What is Nitinol used for?
Nitinol is used for the wiring and brackets that connect teeth. It’s the perfect choice for braces because the alloy is able to bend and shape itself to the requirements of the patient’s tooth formation. In endodontics, Nitinol is used during root canals, specifically for cleaning and helping to shape the root canal.
What products are made from Nitinol?
Nitinol Heat Engine.
Is Nitinol toxic?
We conclude that Nitinol has good in vitro biocompatibility with human osteoblasts and fibroblasts. Despite the higher initial nickel dissolution, Nitinol induced no toxic effects, decrease in cell proliferation, or inhibition on the growth of cells in contact with the metal surface.
Is Nitinol memory metal?
The most common memory metal is called NiTinol, consisting of equal parts of nickel and titanium. The table below displays alloys having shape memory effects. The memory transfer temperature is the temperature that the memory metal or alloy changes back to the original shape that it was before deformation.
What is nitinol stent?
Nitinol stents are manufactured to a size slightly larger than the target vessel size and delivered constrained in a delivery system. After deployment, they position themselves against the vessel wall with a low, “chronic” outward force. They resist outside forces with a significantly higher radial resistive force.
How is Nitinol used in braces?
The wire “remembers” its former shape. Nitinol relates to your braces treatment in a couple of ways: Instead of using stainless steel, nitinol can be used for your arch wire – the wires connecting the braces brackets. As the memory wires tries to straighten out, it will exert gradual pressure on your teeth.
What makes nitinol unique?
Nitinol is a metal alloy of nickel and titanium with unique properties, including superelasticity or pseudoelasticity and “shape memory” properties. That means nitinol can remember its original shape and return to it when heated. It also shows great elasticity under stress.
Where did nitinol come from?
The term nitinol comes from its composition and where it was discovered: nickel titanium/naval ordnance laboratory. In 1959, two scientists were exploring the properties of metal alloys.
Where is Nitinol used in the body?
A particularly important use of Nitinol is in stents. Figure 1shows an illustration of stent application: normal blood flow in an artery (Figure 1(a)), decreased blood flow due to plaque (Figure 1(b)), and a stent placed to open the artery and restore blood flow (Figure 1(c)) (7).

How does Nitinol wire work?
In robotics, Nitinol can be used as an actuator where an electrical current (or heat) is applied to a stretched wire, and the wire will contract while the charge is applied and relax once the charge is removed. Unlike most metals, Nitinol contracts in length when heated but will maintain the same absolute volume.
