Disease analysis: Buckteeth refers to the protrusion of upper and lower incisors and upper and lower jaws. In a relaxed state, the upper and lower lips cannot be closed naturally, and a large number of gums are exposed when laughing. This feature is mostly considered to be related to genetic congenital factors. Childhood is not dominant, and adolescence begins to appear. With the growth and development, it is basically stable in adulthood, and it is often more obvious after middle age due to soft tissue and atrophy.

Suggestion: The traditional orthodontics principle is to stick a nail on the tooth surface, that is, a dental appliance, and then fasten a steel wire on the nail, and use the steel wire to force the teeth to move and rearrange the teeth. It takes a long time for this method to correct adult buck teeth, and there will be a rebound.
