Growth of the jaws and anisochronia of bone growth

Teleradiographic recordings were employed to compare growth of maxillary skeleton and changes in dental systems. Facial growth occurs at a constant rate during the period when growth in stature is firstly slowed, and then accelerates with the approach of puberty. Growth rates of different parts of the skeleton are not parallel and the face is not involved in the prepubertal acceleration in statural growth. In contrast, puberty affects the adaptation of the dental system to its maxillary insertion bases by its action on buccal musculature.
