Nitinol
This is a type of shape memory metal and it’s used in 3D printers. Shape memory alloy is an alloy that has a good plasticity and can restore its deformation automatically at a given temperature.
Nitinol alloy is made up of two metals, titanium and nickel. The austenite phase, and the martensite, are different phases of crystallization due to temperature and mechanical stress changes. The nickel-titanium metal alloy has a unique shape memory feature, but also excellent characteristics like wear resistance and corrosion resistance. It is also super elastic, damping high vibrations, and highly durable.
The material automatically returns to its mother phase when it undergoes a reverse phase transformation. It is true that the shape memory process is a thermally initiated phase transformation of Nitinol.
2.Superelasticity
Superelasticity is the phenomenon in which a sample under the influence of an external force produces a larger strain than its elastic limit, but the strain can automatically be restored upon unloading. The stress-induced martensitic transition occurs in the parent state due to stress.
3. Sensitivity in the mouth to temperature changes
The temperature in the mouth cavity does not affect the correction force of CoCr alloy wire or stainless steel wire. The temperature in the oral cavity affects the corrective force of super-elastic nickel titanium alloy orthopedic wire.
4. Corrosion resistance
According to recent studies, the corrosion resistance between stainless steel and nickel-titanium is almost identical.
5. Anti-toxicity
This alloy is a nickel-titanium atomic alloy, with about 50% of nickel. Nickel has been known to be carcinogenic, and can promote cancer. In normal conditions, the titanium oxide surface layer acts as barrier. This makes Ni-Ti alloy biocompatible. TiXOy, TixNiOy, and TixNiOy are surface layers that can inhibit Ni release.
6. Corrective correction
Currently commercially used orthopedic wires include austenitic stainless steel wires, cobalt-chromium-nickel alloy wires, nickel-chromium alloy wires, Australian alloy wires, gold alloy wires and ss titanium alloy wires. Nitinol has the lowest unloading curve and flattest platform, meaning it is capable of providing the softest correction force and durable.
7. Good shock absorption properties
The root and periodontal tissue is more damaged by the higher the vibration caused by the archwire. According to the results of various arch wire attenuation studies, the vibratory amplitude for stainless steel wire was larger than that for super-elastic nickel-Ti. The initial vibratory amplitude of Ni-Ti super-elastic arch wire is only half that of the stainless steel wire. The health of teeth is extremely important.
