Zirconia: More and More Translucent

Abstract Purpose of Review Yttria-stabilized zirconium dioxide, 3 mol% Y-TZP (zirconia, 3Y-TZP) was introduced as a prosthetic material to provide metal-free, tooth-colored, and durable option for the patients. However, its optical properties are not ideal. This review describes different strategies increase translucency zirconia summarizes current knowledge translucent fixed prosthodontic applications. Recent Findings One most common ways increasing is add cubic phase by Y 2 O content. 4Y 5Y partially stabilized materials seem have better compared 3Y-TZP but with less favorable mechanical properties. Summary Despite attempts develop material, still far from those natural tooth structures. Possible solution achieving more could be utilizing nanocrystalline zirconia. The production yet very technique-sensitive, sintering process needs well controlled. Additional research in this field needed before recommendation clinical use. In future, challenge will balance between improved without sacrificing would apply only subtractive also additively manufactured ceramics.
