Alveolar fracture looks very scary to the patient because there is an impact on the face, which will cause the whole face to be bloody and usually accompanied by more than bleeding, so the patient will be more nervous and feel that he/she has suffered a great deal of trauma. In reality, however, because the maxillofacial area is rich in blood flow and has a lot of vascular tissue, the injury is usually accompanied by more bleeding. A careful examination will reveal the following characteristics of alveolar process fracture. The first is accompanied by loose and dislocated teeth, because the teeth are attached to the alveolar bone, alveolar bone, alveolar fracture is usually accompanied by dislocation of the teeth, if there is a dislocation of the teeth or loss of the teeth, it is important to find the teeth in the first in the water or milk to save, and then brought to the hospital to the doctor to deal with. Secondly, soft tissue injuries can occur, including damage to the upper lip or mucous membranes in the mouth, and can lead to heavy bleeding. Thirdly, there is loosening of the teeth, which can be found not only in one tooth, but also in the bone around the tooth. These three features are typical of an alveolar fracture.
