Click here to review the details. Lateral (right or left) projection: The maxillary lateral occlusal projection is used to examine the palatal roots of the molar teeth. For example, the apices of most of the maxillary teeth tilt inward toward the palate. This technique places the front of the film packet toward the PID, prevents the dots from becoming superimposed over the apex of a tooth, and later aids in mounting the processed film. How does the border appear when cone cutting? actual tooth the lengths are not that much different. position using a finger. Turn on the safelight, and turn off the white light. Management of impacted teeth /certified fixed orthodontic courses by Indi Paralleling and bisecting radiographic techniques. The angle formed by the long axis of the teeth and the film/sensor is bisected, and the x-ray beam is directed at a right angle (perpendicular) to the bisecting line. How will the image appear when there is a bent receptor? How does the image appear on a scratched plate? The duplicating machine uses white light to expose the film. Instruct the child to bite gently on the film, retaining the position of the film in an end-to-end bite. Because the film is light sensitive, the duplication process is performed in the darkroom with the safelight. In the paralleling technique, the horizontal angulation of the x-ray beam must be directed through the contacts of the teeth and be as perpendicular (perpendicular means at a right angle with the film/sensor) to the horizontal plane of the film/sensor as possible. www.indiandentalacademy.com 3.
