The reason why they are divided into several different types is mainly to deal with different degrees of malocclusion. If it is a complex tooth deformity problem, it is suggested to choose double-membrane invisible braces, which will have better orthodontic effect and efficiency. If the problem of malocclusion is simple, teeth can be aligned in 20 sets of braces, and orthodontists will recommend comfos, which is not only cheap, but also efficient.
Regarding the cost of angel correction, Zheng Fujun can share it with friends here: most dental hospitals or dental clinics pay the cost of braces in one lump sum, and the rest of the dental treatment costs can be settled according to the number of times or after treatment. But not all dentists are like this, so be sure to communicate with orthodontists in advance.
