Nowadays, with the development of medical technology, people’s living standards have also improved. At the same time, people are increasingly wanting to appear in front of the public with a more perfect image, which includes the need for aesthetic teeth. For some deformed teeth, I want to give them a “mass transformation”, so that they can be changed to “oblique” one by one. And this discipline has also developed, that is – Orthodontics, in layman’s terms, is “orthodontics”.

orthodontic treatment process

At present, there are many treatment methods for orthodontic treatment, among which fixed orthodontic treatment is favored due to its advantages of good retention and effective control of the direction of tooth movement. However, it has to be said that this orthodontic technique will also bring certain negative effects to the orthodontist, which cannot be ignored. Especially, when you’re almost done, that’s the last step—removing the orthodontic brackets, attachments, and thus the adhesive that sticks to your teeth.

So, why can’t we ignore the impact on enamel during orthodontic treatment? In the last step of the above treatment, if the method is not appropriate, it will cause certain damage to the tooth enamel, which is very likely to cause a series of problems such as rough tooth surface, plaque adhesion, pigmentation, and enamel demineralization. However, everyone should also know that enamel is the first line of defense of teeth and the hardest part of the human body. It can be said that it is the same hardness level as diamond, and its calcium content reaches 99.9%. However, no matter how hard the part is, after the initial damage, the subsequent damage to the enamel may gradually deepen due to many factors, and eventually, it will not be able to withstand the subsequent damage to water droplets.

What consequences will this lead to? The worst result is – a tooth filling! This is a long-term evolutionary process. Maybe everyone knows that the second line of defense after enamel is dentin, that is to say, when the enamel is destroyed, the dentin will be completely exposed, although the calcium content of dentin reaches 75%, However, dentin is even more powerless to resist the damage that enamel cannot resist. Then, if the second line of defense is breached, the third line of defense, that is, the nerves at the roots of the teeth, will all be exposed. At this time, can the teeth be sensitive?

And the culprit, traced back to the source, may appear in the process of using fixed orthodontic technology to straighten teeth. Therefore, in the actual orthodontic process, the dentist will grind and polish the tooth surface after removing the orthodontic bracket. However, although many domestic and foreign experts have conducted in-depth research on the removal methods of brackets and residual adhesive, there is still no way to determine the best solution. Because, for now, no matter what method is used, it will cause some damage to the enamel. As a result, dentists can only do everything they can to minimize damage to tooth enamel.

In the process of exploring solutions, experts found that: when removing orthodontic adhesives, tungsten carbide burs have the best removal effect, and can meet clinical polishing requirements when used alone. Better, at the same time, means minimal damage to the enamel; and if a diamond bur is used, not only does a finer polishing step need to be selected, it also places higher demands on the dentist’s technique. Specifically, some experts used SEM to observe the effects of 5 different methods of removing orthodontic adhesives on enamel, and found that the slow-speed tungsten carbide car caused the least damage to the enamel, which is an ideal method, but the operation time longer. Some experts have also found that, compared with stainless steel burs and tungsten carbide burs, diamond burs have the shortest operation time to remove tooth surface adhesives, but have the largest loss of tooth enamel. More experts put forward this view – emery burs, stainless steel burs, lasers and other methods will cause great damage to tooth enamel, while tungsten carbide burs are faster and more efficient to remove tooth surface adhesive. People in the industry generally believe that compared with methods such as emery burs and stainless steel burs, tungsten carbide burs have less damage to enamel, and are faster and more efficient.

Therefore, in order to make it work once and for all and avoid unexpected situations at the end of straightening, we can ask the dentist which bur material is used at this time. As for yourself, you can also check the information in advance to see the difference between these types of burs. After all, when it comes to dental health, everyone is equal. And if you want to have well-aligned hard to old teeth, you need to pay more attention! The elders, or dentists, have to listen to their advice – enamel cannot be regenerated, and it cannot be repaired by itself after being damaged. It can only be solved by going to the hospital for dental veneers or porcelain teeth and other means!
