Abstract
An improved orthodontic face bow which facilitates the making of a secondary orthodontic correction in addition to the primary correction provided by a conventional face bow is disclosed. An armature projects vertically from the arch member of the face bow. The armature extends from a position proximate the exterior surface of the posterior teeth of one level, usually the upper teeth, to a position proximate the exterior surface of the posterior teeth of the other, usually lower level. An engaging surface is provided at the distal end of the armature. A tension member such as a rubber band is used to interconnect the engaging surface of the armature and the anterior teeth of said other level. The tension member provides a rearwardly directed force on the anterior teeth at the level of the engaging means to induce an orthodontic correction on the anterior teeth of said other level.
