Abstract:

Orthodontic tooth movement is a physiologic response to externally applied forces; the motive forces are primarily mechanical. The optimal application of orthodontic force enables maximum movement of teeth with minimal irreversible damage of the periodontal ligament (PDL), alveolar bone, and teeth. Since arch wires are the main force system in orthodontics, it is important in clinical practice that they deliver appropriate, predictable and repeatable forces during treatment. These specialized wires even promise shape memory properties and the possibility of super elastic behavior, which signif

Abstract:

ABSTRACT Tooth movement in orthodontic therapy is connected to the frictional force that is created as the wire passes over the bracket. It is possible for teeth to move quickly when friction is at a minimum. Wires coated with nanoparticles have been found to reduce friction as a result of current developments in the orthodontics sector. Having an antimicrobial property is an added benefit. To reduce the friction generated by brackets, wires, and bands by lessening their cytotoxicity, this study examines the potential use of TiO2 nanoparticles in orthodontics. A monolayer of L929 was utilized

Abstract:

Today orthodontic treatment is in growing demand and is not limited to a specific age or social group. The nature of orthodontic treatment is such that the orthodontic wires and appliances, which are used to apply force and move the teeth, are exposed to the oral cavity. Shaping and replacing these wires in oral cavity are the major assignments of orthodontist on appointments. Therefore, we can say that orthodontic treatment requires working with dangerous tools in a sensitive place like oral cavity which is the entrance of respiratory and digestive systems.

Accordingly, acquiring adequate knowledge about these approaches' clinical applications and biochemical behavior is essential when planning for a successful orthodontic treatment.

Abstract In Australia, the history of materials engineering for orthodontic wires is generally related to the development of the Begg appliance. Therefore, until recently, it has helped in the search for light resilient forces produced by fine high-tensile stainless steel wires. Recently there has been added the desire to include wires of a low modulus of elasticity which also produce light forces but in larger diameter rectangular wires. There have been three periods of development, namely, up to and including the Second World War, up to Dr Begg’s passing, and subsequently. A general metallur

Abstract:

The leaching of metal ions from orthodontic appliances is a problem for their use in patients with metal allergies. Despite the development of a number of non-metal orthodontic appliances, including brackets, non-metal wires are not yet available. Therefore, it is necessary to modify the surfaces of orthodontic wires to prevent the leaching of metal ions into the oral environment for use in such patients. This study was performed to examine whether plating of orthodontic wire with titanium nitride (TiN), which does not impair its mechanical properties, could prevent the leaching of metal ions

Abstract:

Corrosion has been found to be the predominant cause for the failures of many metallic orthodontic archwires. Corrosion occurs due to the loss of the metal ions into the solution directly or due to the protective surface oxide layer degrading slowly. There is a simultaneous oxidation and reduction process taking place also called as redox reaction. Corrosion causes a breach in the protective oxide films which enables the beginning of the corrosive process. With evolution in metallurgy, different types of orthodontic archwires have come into use which has different physical and chemical propert

Abstract:

The release of ions is the initial stage of the corrosion process in an orthodontic wire. Continuous release of ions can reduce the effectiveness and performance of the orthodontic wire. Continuous release of ions in CuNiTi orthodontic wire can change the properties of the wire and trigger hypersensitivity reactions, also in stainless steel orthodontic wire which experiences continuous release of ions can reduce its stiffness. The tannin in avocado seeds is useful as a corrosion inhibitor it can inhibit the release of ions because they are able to bind with metal ions and form a passive layer

The system uses heat-treated wires with better physical properties such as hysteresis when is compare with traditional wires. However, the FLOWJAC® technique doesn´t use a wire sequence to get a “working wire”, just a 0,014 Copper NiTi.
