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.
