New Dental Hybrid Material in the CAD/CAM Technology and Its’ Opportunities for New Indications
Back in 1997, a Siemens representative informed that there is a new device in Germany that is able to produce ceramic restorations chairside, without the need of conventional impressions. Without any further information, Jose Umberto and Silvio, his brother, travelled to Switzerland in order to participate in a lesson given by the creator of the technique in the University of Zurich, Prof. Moermann. Since then, they followed the technique. After the release of the CEREC 3D, it can be said with confidence that the technology has become a must-have in every dentistry office. As the technology evolved, VITA ZAHNFABRIK was always innovative with their blocks, the first block, MARKI and right after the MARK II bloc, which is used to these days, has evolved in both strength and aesthetics until the release of TRILUXE and REAL LIFE, which unquestionably meet all of the demands of modern dentistry. VITA will surprise the market with the launch of a brand newhybrid product that will, without doubt, change the course of dentistry. Therefore, do not miss the opportunity of learning more about the advances of this new technology.
The Esthetic Limits of CAD/CAM Restorations
Jose Umberto De Luca started his studies at the University of the State of Rio de Janeiro, obtaining his DDS certificate in 1978, working mainly with gold inlays, onlays and PFM for 18 years. In the year of 1997 he started using CAD/CAM technology as a participant of the course “CAD/CAM technology (Computer aided design – Computer integrated manufactory) in restorative dentistry, the CEREC method” at the Dental School of the University of Zurich, Switzerland. At that time, someone can imagine the difficulties to run the CEREC machine in BRASIL and how the results were coming out of that amazing but really tricky machine. As Dr. De Luca was getting confidence with the system, he started to give lessons and courses on the method and the principles of preparation and materials all over Central – and South America. Even knowing that the adhesive idea was introduced by Buonocore around 1955, at that time the process was still a little bit confusing with Silane, acid etch, moist or dry dentin, etc, but one point was clear: Adhesive dentistry was evolving rapidly. Two main incentives drove this evolution. Adhesive techniques combined with the use of tooth-colored restorative materials where and still are frequently requested by patients. They want us to restore their teeth not only anatomically and functionally, but also aesthetically. Although important improvements in bonding have been made in the last 30 years, note that the requirements of an ideal bonding system are quite similar to those indicated by Buonocore. But what about the materials? Are they following this improvement? Of course they are and if we talk about aesthetics, we have to mention VITA as one of the first whom came out with aesthetic blocks for the CAD/CAM technic. In the meantime a discussion started about the dental laboratories. Would that be the end of the lab work? Would the ceramist lose their artist work because of a computer? One thing has to be clarified, for the anterior region if someone wants to have color details as mamelons, mixed with translucencies effects etc. there is no question that a ceramist will be needed, but the question is: will these effects be visible by the patient? The dentist with a macro camera and a dark background inside the mouth will see it, but what about a social photo, will that photo show all the hard work done by the ceramist? For the anterior region, we can discuss these results but for the posterior region, I can guarantee that all these effects satisfy more the dentist’s ego rather than the patient’s expectations. Come participate and watch what a CAD/CAM restoration without characterization and glaze can do for you and your patient when we discuss time and material consumption.
