Dental materials are evolving rapidly, and understanding the differences between zirconia, lithium disilicate, and emerging 3D printed materials can help clinicians and technicians make better restorative decisions. Dr. Nate Lawson of the University of Alabama at Birmingham joins Rob Norton to break down the science behind zirconia vs. e.max, including strength, toughness, translucency, bonding, yttria content, and how different zirconia formulations perform in clinical applications. Dr. Lawson explains transformation toughening, the differences between 3Y, 4Y, and 5Y zirconia, multilayer zirconia, fast sintering, and how researchers actually test flexural strength, fracture toughness, fatigue, and restoration performance. The conversation also explores resin based permanent restorations, 3D printed zirconia, ceramic filled crown materials, and why laboratory testing methods and manufacturer claims need to be understood before comparing restorative materials. Looking toward the future, Dr. Lawson shares where he sees 3D printed ceramics heading and how dentists can think about choosing between milling, 3D printing, and traditional laboratory workflows as restorative technology continues to advance.
