TMJ (Temporomandibular Joint) Treatment in Vancouver
The temporomandibular joint is the joint of the jaw and is frequently referred to as TMJ. The name is derived from the two bones which form the joint: the upper temporal bone which is part of the cranium (skull), and the lower jaw bone called the mandible.
TMJ pain is often associated with neck pain and headaches. These problems often result due to the accumulation of stress and tension in the muscles and joints of the spine.
Pain or dysfunction of the temporomandibular joint is commonly referred to as TMJ or TMD. This term is used to refer to a group of problems involving the emporomandibular joint, muscles, tendons, ligaments, blood vessels, and the tissues associated with them.
The unique feature of the temporomandibular joint is an articular disc. The disc is composed of fibrocartilagenous tissue (like the firm and flexible elastic cartilage of the ear) which are positioned between the two bones that form the joint. The temporomandibular joints are one of the only synovial joints in the human body with an articular disc, another being the sternoclavicular joint. The disc divides each joint into two parts. The lower joint compartment formed by the mandible and the articular disc involved in rotational movement (opening and closing). The upper joint compartment formed by the articular disk and the temporal bone is involved in translational movements, sliding the lower jaw forward or side to side. The part of the mandible which mates to the under-surface of the disc is the condyle and the part of the temporal bone which mates to the upper surface of the disk is the glenoid (or mandibular) fossa.
