No harm to teeth, it is the first choice of many students.

Generally, upper lip protrusion is caused by maxillary protrusion. Therefore, to correct the upper lip protrusion, it is necessary to correct the maxillary protrusion. It is suggested to go to the stomatology department of a regular hospital or the orthodontics department of a big hospital for examination of curved surface tomography and lateral head film, and at the same time carry out projection measurement. Through projection measurement, it can be judged whether it is maxillary protrusion, mandibular retraction, maxillary protrusion and mandibular retraction, maxillary protrusion in the front or the whole maxillary protrusion. If the maxillary protrusion is slight, it can be corrected by orthodontic treatment, that is, pulling out some teeth with less function and then retracting the maxillary anterior teeth inward, which can solve the problem of maxillary and tooth protrusion. If the maxillary protrusion is serious, orthognathic surgery may be needed. At present, there is Lefort osteotomy in orthognathic surgery, that is, pushing the whole maxilla backward. You can also perform osteotomy on the front of the maxilla and push the front of the maxilla backward without moving the occlusal relationship of the posterior teeth.
