Panoramic picture of the teeth: how to do, and for what?

Panoramic picture of the teeth can be considered a «gold standard» in dentistry. Without high-quality x-ray examination of many types of dental treatment are not worth starting.

On film or digital media displays all the dental system: from the nasal bone and the maxillary sinuses to the chin, from one temporomandibular joint to the other one.

Why you need a orthopantomogram?

Orthopantomogram (OPG) is displayed on film or paper at the same time in both jaws with the surrounding soft tissue and bone structure. Qualitatively made a panoramic image gives complete information to the dentist about the state of dentoalveolar apparatus.

In the oral cavity is visually determined by no more than 50% of the tissues. What is deep and hidden from professional view of the doctor, perfectly displayed on orthopantomographic x-ray, without a clear display, it is impossible to make an accurate diagnosis. Finished picture can be printed on paper or x-ray film, and can be viewed from a computer screen.

In the analysis of panoramic x-ray are determined by:

  • hidden carious cavity on contact surfaces of teeth;
  • carious lesions of the root;
  • the presence of cysts, granulomas and other oculocardiac changes;
  • the status of the interdental partitions and periodontal tissues;
  • the stage of teething children;
  • the presence of impacted teeth;
  • tumors of the jaw bones;
  • as the maxillary sinuses.

Modern varieties OPG should include 3d imaging. A three-dimensional image gives a more accurate representation of the condition of the teeth and surrounding tissues, allows to look into the jaws of the patient in real time. On the computer monitor the image is rotated to the desired projection to do a virtual tissue sections and layers to explore a specific area.

Orthopantomogram necessary in all types of dental care. The procedure does not cause pain, takes a little time, virtually no contraindications.

  • to assess the quality of endodontic treatment and the condition of the roots of the teeth before the prosthesis;
  • if you select orthodontic structures (braces) to align teeth and changes in the distal or mesial malocclusion. Before installing, multibinding system will determine the required number of places;
  • during surgery;
  • during this surgery, complicated tooth extraction, dentist, surgeon it is important to see not only the problem tooth, but also the surrounding tissue;

  • high image quality;
  • in the analysis of the digital image on the monitor has the ability to bring the desired area for more detailed examination;
  • thanks to the Internet, the panorama can instantly send to any place. This is useful when the attending physician is in another clinic or city;

► How often can you do?

To conduct the panoramic x-rays as often as is necessary to establish an accurate diagnosis and effective treatment.
