What is Nitinol Memory alloy?

Nitinolis a shape memory metal, which is an alloy that automatically returns to its original shape when heated. Its expansion is greater than 20%, its fatigue resistance is 1*10-7th power, it has damping characteristics 10 times more effective than springs, while its corrosion resistance is superior to that of the best medical grade stainless steel. Memory alloy has many other outstanding characteristics, including wear resistance and corrosion resistance. It also offers super elasticity.

Nitinol Memory alloy in Clinical Applications

Nickel-titanium extension and push springs: These springs are used for orthodontics. Super-elastic, they are ideal for orthodontic treatments to widen the gap in between teeth or pull teeth into different directions. The nickel-titanium spiral spring can generate about 50g of force when it is extended by 1mm. Nickel-titanium coil springs possess high elastic properties, and they can produce a soft and stable force under tension. The force is attenuated very little, and this can be used to produce the ideal orthodontic forces required for clinically shifting teeth. Meet physiological requirements. Nitinol wire is a high-elasticity spring with a very low rate of permanent distortion. The corrected force released by stainless steel wires of the same size is 3,5-4 times higher. When orthodontic treatment is applied, the patient does not only feel light pain, but it also lasts a long time. Also, the treatment course is shortened and the therapeutic effect improved. It is a mechanical device that has been developed for the treatment of orthodontics.

It is used to align and level the dentition of patients as early as possible. Nitinol is the archwire of choice for the first arch in an orthodontic system due to its shape-memory properties and superelasticity. Silk can reduce patient discomfort. MBT’s straight wire arch correction technology uses 0.016″ heat activated alloy nickel titanium arch wire. The DEMON self-locking brace technology uses heat activated copper-containing nickel titanium from Omcro. O-PAK correction uses 0.016″ super-elastic Nitinol Arch Wire (phase transition is around 40 degrees) for early alignment.
