Before we get to know the disease, let’s familiarize ourselves with the temporomandibular joint (TMJ), which is inseparable from our daily lives, and is of course also referred to as the “temporal M-joint” or “inferior M-joint”. During the day, this joint moves more than a thousand times a day during chewing, swallowing, speaking, singing and subconscious activities. The pair of temporomandibular M joints, one on each side, always sympathize with each other when they move, and both sides must move together, so if one side moves while the other does not move significantly or does not move, it means that there is a problem. The temporomandibular M joint is a synovial joint, composed of the lower M head of the mandible and the lower M fossa of the temporal bone constitutes the main structure of this joint, the joint surface is covered with fibrocartilage, surrounded by a relatively loose joint capsule, there is a joint disk inside the joint capsule which is also composed of fibrocartilage, and this disk resides between the joint head and the fossa, which is oval, and the upper part is shaped as a saddle, which is concave at the front and convex at the back, and the structure of the joint head and the fossa is perfectly It fits perfectly with the structure of the joint head and fossa, and it plays a role in stabilizing the joints and reducing the pressure on the joints when they move. If the joint disk is tired and on strike, it will give you a warning look in a minute, such as popping or not opening the mouth. Although it is said that restoring the function of the joint disk is not the core of the treatment, but if there is an opportunity to restore the function of the joint disk, how can we miss it? In the joint capsule around some ligament structure, these ligaments can strengthen the joint capsule, think about it, if these ligaments loose, not to mention the joint capsule, even the joint disk will be destabilized, then these disk, capsule want to do their respective essential work naturally difficult. Next, let’s look for this joint in our own body! Find it before we find the ear screen, that is, the ear canal in front of the small bump, put your finger to the ear screen, when we open and close our mouth when the finger will feel a can be moved back and forth bump, this can be moved bump is the condylar eminence, here condylar eminence of the highest is actually the head of the lower jaw, that is to say, feel the condylar eminence is to feel the temporal M joints of the joint head, open and close the mouth is the head of the nest slides! The head slides in the fossa when the mouth is opened and closed, so it is not difficult to find the fossa according to the condyle.
