A method for taking dental bitewing radiographs of a patient's teeth. A receptor positioning device is provided which includes a receptor holding member and an arm including a biting surface for engaging the patient's teeth. The device includes a collimation plate with a cross-shaped opening for passage of radiation from the x-ray machine. A pair of handles extends away from the plate for positioning the device, with one of the handles being radially aligned and the other of the handles being non-radially aligned. Each handle includes a polymeric grip incorporating an arm holder adjacent a base of the handle and having a rectangular opening for slidably receiving the arm and removably securing the collimation plate to the receptor holding member. One rectangular opening is radially aligned and the other rectangular opening is non-radially aligned. The method then includes aligning an x-ray machine with the collimation plate and passing radiation from the x-ray machine through the opening of the collimation plate to expose the receptor, while the patient's hand grasps the collimation plate handle. |
