Assessment of frictional resistance and surface roughness in orthodontic wires coated with two different nanoparticles

Microscopy research and technique (Print), 2022
Several mechanical and biological factors may change the orthodontic wire frictional resistance (FR). Titanium dioxide (TiO2) and silica dioxide (SiO2) nanoparticle (NP) coatings may be used to improve the characteristics of materials, reducing FR ...

Antiadherent and antibacterial properties of TiO2-coated and TiO2:Ag-coated stainless steel orthodontic wires against S. mutans bacteria

Acta of Bioengineering and Biomechanics, 2022
Purpose: Conventional orthodontic treatment with stainless steel orthodontic wires may be detrimental to oral health, as it contributes to demineralized lesions and increases adhesion and bacterial biofilm formation, which contributes to cavity ...

Tensile properties of orthodontic wire

American Journal of Orthodontics, 1977
1. Wires with a range of tensile properties are available for construction of a Stage 1 arch wire in the Begg orthodontic appliance. 2. Over a period of 3 days, a detectable amount of stress relaxation occurs in some orthodontic wires loaded initially to 20 kg.

Comparative range of orthodontic wires

American Journal of Orthodontics and Dentofacial Orthopedics, 1986
ADA specification No. 32 for determining the range (elastic limit) of orthodontic wires uses the bending of a wire section treated as a cantilever beam. An alternative method for defining the range of orthodontic wires proposed by Waters (1981) is to wrap wire sections around mandrels of varying diameters and measure the deformation imparted after ...

The corrosion of orthodontic wire

The European Journal of Orthodontics, 1988
The corrosion of stainless steel orthodontic wire was investigated using the electrochemical technique of polarization resistance. A potentiostat was used to apply small perturbations about the corrosion potential and the resultant current was measured.

Force relaxation in orthodontic arch wires

American Journal of Orthodontics, 1984
Wire selection for use in an orthodontic appliance is usually based upon clinical impressions. This is unsatisfactory. A far better basis for selection would be measured values of the forces exerted by the arch wire, both initially on insertion of the appliance and their variation with time as a result of tooth movement and of stress relaxation in the ...

Orthodontic wire: a continuing evolution

Seminars in Orthodontics, 1997
Wires have substantial structural presence in active and retentive orthodontic therapy. Wires, and auxiliaries fabricated from wire, may deliver force to produce dental displacements, they may attempt to prevent unwanted displacements, or they may simply carry force from one location to another within the dentofacial complex.
