Is the orthodontist Hou really credible? Who did it at his house? How much does it cost to perform surgery on maxillary protrusion? Not particularly strict.
It is deceptive, risky, slow in later recovery, easy to damage the tooth nerve, leading to early osteoporosis, lifelong toothache and other serious sequelae. Be sure to go to a professional dental hospital. In your case, you can do it through jaw surgery, and the effect is quite good, and the cost is below 50 thousand.
