PubMed ID (PMID): 19213363Pages 71-77, Language: English, GermanSteinbrenner, H.During the past few years, the innovations and improvements of the Cerec system by Sirona have been mainly marked by progress in the software field (the most recent improvement being the introduction of the biogeneric inlay design function for occlusal surfaces). Now the world leader in dental CAD/CAM system has developed a new and completely redesigned recording unit. I was given the opportunity to test Cerec AC for several weeks. In addition to the new design, the very core of the Cerec AC - the new Bluecam 3D camera - is apt to excite both seasoned Cerec users and newcomers alike.
