The cost of orthodontics varies mainly according to the degree of malocclusion of patients and the orthodontic equipment and methods selected by patients themselves. At present, there are two kinds of correction methods widely used in clinic: one is invisible correction, which is loved by more and more young people because of its good aesthetic performance and does not affect the daily life and social function of patients. The cost of invisible correction is relatively high, about 30,000-40,000 yuan, and the correction effect is relatively good, and the correction time is about 2. Second, the metal bracket has a long history, good correction effect, relatively low cost and high cost performance, and the cost is about1-20,000 yuan. It is suggested that patients go to a regular hospital to consult a professional doctor and choose a correction method that suits them.
