Palatal migration of two mesodens in a prehistoric Tennessee Indian: a case for the blood vessel thrust theory of tooth movement.

The skull of a prehistoric, Middle Mississippian, American Indian shows two mesodens that migrated to the distal margin of the palate. These teeth are positioned in such a way as to avoid the most common intraoral forces affecting tooth movement. The resorption of the palatal bone, distal to the teeth indicates movement caused by forces predicted by the Blood Vessel Thrust Theory.
