What to do if the upper teeth are skeletally protruding and the chin is retracted

Everyone wants their facial features to become three-dimensional, because three-dimensional facial features can better modify people's face shape and make people look more beautiful. But not everyone can have a perfect side profile. If you observe carefully, you will find that each person's side profile is different. Some people have the phenomenon of upper teeth protruding forward and lower jaw receding. What should they do in this case?

Protruding front teeth are mainly caused by:

1. Congenital: genetic factors, parents' front teeth and jaws are more prominent, and their children may also show protruding front teeth;

2. Acquired: related to bad habits during the growth and development period, such as children suffering from rhinitis or adenoids hypertrophy, which causes nasal congestion and inability to breathe, long-term mouth breathing leading to protrusion of front teeth and retraction of the lower jaw, sucking fingers and thumbs in childhood, habitual sucking of the lower lip leading to protrusion of front teeth and tongue tilt of lower front teeth, and adults suffering from aggressive

Periodontitis can also cause protrusion of the front teeth, which has a poor prognathism.

What are the causes of buck teeth?

It is mainly caused by genetic and environmental factors.

Family inheritance: If one of the parents has malocclusion, the probability of passing it on to the children is 1/3. Many skeletal buck teeth are caused by heredity.

Acquired environment: Eating habits are also a cause of buck teeth. Children's jaws need a lot of biting stimulation when they are growing. However, parents nowadays often feed their children very fine food to make it easier for their children to digest. Without biting stimulation, the jaws do not develop fully and bony buck teeth are easily formed.

Bad habits in life: such as biting fingers and gnawing nails, can also lead to buck teeth. Also, people with obstructive respiratory diseases such as rhinitis develop the habit of breathing through the mouth, which makes the facial muscles unbalanced, the chin retracted, and forms buck teeth.

The problem of a receding chin and a protruding mouth is often treated with orthodontic treatment. By retracting the front teeth, the chin will be more visible and the side profile will be more coordinated and smooth. If there is no obvious bony protrusion or dental protrusion, they may just have a protruding mouth due to the receding chin.

Chin retraction is usually due to bone. If the child or adolescent is still growing and developing, an invisible SGTB appliance can usually be used to control maxillary development and guide the chin.

A jaw pad is formed on the posterior tooth orthodontic appliance, and the lower jaw is guided to a protruding position through the inclined surface between the upper and lower jaw pads. By gradually establishing the posterior tooth occlusion, the jaw position is stabilized to achieve the correct occlusal relationship. Then, slowly lower the height of the jaw pad until the bite is completely stable. At this point, the jaw has returned to where it should be and the chin has come out.
