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.
Medical applications for nitinol include:
- Dentistry, especially in orthodontics for wires and brackets that connect the teeth. “Sure Smile” dental braces are an example of its application in orthodontics.
- Endodontics, mainly during root canals for cleaning and shaping root canals.
- In colorectal surgery, the material is used in various devices for reconnecting the intestine after a pathology is removed.
- Orthopedic implants.
- Wires for marking and locating breast tumors.
- Tubing for a range of medical applications.
