Orthodontic Research

Decent Essays

The first idea of orthodontics has come when finger pressure manifested tooth movement. With the development of this branch of dentistry, there is constant research to create appliances which can move teeth “ideally”
This has led clinicians trying to specify many appliances able to move the teeth, most of them include wires. Wires in many shapes, sizes, and materials (metallic alloys) are typically part of the orthodontist's inventory.

Wires, and auxiliaries fabricated from wire (helical closed-coiled and open-coiled, uprighting,and rotating springs) can make dental displacements through delivering force or simply through carry force from one location to another within the dentofacial complex.It also may prevent unwanted tooth movement.
Wires have a fundamental role in active and retentive orthodontic therapy. Wires may …show more content…

Before the development of orthodontic brackets, the arch bow was often threaded at its ends and passed through tubes joined to bands encircling the terminal molars, with nuts placed mesial or distal to the tubes depending on the activation required
The arch bow was activated by tightening the nuts
Localized auxiliaries were launched from the arch bow but because of its stiffness, the arch bow could not perform individual tooth movements or leveling processes(image 1)
A modification was joining of hooks to individual bands and the rolling of round arch bow wire to create a ribbon with cross-sectional dimensions of 0.02x0.05”, the objective being to produce bodily movement and faciolingual displacement(image 2)

Angle’s pin and tube appliance:

Bands with vertical tubes are cemented to the teeth and an archwire with soldered vertical pins is adapted to the arch
As the teeth move, the archwire is formed to a more ideal shape (image
