Acrodonty (from Greek akros 'highest' [1] + odont- 'tooth') is an anatomical placement of the teeth at the summit of the alveolar ridge of the jaw, without sockets, [2] characteristic of bony fish. Functionally, acrodont tooth implantation may be related to greater bite force. [3] .

Acrodonta are a subclade of iguanian squamates consisting almost entirely of Old World taxa. Extant representation include the families Chamaeleonidae (chameleons) and Agamidae (dragon lizards), with at least over 500 species described. A fossil genus, Gueragama, was found in Brazil making it the only known American representative of the group. [1]

The meaning of ACRODONT is consolidated with the summit of the alveolar ridge without sockets; also : having such teeth.

We suggest that acrodont tooth implantation is yet another skeletal trait associated with bite force. We hypothesize that taxa possessing acrodont dentition also possess a higher bite force, compared to those with pleurodont dentition, relative to body size.

Acrodont teeth are nonrooted and are ankylosed directly to the mandibular and maxillary bones. The fragile nature of the periodontal tissue associated with this type of dentition makes the bones and teeth susceptible to bacterial and fungal invasion.

Acrodonty, where the tooth attaches to the apex of the jawbone, is an unusual form of tooth attachment that has been associated with the highly autapomorphic condition of monophyodonty. Beyond Lepidosauria, very little is known about the relationship between acrodonty and monophyodonty in other amniotes.

Acrodonts are attached on the top surface of the jaw bone as in fish and amphibians. This type of attachment is not very strong and teeth are lost easily and are replaced by new ones.
