gomphosis

A tooth sits in a specialized socket called gomphosis.

A joint that connects the roots of the teeth and the alveolus is called gomphosis (plural gomphoses).

The motion of a gomphosis is minimal, though considerable movement can be achieved over time-the basis of using braces to realign teeth.

The gomphosis is the only joint-type in which a bone does not join another bone, as teeth are not technically bone.

Dento-alveolar syndesmosis (gomphosis)

In modern, more anatomical, joint classification, the gomphosis is simply considered a fibrous joint because the tissue linking the structures is ligamentous.

The socket of a tooth is often referred to as a gomphosis (type of a joint in which a conical peg fits into a socket).

A gomphosis is a specialized fibrous joint in which a conical process or peg of one bone fits into a hole or socket in another bone.

Weiss' theory states that there is a fibro-osseous ligament formed between the implant and the bone and this ligament can be considered as the equivalent of the periodontal ligament found in the gomphosis.
