I have a jutting chin

A chin whose lower chin is projected forward than the upper chin is called a jutting chin. Not only the level of crossbite is severe but also lower teeth are much projected forward than the upper teeth. A long chin without the crossbite is not called a jutting chin but a long chin or a long face. In Korea, there are many people with a jutting chin, but for Westerners, the lower chin is smaller in many cases. There is no physical difficulty due to a jutting chin. The major purpose of the treatment is to balance the overall face by correcting the shape of face to a state with harmonized face bone.

A jutting chin is inherited, the excessive growth of lower chin

The reason of having a jutting chin is the excessive growth of the lower chin compared to normal growth. The size or shape of a chin can be inherited if there is a relative whose chin is jutted, there is a possibility. Also, if pushing the lower chin forward becomes a habit since childhood or an abnormal operation of muscles that are connecting the upper and lower chins may cause a jutting chin.

The perverse impression is because the lower teeth are projected forward than the upper teeth

The occlusion state of normal teeth is that the upper teeth slightly covers the lower teeth as it is projected forward than the lower teeth, but in a jutting chin the relationship of teeth is opposite to the normal occlusion. In other words, the lower teeth are projected forward than the upper teeth. It is tested by seeing the occlusion state of closing lips naturally. If one often hears ‘You are like a witch in the Snow-white,’ a jutting chin is suspected. If it is not serious, some would hear having a stubborn or strong impression.

The treatment is a combination of orthodontics and surgery

For children who are in the growing phase, an orthodontic device to suppress the growth of the lower chin can be used. However in general, the growth lasts up to 16 to 18 years old, thus, wearing an orthodontic device until such age is hard for children. Once growth is finished, orthodontics and the jawbone surgery can be done to get a fruitful result in aesthetic as well as orthodontic aspect.

The process of the jawbone surgery

* 1st step - the orthodontics before surgery
The orthodontics before the surgery is a preparatory step for the jawbone surgery that prepares for the upper, lower, back teeth to fit well after the surgery. In general, it takes about 6 months to 1 year.

* 2nd step - the surgery
for the jawboneIt takes about 3~7 days of hospitalization.

* 3rd step - the orthodontics after surgery
Finally, the orthodontics after the surgery is a step to arrange the newly moved jawbone and the teeth, which is more like a step for a touch of detailing. It is necessary to consult with an orthodontist for the orthodontics and a cosmetic surgeon who is an expert in facial bone surgery for the surgical part. It is recommended to find a specialized clinic that provides a medical treatment of both orthodontics and facial bone surgery through specialized cosmetic surgeon.
