When teeth are deformed, most people want to improve it through correction, but do you know the difference between the Chinese wire and the round wire?In this issue, we will take a look at the orthodontic arch wire.
What's the use of nickel titanium square wire and round wire in orthodontics?
During the orthodontic process, general doctors will use three different kinds of arch wires, one is nickel titanium round wire, nickel titanium square wire and stainless steel wire.The three also have obvious differences in different periods.
1. Nickel titanium round wire for tooth alignment
2. Nickel titanium square wire is used for tooth leveling
3. Stainless steel wire is used to close the tooth space
[Nickel titanium round wire]
The nickel titanium oval arch wire is relatively soft, and it will still bounce back to the previous shape no matter how twisted it is. Therefore, when the early foundation is relatively confused, the use of the arch wire not only has a certain elasticity, but also can maintain the stability of the arch.
Round wire is usually used for early foundation and arrangement of dentition.Square wires can only be used when round wires are arranged slowly.
[Nickel titanium square wire]
There are also different types of nickel titanium square wires, which are oblate and elastic.But if it is bent, it will not rebound completely.
It can not only smooth the dentition, but also maintain the stability of the arch.When it is bent to a certain shape, it cannot rebound on its own.If a round wire is bent, it will bounce, so it cannot bend various shapes.
Like a rocking chair bow, we usually make it in the nickel titanium square wire stage to smooth our maxillary dentition.
[Stainless steel wire]
Stainless steel wire is inelastic and hard.It can maintain our bow shape and expand the bow shape. It is mainly used for closing the space after tooth extraction or the internal space of the tooth itself.
In the later stage, when we close the gap, we usually need to use stainless steel arch wire to maintain the stability of the dental arch.
The difference and function of the types of orthodontic arch wires have been completed.Let's take a look at the principle of orthodontic arch wire.
Curious about how to correct arch wire stress?
The arch wire is a force application device, and the bracket is a force transmission device.The force of the arch wire is transmitted to the teeth through the bracket.The teeth receive the power of the arch wire to move the teeth, so they are indispensable.
Seeing this, dental friends must know that the difference between the so-called square wire and round wire is that they can achieve better orthodontic effect only in the early stage and the middle stage.
