[Risk prevention and control of facial esthetic defects during orthodontic treatment].

Facial aesthetic defect is obviously different from facial aesthetic standard. Orthodontic treatment may expose or even magnify other facial aesthetic defects while solving patients' main problems. There are many aesthetic traps in facial bone structure, soft tissue and teeth. Orthodontists should comprehensively recognize patients' dentofacial aesthetic defects. When solving major problems, we should keep an eye on the changes of minor problems and other uncontrollable factors. Potential risks should be clearly recognized and prevented.
