The reason for the lower jaw being forward
As mentioned, the protrusion of the lower jaw has a genetic basis, and no matter how strong the genes that cause this jaw abnormality are, this abnormality starts at a younger age and will naturally continue until the complete completion of growth (which is around 17-18 years old). had The more the protrusion of the lower jaw shows itself at a younger age (for example, during the period of milk teeth), it means that it has a very strong genetic background and the condition will worsen until the growth is completed.
Treatment of anterior lower jaw in children
As soon as many parents notice that their children's lower jaw is forward, they expect that this problem can be solved by visiting orthodontics early. But the reality is that this issue is an exception among orthodontic problems. In the past, it was said that this issue can be solved with a chin strap, and of course, some orthodontic specialists still use this device. But the results of the studies of the last few years have shown that this device (especially in our race) has no effect in preventing the growth of the lower jaw, and if the lower jaw is supposed to grow (there is a genetic basis for it), this jaw will continue to grow until the growth is complete. It does and its growth cannot be stopped. Many people who have used this device in the past, after finishing the growth and looking for its ineffectiveness, have been looking for other treatments. It probably has a very strong genetic background, and it is better to wait until the age of 17-18 to treat it.
Protrusion of the lower jaw or recess of the upper jaw?
Of course, there is a possibility of success for the treatment of mandibular protrusion at the age of 8-11 years, which is a condition in which the lower jaw itself is not backward and looks forward due to the indentation of the lower jaw. In this situation, it is necessary to make sure that the person does not have a genetic history of protruding lower jaw (no one of his relatives has a protruding lower jaw), because if it is misdiagnosed and the problem is caused by protrusion of the lower jaw rather than indentation of the upper jaw, initial success in the treatment With the next growth, the lower jaw will be neutral and the result of the treatment will be ineffective. Of course, the probability that the problem is more in the upper jaw than the lower jaw in these abnormalities is 25%, and the recommended treatment for this upper jaw indentation is the facemask orthodontic device.
