- NiTi Closed Coil Spring is ideal for cuspid retraction and closing extraction space.

- The low force, long acting properties of the Nickel-Titanium Closed Coil makes for an ideal force application when sliding one cuspid along an archwire activated a small amount.

- Greater activation of the coils results in higher forces that can be applied to closing extraction spaces with sliding mechanics.

- A major advantage is the long "range of activation" of nickel-titanium, allowing for extended appointment intervals, typically 8 weeks between reactivation.
