Plot is the most common developmental disease of jaw, which affects aesthetics. Under normal circumstances, the teeth of the upper jaw cover the teeth of the lower jaw. Then the mandibular teeth extend forward, and the mandibular teeth cover the maxillary teeth. We call it jaw day.
What is the cause of the plot?
It is mainly caused by some bad habits, so there are many acquired factors and some congenital genetic factors. If parents have congenital or jaw deformities, children may also have this disease. More habits are not good. When children bite their fingers when they are young, the mandible will stretch forward and guide the mandible to develop forward. Over time, it will form a deformity. After the teeth come out, the mandibular teeth are in front and the maxillary teeth are in the back, forming a floor covering the upper teeth. Under normal circumstances, the maxilla covers the mandibular teeth, and the development of the mandible is limited by the maxilla. Now there is no power to stop the development of mandible, and the situation on land will become more and more serious.
One of the bag deformities is the prominent development of mandible, which affects people's facial morphology. A person's face looks very long, and the middle part of the face looks sunken. The second one affects the occlusal relationship. The normal occlusion relationship is affected, and the relationship is wrong when cutting food. If the occlusal relationship between maxillary and mandibular teeth is normal, it is convenient for teeth to cut food, and vice versa.
When is the best time to deal with the plot?
The sooner the ground coverage day is corrected, the better. In the early days, some simple methods can be used to prevent its further development. When this trend is found in children's jaws, we should ask doctors to make some simple devices to correct this situation. When a child begins to have teeth, we will find that it is normal that the maxillary teeth are a little outside and the mandibular teeth are a little inside after the child's teeth grow out; If the child has some bad habits, he will gradually find that the mandibular teeth move forward and gradually the mandibular teeth surpass the maxillary teeth. In the meantime, when we find that the relationship between maxillary and mandibular teeth is normal, we should ask the doctor to make a device to adjust it. There is a very simple way to make early adjustments. We can make a sling to wear on our head, which can limit the tendency of mandibular extension.
In addition, we can also make something called occlusal guide plate, which can guide the mandible to return to its original normal position when worn on teeth. In terms of time, when you find such a problem, you should try your best to do it. If the bone has been formed, for example, the child is old, then we need to adjust it through orthodontics. If it is too late, that is, after the child's jaw is developed and shaped, it can only be adjusted through surgery.
How can we prevent the occurrence of land parcel days?
As parents, we should pay attention to observe children's behaviors and habits, and be careful not to let children develop some bad habits, such as biting fingers, spoons or chopsticks, which may form the habit of mandibular protrusion in the process of biting. Once the child is found to have this habit, try to change the adjustment. When children have this habit, it is best for parents to take their children to the hospital as soon as possible and take relatively simple measures to correct them.
