Coated and Uncoated Nickel-Titanium Archwires: Mechanical Property and Surface Topography Response to a Simulated Oral Environment with and without Bracket-Related Load Deflection Induced Stress
(University of Missouri--Kansas City, 2017)This study examined the effect of exposure to bracket-related load deflection on the mechanical properties and surface characteristics of esthetic coated and uncoated nickel titanium archwires. Two types of coated ... -
The effect of archwire vibrations on the stick-slip behavior of the bracket-archwire interface utilizing clinically relevant tipping moments
(University of Missouri--Kansas City, 2011-07-27)This study evaluated bracket-archwire frictional resistance as a function of ligation method and archwire vibration. In vivo archwire vibrations were measured to obtain frequencies and amplitudes for ex vivo testing. ... -
The effect of phosphoric acid etch in conjunction with self-etching primer on enamel surfaces and resultant orthodontic bracket bond strength
(2013-11-27)This study examined the methods of preparing the enamel surface for orthodontic bracket adhesion in overcoming pellicle and possible fluid contamination from prebonding cleaning techniques and the effect of these treatments ... -
The effect of simulated oral and clinical conditions on the fracture strength of ceramic bracket tie-wings
(University of Missouri--Kansas City, 2011-08-12)This study examined the effect of simulated oral and clinical conditions on the tie-wing fracture strength of a polycrystalline and a monocrystalline bracket. Fracture strength was measured for brackets as-received ... -
The Effect of Topical Fluoride Agents on Coated Nickel-Titanium Archwires
(2015)This study examined the effect of exposure to topical fluoride agents on the mechanical properties and surface characteristics of esthetic coated nickel-titanium archwires. Two types of coated wires were tested: one with ... -
Intraoral Corrosion of Self-ligating Metallic Brackets and Archwires and the Effect on Friction
(2014)The purpose of this study was to investigate how the frictional coefficient was affected due to intraoral use. A secondary aim of this study was to determine whether or not there was a relationship between corrosion of ... -
The Effect of Simulated Oral Conditions on Surface Roughness and Friction Properties of Surface-treated and Non-surface Treated Nickel-Titanium Archwires: A Pilot Study
This study examined the effect of simulated oral conditions (storage in phosphate-buffered saline (PBS) with bracket-related load deflection at 37±1°C for 12 weeks) on surface-treated and non-surface treated NiTi archwires. ...
