, INTRODUCTION
‘The human mandible has no one design for life. Rather, it adapts and remodels through the
various stages of life, from the slim arbiter of things to come in the infant, through a powerful
dentate machine and even weapon in the full flesh of maturity, to the pencil-thin, porcelain
like problem that we struggle to repair in the adversity of old age’……D.E. Poswillo, 1988
✓ Latin : mandere= chew
✓ Largest bone of the face
✓ Strongest
✓ Horseshoe shaped bone
✓ Only bone of the face that has the ability of movement.
PRENATAL GROWTH OF MANDIBLE
✓ 4th week IUL, developing brain and pericardium → separated by stomodeum.
✓ Buccopharyngeal membrane separates stomodeum from the foregut.
✓ Series of mesodermal thickenings in the wall of the cranial most part of foregut →
PHARYNGEAL/ BRANCHIAL ARCHES
✓ In humans, six pairs of pharyngeal arches form on either side of the pharyngeal foregut.
