HEAD POSITIONING FOR THE PANOREX X-RAY MACHINE
Abstract
A device was fabricated to enable a subject's head to be positioned so that successive comparable Panorex X-ray exposures could be made of the oral structures. Evaluations of the device were conducted using a dry skull with and without a bite impression to aid in orientation. The results indicate a lesser variability in the measurements obtained when a bite impression is used, but for practical purposes the results obtained without a bite impression seemed entirely adequate for most projected uses. The coefficient of variability was generally less than 2%. It is concluded that the head positioning device serves its intended purpose to enable the Panorex X-ray exposure to be used as a longitudinal monitoring tool for periodontic, orthodontic, and other dental studies.
