Do you suffer from toothaches, Temporomandibular Joint (TMJ) pain, and other jaw problems? Our National Dental Care practices use a screening x-ray called an orthopantomograph (OPG) to quickly identify the source of these issues and help treat them as quickly as possible.
An orthopantomograph is a panoramic x-ray used in our dental practices to capture a wide view of the upper and lower jaw. They provide a single, two-dimensional, half-circle view of the lower face, teeth, and jaws from ear to ear.
An OPG takes multiple, composite panoramic images, which our dentists use to identify dental and structural problems in the maxilla, mandible, and teeth. This screening is a convenient, affordable, and rapid way to evaluate the anatomy of your jaw. These x-rays display all teeth in the upper and lower jaw, and also the position and growth of teeth, including those that haven't surfaced or erupted. These scans can also show the sinuses located above the upper molars.
OPG screenings differ from the traditional, close up x-rays that dentists take of individual teeth. An OPG can reveal problems with the jawbone and the TMJ which connects the jawbone to the head.
OPGs are used to plan orthodontic treatments, implant surgeries, wisdom teeth removal, and root canals. A dentist may request an OPG to help evaluate the following situations:
Some reasons why our dentists prefer to use an OPG include the following:
Similarly to other x-ray imaging, you will be required to remove any jewellery, eyeglasses, hairpins, and other metal objects you are wearing. These items will interfere with the x-ray screening and cause distortions on the final image.
Our technician will have you sit or stand next to the OPG machine where you will need to rest your face on a small shelf, then bite down on a plastic spatula, so that a photograph your teeth can be taken.
An x-ray tube and sensor plate will rotate briefly around your head, taking two-dimensional images of your teeth, bones, and jaw joints. Although the OPG only captures limited parts of your anatomy at any one time, it will give a composite picture of your teeth and maxilla facial structure. In most cases, the entire OPG process will take less than one minute.
