Cone-beam computed tomography systems (CBCT) are a variation of traditional computed tomography (CT) systems. The CBCT systems used by dental professionals rotate around the patient, capturing data using a cone-shaped X-ray beam. 

This 3-D image is very important to identify vital structures and to make a complex diagnosis.  A CBCT image in combination with a surgical guide is very important in implant surgery to precisely place the implant.
