## Key Features

HyFlex EDM

EDM + CM-Wire with regenerative memory — manufacturer reports enhanced fatigue resistance (bench data; figures vary by comparator and test setup)

TruNatomy

Slim 0.8mm MFD with off-centered parallelogram cross-section preserves peri-cervical dentin while maintaining shaping efficiency
