BACK TO BASICS: THE CHANGING FACE OF EQUINE DENTAL CARE
Fig. 3. Positioning for the DV view. Line up the central beam perpendicular to the dorsal plane (which is nearly parallel to the palate and the sensor) by looking directly over the x-ray generator.
Fig. 4. Positioning for the DV with offset mandibles. One assistant is using gauze bandage material to pull the maxilla to the horse’s left, whereas the other pulls the mandibles to the right. A commercially available device (right) designed to offset the mandibles.
Fig. 5. Straight DV view (left) and the DV with the mandibles offset to the horse’s left (right). Note that the central beam is aligned down the long axis of the right maxillary 3rd premolar (107) in the image on the left, with poor detail of the maxillary molars. In the image on the right, the central beam is directly down the long axis of the right maxillary 3rd and 4th cheek teeth (108, 109), with poor detail of the 2nd premolar (106) and the 3rd molar (111).
