Please go directly to this website to find a professional orthodontist: http://www.cos-china.org/s_doctor.php This is the doctor search page provided by official website of China Orthodontic Society, where you can find the list of specialist members of China Orthodontic Society in various places. At present, there are only the first batch of certified doctors, and there may be the second and third batch of certified doctors in the future. In foreign countries, orthodontists must undergo orthodontic training after graduation before they can legally engage in orthodontic treatment, otherwise it is illegal. At present, there are a large number of orthodontic patients in China, but only 10% orthodontists are qualified professional teams, which makes people worry about where the protection of orthodontic treatment in China is. Please choose your orthodontist carefully. If the occlusal function cannot be established through orthodontics, it will lay a great hidden danger to the future oral health, and we should not only pay attention to neatness and lose health.
