Table 1 Type of alloy and composition of Ni-Ti instruments
Ni-Ti system | Type of alloys | Composition |
|---|---|---|
Hyflex CM | CM wire | Martensite with various amounts of austenite and R-phase |
Hyflex EDM | CM wire using electrical discharge machining | No austenite phase |
Protaper Next | M-Wire | Mainly austeNi-Tic phase with little amounts of R-phase and martensite |
Wave One Gold | M-Wire using gold thermo-mechanical heat treatment | Mainly stable martensite or R-phase |
TrueNatumy | Proprietary novel heat treatment technique | R-phase and martensitic transformation |
