3D Radiology
What is 3D Dental Radiology and how does it work?
When we talk about 3D dental radiology, we are referring to the use of a new type of tomography technology specifically developed for dentistry – Cone Beam Computed Tomography (CBCT). CBCT is a modern imaging technique used across all fields of dentistry that provides 3D images of the patient's entire dentition, making diagnosis and treatment planning easier and more accurate.
The low radiation exposure for the patient, combined with the high image quality offered by CBCT, makes this dental radiology tool a highly valuable asset in dental medicine. The 3D imaging allows for more precise results and offers many advantages compared to traditional 2D panoramic radiographs.

How does CBCT work?
Unlike 2D radiographs, 3D technology provides a three-dimensional view, which means it allows us to take depth into account.
Instead of capturing a square image in pixels (length x height), 3D radiology captures a cube in voxels (length x height x depth). These differences in image capture and the resulting output offer several diagnostic advantages when compared to traditional 2D imaging.

Advantages and Applications of CBCT
– Image quality and precision:
With a resolution between 0.1–0.2 mm, the image accuracy is extraordinary. This is critically important when planning surgical procedures that require exact measurements and positioning of structures such as the alveolar bone, nerves, and blood vessels.
– Identification and detailed visualization of key anatomical structures: CBCT allows for precise planning by clearly displaying important areas like the inferior alveolar nerve, maxillary sinuses, nasal fossae, and temporomandibular joint (TMJ).
– Detailed view of dental roots and supporting structures: This enables better identification of dental caries, cysts, and root fractures, improving diagnostic capability.
– Low radiation exposure: Thanks to its image intensification technology, CBCT requires a much shorter exposure time compared to conventional CT scans. It also allows the clinician to focus only on the area of interest, minimizing radiation to surrounding tissues.
– Comfort and speed: The examination takes only about 3 minutes, with image processing completed almost immediately. No prior preparation is needed, and the patient remains in a comfortable seated position throughout the scan.
