Just as Paatero ushered in a new era of den- tal radiology at the end of the 1950s with the development of the ortho - pantomograph and the resulting introduction of panoramic view imaging, 3-D processes will, in turn, replace panoramic view imaging. Although digital volume tomography has to date been mostly used for pre-implanto- logical planning and in recon- structive surgery, now other dental disciplines are begin- ning to appreciate the value of this process. It is in ortho- dontics, endodontics, dental surgery and periodontics that digital volume tomography represents a significant im- provement of the possibilities of imaging processes. Its signif- icance in the current domain, pre-implantological diagnos- tics, can be assessed as even greater. Available digital volume tomographs Digital volume tomographs (DVTs) have been on the mar- ket for a good decade, and the number of suppliers of such devices has increased dramati- cally. When observing the device market, two clear trends are evident: the trend towards an all-in-one device (also called dual use) and the trend towards DVTs of various volumes. All-in-one devices In addition to offering 3-D di- agnostics, the majority of DVTs available on the market also provide the option of produc- ing panoramic view images (real images, not reconstructed from a data record) and some- times even lateral cephalo- gram. These devices thus cover the entire range of dental large- scale diagnostics—in contrast with the first generation, which only offered the DVT option. The DVTs of today’s genera- tion are often similar in design and appearance to traditional DVTs. The position of the patient with these and other frame de- vices is typically standing or sitting, while the once domi- nant supine patient position of the first-generation device is passé, except for that required by one DVT manufacturer.
