Cone Beam 3-D imaging has brought diagnostic and treatment advantages to the orthodontic practice. Evaluation and planning of orthodontic treatment with the aid of these 3D scans is easier and more evident, resulting from the additional information regarding underlying bone structure, as well as the complete dentition and other structures. 3D Cone Beam scans offer lateral and frontal cephs, SMV, orthogonal images and views of the airway, TMJ complex, sinuses, supernumeraries, and impactions. Besides diagnostics, the information can also be used to produce digital study models and CAD/CAM appliance applications. Orthodontist Dr. John Graham noted the ability to manipulate and view 3D images from any angle as “an incredibly powerful tool in treatment planning and evaluation.”
All of these benefits can be obtained while still achieving ALARA principles. This precise imaging method “provides tremendous diagnostic imaging while also maintaining a relatively low ionizing radiation delivery,” says Dr. Graham, adding that the i-CAT’s Quick Scan 4.8 second scan option provides a “wonderful diagnostic fidelity,” that enables him to “provide my patients with a very low radiation dose, probably lower than I was providing them with my traditional pan and cephalometric techniques, while gaining tremendous diagnostic advantages.”
Dr. Graham believes that participating in CE courses on topics such as 3-D imaging can help clinicians maintain high standards of patient care. At the Live 3-D Dentistry Forum, sponsored by the 3D Imaging Institute, on July 29-30 in Anaheim, California, Dr. Graham will explain how CBCT technology can help orthodontists to become better diagnosticians and communicators, while improving patient flow and treatment. He will enlighten attendees on enhanced diagnosis, shortened treatment times and the discovery of pathology that would not have been visible with 2D, as well as the relative radiation risks of 3D vs. 2D imaging and how to share that information with referring doctors and potential patients.
