The wall of "noticeable, painful, cannot be removed" that prevents orthodontics

Now that it is about two years as a corona. Overseas, there are some places where you are about to end your long -lasting mask life. In the near future, the days of removing masks and doing business with overseas people may come back. It is often said that the human expression is read "Japanese people in the eyes" and "Westerners are in the mouth", but in Europe and the United States, the mouth is quite important. If you take a mask, the opportunity to see your mouth will increase again. In Europe and the United States, correction of teeth is one of the social status. It is considered that white oral alignment is connected to cleanliness and the presence of culture. By all means, you want to treat you with a good impression. However, there are many people in Japan who say "I don't want to see the orthodontic device". Certainly, wire treatment is noticeable and painful, and once attached, it cannot be removed basically until the treatment is completed. There is an orthodontic treatment called "Invisaline" to hit those who hate these negative points.

What is Invisaline?

■ Invisaline is an invisaline that is "invisible, less painful, removed" is a treatment that uses a transparent mouthpiece (= aligner). There are dozens of custom -made alignments. It is a system that moves the teeth little by little by replacing the second one after 7 to 10 days after attaching the first piece. Even if you wear a transparent aligner, you will hardly notice it from others. Because there is no metal, it can not hurt your cheeks and tongue, or sudden pain. You can also enjoy your meal as usual because you can remove it. In 1999 in the United States, full -scale sales in Japan in 2006, and as of October 2020, more than 9 million people have been treated by more than 100 countries around the world. It is a relatively new treatment and is still evolving. Some people think that the treatment period will be longer because it seems to be easier to receive than wire treatment, and some people think that wire treatment may be better. I will emphasize. Of course, some patients can only be treated with wires, but there are many patients who can definitely recommend Invisaline. An important point is to understand the advantages and disadvantages of the two and entrust the treatment to orthodontists who can judge which treatment is more suitable for you. By the way, the aligner needs to be worn for 20 to 22 hours a day. Since it is worn at least 20 hours a day, it will always be a life that always uses the aligner except for meals and brushing. This is the only disadvantage of Invisaline. For those who are troublesome or forgotten and are not confident in the wearing time, the Invisaline may be rather unsuitable. The number of alignments is 20 to 30, and up to 99 pieces are created for those who extract and correct. If you exchange one week a week, 52 pieces will be treated for about one year. ■ "Beautiful teeth arrangement in a short period of time without tooth extraction" In the past, it was not possible to correct without a healthy teeth. By simulating the IPR (Inter Proximal Redaction) under mm or less, you can get beautiful teeth in a short period of time without extracting teeth. The IPR refers to the enamel of the teeth up to 0.25mm on one side and up to 0.5 mm between the teeth. The thickness of the enamel varies depending on the teeth and parts, but it is reported to be around 1mm in the part where the IPR is performed, so it can be said that it is a safe range even if 0.25mm is cut. Furthermore, not to extract teeth, the distance traveled to the teeth is reduced and the treatment period has been shortened. Even those who have difficulty in correction if they do not extract teeth have been increasingly treated by Invisaline. ■ "Out teeth" are also improved with high probability ... Invisaline is recommended, and unsuitable open bite (open bite) is more suitable for Invisaline than wire orthodontics. Here, it refers to a tooth position that is open byte due to the position of the tooth, and excludes skeletal factors. Open byte is a state where the back teeth are bite, but the front teeth do not bite up and down, and the front teeth cannot bite. It is possible to retract the "out teeth" with a considerable probability. The difficult thing is when the bite of the front teeth is quite deep. If the lower front teeth are hidden in the upper front teeth when you say "e", we do not recommend treating them alone. In addition, it is difficult to respond to the request of losing the molars with tooth decay, but moving other teeth to fill the gaps. However, now, about 80 % of patients who have been consulting our hospital for orthodontic consultation have been expanding to the recommendation of Invisaline treatment.
