The ProMax 3D is a dental X-ray unit that utilizes three-dimensional imaging technique. This 3D X-ray unit offers panoramic, cephalometric, and 3D imaging as well as complementary and advanced imaging software for all dental radiology. It is easily the most versatile X-ray unit on the market.

In modern dentistry, the need for more advanced imaging techniques is constantly growing. The traditional two-dimensional computed tomography (CT) generates the image of multiple axial slices, whereas the new three-dimensional imaging technique takes the whole volume needed in a single half circle scan. Consequently, the patient is exposed to radiation significantly shorter time.

The three-dimensional tomography is an excellent tool e.g. in implantology, dental and maxillofacial surgery, endodontics, orthodontics, and TMJ analysis. It can also be successfully used in diagnosing ear, maxillary sinus, and respiratory tract diseases.

The imaging technique is based on new CBVT technology (Cone Beam Volumetric Tomography), in which the X-ray beam has a shape of a cone or a pyramid. The operating principle of the CBVT is a lot simpler than the traditional CT’s working method. The technology requires, however, an easily read full-field radiation sensor and high computing capacity for image processing.

The sensor of the Planmeca ProMax 3D unit is a semiconductor-based flat-panel sensor, which – unlike earlier image intensifiers – is insensitive to electric or magnetic field disturbances. Digitally controlled movements ensure that the radiation sensitive sensor produces almost 300 noise-free, undistorted images at pre-programmed angles.

During the scan, each image is made using a short X-ray pulse instead of continuous radiation. The total scanning time is 18 seconds, but the actual exposure time is only 6 seconds. This technique reduces patient radiation dose considerably and forms a stroboscopic X-ray effect which, together with the shortened rotation scan (only 194 degrees), virtually eliminates artifacts, contributing to the outstanding image quality.
