Cone Beam Volumetric Imaging has many advantages over simple panoramic film and digital images, including enabling accurate visualization of head and neck structures and reducing X-ray doses. It has been rapidly adopted and is becoming the “standard of care” for several applications and preferred for others.

Currently, two genres of CAD/CAM systems exist. One is used only in-office, while the other genre is a combination of in-office scanning and image transmission and milling of restorations or pouring of models in the laboratory. All systems start with scanning of the preparation, the method depending on the specific system. CAD/CAM systems have developed considerably, offering accuracy and more options than previously. It can be envisioned that CAD/CAM technology developments will continue to offer dentistry more options for its use, including further CAD/CAM integration of procedures and imaging enhancements.

Cone beam computerized technology (CBCT) offers 3-dimensional visualization and more complex and more accurate imaging compared to analog and digital radiographs. It is an accurate tool for many clinical oral-maxillofacial indications, with lower radiation doses than computerized tomography. The clinician must determine the risk:benefit of imaging for each patient. Clinicians are rapidly realizing the significant advantages of CBCT imaging. Factors to consider in determining whether to purchase a CBCT device or to refer patients to imaging centers include cost, training, time required to generate images and reports, data transmission and storage,and responsibility for interpretation and pathology review.
