The cheapest is the traditional steel braces. It takes about 1.2W to make them now. If the materials are imported, the price will be more expensive, even up to 2W.
Followed by ceramic braces, the price is about 2.5W
Then the most expensive ones are transparent braces and lingual braces, which are completely invisible and beautiful, and have advantages in both time and comfort. For example, the correction time of eBrace personalized lingual correction is about 1/4 faster than that of ordinary braces, but the price is more expensive, at least 3.5W
At the same time, the price of orthodontics also has a great relationship with the level of doctors and hospitals you choose.
I'm not familiar with Langfang, but it's not bad to find a regular hospital clinic.
