Whether or not a dental revision is effective depends on the cause of the nasal base depression. If the nasal base depression is caused by the teeth, there is some effect of a dental revision, but if it is caused by the bone, the effect of a dental revision is minimal. The oral cavity and the nasal cavity have a certain degree of connectivity, but a dental revision may not necessarily improve the nasal base depression, because the method of dental revision only adjusts the tissues related to the dental area. Whether or not a dental revision is effective depends on the cause of the nasal base depression. If the nasal base depression is caused by the teeth, it can be improved to a certain extent after a dental revision. However, if the nasal base depression is caused by bony reasons, such as short chin, aging and other factors, the effect of dental revision is very little. Currently, the commonly used clinical methods to improve nasal base depression include hyaluronic acid injection, autologous fat transplantation, maxillofacial surgery and implantation of prosthesis to improve the effect of nasal base depression. Patients with nasal base depression should choose the appropriate improvement plan for themselves under the guidance of their doctors.
