If the jaw is knocked to the point that the teeth can not be closed up and down, it is considered to be dislocation of the temporomandibular joint, loose teeth, fracture of the jaw, etc., which can be treated by resetting and fixing the teeth.
1. Temporomandibular joint dislocation: if the jaw is knocked to the temporomandibular joint dislocation, it will cause difficulty in closing the mouth and swallowing, the main treatment method is to reset the jaw by manipulation, and then use a bandage to brake, and can be reset by surgery if necessary.
2. Loose teeth: If the jaw is knocked and touches the teeth, it will cause the teeth to be loosened, which will lead to the inability to close the mouth. If the crowns and roots of the teeth are intact, and the teeth are only loosened to a certain extent, the teeth can be reset, and the teeth can be fixed in the alveolar fossa through the methods of arch splint fixation, periodontal splint fixation and orthodontic tray fixation, etc. The main treatment method is manual reset, followed by bandage braking, and if necessary, surgical reset.
3. Mandibular fracture: If the jaw is knocked to the jawbone fracture caused by the upper and lower teeth can not be healed, can be fixed through the single jaw or intermaxillary fixation and traction reset and other methods of treatment.
There may be other reasons for the teeth not closing when the chin is knocked, so it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or standardized treatment.
