The method CBCT (Cone Beam Computed Tomography), has revolutionized dental and maxillo facial radiological diagnosis by making 3D reconstructions of the anatomical structures examined available. The Cone Beam 3D is a radiological technique of CT scan used to capture data and images of a specific volume of the maxillo facial. Thanks to a specific and powerful developing software, this technique provides diagnostic images on the three planes of space by exposing the patient to relatively low radiation doses. This technology is considered to be “Gold Standard” by implantologists, orthodontists, periodontists and maxillofacial surgeons in patient care. The CB3D is the latest generation of equipment for radiological imaging in dentistry and combines the features of other techniques, now well established as the Orthopantomography (Overview) and x-rays of the skull in lateral-lateral and posterior-anterior, to use cephalometric , representations that are directly achievable with the application software. Oral Surgery has proved to be invaluable in the planning of avulsion of teeth both in adults and in children. In oncology it allows you to define the extension of processes of expansion and impairments anatomically vital. Implantology 3D images emphasize the density of cortical bone, the cancellous bone, the positioning of the inferior alveolar nerve and mental foramen. These images influence the choice of the type of implant to be used, its positioning and width, and the considerations of the speed of the osseointegration process Orthodontics Conversely equipment for Orthopantomography and Teleradiography that provide 2D data can not be further explored, the cone beam radiology, based on three-dimensional acquisitions, produces different types of images that are more precise than those produced by the 2D X-ray or a traditional CT scan. Consequently, the cephalometric tracing may be generated confidently. ATM Cone Beam equipment leads to a new qualitative and quantitative representation of the temporomandibular joint. Sagittal and coronal provide a good representation of the joint space and allow the identification of possible diseases. Endodontics-Perio These fields of application require images with extremely high quality, to define the structure of the tooth, to determine the exact pathology and accurately plan an effective treatment. Only a thorough examination of the area of interest will make the dentist aware of the less invasive and more suitable action to be taken. ENT Cone Beam CT is the highest quality regarding examinations ENT. In fact it is possible to clearly see all airways, ear structures, the ATM and sinuses. Most of the tests carried out using the conventional CT can be realized, with better results, even with the Cone Beam highlighting a greater number of details and decreasing the patient's exposure to X-rays.
