A chin that is too far forward is clinically defined as a mandible that protrudes forward, and is usually treated with orthognathic surgery. A chin that is too far forward indicates that the upper jaw is tucked inward relative to the lower jaw, and therefore can be caused by two things, an ingrown upper jaw and a protruding lower jaw. Changes in the position of the bones are still primarily treated by orthognathic surgery to correct the relationship between the patient’s upper and lower jaws. This is done primarily through osteotomies and moving the bone mass. It is also usually necessary to work with orthodontic treatment to ensure that the teeth are in good occlusal relationship. It is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
