The jaws, the bones and muscle tissue that make up the upper and lower parts of the mouth. The upper part is called the maxilla and the lower part is called the mandible The bone of the jaw is the jawbone. It is divided into the maxilla and mandible. An abnormal protrusion of the jaw bone is called a jaw bulge. So what diseases should be diagnosed differently from jaw bulge? To pay attention to the following diseases to distinguish the diagnosis: jaw bone cyst: refers to a cystic swelling containing fluid in the jaw bone, gradually increasing in size, expansion and destruction of the jaw bone, according to its pathogenesis can be divided into two categories of odontogenic and non-odontogenic, odontogenic, that is, cysts evolved from adult teeth or teeth; non-odontogenic cysts can be formed by the development of epithelium remaining in the jaw bone during embryonic development, such as facial cleft cysts, but also for injury Non-dental cysts can be formed by the development of epithelium left in the jaw bone during embryonic development, such as facial cleft cysts, but also injury-induced extravasation cysts and aneurysmal bone cysts. Excessive jaw development: It is the clinical manifestation of anterior teeth retrusion. Mostly due to local obstruction in the process of tooth eruption or replacement, it is often manifested as simple anterior teeth retrusion. The anticlinal coverage is small, and the molar correlation is neutral or close to neutral correlation. The morphology and size of the lower jaw are basically normal, and there is no obvious abnormality in the maxillary and mandibular relationship, the chin does not protrude forward, and the face is basically normal. There is no morphological or structural abnormality in the bones as measured by X-ray cephalogram, which is easy to correct and has a good prognosis. Tooth-like hard tissue in the jawbone: It is commonly found in odontoma (oral and maxillofacial surgery), which is a tumor of dental origin growing in the jawbone and formed by one or more abnormal development of dental embryonic tissue, and may contain various dental embryonic tissues or teeth at different stages of development. It may be irregular in shape, may resemble a normal tooth, or may have no tooth shape, but is just a disorganized mass of hard tissue, surrounded by a fibrous membrane, with irregularly arranged enamel, dentin and bone under the microscope. Early diagnosis and early treatment are extremely important. Those who are left with misaligned teeth or maxillofacial deformities should wait for future orthopedic treatment.
