Intra-Oral and Peri-Stomal Changes Engendered by Evolution of Orthograde Posture and Bipedal Gait

Abstract

Arunachalam Kumar*

This overview attempts to explore the much neglected changes taking place in the head and neck regions of the biped hominid. The changes, especially in the oral and peri-stomal areas have not received the attention they deserve. An attempt is made here to describe and discuss the anatomical adaptations brought about by the shift from a quadruped to biped posture and gait. Metrical and morphological alterations in the functional anatomy of the maxilla, mandible, dentition and the cranial base are focused on. Without these crucial adaptations erect posture and biped gait may well be compromised or rendered ineffective
