According to PubMed, in recent decades, a new array of imaging modalities—such as digital imaging, CT, MRI, and cone-beam CT (CBCT)—has provided remarkable new images that continually enhance the accuracy of diagnostic tasks in the maxillofacial region.

The most recent advancement, CBCT, is rapidly gaining acceptance in dentistry because it provides cross-sectional imaging, often serving as a valuable supplement to intraoral and panoramic radiographs.

“With a CBCT machine, imaging is accomplished by a gantry—supported by a permanent drive stand—that revolves around the patient on a fixed horizontal axis. The amount of information obtained in such examinations is significant. In dentistry, we use it primarily for implants because it helps us determine the precise placement. Essentially, the machine provides a broader, more detailed X-ray, showing the bone, teeth, and surrounding anatomy,” explains Dr. Johana Valdes.

CBCT offers a much more comprehensive view compared to traditional methods. “Typically, dentists use a periapical X-ray, which focuses on a single area. This is considered a 2D imaging technique. The CBCT machine, on the other hand, provides a 3D image, which is a game-changer. The CBCT images offer a complete view of both sides of the jaw, from front to back and side to side. This allows us to assess the entire tooth structure and bone density, making it particularly useful for implant dentistry, oral surgery, and endodontics,” says Dr. Valdes.

Although the CBCT machine is a significant investment, it offers tremendous benefits to patients. “A general dentist without a CBCT machine must refer patients to a radiology center, requiring them to schedule an additional appointment, which can be inconvenient. Having the machine in our office simplifies the process. We can take the 3D X-ray on-site and evaluate it within minutes while the patient waits,” Valdes explains.

The increasing adoption of CBCT in dental offices is expected to improve diagnostic accuracy. Using CBCT as a secondary imaging tool helps optimize the health-to-risk ratio, ensuring better patient outcomes.
