Galvanic corrosion between orthodontic wires and brackets in fluoride mouthwashes.
The aim of this investigation was to determine the influence of fluoride in certain mouthwashes on the risk of corrosion through galvanic coupling of orthodontic wires and brackets. Two titanium alloy wires, nickel-titanium (NiTi) and copper-nickel-titanium (CuNiTi), and the three most commonly used brackets, titanium (Ti), iron-chromium-nickel (FeCrNi) and cobalt-chromium (CoCr), were tested i...
متن کاملGalvanic Corrosion of Orthodontic Brackets and Wires in Acidic Artificial Saliva: Part II
Objective: Orthodontic wires should have high resistance against corrosion in the oral environment. Since the effect of pH on corrosion has been well recognized, this study sought to assess and compare the electrochemical corrosion of orthodontic brackets and wires of different brands in acidic artificial saliva. Methods: This in vitro experimental study was conducted on 24 mandibular centr...
متن کاملCorrosion of Orthodontic Wires According to Heat Treatment Conditions
Heat treatments are applied to orthodontic wires in order to relieve the stresses arising during orthodontic work. Four types of wires were heated in air, argon or vacuum environments, and cooled in the furnace or in a water bath. The susceptibility to corrosion and mechanical properties of the heat-treated wires were investigated. Heat treatment marginally increased the yield strength and elas...
متن کاملIn vitro physical, chemical, and biological evaluation of commercially available metal orthodontic brackets
OBJECTIVE This in vitro study was undertaken to evaluate the physical, chemical, and biological properties of commercially available metal orthodontic brackets in South Korea, because national standards for these products are lacking. METHODS FOUR BRACKET BRANDS WERE TESTED FOR DIMENSIONAL ACCURACY, (MANUFACTURING ERRORS IN ANGULATION AND TORQUE), CYTOTOXICITY, COMPOSITION, ELUTION, AND CORRO...
متن کاملcomparison of commercially available arch wires with normal dental arch in a group of iranian population
statement of the problem: the stability of orthodontic treatment depends on preserving the patient’s pretreatment arch form and arch size during and after treatment. purpose: this investigation was aimed to study the size and shape of iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...
