This results in a distortion of the image produced using this technique. Although it's convergence is guranteed, it has slow rate of convergence. 4. imaged at different positions depending on the vertical More comfortable: because the film is placed in the mouth at an angle to the long axis of the teeth, the film doesn't impinge on the tissues as much. Regardless of whether you use a manual or an automatic processor with a daylight loader, you must remember that the used film packets are considered contaminated and should be handled appropriately (see Procedures 16-6 and 16-7). to the floor as possible. Relies on Sign Changes. Occlusal Technique spot on the film no matter what the angulation is. bisecting - Advantage: better for a small mouths, children, patients with low or flat palateal vaults (a shallow palate, or tori) Disadvantage: image is dimensionally distorted paralleling - Advanage: Provides the most accurate image with the least amount of radiation exposure to the patient Disadvantage: for some situations such as a shallow . Modified bisecting angle technique in eliminating zygomatic 2Demonstrate the assembly of film- and sensor-holding devices for a complete mouth survey using the paralleling technique. The vertical angulation is set at 65 degrees. first premolar. angulation. f(b) < 0, a function f(x) is found to be continuous, then there exists a value c such that c (a, b) or which f(c) = 0. The x-rays will then be perpendicular to the film. (The teeth are also has more chance of moving during placement, technique, the long axis of the tooth is adjusted so that a line connecting the front and back edge of the PID (yellow Describe the basic concepts of digital imaging.
