Abstract
The temporomandibular joint is situated at the base of skull formed by articulation of mandibular fossa of temporal bone and head of condyloid process of mandible. It allows both hinge and gliding movement. As we are aware that due to movements of the temporomandibular joint, it is possible to chew food which provides nutrition to the body, and without which the body cannot function. However, the temporomandibular joint is subjected to various disorders like internal derangement, inflammatory arthritis, arthrosis, and muscular disorders affecting the movement of the joint. Owing to its functional significance, this joint assumes great importance for dental surgeons. The aim of the chapter is to highlight the anatomy and associated disorders of the temporomandibular joint, which will aid clinicians in managing various disorders of the joint.
