1. Of course, the best is your Guiyang Stomatological Hospital (Guanxing Road, Guiyang 18), which can be said to be the authority there. With Shanghai Jiaotong University Stomatology and Zunyi Medical College Base as auxiliary units, the manpower and material resources are quite abundant. As for the price, it is generally around 7000 yuan, but it depends on personal circumstances (taking pictures). 2. Because the course of orthodontic treatment is about two years, it needs to be visited once a month, so local treatment is recommended. 3. The general process is: X-ray+dental model-make a plan and plan tooth extraction (whether tooth extraction depends on the situation)-tooth extraction. Replace the archwire-wear the retainer for at least half a year after treatment. At present, your age is basically in line with the best age stage. Finally, I would like to remind you that it is best to make a plan for orthodontics, because every doctor has different ideas, and the plans made by other doctors may not be implemented.
