Nitinol wire Application areas

1. Used in super-elastic memory alloy mobile phone antennas, children’s toy antennas, optical frames, with the development of the times, gradually used in women’s corsets, as scientific research materials, frequently appear in various science and engineering college materials laboratory.
2. One-way shape recovery using one-way shape memory effect. Such as pipe joints, antennas, collars, etc.
3. External cause two-way memory recovery. That is, the single-pass shape memory effect is used and repeated actions are performed with the external force with the temperature rise and fall, such as a heat sensitive element, a robot, a binding post, and the like.
4. Super elastic application. Such as springs, binding posts, frames, etc. The memory alloy material frame is exemplified by a spring made of a memory alloy. The spring is placed in hot water, and the length of the spring is immediately elongated, and then placed in cold water, and it immediately returns to its original state. The shape memory alloy spring can be used to control the water temperature of the bathroom water pipe. When the hot water temperature is too high, the water supply pipe can be adjusted or closed by the “memory” function to avoid burns. It can also be used as a security device for fire alarm devices and electrical equipment. When a fire occurs, the spring made of the memory alloy is deformed, and the fire alarm device is activated to achieve the purpose of the alarm. It is also possible to place a spring made of a memory alloy in a heated valve to maintain the temperature of the greenhouse, and to automatically open or close the heater valve when the temperature is too low or too high.
5. The biocompatibility of TiNi alloy is very good, and there are many medical examples using shape memory effect and superelasticity. Such as thrombus filter, spinal orthopedic rod, orthodontic wire, cerebral aneurysm clip, bone plate, intramedullary nail, artificial joint, contraceptive, cardiac repair component, micro pump for artificial kidney, etc.

Clinical application of nickel-titanium alloy wire

1. Early alignment and flattening of the patient’s dentition Due to the superelasticity and shape memory properties of the Nitinol archwire and the low stress-strain curve, the Nitinol archwire is routinely included as the initial phase in the correction system. The archwire, in this way, the patient’s discomfort will be greatly reduced. Due to the existence of several different straight wire bowing techniques, MBT technology recommends the use of 0.016 inch heat activated Nitinol arch wire (HANT wire). The DEMON self-locking bracket technology recommends the use of copper-containing heat activated nickel-titanium produced by Omcro. Alloy arch wire (phase transition temperature is about 40 degrees), O-PAK correction technology is recommended to use 0.016 inch superelastic nickel-titanium alloy arch wire for early alignment.
2. Nickel-titanium spring: Nickel-titanium push spring and tension spring are springs used for orthodontics of teeth. They are special for nickel-titanium superelasticity. They are suitable for orthodontic treatment to develop gaps between teeth and pull teeth in different directions. A nickel-titanium coil spring elongated by 1 mm produces a force of approximately 50 g. Nickel-titanium coil springs have high elastic properties and produce a softer and stable durability under tension. The attenuation of the force is small and produces the ideal orthodontic force required to meet the clinically moving teeth. Meet physiological requirements. The nickel-titanium wire tension spring has a high degree of elasticity and a very low permanent deformation rate, and the release force of the same is different from that of the same diameter of the stainless steel wire by a factor of 3. 5 – 4 times. Therefore, in orthodontic treatment, the patient not only has mild pain, but also feels soft and lasting, and the time for re-diagnosis is reduced, the course of treatment is shortened, and the curative effect is improved. It is a new excellent mechanical device in orthodontic treatment.
3. L-H arch wire is developed by Dr. Soma of Japan and produced by Tomy. “LH” is named “Low Hysteresis”, that is to say, when the archwire is ligated to the bracket, that is, the stress generated when the archwire is activated and the tooth is slowly recovered when the tooth is moved. The difference in stress generated in the original state is small. The lag is small. SOMA et al. compared the stress-strain curves of LH archwires and other Ni-Ti alloy wires. The LH archwire has the smallest hysteresis range. This feature gives archwires the advantage of low load and sustained light force, while the initial slope of the curve is low. It shows that the rigidity of the archwire is low, and the hysteresis curve of the other types of Nitinol archwires indicates that the rigidity is large. It is obvious that the LH archwire has obvious mechanical advantages. Since the content ratio of titanium in the LH wire nickel-titanium component is higher than that of the general nickel-titanium arch wire, it is called titanium-nickel wire, and experiments have proved that the shock absorption effect is strong. Another feature of LH nickel-titanium wire is that it can be bent and heat-set by heat treatment equipment, so LH nickel-titanium wire can also be leveled, opened and closed, and closed, and the final stage of completion.

Phase transition and properties of Nitinol

As the name suggests, Nitinol is a binary alloy composed of nickel ions and titanium ions. Due to changes in temperature and mechanical pressure, there are two different crystal phases, namely the austenite phase and the martensite phase (Martensite). The phase transition sequence of the nickel-titanium alloy during cooling is the parent phase (austenite phase)-R phase-martensite phase. The R phase is a rhombohedral shape, and the austenite is a state in which the temperature is higher (greater than the same: the temperature at which the austenite starts to be heated), or the state at which the load is removed (external force removal Deactivation), the cube is hard. The shape is relatively stable. The martensite phase is a state in which the temperature is relatively low (less than Mf: the temperature at which martensite ends) or loading (activated by external force), hexagonal, malleable, repeatable, less stable, easier Deformation. Therefore, it is clinically determined that the phase transition temperature of Nitinol archwire has a positive guiding significance, so that clinicians can better utilize the performance of Nitinol for clinical orthodontic treatment.

It is a new excellent mechanical device in orthodontic treatment.

Another feature of LH nickel-titanium wire is that it can be bent and can be heated and shaped by heat treatment equipment. Therefore, LH nickel-titanium wire can also be leveled, opened and closed to the closing gap, and the final stage of completion. That is to say, the treatment can be completed, as long as the arch wire is taken out and bent in a desired shape at each stage, and then shaped by a heat treatment instrument to strengthen the hardness. At present, L-H archwire is used in the clinical expansion of the bow to correct the open jaw, partial jaw and anti-jaw, because its strength is sustained and soft, and the effect is better. At the same time, J hooks are often used together to improve the softness of the archwire. Although MEAW technology has an ideal effect for correcting the above-mentioned malocclusion, complicated arch bending often makes many physicians discouraged. Therefore, some physicians have changed the rocker-type nickel-titanium arch wire similar to the mechanical system and the vertical traction of the anterior teeth. Although this has similar effects, it is always felt that compared with the MEAW, the individual tooth movements are not as good as the MEAW technology. The rocker-type nickel-titanium wire is a continuous archwire and there is no way to bend it. Therefore, the angle of the bracket bonding and the rocking curvature of the archwire determine the angle of each tooth, unlike the angle of each tooth in the MEAW technology. Use LH nickel-titanium to bend the rocking chair, and then use the arch wire shaper to bend in the mouth and then bend or bend forward. The effect is quite satisfactory.
