A century later, cone-beam computed tomography (CBCT) radiography was launched in Italy by Attilio Tacconi and Pero Mozzo[ii]. The algorithm for reconstructing a three-dimensional image from a set of two-dimensional projections had been devised by L.A.Feldkamp et al in 1984[iii]. However, CBCT units specifically dedicated to dento-maxillofacial radiology experienced a fifteen-year waiting gap whilst the cost of X-ray tubes, the quality of detector systems and strength of the personal computers developed enough to catch up with the science behind them.
Since that time there has been a global explosion of digital technologies in many spheres of life. We use digital TV, radio and imaging every day, so logically, digital dentistry is fast becoming the norm. More than 50% of dentists using digital technologies report an increase in earnings, and 93% claim they have significantly improved patient experience[iv].
It is only in recent times that CBCT clinical systems affording 3D data have been relatively inexpensive and small enough to be used in dental practices[v]. The advantages of this are infinite, especially within the fields of periodontology, endodontics and implantology. In these disciplines, CBCT 3D scanning is indispensable; the view of the teeth in context, with the surrounding bone and tissue is crucial to release full diagnostic potential and provide greater precision in the selection and placing of implants. Additionally, the cone beam technique uses a single scan capturing the entire area, vastly reducing the amount of exposure time to the patient.
The CBCT digital system allows for clinicians to explain treatment options and provide a virtual presentation of these processes in advance. Implants can be placed on an accurate and high resolution CBCT scans and the digital guides ordered. This guides then help in the precise positioning of the implant. Some practices even have the necessary equipment to take X-rays and mill guides in one sitting.
Carestream Dental, a leader in the arena of digital imaging, offers an exceptionally user-friendly CBCT solution in the CS 9000 3D extraoral imaging system. 3D technology combines panoramic imaging in one, affordable unit. The cone beam limits radiation to a specific oral site, offering the lowest possible radiation dose. Provided with innovative CS 3D imaging software, the unit aids with treatment planning and patient communication using visuals in slice by slice, axial, coronal, cross-sectional and oblique views. What’s more, the integration of the CS 3500 Intraoral Scanner with the Dicom volumes from the CBCT, provides all the information required for guided surgical stents.
