Niti properties: 1.Exerts light continuous forces when deflected to relatively large distances, with minimum permanent deformation. 2.Decreases number of arch wire changes. 3.Requires less chair time. 4.Shortens treatment time required to accomplish rotations and leveling. 5.Produces less patient discomfort. Nickel-Titanium alloys contain approximately 54% Ni, 44% Ti and generally 2% or less of Co. This composition results in one-to-one atomic ratio of the major components. As with other systems, this alloy can exist in various crystallographic forms. At high temperatures, a body centered cubi...
