Mechanical Properties of Copper-Nickel-Titanium Archwires
MECHANICAL PROPERTIES OF COPPER-NICKEL-TITANIUM ORTHODONTIC WIRES Margaret Rosen, D.M.D. Marquette University, 2016 Introduction: The initial phase of orthodontic therapy relies on flexible wires, usually composed of a nickel-titanium alloy, to apply a substantially constant load during tooth movement. Copper has been added to nickel-titanium archwires, resulting in an alloy with potential clin...
متن کاملThe Mechanical Effects of Flaming Nickel-Titanium Orthodontic Archwires
Objective: To assess the mechanical effects of nickel-titanium orthodontic archwire flaming and their distribution along the wire. Methodology: Two sizes of pre-formed austenitic nickel-titanium archwires were tested (n=10). The terminal 5mm of each wire was heated for five seconds using a butane lighter. Micro-hardness testing was used to determine the heat-affected zone for all wires. Cantile...
متن کاملSurface characteristics of retrieved coated and nickel-titanium orthodontic archwires.
OBJECTIVE The purpose of this study was to investigate the effects of oral fluids and archwire-bracket friction on the surface characteristics of NiTi alloy orthodontic archwires with/without aesthetic coating, in vivo for 2-3 months. MATERIALS AND METHODS Different cross-sections of NiTi Archwires (DENTSPLY GAC International) and Titanol Cosmetic Archwires (FORESTADENT® USA Inc.) were examin...
متن کاملThe effect of fluoride exposure on the load-deflection properties of superelastic nickel-titanium-based orthodontic archwires.
BACKGROUND It has been demonstrated that fluoride prophylactic agents may cause hydrogen absorption in NiTi wires and degrade their mechanical properties. AIMS To investigate the effect of a fluoride mouthwash on load-deflection characteristics of three types of nickel-titanium-based orthodontic archwires. METHODS Twenty maxillary 0.016 inch round specimens from each of the single-strand Ni...
متن کاملAlignment Efficiency of Superelastic Coaxial Nickel-Titanium
The preliminary phase of any orthodontic treatment with fixed appliances is the alignment and leveling of teeth. Leveling is the process in which the incisal edges of the anterior teeth and the buccal cusps of the posterior teeth are placed on an ideal horizontal level; and alignment is the lining up of teeth of an arch in order to achieve normal contact point relationship. In the alignment pha...
