Intramatrix rotation--the frontal bone.
Intramatrix rotation during growth and development was studied by 2-D cephalometric technique with the use of metallic implants in the frontal bone in five patients at the Centre for Craniofacial Anomalies, Malmö General Hospital. The analysis of the frontal bone in the five patients showed rotations of the corpus inside the periosteal matrix from 1 to 9.5 degrees in the mid-sagittal plane. The essential conclusion of these observations is that an intramatrix rotation takes place during the development of the frontal bone. This observation will stimulate further studies of its nature, amount, and direction.
