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] However, this result is not supported when size and phylogeny is taken into account.[4]
