Panoramic Radiography & Cone Beam CT
Panoramic X-Rays are the most commonly used dental radiographs and provide useful information regarding the dentition, sinuses, temporomandibular joints, impacted teeth, and their relevation to the vital structures such as the inferior alveolar nerve. They are also vital in indicating the available bone height during dental implant planning. Cone Beam CT (CBCT) is a new imaging technology that generates a 3D volume of image data. Using a cone-shaped x-ray beam rather than the linear fan beam of conventional CT’s, a CBCT scanner takes just on revolution around the patient to capture these multiplanar views. With imaging software, the data maybe reconstructed to render 3D views that can be manipulated to show different angle, varying depths and thicknesses, and be selective for certain tissues. The close of radiation needed for a CBCT is much lover than for a conventional CT, and CBCT is more affordable to patients.
