What causes occlusal disorder?

summary

Malocclusion is common in daily life, which is mostly caused by external forces. For a wide range of types of disease, can be at any time, any crowd, any part of the attack. Generally, according to the different parts of the disease, it can be divided into fracture segment displacement, tooth occlusion disorder, fracture segment abnormal activity, limited mouth opening, visual impairment and other types. Because there are many types of the disease, its clinical manifestations are not the same, but generally there will be local pain, swelling symptoms, the following will introduce in detail the performance and diagnosis of occlusal disorder.

What causes occlusal disorder?

1. Displacement of fracture segment usually refers to jaw fracture. Because of the unique physiological structure of the jaw, there are often upper transverse fractures, and the fracture segment often droops due to gravity. If the direction of impact is from front to back, the fracture segment can be displaced backward to make the middle face concave; If the direction of impact is from bottom to top, it often leads to incarcerated fracture. Make the middle of the face convex.

2. Malocclusion is the most common malocclusion disorder. Malocclusion of upper and lower teeth is usually caused by jaw fracture. When the fracture segment of the maxilla is displaced downward, the maxillary posterior teeth will contact with the mandibular posterior teeth prematurely, resulting in open occlusion of the anterior teeth. If there is no displacement of fracture segment, there will be no obvious disorder of occlusion.

3. Limited mouth opening and visual impairment are also caused by jaw fractures. After jaw fracture, mouth opening is limited due to displacement of fracture segment, dyskinesia of masticatory muscle and reflex spasm; In addition, jaw bone fracture may also affect the orbit, so that eye displacement, resulting in diplopia, and eye nerve and muscle damage can also cause eye movement disorders.

matters needing attention

Finally, it is necessary to remind the majority of patients that they must cherish their body in daily life, always pay attention to their health, and seek medical treatment immediately in case of discomfort, so as to prevent missing the best treatment opportunity.
