Orthodontic wire: denture, ligature, diamond, nitinol

Orthodontics - this is a branch of dentistry dealing with the study of anomalies in the position of teeth, dentition, pathologies bite, studying their causes and treatment.

In this case, the devices of the factory (braces) and individual production (records, etc.). The construction uses plastic and orthodontic wire of a certain thickness.

Purpose of the product

Orthodontic wire is an important part of the orthodontic apparatus (used in children). Typically, a stainless steel product with a diameter of 0.8 mm is used. Such ligature bends quite easily, but at the same time has significant strength to move teeth without changing its shape. Has a margin of safety. It is produced in rolls 5 m long. Such an orthodontic arch is often used due to its low cost and reliability.

Varieties

Until the middle of the last century, dentistry used alloys precious metals. Only they could stay in the mouth for a long time without decomposing.

Then stainless steel appeared in medical practice, replacing the alloys of precious metals, which had greatly risen in price by that time. Wire is made from it with a diameter of 0.6, 0.8, 1, 1.2 mm. The first 2 are used in orthodontics and as ligature (for

splintingmovable teeth or the so-called arc for fillings). 1 and 1.2 mm - denture wire, is an integral part of removable dentures and maxillofacial devices. The term "diamond" is synonymous with stainless steel products.

The use of nickel-titanium alloys has found widespread use in dentistry, which heralded a new era. The alloy combines high strength and flexibility. It exists in 2 forms: M-NiTi and A-NiTi. The first was the Nitinol wire (nitinol wire). It is an M form of alloy. The second has increased flexibility and shape memory.
