<p>A receptor positioning device for taking dental bitewing radiographs of teeth inside a patient's mouth includes a rigid fixed structure having a collimation plate (12) defining a substantially rectangular opening (16). A receptor holding member (30) is adapted to receive a receptor, and an elongated arm (20) is adapted to receive and couple to the collimation plate. The elongated arm extends towards and couples with a rear portion of the receptor holding member, opposite the collimation plate, such that an unobstructed path is defined between the rectangular opening of the collimation plate and the receptor. A biting surface (22) is fixedly attached to a distal end of the elongated arm and adjacent to the receptor holding member such that the receptor is positioned behind the teeth on which the radiographs are being taken while the biting surface is gripped by the teeth on the opposite side of the patient's mouth.</p> |
