MA classifies this as a cartilaginous joint FMA:7495 syndesmosis dentoalveolaris Wikipedia:Gomphosis 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] dento-alveolar syndesmosis UBERON:0001035 MA:0001499 socket peg-and-socket joint calcareous tooth jaw skeleton fibrous joint alveolar ridge
