Dental cone beam imaging continues to change the ways dentists can diagnose, educate and plan treatment for patients. These powerful digital imaging systems are capable of capturing highly detailed 3D x-rays and the applications have moved way beyond planning implant treatments. Cone beam imaging can be a key tool in everything from orthodontics to endodontics, CAD/CAM dentistry, oral surgery and more. But while the information these systems capture is a powerful tool, the radiation they use to create 3D images should be minimized according to the ALARA principle. One of the most effective ways to do this is to limit the exposure by limiting the cone beam system's field of view to only capture the specific area being evaluated or treated. This can mean imaging as small an area as a single tooth for endodontic cases, or the entire head for orthognathic cases. Some cone beam systems feature fields of view targeted towards one or two specific types of treatment, while others feature a wide range of fields of view to handle a wide range of clinical situations. Here are some of the dental cone beam systems with the ability to capture small, medium, and large fields of view.
