The method of resetting the dislocated mandibular joint is usually chosen as the intra-oral method. The intra-oral method usually involves the operator being located in front of the patient, wrapping gauze around the thumb, penetrating deep into the patient’s mouth, placing it on the jaw surface of the mandibular molar as far back as possible, pressing the mandible downward with the thumb, and then slowly pushing it upward, at which time some can hear a popping sound and can be reset to its original position. You can also choose the extra-oral method, put the thumbs to both sides, protruding from the front edge of the condylar branch below the zygomatic arch, and then slide backward into the joint fossa and get reset. After reset, it needs to be fixed for use, and the elastic bandage is fixed to restrict the teeth to go up and down together, and the degree of mouth opening is generally controlled within 1cm, and it is recommended not to eat harder food, and it is recommended that the restraint time is generally adhered to for about 20 days, so that the recent relapse can be avoided as much as possible.
