Editorial: Dear Reader...
Prof Albert Mehl, Center of Dental Medicine, University of Zurich
Dental CAD/CAM technology has recently undergone enormous development. At the moment, it is the most innovative segment in dentistry and will again be the focal point of this year’s International Dental Show (IDS), where plenty of manufacturers are going to showcase new systems and CAD/CAM solutions. While dental technology was the primary focus in the past, developers are now also looking at the manner in which these technologies can be applied to the dental practice. Digital impressions play a key role in this process. -Manufacturers are currently making large investments in this technology and are thus able to constantly introduce new innovations. In this particular field—handheld systems for -precise 3-D surface measurements—dentistry is the forerunner of all other engineering -sciences, a fact that acknowledges the pioneer achievement of these developments...

Opinion: Safety-first implant therapy
Dr Neal S. Patel & Dr Jay B. Reznick, USA
Cone-beam computerised tomography (CBCT) systems number amongst the most advanced imaging devices that are currently available on the market. The insight into the third dimension simplifies diagnostic procedures, enhances treatment safety and reduces radiation doses for patients. In addition, there are convincing forensic arguments in favour of CBCT. With the aid of 3-D CBCT images, users can -interpret the clinical situation with much greater accuracy. They can evaluate the optimum drilling angles for various perspectives (saggital, coronal, axial) and generate transversal slices and panoramic images. Compared with conventional CTs, CBCT systems are less sensitive to metal artefacts. Thanks to the availability of 3-D imaging, dentists are in a better -position to assess the risks of treating certain cases in-house. In addition, CBCT users can create digital networks with their colleagues and advertise their services to referring dentists...
CEREC: 25 years of proven clinical performance
Dr Dennis J. Fasbinder, USA
Long-term observations indicate that adhesively bonded restorations fabricated using the first versions of the CEREC system (CEREC 1 and 2) achieved higher survival probability rates (according to -Kaplan–Meier) than conventional layered ceramic restorations. CEREC restorations with service times in excess of 20 years still display a degree of clinical excellence, which is normally attributed to metal-based restorations. On the basis of this extensive long-term experience, there are convincing reasons for recommending CEREC-fabricated inlays, onlays, partial crowns, veneers, anterior crowns and pos-terior crowns as an alternative to conventional metal-based restorations...
Case report: Guided implant placement without conventional impressions
Dr Jan-Frederik Güth, Dr Florian Beuer & Prof Daniel Edelhoff, Germany
Today, digital dentistry and CAD/CAM technology are widely used in dentistry, particularly in the field of implantology. While the last decade was entirely dominated by the CAD/CAM-supported fabrication of dental restorations, digital impressions have attracted increasing attention amongst dental surgeons and technicians in the last few years.1, 2
Paperless practice: Six steps to a chartless practice
Dr Lorne Lavine, USA
There is no doubt that the modern dental practice has changed rapidly over the past fifteen years. Dentists have come to realise that with new technology, they can create a practice that is more efficient, costs less to run, and -allows for decentralisation of the front office. Records that were primarily paper- and film-based are being replaced by digital radiography, electronic records, and there is a move towards a paperless, or at the very least, chartless practice. Most offices realise that there will always be paper in a dental practice. Whether it is walkout statements, insurance forms or printed copies of images, paper will forever be part of the dental practice...

For a perfect fit - CAD/CAM bar restoration for the mandible on XiVE implant
Björn Roland & Dr Peter Gehrke, GermanyFor a perfect fit—CAD/CAM bar restoration on XiVE implantsBjörn Roland & Dr Peter Gehrke, Germany
_Conventional or CAD/CAM? Today, dental technicians and implantologists ponder this question more frequently than ever. More and more -often, they tend towards CAD/CAM. Owing to their tension-free fit, CAD/CAM-fabricated solutions are particularly well suited for the restoration of larger jaw sections. Deciding in favour of or against a CAD/CAM restoration should thus always be a team decision. With his expertise and training, the dental technician is able to contribute considerably to an aesthetic and technically perfect result...

From the patient’s perspective: Design, implementation and prostheticso
Dr Götz Grebe & Dr Melanie Grebe, Germany
The cases presented in this article differ in level of difficulty in order to illustrate that navigated implant placement is the procedure of choice for many cases. We also wish to demonstrate that template-guided navigated implant placement is advisable not only in very complex cases. From the very first time the patient presents to the dental -office, the focus of the entire team contributing to the treatment is on thinking and acting from the patient’s perspective and his or her foremost wish to receive a treatment that is safe, not time--consuming, and associated with as little pain as possible.

IPS e.max CAD LT: Computer-aided crown design
Dr Andreas Bindl, Switzerland
CAD/CAM technology allows dental professionals to manufacture solid all-ceramic crowns chairside. A digital image of the preparation is -captured with an intra-oral camera and the crown is designed accordingly. A variety of ceramics are available for the construction of the crown, for -example an aesthetic, easy-to-mill ceramic (IPS Empress CAD, Ivoclar Vivadent). As this leucite glass--ceramic is weaker than zirconium oxide, these crowns must be seated using the adhesive technique (for example with Syntac/Variolink II or Multilink Automix). This makes them strong enough to withstand the masticatory forces in the long term...
Tizian system: No more one-way streets
Thomas Dürr, Germany
Dental technicians, who wish to produce high-class dental restorations and therefore need to select a particular CAD/CAM system, will quickly discover that the choice of materials and production procedures is limited. This is quite disagreeable, -especially because in the majority of cases the cost of such systems is enormous. Presently, the market provides an abundance of mechanical and CAD/CAM systems. To prevent losing track of the choices, one must be aware that CAD/CAM is only profitable if expenditure is low and the system is suitable for a large range of applications. Furthermore, it is important that the added value remain with the laboratory and that the software is easy to use, even for dental technicians with little previous computer knowledge. For these reasons, master dental technician (MDT) Michael Anger uses the open Tizian CAD/CAM system (Schütz Dental), which offers a high degree of personal and creative freedom...
Wieland: ZENOTEC easy - Cost effective and professional
The ZENOTEC easy milling unit offers users the opportunity to enter the world of CAD/CAM professional technology at a low cost level.

R-dental: R-SI-LINE METAL-BITE - Perfect bite registration
For more than a decade, R-dental has -offered METAL-BITE, a universal and the first scanable registration material recommended by Sirona for CEREC applications. METAL-BITE is the standard in dental registration and dental CAD/CAM registration. While it can be used for universal registration, according to German opinion leader Prof Alexander Gutowski, it is suitable for the biteplate of face-bow registration, as well as for dynamic registration (FGP technique)...
ImageWorks: NewTom VGi adds variable FOV feature
ImageWorks has added a new feature to the NewTom VGi, the professional’s choice of Cone Beam 3-D scanners, making it the first 3-D scanner unit to capture both high resolution -images and large volume functionality in a single machine. The new collimation allows the NewTom VGi to obtain resolutions as fine as 0.075 mm voxel, giving the operator the ability to acquire a large 15 cm X 15 cm field of view (FOV) scan when needed. Additionally, it offers four new FOV options, with each of the now seven FOV’s having four separate possible voxel sizes...
White Peaks: White Peaks Dental Systems
White Peaks Dental Systems, a German manufacturer, specialising in the production of dental zirconium blanks, exclusively uses raw -materials from Tosoh (Japan), the world leader in zirconium technology. White Peaks’ blanks are certified to the highest standards (CE, FDA and DIN ISO 13485). The Copran ZR zirconium blanks are compatible with almost all CAD/CAM milling and manual systems.
