Abstract:
1. A receptor positioning device for taking dental bitewing radiographs of a patient's teeth comprising: a receptor holding member adapted to receive a receptor for exposing x-radiation from the x-ray machine; an arm secured to the receptor holding member and including a biting surface for engaging the patient's teeth to secure the device in the patient's mouth; and a collimation plate having a substantially flat surface for aligning with an x-ray machine and made of a material and sized sufficient to attenuate undesired radiation from the patient's mouth, an opening in the plate surface for passage of radiation from the x-ray machine and at least partially corresponding in shape to a receptor in the receptor holding member, and a handle extending away from the plate for positioning the device, the collimation plate including a reinforced arm holder adjacent a base of the handle and having an opening therein for slidably receiving the arm and removably securing the collimation plate to the receptor holding member.
