Handmade and machining in 2013

The availability and sharply increasing use of numerous CAD/ CAM-Systems seems to drastically alter traditional dental restoration fabrication processes. These changes are not limited to the significantly more reliable and precise fabrication process, but also offer a whole range of new materials that cannot be used with traditional fabrication protocols. The excellent esthetic features (i.e., translucency) paired with favorable physical and biological properties have made high-strength ceramic materials such as zirconium-oxide and aluminum-oxide ceramics true alternatives to conventional dental alloys in a variety of clinical indications. For long-term clinical success, however, and to take full advantage of the unique material properties, it is crucial for the laboratory technician and the dentist to understand clinical indications, advantages and limitations, and required clinical and dental laboratory protocol changes for these technologies and materials. The knowledge of material and handling properties as well as combination and application of different ceramic materials is fundamental to the clinical success and longevity. Furthermore, the abilities and limitations of the available CAD/CAM systems must be known and applied. If these guidelines are followed, CAD/ CAM technology and all-ceramic materials are not limited to single crowns and short-span FPDs, but can be applied to construct implant-supported restorations and even full-mouth rehabilitations in complex cases.
This lecture will present and discuss the possibilities and limits of various CAD/CAM-Systems and will detail the capabilities of modern scanners and software and their influence on the daily lab business.
Differences in scanning technology and the various possibilities for the design of tooth- and implant-supported restorations ranging from single-crowns to complex full-mouth-reconstruction frameworks will be outlined and explained. Furthermore, questions about:

  • Where is the line between handmade and machining?
  • Which factors are influencing the acceptance and use of CAD/CAM?
  • Which laboratory procedures are predominately made by hand?
  • Which are the present pros and cons of CAD/CAM?

will be discussed and answered with a variety of clinical cases.
