Anatomical Structures seen on Orthopantomogram
An OPG which stands for ORTHOPANTOGRAM, gives a panoramic view of the mandible and teeth.
It is performed using a technique called “tomography”. The X-ray tube moves around the head, the x-ray film moves in the opposite direction behind your head. This generates an image slice where the mandible and teeth are in focus, and the other structures are blurred.
The anatomy consists of the body, ramus and angle of mandible, coronoid process, mandibular notch, condyle of mandible, alveolar ridge, symphysis menti, maxillary sinuses, nasal fossae and 16 upper and 16 lower teeth, as shown in the image below.
