ABSTRACT:
A head positioning device for establishing a selected spacial attitude of the head for portraits, cephalometric x-rays and conventional x-rays in orthodontic procedures, which device includes eyeglasses having a lens frame and a pair of temple arms extending rearwardly of the lens frame in conventional fashion, and a pair of level tubes pivotally attached to mounts extending downwardly from the temple arms. The level tubes can be pivotally adjusted with respect to the eyeglasses to facilitate a desired constant head position when a patient is wearing the eyeglasses in order to insure duplicate full face, profile and/or x-ray pictures of the mouth and head which are necessary to insure proper diagnosis, treatment and care. In a preferred embodiment of the invention all components of the head positioning device are shaped from a clear material, and most preferably, from a polycarbonate composition.
