How should the technique be modified to take a panoramic radiograph on an edentulous patient?

In taking a panoramic radiograph, positioning is crucial for accurately capturing the anatomy of the patient. A fundamental aspect of obtaining a clear and useful radiograph in an edentulous patient is ensuring that the positioning light is aimed correctly. By aiming the canine positioning light at the corner of the patient's mouth, you are aligning the radiographic equipment with the anticipated area of interest, which is especially important in edentulous patients, as they may have anatomical variations due to the lack of teeth. This alignment helps ensure that the resultant image will have the necessary landmarks well-visualized, aiding in effective diagnosis and treatment planning.

This technique adjustment is particularly significant because edentulous patients can have altered bone contours and dental arches, making the typical landmarks less reliable. Proper positioning allows for better representation of both hard and soft tissues, which is vital for providing comprehensive dental care.
