4.3 Positioning
Positioning the Patient
To obtain high-quality intra-oral radiography with maximum details, take extra care in
all steps of the radiography process: positioning the patient and the X-ray imaging
system; exposing the intra-oral sensor.
1. Place a protective lead apron on the patient’s chest.
2. Have the patient sit on the chair with the sagittal plane vertical.
 For radiography of the upper maxillary, the Frankfort Plane must be horizontal.
 For radiography of the lower maxillary, the Occlusal Plane must be horizontal.
3. Place the tube head cone on the area you want to take an image.
For further information about the patient positioning and beam angle for each mode,
refer to the following Positioning Instructions.
