Pleurodont is a form of tooth implantation common in
reptiles of the order
Squamata, as well as in at least one
temnospondyl. The labial (cheek) side of pleurodont teeth are fused (
ankylosed) to the inner surface of the
jaw bones which host them. The lingual (tongue) side of pleurodont teeth are not attached to bone, and instead are typically held in place by connective ligaments. This contrasts with
thecodont
Thecodontia (meaning 'socket-teeth'), now considered an obsolete taxonomic grouping, was formerly used to describe a diverse "order" of early archosaurian reptiles that first appeared in the latest Permian period and flourished until the end of t ...
implantation, in which the teeth are set in sockets and surrounded by bone on all sides.
