Surface Roughness of Orthodontic Archwires
LASER SPECTROSCOPY SPECULAR REFLECTANCE SURFACE ROUGHNESS WIRE
2009/2/17
Using specular reflectance, the surface roughness of six representative orthodontic archwire products was determined. Among the four alloy groups which are commonly used in orthodontics, stainless...
Friction between Archwires of Different Sizes, Cross-Section and Alloy and Brackets Ligated with Low-Friction or Conventional Ligatures
Frictional resistance Conventional brackets Archwires Low-friction ligatures
2010/3/5
Objective: To test the null hypothesis that no statistically significant difference in frictional resistance is noted when round or rectangular archwires are used in conjunction with low-friction liga...
Force distribution comparisons of various retraction archwires
Maxillary retraction Space closure Crown tip Root torque Photoelastic analysis
2009/1/23
A photoelastic study comparing the effects of the activations of three retraction arch wires used in orthodontic therapy. Schematic representations of space consolidations, intrusion and root torque a...
The effect of long-term deflection on permanent deformation of Nickel-Titanium archwires
Orthodontic wires Nitinol Spring back Permanent deformation Stress-relaxation
2009/1/23
The clinician must now consider the alloy along with cross-sectional shape and size when selecting archwires. The purpose of this study is to quantify permanent deformation after long-term deflect...
Comparisons of the thermodynamic properties of three nickel-titanium orthodontic archwires
Thermodynamic archwires Nitinol Recovery TTR
2009/1/12
The unique memory property of thermodynamic wire is only partially understood. It is believed to result from the wire's inherent capability to markedly alter its atomic bonding forces as a function of...
Frictional resistance between orthodontic brackets and archwires in the buccal segments
Archwire Friction Bracket Ligation
2009/1/9
Orthodontic sliding mechanics using preadjusted brackets is a popular approach for achieving incisor retraction. A distally directed force slides the archwire through brackets and tubes in the buc...
A review of contemporary archwires：Their properties and characteristics
Archwires Esthetics Materials Mechanics Properties
2009/1/8
The materials used by orthodontists have changed rapidly in recent years and will continue to do so in the future. As esthetic composite archwires are introduced, metallic archwires will likely be r...
The effect of short-term temperature changes on the mechanical properties of rectangular nickel titanium archwires tested in torsion
Orthodontic archwires Materials testing Torsional stiffness Nickel titanium alloys
2009/1/8
Due to their exceptional temperature sensitivity, superelastic nickel titanium wires may be affected by temperature changes associated with ingestion of cold or hot food. It has been assumed that th...
The effect of temperature on the elastic responses to longitudinal torsion of rectangular nickel titanium archwires
Archwires Materials testing Torsional stiffness Nickel titanium alloys Copper nickel titanium alloys Superelasticity
2009/1/8
To investigate responses to longitudinal torsion and the effect of temperature on the torsional stiffness of superelastic nickel titanium archwires, eight batches of rectangular wires were tested at...
The effect of cross-sectional dimensional variations of square and rectangular chrome-cobalt archwires on torsion
Orthodontic wires Materials testing Edge bevel Torsional strength Chrome-cobalt
2009/1/8
The purpose of this investigation was to study the control of cross-sectional dimensions and edge bevel by various manufacturers in the production of chrome-cobalt archwires and its effect on transm...
An investigation into the effects of polishing on surface hardness and corrosion of orthodontic archwires
Orthodontic alloys Polishing Corrosion
2009/1/7
The purpose of this study was to investigate the effect of surface roughness on the relative corrosion rates of wires of four alloys—stainless steel, nickel titanium, cobalt chromium, and beta tit...
Assessment of second-order clearances between orthodontic archwires and bracket slots via the critical contact angle for binding
Archwires Brackets Clearances Contact angles Sliding mechanics
2009/1/4
Twenty-six archwires and 24 brackets were selected from among the hundreds of products available that nominally have from 18 to 22 mil bracket slots and 14, 16, 17, 18, 19, and/or 21 mil archwire size...
Elastic Flexural Properties of Multistranded Stainless Steel Versus Conventional Nickel Titanium Archwires
Archwires Elastic properties Multistranded Stainless steel Nickel titanium
2008/12/26
Based on a recent investigation that modeled the elastic properties (ie, strength, stiffness and range) of multistranded wires made from linearly elastic materials, three-stranded (triple) and six...
Relative Stiffness of Beta Titanium Archwires
Modulus of elasticity Stiffness Nominal torque Slot play Target torque Custom prescription torque
2008/12/19
The number of vendors of beta titanium (TMA™ type) wires has recently expanded dramatically. Samples of all the available sizes were obtained from most of the major beta titanium vendors. Thre...
