What is the earth-shaking world? The earth-blocking sky is also known as the anterior teeth, the lower teeth cover the upper teeth, the chin is extended, and the face is "crescent-shaped". If the earth and earth do not appear, it will be corrected in time. The longer the time, the more difficult it will be for treatment, and it may even affect the development of jaw bone in the future. Why does
appear? In addition to innate factors, parents or themselves should also pay attention to some bad habits.
1. Incorrect feeding during infancy and toddlers. This is because when the child lies flat on his back, he drinks the bottle upright, or sits straight and lifts the bottle too high, the child will actively stretch his jaw forward in order to successfully complete the swallowing movement, which will lead to "the earth and the sky".
Therefore, parents should adopt the correct artificial feeding posture, the baby sits straight or semi-lying, the nipples and facial features should be 90 degrees as much as possible, and the bottle should not be lifted or tilted more than 45 degrees.
2. There are bad habits such as finger sucking, lip biting, and tongue sticking out. When parents find that their children have such behaviors, they must correct them in time to avoid the later formation of mishap deformities such as earth-covered and sky-high.
3. Local disorders in the dental period. Some dental problems during the dental replacement period, such as deciduous teeth retention or premature loss, insufficient wear of the nasal teeth, congenital loss of upper permanent incisors, etc., may also cause earth-covered obstruction.
4. Caused by physical diseases. Due to chronic inflammation of palatal tonsils or lingual tonsils, the mandibular protrusion can stimulate the mandibular protrusion over time, which can lead to the anterior teeth reversal and mandibular protrusion . In addition, postoperative cleft lip and palate surgery, rickets , endocrine diseases, etc. may also cause mandibular protomy deformity.
If you encounter the above problems, parents should not only correct their children's bad habits, dental problems or physical diseases in their lives, but also go to the hospital for treatment in time. Don't delay the condition ~
