Pleurodontis a form of tooth implantation common inreptilesof the orderSquamata,as well as in at least onetemnospondyl.[1]The vestibular (outer) side of pleurodont teeth are fused (ankylosed) to the inner surface of thejaw boneswhich 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 withthecodontimplantation, in which the teeth are set in sockets and surrounded by bone on all sides.[2][3][4]
