Specifically, the connection is made between the maxillary or mandible to the cementum of the tooth. The motion of a gomphosis is very minimal, though considerable movement can be achieved over time--the basis of using braces to realign teeth. The joint can be considered a synarthrosis or an amphiarthrosis. The gomphosis is the only joint-type in which a bone does not join another bone, as teeth are not technically bone. In modern, more anatomical, joint classification, the gomphosis is simply considered a fibrous joint because the tissue linking the structures is ligamentous[WP]
