In the past, we didn't have many choices when it came to CAD CAM blocks. But today we do. In this episode, we'll be talking to a dentist who is well aware that Zr wins the strength contest but he has plenty of reasons to stay the course with LiSi. He specifically prefers a specific Lithium Disilicate bloc that saves him the step of firing after chairside milling. To tell us all about it is Dr. Yao-Lin Tang, who has over twenty years of practical knowledge in cosmetic and general dentistry. He is a CEREC user since 2005, a certified CEREC trainer, and a Visiting Faculty at CDOCS.com.
