Editing Nickel-Titanium (NiTi) Alloys (section)

== Applications in Dentistry ==

=== Orthodontic Archwires ===
NiTi archwires are used in the initial stages of treatment to:
* Align crowded teeth with minimal patient discomfort.
* Provide constant force that reduces the risk of [[Root Resorption]].
* '''Copper-NiTi (Cu-NiTi):''' A variant that adds copper to the alloy to make the transformation temperature more precise (often triggered by the heat of the patient's mouth).

=== Endodontic Rotary Files ===
The introduction of NiTi transformed [[Endodontics]] by allowing for:
* '''Increased Flexibility:''' Files can follow the natural curvature of the root canal.
* '''Reduced Procedure Time:''' Transition from manual hand-filing to mechanized rotary systems.
* '''Cyclic Fatigue Resistance:''' Modern heat-treated (Gold or Blue) NiTi files are highly resistant to breaking inside the canal.
