How CBCT and OPG work
Cone Beam Computed Tomography (CBCT) provides three-dimensional images of the jaws and surrounding bone structures, while an Orthopantomogram (OPG) produces a two-dimensional panoramic view. Choosing between them depends on the clinical question: OPG for an overview, CBCT when depth and cross-sectional detail are needed for diagnosis or planning.
Image quality and the diagnostic usefulness of each scan are shaped by the specific area scanned and correct patient positioning. The clinician decides which modality best answers the clinical question, balancing the broader context an OPG gives against the localized, volumetric detail from a CBCT.
What to expect during scan
When you arrive, a trained technologist will position you for the selected scan; for OPG you will be aligned for a panoramic sweep, and for CBCT you will be placed to capture a focused volume. The procedure is noninvasive; remaining still during image capture is important for a clear result.
Sky Dental Clinic’s Baiyappanahalli location is convenient for commuters using Baiyappanahalli Metro or Old Madras Road, so many patients choose appointments before or after work. Diagnostic imaging demand rises seasonally in January, July and December as treatment planning for restorative, surgical and orthodontic care increases.
How images guide treatment
Orthodontic, surgical and restorative teams use OPG and CBCT images differently: an OPG highlights overall tooth positions and jaw relationships, while a CBCT reveals bone architecture and spatial relationships needed for implant planning, surgical mapping or complex restorative assessment. The choice shapes how treatment options are developed.
After the scan, your dentist interprets the images in the context of your clinical exam and treatment goals. The trade-off between a panoramic overview and targeted 3D detail is decided case by case, ensuring imaging provides the specific information required for safe, informed planning.
