Cone Beam 3D Imaging (also known as CBCT) is a medical imaging technique that provides 3D images rather than the two dimensional images produced by conventional dental radiographs. The added clarity and dimension of the 3D imagery significantly enhances our ability to see in undistorted detail the positioning and spatial relations of the teeth, jaw bone and vital structures such as sinuses and large nerve bundles. CBCT also provides cross section views of teeth not possible using conventional two dimensional x-rays. 3D imagery is an integration of medical CT scan technology with dental panoramic imaging. In CBCT, the machine is sending the X-rays in a divergent cone-shape. A sensor on the opposite side collects the imaging data. Complex computer algorithms then construct a three dimensional image from the data collected. A 3D image, and its corresponding cross sectional slices, can be viewed on a computer monitor.
Dental CBCT, provides a fast, non-invasive way of answering a number of clinical questions. Dental CBCT images provide three-dimensional (3-D) information, rather than the two-dimensional (2-D) information provided by a conventional X-ray image. This may help with the diagnosis, treatment planning and evaluation of certain conditions.
