1. The temporomandibular joint (TMJ) is the most complicated joint in the body
The temporomandibular (tem-puh-roe-man-DIB-u-lur) joint (TMJ) flexibly connects the lower jaw with the skull and acts like a sliding hinge. The joint consists of a joint socket on the base of the skull (temporal bone) and a joint head on the rear part of the bony lower jaw. In between, there is a complicated fibrous apparatus. The joint is not only complicated, but also manages to achieve top performance every day: the temporomandibular joint is involved in every movement of the mouth, no matter how small (chewing, speaking, laughing, etc.).
2. A TMJ never comes alone
Humans have two temporomandibular joints: one on the right and the other on the left of the skull. The two joints never move independently of each other. With every movement, both joints are stressed simultaneously.
3. The temporomandibular joint is part of a gear
The temporomandibular joint is part of an extensive control circuit made up of nerves, masticatory muscles of the jaw, face and neck muscles. The different areas of the human body are structurally and functionally related. A disorder in the area of the temporomandibular joints can affect the entire musculoskeletal system and dysfunction can lead to pain and discomfort.
4. The TMJ is incredibly flexible
In the true sense of the word, the temporomandibular joint is a hinge joint, which is unique in the human body. The TMJ allows movements in many spatial dimensions. Two fundamentally different movements are possible: the rotational and the sliding movement. In addition, the joint head can emerge from the joint pit (grinding movement), which is also atypical compared to other joints, causing damage when leaving the joint head from the joint pit (strain, sprain).
