When it comes to imaging<\/a> technology for dental patients, there are a number of choices. Both OPG and CBCT offer excellent resolution, clarity, and precision. They also both provide a 3D image that aids in the diagnosis of potential problems. But how do these two technologies differ? Both intraoral photography and cone-beam computed tomography (CBCT) share the same basic principle: imaging many slices of the oral structures to produce a detailed, three-dimensional picture of the patient\u2019s teeth<\/a>, bones, and soft tissues. These diagnostic tools provide different methods for increasing visual detail. For example, when compared to traditional panoramic images or standard intraoral photography, CBCT reveals greater detail about the shape and structure of soft tissue \u2014 including minor irregularities invisible to the human eye. Likewise, OPG offers visibility into smaller crevice angles than standard radiography or contact lens cameras while still producing an image comparable in quality to CBCT.<\/p>\n\n\n\n

OPG or Orthopantomogram<\/h3>\n\n\n\n

OPG is an acronym that stands for \u201coral panoramic.\u201d OPG is a dental x-ray device in which the patient bites down on an acrylic dental bite registration device while a technician takes an image of the teeth with a low-dose x-ray. A OPG is often used to take a full-mouth image of the teeth and supporting structures to identify potential dental problems that could include misaligned teeth, diseased teeth, or missing teeth.<\/p>\n\n\n

OOP images can be stitched together to create a panoramic view of the dental arches. OOP images are usually higher in resolution than CBCT images, making them more suitable for use in diagnosis. A OOP images are also more suitable for diagnosis when the patient is edentulous or does not have any teeth, as CBCT is not suitable for patients with no teeth. OOP devices are often more affordable than CBCT devices and are available in standalone devices that can be used in any dental practice.<\/p>\n\n\n\n

CBCT or Cone-beam computed tomography\u00a0<\/strong><\/h3>\n\n\n\n

CBCT is an acronym that stands for \u201ccomputed tomography.\u201d CBCT is an imaging device that uses x-rays to produce a high-quality, three-dimensional image of the teeth and surrounding tissues. A 3D imaging device may also be called a CT, Cone Beam, or CT Scanner. However, the images taken with a CBCT device are different from those taken with OPG in a number of ways: 3D images produce more detailed visualisations of soft tissue than OPG.<\/p>\n\n\n

CBCT images are stable and can be taken in any position \u2014 unlike the images from OPG, which require the patient to remain in a fixed position. CBCT images do not require tissue retraction. 3D images are more suitable for diagnosis when the patient is edentulous or does not have any teeth. These distinctions between OPG and CBCT allow dentists to select the imaging technology that is most suitable for each individual patient.<\/p>\n\n\n\n

Differences in quality and image resolution<\/h3>\n\n\n\n

Both OPG and CBCT provide excellent image resolution. That said, CBCT images are generally higher in resolution than those taken with OPG. Depending on the type of machine and settings used. 3D images can be up to 10 times higher in resolution than those taken with OPG.<\/p>\n\n\n\n
