Background
Temporomandibular joint dysfunction is one of the common clinical conditions and is classified by the WHO as the fourth oral epidemic affecting human health. The temporomandibular joint dysfunction syndrome refers to a series of syndromes of temporomandibular joint area pain, bounce, muscular soreness, hypodynamia, mouth opening limitation, temporomandibular joint dysfunction and the like, and some cases have repeated attack, lingering and prolonged disunion, and seriously affect masticatory muscles and language functions. From the perspective of modern medicine, the cause of the disease is complex and is not clear yet. At present, the medicine is thought to be related to emotional instability, weak constitution, disordered occlusion relation of teeth, trauma and other factors of patients. These factors affect the normal structure of the mandibular joint or hinder the coordinated movement of muscles and ligaments attached around the joint structure.
The existing main modes for treating the functional disorder of the temporomandibular joint comprise a physical therapy mode, and the existing mode mainly depends on a traction device and a manual pressing of a therapist, so that the traditional Chinese medicine composition is convenient and safe, wide in application range, low in medical cost, high in cure rate and high in patient acceptance.
However, when the clinical patients have limited mobility due to the stiffness of the temporomandibular joint, the physical retractor is used to slowly open the mouth, force the temporomandibular joint to slowly rotate for a period of time, and then return to its original shape, which usually requires several treatment cycles, days, and weeks in succession. However, the temporomandibular joint requires a doctor to manually adjust the opening distance during treatment, which is time consuming and labor intensive, and may cause additional pain to the patient due to fatigue and uneven exertion of manual operation by the doctor or the user. It can be seen that the physical retractor treatment mode adopted in the current clinical application has the defects of insufficient use comfort, poor compliance and the like.
