degrees), and O-PAK correction technology recommends the use of 0.016-inch super-elastic nickel-titanium alloy arch wire for early alignment and leveling.
