[Biomorphosis of the mandible]

Described is the postnatal development of the mandible. Estimated are the changes of the basal-angle, gonion -angle, thickness of mandibulae , the postnatal growth of the corpus and ramus mandibulae, the difference of hight between processus coronoideus in equilibrium with caput mandibulae and the width of processus coronoideus and ramus mandibulae. Included are distances of the foramen mentale and the direction of this short canal, the angle of the chin, the linea obliqua , the antilingula and on the medial side of the mandible, the linea mylohyoidea and sulcus mylohyoideus also position and form of foramen mandibulae including the lingula. Measured is the direction of ramus mandibulae, the largest distance between both rami and the distance between the apex of the coronoid process and the outborder of the caput mandibulae. The results are discussed with thoughts of early researchers and some remarks are made to canalis mandibulae.
