Cone beam computed tomography is a special type of radiograph that is used in dentistry when traditional 2-D x-rays are not sufficient. A CBCT provides the dentist with a 3-D scan of your teeth, soft tissue, bone, and nerves. This becomes especially important in implant diagnosis and treatment planning. The scan allows the dentist to measure with precision the height and width of your jaws to determine the exact size and position of a future implant.
