All CEREC Tessera restorations can be fixed adhesively (for example with Prime&Bond and Calibra Ceram). The high-strength nature of CEREC Tessera blocks further provide clinical benefits via low minimal wall thickness preparation guidelines and the ability to use conventional cementation. The same microcrystal composition (lithium disilicate and virgilite) of CEREC Tessera blocks that is responsible for the materialвЂ™s high biaxial and flexural strength also contributes to its highly esthetic and dynamic light refraction, transmission, and absorptive properties that mimic the visual vitality of natural dentition.

The dense interwoven crystal composition of CEREC Tessera blocks is key to their high strength and helps suppress the presence of microcracks and subsequent crack propagation. Together, these material constituents combine to create a robustly reinforced, high-density restorative material.

During the firing process, new virgilite crystals are formed and embedded in a zirconia enriched glass matrix. Tessera blocks are composed of a new material containing virgilite. The fast firing time is mainly made possible by the special and new composition of the ceramic made of lithium disilicate and virgilite, a lithium aluminum silicate. Compared to other glass ceramics, this represents a time savings in the entire manufacturing process (grinding and firing). in CEREC Primemill.ДЄdvanced material properties due to optimized microstructureД¬EREC Tessera blocks are an advanced lithium disilicate ceramic for the CEREC workflow that accelerate the entire manufacturing process by shortening the glaze firing time вЂ“ a crown can be fired in the CEREC SpeedFire in just 4 minutes and 30 seconds.

Lithium disilicates play an important role in this group of materials: their results are convincing in all regions of the mouth and they can be used for CAD/CAM-fabricated restorations, i.e. The reason is mainly esthetics вЂ“ patients usually want restorations looking nearly identical to their natural teeth. High-strength glass ceramics are frequently used by dentists when fabricating a restoration.
