Properties
§
Safe
for nickel sensitive patients
§
Low
modulus of elasticity (1/2 of stainless steel)
§
High
springback and flexibility
§
Low
force-deflection rate
§
Moderate
stiffness (approximately 42% of steel)
§
May
be deflected 100% more than stainless steel without permanent deformation
§
Good
corrosion resistance and excellent weldability
§
Formability
similar to stainless steel
§
A
smoother surface for low friction
§
Carefully
processed to reduce breakage during formation or activation
Clinical Applications
§
Added
arch form length makes it ideal for closing loops and/or intricate bends
§
Less
force than stainless steel
§
Allows
for larger activations
§
Smaller
increments of force loss during deactivation
§
Formability
allows for intricate loop designs
§
Springback
is not lost by bending
§
Weldability
allows for placement of stops or auxiliary loops
|
Sliding Space Closure
§
Friction
characteristics comparable to stainless steel for faster sliding mechanics
§
Bendability
allows for placement of tie-back loops
§
Weldability
allows for placement of stops
§
Adequate
stiffness for root correction
Alignment or Finishing Wire
§
Withstands
twice as much deflection as stainless steel before permanent deformation.
§
A
great finishing wire.
§
Formability
allows for bypasses
§
Overcorrection
is possible by placing bends
§
Gentler
force delivery with larger archwire sizes
§
Ability
to place finishing bends
Other Uses
§
Utility
arches
§
Torquing

§
Palatal
bars
§
Lingual
arches
§
Multi-looped
arches
