Gomphosis is a term used to describe a type of joint in which a conical projection fits into a corresponding socket, allowing for very little movement. Synonyms for gomphosis include a fibrous joint, a peg-and-socket joint and a dentoalveolar socket. These types of joints are found in the teeth and jaw, allowing for the teeth to be anchored securely into the jawbone. Other types of joints, such as those found in the limbs, allow for greater mobility. However, gomphosis plays a crucial role in maintaining the structure and stability of the dental arch, ensuring that teeth are held in place even when subjected to the forces of chewing and speaking.
