Understanding the Shape-Memory Alloys Used in Orthodontics

<table>Supereleastic (red) and thermal activated (blue) NiTi 0.012-inch orthodontic archwires during three-point bending test. Note different yielding points (<i>Y</i>1, <i>Y</i>2), Martensite and Austenite start  (Ms, As) and finish (Mf, Af) phases transformation and the temperature of transformation (TTR).</table>
