The 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 کاملMechanical 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 کاملTransition temperature range of thermally activated nickel-titanium archwires
OBJECTIVES The shape memory resulting from the superelasticity and thermoelastic effect is the main characteristic of thermally activated NiTi archwires and is closely related to the transition temperature range (TTR). The aim of this study was to evaluate the TTR of thermally activated NiTi archwires commercially available. MATERIAL AND METHODS Seven different brands of 0.019" x 0.025" therm...
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 کاملEffects of three different mouthwashes on the surface characteristics of nickel-titanium and Stainless steel archwires in orthodontics
Introduction: Patients are recommended regular using of mouthwashes to control dental caries or periodontal diseases since orthodontic treatment may have detrimental effects on the tooth structures. However, chemical agents may potentially damage metal components of orthodontic appliances. The aim of this study was to evaluate the influence of three mouthwashes on the surface characteristics of...
