Comparison of radiographic density and compaction index of root canal obturation using nickel titanium or stainless-steel spreaders

open access: yesThe Journal of Qazvin University of Medical Sciences, 2016
Background: Both nickel titanium and stainless-steel spreaders are available. The obvious advantage of nickel titanium spreader over stainless steel spreaders is greater penetration in curved canals.

Simulation of Titanium and Titanium Alloy Powder Compact Forging

open access: yes, 2011
Simulation can be divided into two types: physical simulation and interactive numerical simulation. Physical simulation depends on testing smaller or cheaper samples rather than real objects to simplify models; Interactive simulation, which is also been ...

An In Vivo Randomized Clinical Evaluation of the Surface Morphology of Nickel-Titanium, Beta-titanium, and Copper-Nickel-Titanium.

open access: yesThe journal of contemporary dental practice, 2020
Variation in the surface roughness of archwires not only leads to more accumulation of plaque but also modifies the coefficient of friction. This necessitated for the present study to evaluate the surface characteristics of 0.016 × 0.022-inch nickel-titanium, beta-titanium, and copper-nickel-titanium archwires, before and after their use in the oral ...
