Final answer:
A gomphosis is a specialized fibrous joint that anchors the root of a tooth into its bony socket. The connection between the dental material and the tooth is facilitated by the periodontal ligament.
Step-by-step explanation:
A gomphosis is a specialized fibrous joint that anchors the root of a tooth into its bony socket. It is also known as a peg-and-socket joint. The connection between the dental material and the tooth is facilitated by the periodontal ligament which spans between the bony walls of the socket and the root of the tooth. This type of joint is functionally classified as a synarthrosis due to its immobility.
