Abstract: A dental X-ray positioning device includes a bite block for gripping receptor. The bit block may be adjusted to accept receptors of various dimensions. The bite block provides the clinician with greater freedom to accurately position the receptor relative to the X-ray source without having to utilize many different devices. The system thereby improves efficiency during X-ray exams and it also guarantees parallel placement of the receptor relative to the X-ray source and to the dentition being examined. The system also incorporates two soft “jaws” that during use prevent the receptor from drooping or failing to remain in parallel position relative to the bite block, the X-ray source, and/or the dentition.
