MaxWire

MaxWire is FKG Dentaire's proprietary shape-memory alloy used in the XP-endo family. The unique B-phase (beta titanium) transformation behavior gives MaxWire a superelastic martensitic state at room temperature (15–20°C) and an austenitic state at body temperature (37°C). In practice, the XP-endo Shaper has an ISO 30/01 shape at room temperature and expands to a large working shape in the canal at body temperature, contacting canal walls without transported forces. This adaptive expansion into canal irregularities—fins, lateral canals, oval cross-sections—provides three-dimensional shaping that conventional fixed-taper files cannot achieve.
