What is CBCT Scanning?
Cone beam CT provides high resolution, volumetric images that provide complete three-dimensional views of maxillofacial anatomy for more thorough analysis of bone structure and tooth orientation.
Cone beam CT delivers lower radiation dose, in-chair patient positioning (as opposed to a tunnel) and quicker scan times when compared to conventional medical CT scan.
Why panoramic X-ray image is not enough?
Panoramic images are magnified and distorted whereas Cone beam images provide undistorted and accurate views of the jaws. As a result the use of panoramic images to perform measurements is unreliable. Another key difference is that CT images provide different views (cross-sectional, axial, coronal, sagittal, etc.) while panoramic x-rays provide only one view with all structures between the x-ray tube and the image detector superimposed on one another. This allows CT images to separate out the various structures.
