Fatigue testing of a NiTi rotary instrument. Part 2: fractographic analysis

International Endodontic Journal, 2007
Abstract Aim  To examine the topographic features of the fracture surface of a NiTi instrument after fatigue failure, and to correlate the measurements of some features with the cyclic load. Methodology  A total of ...

Instrumented micro-indentation of NiTi shape-memory alloys

Acta Materialia, 2001
Abstract We study the instrumented Vickers micro-indentation of single-crystal Ti–50.9 at% Ni shape-memory alloys with systematically varied surface normal orientations ([100], [210], [111] and [221]) and Ti3Ni4 precipitate sizes (0 nm, 10 nm, 50 nm, 100 nm, 300 nm and 500 nm).

Evaluating the cutting efficiency of NiTi instruments with reciprocating motions

Arquivos em Odontologia, 2018
Aim: This study tested a setup for in vitro experimental analysis of axial forces and torque during the preparation of artificial canals using nickel-titanium reciprocating endodontic files. Methods: The cutting efficiency of Reciproc (RC) and WaveOne (WO) reciprocating size 25/.08 instruments (n = 10) was evaluated, taking into account their ...

[In vitro investigation of three NiTi rotary instruments].

Fogorvosi szemle, 2014
The purpose of our study was to compare the shaping ability of three nickel-titanium rotary instruments (RaCe/FKG Dentaire/, ProTaper /Dentsply-Maillefer/ and M(two)/VDW/) by measuring the asymmetry that occurs in curved canals during instrumentation.
