Hello, there is not much difference between the two. The main basis of orthodontic expenses: 1. Different ways to choose orthodontics have different prices. There are ordinary orthodontic techniques, invisible orthodontic techniques and semi-invisible orthodontic techniques. 2. The degree of tooth crowding is different from that of jaw development, that is, the complexity of correction is different and the price is different. 3. Age: The correction of younger patients is simpler than that of older patients, and the correction cycle is shorter, so the price will be cheaper than that of older patients. At the same time, different price standards in different regions will lead to different prices. The cost ranges from 5,000 yuan to 50,000 yuan.
