The device and the tables for the determination of the angles of inclination of the osseous structures of the cranium from three cephalometric planes: horizontal, median-sagittal, and frontal

摘要

The paper describes the ?Cephalogoniometer?, a device which enables an accurate determination of the horizontal, mediansagittal and frontal planes, and the angles of inclination on the osseous structures of the cranium in relation to the horizontal and median-sagittal planes. For the measurements of the inclinations from the frontal plane, which cannot be made with the above device, the author created the tables which make possible an evaluation of the angle inclinations from the third plane, on the basis of the known values of the angles of inclination of the two first mentioned planes.
