Acrodont

Acrodont is a formation of the teeth whereby the teeth are consolidated with the summit of the alveolar ridge of the jaw without sockets.[1] The term also refers to species of reptiles that have such a formation. This formation is common in the order Squamata,[2] with the most other teeth formation in this order being pleurodont, although an extinct snake Dinilysia was thecodont.[3] Acrodontal tooth attachment can also be seen in most rhynchocephalians including Sphenodon, as well as some lizards such as chameleons[4].
