What is a cone beam CT scan (CBCT)?

A cone beam CT scan (CBCT) produces detailed three-dimensional images of the jawbone, sinuses, and surrounding dental structures. Unlike traditional two-dimensional X-rays, which show a flat, compressed view, CBCT captures the full spatial anatomy from multiple angles, creating a volumetric dataset that clinicians can rotate, measure, and analyze on screen.

Implant dentists rely on CBCT scans because they reveal bone density, height, width, and contours in areas where implants will be placed. This precision is critical: the scan shows where nerve canals and sinus cavities are located, allowing the dentist to position an implant in bone that can support it without hitting vital structures. The three-dimensional information also helps determine implant diameter, length, and angulation before any drilling begins, reducing the risk of complications during surgery.

CBCT images are also used to assess existing bone loss, detect pathology, and plan complex cases involving multiple implants. Many implant dentistry specialists in Chicago use CBCT as a standard part of the implant planning process because the cost and radiation exposure are justified by the improvement in treatment outcomes. The technology has become routine in practices that focus on implant placement rather than a specialty tool reserved for difficult cases alone.
