@dr.nicoleorthodontics: HOW DO ORTHODONTIC WIRES WORK⁉️❓ 🦷 EXPLANATION IN PREVIOUS POST! At lower temperatures (room temp) Niti is in martensite state. The “martensite” is stable and shape memory can occur while engaging rotations in teeth. At higher temperatures (in mouth) Niti alloy wires transition to the “austenite” state. This state is lower stress and the original shape is restored. This process is known as heat activation which is the ability of a material to go from a martensitic state → austenitic state when temperature is increased! #magic #dentist #orthodontist #braces #nickeltitaniumalloy
