Zirconia Restorations
Translucent Zirconia
Translucent Zirconia represents the latest generation of zirconia materials, offering significantly improved optical properties compared to traditional zirconia. By incorporating rare earth oxides and multilayer gradients, translucent zirconia achieves a natural tooth―like translucency and depth of color that was previously only possible with glass ceramics.
Available in multilayer disc options that gradient from a more translucent incisal to a more opaque, natural―looking cervical region, translucent zirconia is now a viable option even for anterior restorations where aesthetics are of primary concern.
Questions & Answers
Frequently Asked Questions
Translucent zirconia incorporates a higher proportion of cubic phase zirconia and rare-earth oxide dopants that increase light transmission through the material. This produces a natural tooth-like translucency and depth of colour gradient that was previously only achievable with glass ceramics like e.max — while maintaining significantly higher strength than glass ceramics.
High-translucency zirconia maintains a flexural strength of 700–900 MPa, which is still considerably stronger than lithium disilicate (400 MPa) or feldspathic porcelain. It is appropriate for single crowns in all regions and for short-span posterior bridges, though for heavy bruxers or long-span bridges, standard high-strength zirconia remains the safer choice.
Multilayer zirconia discs are engineered with a gradient from a higher-translucency, slightly lower-strength incisal region to a more opaque, higher-strength cervical region — mimicking the natural optical gradient of a real tooth. Restorations milled from these discs exhibit natural-looking depth of colour without requiring any additional layering.
For many anterior single crown cases, high-translucency multilayer zirconia now rivals e.max in aesthetics while offering greater strength. For ultra-thin veneers (under 0.5 mm) or highly complex shade-matching cases in a smile makeover, pressed e.max may still offer a marginal aesthetic advantage due to the nature of the glass-ceramic material.
