The RAPD (Right Angle Positioning Device) is the original color-coded film positioner for intraoral dental x-ray film. It can be used for anterior, posterior and Bitewing exams, and with any brand and size (#3, 2, 1 and 0) of dental film. Its right angle design ensures correct film/cone alignment preventing "cone cutting." Color coded instruments make assembly error proof. Rounded corners and soft, light plastic offers improved patient comfort, and adds flexibility, making film loading quick and easy. RAPDs are autoclavable for over 100 uses. Kit contains: 4 Aiming Rings (2 Anterior/Bitewing, 2 Posterior), 4 Indicator Arms (1 Anterior, 2 Posterior, 1 Bitewing), 16 Bite Blocks (4 Anterior, 8 Posterior, 4 Bitewing)
