Hello, classmates! It is not too late to do it now. Like you, I began to make corrections after work. I installed the stent in May last year, and the doctor said that the stent can be removed around 10 this year. As far as I know, there are two kinds of invisible stents. I use ceramics, although I can't see it, I can still see it when I get close. You can see this in Baidu pictures. There is also a kind of dental tray, which is said to be installed on the inside of teeth. This kind of bracket is basically invisible, but it has many shortcomings, poor effect, uncomfortable mouth and the most expensive price. The effect of steel wire support is actually the best, but it's really not good-looking. As for the price, it depends on the size of the region and the hospital. I did it in Suzhou, which is basically the best stomatological hospital in Suzhou. The treatment cost from beginning to end is about 10. Shanghai is about 20 thousand (money doesn't have sex at once) I'm talking about the price trend of regular hospitals. Orthodontics is not a very complicated technology now, so there is no need to blindly find an authoritative one, but you can't just find a workshop. . . If you do this, you must be patient. The treatment cycle is long and the process is still painful. Before correction, you need to pull out your teeth (rearranging your teeth requires enough space to adjust, so you basically need to pull out your teeth), and you should also pay attention to your diet (I just don't listen to the doctor, brackets often fall out, hehe). In short, it is miserable! Ha ha ha, but it's finally worth it! The whole treatment cycle is generally like this (filming the model-extracting teeth-installing brackets-adjusting dentition-closing teeth (I have reached this point, and I need to go to the hospital once a month for the two stages of dentition adjustment and closing teeth)-taking off brackets and putting on retainers (it may take 24 hours at first, and then I can stop using them gradually). You know why.
