If you want to have a complete mandible, go to Hangzhou Stomatological Hospital. That's what I did. Prices there are relatively high, but the environment is OK. If you want to do a half-mouth, that is, only the upper jaw or the lower jaw, you can choose Zhejiang Stomatological Hospital or Zhejiang II.
But you should consider it clearly, because the corrected teeth are easy to loosen (old age). And not once and for all. These all depend on the degree of running-in of teeth. You can ask the doctor first. And the choice of hospital depends on the traffic situation in your home.
