Comparison of cyclic fatigue and torsional resistance in reciprocating single-file systems and continuous rotary instrumentation systems
(Nihon Univ, School Dentistry, 2014-12-01)
As compared with continuous rotary systems, reciprocating motion is believed to increase the fatigue resistance of NiTi instruments. We compared the cyclic fatigue and torsional resistance of reciprocating single-file ...
Accidental torsion in buildings: analysis versus earthquake motions
(2001)
A simplified analysis procedure has been developed to consider accidental torsion in building design that is rational and convenient relative to building codes. This procedure is extended and evaluated in this paper against ...
Torsional fatigue resistance of pathfinding instruments manufactured from several nickel-titanium alloys
(Wiley-Blackwell, 2018-06-01)
AimTo evaluate the torsional properties of pathfinding nickel-titanium (NiTi) rotary instruments manufactured from several NiTi alloys, ProGlider (M-wire), Hyflex GPF (conventional NiTi Wire and controlled memory wire), ...
Cyclic fatigue and torsional strength of three different thermally treated reciprocating nickel-titanium instruments
(Springer, 2018-05-01)
Objectives The aim of this study was to evaluate the cyclic and torsional fatigue resistance of the reciprocating single-file systems Reciproc Blue 25.08 (VDW GmbH, Munich, Germany), Prodesign R 25.06 (Easy Dental Equipment, ...
Incidencia de la irregularidad torsional y torsional extrema en las cantidades de obra de una estructura de concreto reforzado
(2020-12-10)
The present work shows the incidence in the quantities of work of a reinforced concrete structure in which will be compare variables such as the concrete and the longitudinal and transversal reinforcement of the elements ...
Some fundamental aspects of torsionally coupled structures
(2000)
Buildings with coupled lateral and torsional motions are continuously cited as classical examples of structural damage during an earthquake. There is nothing intrinsically wrong with a coupledstructure that justifies such ...
NEW COUPLING SYSTEM FOR INTERFERENCE SCREWS: BIOMECHANICAL RESISTANCE TO TORSION
(ATHA COMUNICACAO & EDITORA, 2011)
Objective: To introduce a new coupling system between screw driver and interference screw, and biomechanical tests that validate the safety of its application. Methods: The new system was submitted to biomechanical torsion ...
Influence of cyclic flexural deformation on the torsional resistance of CM files in comparison to conventional NITI instruments
(Universidade Federal de Minas GeraisUFMG, 2016-07-16)
Introduction: To evaluate the influence of cyclic deformation on the torsional resistance of NiTi controlled memory (CM) files, when compared to superelastic (SE) instruments with similar geometric and dimensional ...
In vitro study of fracture resistance of bovine roots using different intraradicular post systems
(Quintessence Publ Co IncCarol StreamEUA, 2004)
Desenvolvimento e caracterização de nanocompósitos Al/Nb2O5 processados por high-pressure torsion
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2019-07-12)
The transportation industry searches not only for lighter materials, but also for materials that are resistant, in order to reduce fuel consumption and consequently to suits in the environmental regulations. To achieve ...
