ConeBeamComputertomographie

Cone beam computed tomography, often abbreviated as CBCT, is a form of X-ray imaging technology used to generate three-dimensional (3D) images of the teeth, jaws, and temporomandibular joints. Unlike conventional medical CT scans that use a fan-shaped X-ray beam, CBCT employs a cone-shaped X-ray beam that rotates around the patient, capturing a larger volume of data with each rotation. This data is then processed by specialized software to reconstruct a 3D model of the scanned area.

The primary advantage of CBCT is its ability to provide detailed anatomical information in all three dimensions. This allows for a more comprehensive understanding of complex structures and their relationships, which is particularly useful in dentistry and maxillofacial surgery. Applications include dental implant planning, orthodontic evaluations, wisdom tooth removal, and the diagnosis of various pathologies.

CBCT scans typically involve a lower radiation dose compared to traditional medical CT scans, though this can vary depending on the specific machine and scan protocol used. The scanning process is relatively quick, usually taking only a few seconds. The resulting images can be manipulated on a computer, allowing clinicians to view the anatomy from different angles, measure distances, and plan treatments with greater precision. This technology has significantly advanced diagnostic capabilities in fields requiring detailed visualization of bone and soft tissue structures.
