How does Nitinol Memory Alloy work?

Nitinol can be used to automatically return a specific alloy’s plastic deformation back to the original shape. The alloy’s expansion rate exceeds 20%. Its fatigue life can reach 1*10 to 7. Its damping characteristics and corrosion resistance are superior to medical stainless steel. This makes it a versatile material that is well-suited for many applications. Its unique shape-memory function makes it a great choice for medical applications. Memory alloy is also very resistant to corrosion, wear, and has high damping.

Clinical use of Nitinol Memory Alloy

Spring made from nickel-titanium: These springs are for orthodontics. They can open the gaps between teeth, pull teeth in various directions and are very elastic. A nickel-titanium coil spring is capable of producing a force up to 50g when it’s extended by just 1mm. Because of their elastic properties, nickel-titanium coilsprings can generate a force of about 50g when extended by 1mm. It is possible to produce the optimal orthodontic force for moving clinically treated teeth by reducing the attenuation. Conform to the requirements. High elasticity, low deformation rates and very low constant deformation rate make Nitinol wire a tension spring. The corrective force released is 2.5-4 times greater than stainless steel wire. In orthodontic treatment the patient has mild pain and a lasting feeling. The follow-up is shorter, which improves treatment’s curative effectiveness. The new device is excellent in orthodontic treatment.

It’s used in the alignment and leveling the patients’ dentition. Because of its shape memory and superelasticity, the Nitinol Archwire is often used clinically as an initial arch for orthodontic treatment. The patient will feel much less discomfort when they use silk. MBT technology, which uses 0.016 inches of heat activated titanium alloy archwire (HANT) wire to correct straight-wire arch problems, recommends Omcro copper-containing heat activated titanium titanium. O-PAK’s correction technology recommends that alloy arch wire be used (phase transition temperature at about 40 degrees). Super-elastic Nitinol Arch wire should also be used for alignment and leveling.
