title: Tracing error with Björk's mandibular structures.
abstract: The tracing errors associated with the structures used in Björk's method of mandibular superimposition are investigated using multiple tracings of fifty lateral cephalometric radiographs. The horizontal error levels were much less than the vertical, midline structures more reliable than bilateral structures, and the lower third molar tooth germ more reliable than the inferior dental canal.
