CBCT is a diagnostic imaging tool used to examine the teeth, jaw, and surrounding structures in three dimensions. It shows all your bones, nerves and soft tissues in high detail. The procedure uses X-rays to generate cross-sectional images of the oral cavity which can be viewed on a computer monitor. CBCT is especially useful for diagnosing diseases or conditions involving structures that are difficult to reach with traditional two-dimensional imaging techniques. It is also helpful in planning certain types of dental procedures such as root canals, implants, or surgeries.
