Cone Beam

The cone beam (or CBCT) is a new digital radiography technique that appeared in the late 1990s. As its name suggests, it uses a conical shaped radiation beam. This device has the advantage of being more precise than the dental panoramic by offering a resolution similar or even superior to that of the scanner, with the addition of the possibility of a digital reconstruction in 3D. Another advantage is that the cone beam provides more detailed information on small bone structures that are difficult to visualize on a scanner. And unlike this, it allows the entire volume to be radiographed to be swept in a single pass, while also being less irradiating. It also offers the possibility of localizing the examination field on the area to be studied (a few teeth, a jaw), which avoids unnecessary irradiation of other parts of the skull.
