Evaluation of the mechanical behaviour of PathFile and ProGlider pathfinding nickel–titanium rotary instruments

Abstract

ProGlider NiTi pathfinding instrument manufactured from M-Wire alloy had enhanced mechanical properties, including higher flexibility, higher resistance to cyclic fatigue and torsional stress compared with PathFile instrument made of conventional NiTi alloy.

Comparison of the Cyclic Fatigue Resistance of 5 Different Rotary Pathfinding Instruments Made of Conventional Nickel-Titanium Wire, M-wire, and Controlled Memory Wire

“…Similarly, numerous studies reported that instruments manufactured with M-wire alloy are more resistant to cyclic fatigue than those made from conventional NiTi wire (13,16,17,23,24,30). In accordance with our findings, Elnaghy and Elsaka (34) reported that ProGlider instruments revealed higher cyclic fatigue resistance compared with that of PathFile instruments.…”

Resistance to cyclic fatigue of PathFile, ScoutRaCe and ProGlider glide path files in an S‐shaped canal

“…). A comparison of the CFR of ProGlider files and PathFile files determined that ProGlider files had greater CFR than PathFile (Elnaghy & Elsaka ). This is consistent with the findings of the current study.…”

Torsional fatigue resistance of pathfinding instruments manufactured from several nickel‐titanium alloys

“…This test attempts to simulate a standardized and extreme clinical situation with high torsional load (Kim et al . , Elnaghy & Elsaka , Arias et al . ) and has been previously described (Elnaghy & Elsaka , Arias et al .…”
