Alveolar type
Introduction
Introduction The alveolar process lesions begin to destroy the bone from the alveolar process. In severe cases, the teeth are completely buried in the soft tissue, the teeth loose, fall off, and the bleeding of the gums presents a 'floating' sign. Some bone destruction is extensive, the edges are blurred, similar to changes in malignant tumors.

Causes of alveolar process
1, the most common tuberculosis in the jaw, more secondary to other parts of the body of tuberculosis.
2, often caused by sputum in tuberculosis patients or tubercle bacilli in saliva, through the oral mucosal ulcer or through the pulp extraction of the pulp directly into the jaw, can also invade the jaw through the blood circulation caused by jaw tuberculosis lesions.

Maxillofacial features
Alveolar process
A history of tuberculosis such as open tuberculosis can be found. The patient's sputum or local secretion smear may be found in tuberculosis, and the X-ray film shows obvious bone destruction, and the edge of the lesion is blurred and irregular. In the mandible, a cyst-like cavity can be formed with a little periosteal new bone formation. Note the differentiation from suppurative osteomyelitis and jaw malignant tumors. A biopsy can be performed if necessary.

Alveolar edious symptoms
Dislocation of the tooth: under the impact of a large violent attack, the tooth may be partially or completely dislocated. Due to the tear of the periodontal membrane, even the neurovascular bundle entering the pulp from the apical foramen also tears, and the tooth is loosened and tilted clinically. Elongation and pain, hinder chewing. When the teeth are completely dislocated, the teeth are separated from the alveolar socket, or only the soft tissue is connected, often accompanied by gingival tears and alveolar bone fractures.
Toothy teeth are a cosmetic feature. Also called the upper and lower jaw protrusion, bird's beak deformity, sudden jaw deformity and so on. The upper and lower incisors and the upper and lower jaws protrude forward. In the relaxed state, the upper and lower lips are not naturally closed, and the gums are exposed a lot when laughing. The open lip is exposed from the front, and the nasolabial fold is deep. The contour of the face is viewed from the side to protrude excessively forward from the lip to form a ">" shape. Severe cases appear dark, yellow or even chapped due to long-term exposure of the teeth.
Tooth displacement: When periodontitis develops to a certain extent, the teeth tend to tilt toward the more severely damaged side due to the destruction of the alveolar bone of the fixed teeth. If the condition is mild, the alveolar damage is not much, the teeth are not loose, and the teeth can be restored by orthodontics after controlling the periodontitis. If the condition is severe, the alveolar bone damage absorbs more than 1/2 of the length of the root, and if the tooth is loose, the tooth cannot be reset.
The diagnosis of this disease is mainly based on clinical manifestations, and the history of tuberculosis such as open tuberculosis can be found. The sputum or local secretion smear of the patient may be found in tuberculosis, and the X-ray film shows obvious bone destruction, and the edge of the lesion is blurred. neat. In the mandible, a cyst-like cavity can be formed with a little periosteal new bone formation. Note the differentiation from suppurative osteomyelitis and jaw malignant tumors. A biopsy can be performed if necessary.
