3D X-Ray, technically called CBCT (cone beam computed tomography), is an X-ray imaging technique which uses cone-shaped beams, instead of fan beams in standard CT scanning. During imaging, the CBCT scanner rotates around the fixed head of the patient and acquires about 600 images sequentially.
The dentist can view the CBCT record in different sections and can analyze the area around each tooth in detail.
Its use is versatile. It is advisable to take it whenever 2D images are not sufficient.It is widely used in implant planning, where it provides important information about bone quality, allowing the dentist to prepare for implantation accurately. It is also used for extractions, mainly wisdom teeth, where the position of the roots and adjacent structures is the most variable of all teeth.
In recent years, the use of the CBCT has been considerably increased, in dentistry and endodontics. It provides essential information such as presence of supernumerary root canals, their location or accurate location of a broken endodontic file. It also provides information about the size of inflammatory processes around the teeth.
