Superior Aesthetics in Light Transmittance
E-max (Empress) restorations are made from a fully reinforced glass-ceramic (lithium disilicate) material that contains no metal or zirconium substructure. Among dental materials, it most closely resembles natural tooth enamel in terms of light transmission and reflection properties. Thanks to this characteristic, it flawlessly mimics the natural translucency and depth of the tooth.
Why Are E-max Restorations Needed?
-
Anterior Aesthetics: It is the primary choice for single-unit crown (veneer) requirements involving anterior (incisor) teeth, where aesthetic expectations are at the highest level.
-
Production of Laminate Veneers (Porcelain Veneers): It is used in the production of thin porcelain veneers to ensure fracture resistance and excellent color matching.
-
Inlay/Onlay (Porcelain Filling): For extensive tooth structure loss in posterior teeth, E-max porcelain fillings are used instead of standard fillings to provide a more durable and aesthetic tooth restoration.
How does the treatment process proceed?
The tooth or teeth to be treated are prepared in accordance with aesthetic protocols. Three-dimensional (3D) impressions obtained via digital intraoral scanners are transferred to a computer system. The restoration is fabricated from lithium disilicate blocks using specialized CAD/CAM milling units. Subsequently, staining and crystallization firing processes are performed to impart maximum durability and a natural tooth color to the restoration.
Frequently Asked Questions
What is the difference between E-max and Zirconium?
Since E-max is made of glass-ceramic, its light transmission (and thus aesthetics) is superior to that of zirconia. However, zirconia is more durable than E-max in terms of flexural and fracture strength. Therefore, E-max is generally preferred for anterior teeth, while zirconia is preferred for long posterior bridges.
Are E-max veneers durable?
Thanks to its reinforced structure, it possesses long-lasting durability that is fully adequate for single-tooth restorations, anterior bridges, and porcelain fillings.
Conclusion
E-max restorations represent the pinnacle of conservative dentistry practices that prioritize naturalness and aesthetics, combining the material’s translucency with the clinician’s expertise.
