Its revolutionary Smileloc device utilizes the shape memory properties of 'nitinol', a nickel-titanium alloy, to attach crowns or dentures to implant abutments without cement or retaining screws.
The memory metal nickel-titanium alloy was first developed by the US Naval Ordnance Laboratory in the 1960s and commercialised under the name Nitinol, but BAE Systems believes this is the first time it has been used to build an entire suspension system.
Nitinol is a nickel-titanium alloy that provides dynamic continuous active compression, which helps to promote healing after bone fixation.

The mechanical behavior of nickel-titanium alloy is more close to that of bone tissue in comparison with other metallic implants, and it has greater effects on the bone growth and treatment of the damaged tissue.
They then looked for ways to create artificial muscle, ultimately settling on a nickel-titanium alloy.
It is made from nitinol, a nickel-titanium alloy with so-called "superelastic" shape-memory properties so that it does not lose its shape if the ear is knocked.
The devices for percutaneous closure of interatrial communications are typically made of nitinol, a nickel-titanium alloy.
A thin nickel-titanium alloy film, for example, might cycle about 100 times a second.
found that a nickel-titanium alloy, called nitinol, held a special property--it remembered and returned to its original shape after being formed into a second shape and then heated.
Baughman and his colleagues have recently created an artificial muscle with the help of nickel-titanium alloy coated in platinum particles only nanometres or billionths of a meter wide.
