The chin recession belongs to the deformity caused by the receding jaw, so the jaw is short and small, the appearance is like a “bird’s mouth”, the age to correct the chin recession can not be generalized, need to see which cause the chin recession. Usually the main causes of chin recession are dental malocclusion or jaw bone dysplasia, different causes of chin recession, the best age for correction is not the same: 1, dental malocclusion: If the upper teeth are caused by dental malocclusion, visually the phenomenon of chin recession will arise. In this case, orthodontic treatment can be performed after the permanent teeth have been replaced during adolescence, and orthodontic appliances can be worn to relieve the receding chin. Usually can be selected at the age of 11-15 years, this is due to the teeth before the complete development of bone orthodontics, chin recession relief effect is more good; 2, jaw bone dysplasia: bad biting habits may affect the development of the jaw bone, if found in early childhood or juvenile chin recession, can be in early childhood or juvenile bone is still in the process of growth and development, timely correction of bad posture, the chin recession. The receding jaw may be relieved. If the jaw is severely stunted, which affects the normal chewing function, orthognathic treatment is required after the growth has basically stopped, i.e. after 18 years of age. In general orthognathic surgery requires preoperative imaging, blood sampling and other tests, and then a surgical plan is made under the guidance of a dentist, depending on the degree of chin recession. In addition, if you only feel that the receding chin affects the aesthetics and does not affect the normal chewing function, you can also undergo facial adjustment through medical aesthetic methods such as filling prosthesis, hyaluronic acid injection, osteotomy and orthopedic surgery in adulthood. However, it should be noted that any surgery has a certain degree of risk, so you should try to choose a regular medical institution when you visit.
