Personally, braces belong to a kind of memory steel wire, which is divided into three categories: domestic, joint venture and imported. The cheapest domestic, the most expensive imported!
But for this kind of memory steel wire itself, there are many factors that can be subdivided, such as the material department and so on! I heard that there is an invisible memory line.
This kind of steel wire is hard to find because of its high transparency, giving people a hidden effect! It is estimated that the scope of orthodontics in Chongqing is several hundred to several thousand yuan!
If the landlord has other questions about orthodontics, you can go.
