"The orthopantomogram (also known as an orthopantomograph, pantomogram, OPG or OPT) is a panoramic single image radiograph of the mandible, maxilla and teeth. It is often encountered in dental practice and occasionally in the emergency department, providing a convenient, inexpensive and rapid way to evaluate the gross anatomy of the jaws and related pathology."

"initial and progressive evaluation of orthodontic treatment (note an OPG alone is not usually sufficient for preoperative inspection or prosthesis measurement)"
"During an OPG the patient remains in a stationary position (seated or standing) while both the x-ray source and film rotate in combination around the patient. The x-ray source rotates from one side of the jaw, around the front of the patient, and then to the other side of the jaw. The film rotates opposite to the x-ray source behind the patient. It takes a few seconds during which the patient must remain completely still."
"OPG specific detector"
"Correct positioning is empirical for a sharp, accurate and undistorted image. OPG positioning errors are common affecting 60-96% of radiographs, rendering 5-33% uninterpretable. The most common error is tongue not against the hard palate. For interpretation purposes, it is important to be aware of common errors and how they affect image quality."
