OPG, CEPH, 3D X-ray
An Orthopantomogram (OPG) is the complete X-ray image of the mouth, comprised of upper and lower jaw and teeth. The X-rays machine moves around your head to take the image. Pregnant women are not recommended to have an OPG.
OPG is helpful for the following situations:
- To analyze wisdom teeth
- Diagnose the cause of dental pain
- Survey the position of dental implants
- Teeth assessment for orthodontic treatment
Before the procedure, the patient should remove glasses, dentures, hairclips, and all types of jewelry on your head or neck, such as earrings and necklaces.
Orthopantomogram is a safe procedure and involves the following steps:
- Patient is asked to stand in front of the X-ray machine.
- A peg is inserted into a slot of the machine and patient is asked to bite the same.
- Two handles are present below the peg to be held by the patient for balance while taking the image as patient may be asked to lean backward during procedure.
- Patient is fixed in the correct position by using a gentle clamp over his or her head.
- After assuring proper placement, the radiographer starts the machine that moves around your head taking images.
Patients should not move during the procedure, as image may get blurry and the same procedure must be repeated. OPG usually takes about 15-20 minutes for the entire procedure.
