Basics of Dental OPG & Its Applications
Over the last three decades, dentistry has seen enormous advancements in all of its branches. As a result of these advancements, more precise diagnostic techniques, particularly imaging approaches, have become necessary.
Advanced imaging techniques such as orthopantomography, cone beam computed tomography, and others have replaced simple intra-oral periapical X-rays in modern dentistry. The transition from analog to digital radiography has simplified and accelerated the procedure while also facilitating image storage, alteration (brightness/contrast, image cropping, etc.), and retrieval.
A few things to know about Dental OPG:
The orthopantomogram (also known as a pantomogram, OPG, or OPT) is a single-image panoramic radiograph of the mandible, maxilla, and teeth. From ear to ear, the Dental OPG reveals flattened 2D pictures covering hard structures. OPG captures several photos from various planes and stitches them together to create a single composite panoramic view.
Dr. Patero and Dr. Numato were the first to introduce the concept of OPG and extraoral film. The Focal Trough or Image layer is the foundation of OPG’s operation. It’s a three-dimensional virtual space in which the structures inside (mostly the Maxilla and Mandible) appear distinct and sharp, while the structures outside appear hazy.
The x-ray beam travels through different areas of the jaws as the tube head spins around the patient, providing several images that are absorbed and displayed as one continuous image on the film (“panoramic view”).
Advantages of OPG
- Broader coverage of the patient’s face bones and teeth, including the TMJ
- Low radiation exposure to the patient
- Patient-friendly
- Can be utilized in patients who have a hard time opening their mouths.
- Requires less time to create the image
- Beneficial for patient education and presentation of cases
Uses of OPG for
- Fractures
- Dislocated jaw
- Infection
- Dentition (teeth)
- Surgical planning
- Impacted wisdom teeth
- Periodontal bone loss
- Finding the source of dental pain
- For assessment of dental implant placement
- Orthodontic assessment
