High Strength Glass Ceramic

Developed to make a difference.

Celtra

The ultra-fine microstructure makes all the difference

The outstanding properties of ZLS (zirconia-reinforced lithium silicate) are a function of its unique microstructure. The presence of 10% zirconia in the glass phase in atomically dissolved form provides high strength and ensures safe and long-lasting restorations. The zirconia is essentially responsible for the nucleation of crystal phase.

The result is a large number of very fine-grained lithium silicate, whose high glass content give the material its excellent light-optical and mechanical properties. Translucency, opalescence, fluorescence and the chameleon effect all benefit, with high edge stability and excellent polishability being an added plus. This ultra fine microstructure allows Celtra to be processed quickly and effciently in a dental laboratory in its crystalline state and in the appropriate tooth shade.

 

The ultra-fine microstructure makes all the difference

Celtra – Zirconia-Reinforced Lithium Silicate

  • Crystallites formed are four to eight times smaller than crystals of conventional lithium disilicates
  • An ultra-fine microstructure that combines high average flexural strength with a high glass content

Lithium Disilicate Ceramic

  • Crystallites embedded in the glass phase are 2000–4000 nm in size and thus significantly larger than Celtra
  • Lower light conductivity and requires a greaterpolishing effort

Meet Bill and Bill, a clinician and a lab owner/technician, as they talk about the benefits of working with Celtra Press.


Celtra Press

The new generation of high strength glass ceramic. Celtra Press is now available for the traditional pressableceramics technology. The system includes ingots, investment, and veneering ceramics.

The benefits of the Celtra® Press system for your dental laboratory:

  • A unique combination of excellent esthetics and high strength > 500 MPa (natural opalescence and translucency, stable margins)
  • Excellent shade fidelity according to the VITA shade system and a surprising chameleon effect (easy shade adaptation to the surrounding teeth)
  • Simple and fast processing (minimal reaction layer, easy to polish, a simplified shade system reduces inventory costs)

Celtra Duo

Celtra Duo (ZLS) is the one and only material block that provides you with an unsurpassed level of freedom, control, and workflow flexibility, resulting in a final restoration in which to have complete confidence with respect to the clinical, functional, and esthetic outcomes. Restorations made with Celtra Duo (ZLS) possess a chameleon effect, enabling them to blend in with surrounding teeth for a natural vitality and lifelike appearance.

  • Unparalleled combination of esthetics and high strength (natural opalescence and translucency, stable margins)
  • Excellent VITA shade matching and surprising chameleon effect (making shade blending easy with adjacent dentition)
  • Dual path processing (MILL and POLISH: 210 MPa or MILL and FIRE 370 MPa)
