(Photographs courtesy of ProfKarl-HeinzKunzelmann,Germany) 44 I I meetings _ 9th Ceramics Symposium _The Society for Dental Ceramics (SDC) has followed the development of all-ceramic mate- rials and CAD/CAM technology for the last ten years, reviewing and commenting on the clinical results in the professional community, supported by experience from its own field studies in private practices. During this period, the number of in- serted all-ceramic inlays, onlays, crowns and bridges has increased steadily to over 5.5 million restorationsperyear,thusattaining20%shareof the treatment volume indicated for long-term restorations. At the 9th Ceramics Symposium All-Ceramics at a glance, which was held from 4 to 5 Novem- ber 2009 in Munich in Germany, the moderator Dr Bernd Reiss (Germany) called attention to the results of the Tele-Dialog Survey, which demon- strated that 87 % of the symposium attendees judged the quality of polycrystalline oxide ce- ramic frameworks to be better than or at least equal to that of porcelain-fused-to-gold. Prof Sven Reich (RWTH Aachen University, Germany) supported this assessment and presented a the- matic tour of millable CAD/CAM ceramics. Thanks to a combination of different proper- ties, today there is a suitable ceramic for every indication. Silicate ceramic, known for its trans- lucent chameleon effect, has established itself for inlays, partial crowns, veneers, and crowns, chiefly in the anterior-tooth and premolar re- gions. For extended aesthetic demands, as well as crownsandthree-unitfixeddentalprosthesis(FDP) up to the second premolar, lithium disilicate (LS2) ceramic is available in graded opacities for press and CAD/CAM techniques.
