[Cone Beam CT New tool in diagnostic imaging].

The goal of this article is to show the advantages of the Cone Beam Computerized Tomography (CBCT) compared to classical Computerized Tomography (CT) and to describe several clinical applications of interest with this rather new technology. Invented practically for dentistry, in particular in implantology, the CBCT found major indications in paranasal sinus imaging, in maxillofacial and oral surgery, in periodontology, endodontics and orthodontics. CBCT is very useful to characterize various lesions of jaws with a reserve concerning the study of soft tissues (in that case, an MRI or CT with contrast injection should be preferred). Recently, CBCT is more and more used for temporal bone imaging and studies of small peripheral articulations.
