Hello, dental plastic surgery generally refers to traditional braces. Of course, lingual braces have developed now, but the principle is the same. They all rearrange their teeth with the help of external forces. It takes a long time to correct braces, generally about 2 years, and the best operation time is 12 18 years old, which has a good effect on odontogenic buck teeth and ground covering, but the alveolar buck teeth and ground covering braces can not achieve the expected effect and must be corrected by surgery.
