Symptoms of temporomandibular joint disorder syndrome?
summary
I believe many people have experienced mandibular joint pain. It's a kind of disease that is difficult to cure. When they are talking or eating, they suddenly feel that their joints are stuck and can't move. What's more, they can't open their mouth, or they have masticatory pain. When the degree is light, they can relieve themselves. Many people can't cure it for a long time, not because they can't cure it, but because they don't understand it, Now let's introduce the symptoms of temporomandibular joint disorder syndrome?.
Symptoms of temporomandibular joint disorder syndrome?
First, temporomandibular joint (TMJ) is one of the most active and complex joints in the human body, and it is also the only joint with left-right linkage in the body. It is composed of mandibular condyle, articular surface of temporal bone, articular disc between them, articular capsule around the joint and articular ligament (temporomandibular ligament, sphenoid ligament, styloid ligament) to form disc processus complex, which can complete sliding and rotation by mutual coordination; Its movement form is changeable, and its stress condition is extremely complex. TMJ joint capsule is loose and thin, so TMJ is the only joint in human body that can be dislocated without trauma, and the capsule does not tear when dislocated.
Second, the main causes of TMJDS are trauma, psychological factors, dentition loss, malocclusion, dysplasia and so on. The increase of temporomandibular joint load and the decrease of joint tissue adaptability will lead to the change and destruction of the normal shape of temporomandibular joint, resulting in functional disorder: (1) functional disorder of masticatory muscles: mainly for the uncoordinated function, hyperfunction and spasm of masticatory muscles, which is actually an extra articular disease. The structure and tissue of the joint are normal, with abnormal opening degree, abnormal opening type and muscle pain as the main manifestations（ 2) Joint structural disorders: TMJDS has the highest prevalence. It is a normal structural disorder between the articular disc, condyle and fossa. It is characterized by the bouncing in different periods during the movement of opening. It may be accompanied by different degrees of pain and abnormal opening degree and opening type（ 3) Organic changes of joint: there are organic changes in joint bone, cartilage and disc, and continuous fricative or broken sounds can be heard during joint movement. The common changes of tissue structure are: deformation and displacement of articular disc; Injury and degeneration of articular surface; The injury and inflammatory changes of soft tissue after disc herniation; Synovitis, synovial cyst, ganglion cyst, joint effusion, etc.
Third, a large proportion of TMJDS patients are accompanied by disc lesions. Temporomandibular joint disc is composed of dense fibrocartilage, mainly composed of collagen fibers and other soft tissue components, with a certain degree of toughness. It can not only resist the pressure, but also resist the friction, and can bear the squeezing and rubbing of the articular disc when chewing. TMJ is an important part of TMJ. It plays an important role in the process of joint movement, lubrication, stress transmission and buffering. It also coordinates the morphological relationship between condyle and articular fossa. When the temporomandibular joint in infection, trauma and chewing way is not at the time, or joint dysplasia, can lead to abnormal displacement of the joint disc position or can not reset, joint disc lost the function of regulating intra-articular pressure, resulting in joint function disorder, the corresponding clinical symptoms.
matters needing attention
1. Correct bad living habits: avoid chewing cold and hard food, reduce chewing gum, night molars can wear occlusal pad to sleep（ 2) Eliminate the mental state of mental tension, maintain the mental state of optimism, relaxation and open mind（ 3) Don't form the habit of gritting your teeth when you are in a tight job（ 4) Don't open your mouth in a large range. Pay attention to protect the mandibular joint when yawning（ 5) Pay attention to keep face warm in winter. In daily life, if there are symptoms of temporomandibular joint pain, limited opening, joint bounce and so on, we should go to the oral clinic as soon as possible, and carry out relevant examination to determine the cause. Early disease usually choose conservative treatment, but if the development of irreducible disc displacement, osteoarthropathy, seriously affect the life of people need surgical treatment.
