Occlusal disorder

Dental occlusion disorder: The occlusal relationship between the upper and lower teeth is often disordered due to the displacement of the jaw fracture segment. This is the most obvious symptom of jaw fracture and is of great significance in the diagnosis of jaw fracture. Transverse fracture of maxillary bone, the fracture segment is shifted downward, so that the maxillary posterior teeth and the mandibular posterior teeth are brought into early contact, and the anterior teeth are in an occlusal state. After a mandible fracture, the teeth are often disorganized due to displacement of the fractured segment. If there is no displacement of the fractured segment, there is no obvious disorder in the occlusion of the teeth.
