Abstract
Objective: To carry out a current narrative review on the main properties and indications of the dental use of translucent zirconias. Methods: A literature review was performed with articles available in the PUBMED and MEDLINE databases, using as search terms: dental ceramics, zirconia, translucent zirconia, yttrium stabilized zirconia. Results: After reading the articles, it was possible to observe that the tetragonal zirconia stabilized with polycrystalline yttria (Y-TZP) presents an opaque white color, bringing deficiency in aesthetic areas. in dentistry, the main difference found was the increase in the quantity in mol of yttrium oxide, stabilizing this zirconia in the cubic phase (4Y-TZP and 5Y-TZP). This increase in the addition of yttrium causes a decrease in fracture toughness and flexural strength, resulting in a greater translucency of the material. Final Considerations: Translucent zirconias are indicated for aesthetic restorative procedures and contraindicated for posterior restorations, due to their high translucency and low mechanical resistance. However, further clinical studies are needed to determine its correct indication.
