High strength glass-ceramics are used in particular for highly aesthetic restorations. The aesthetic finishing requires special know-how and time. However, in order to cement them in the posterior with a conservative preparation design and, if necessary, conventional manner, the material strength is a particular factor for the safety and durability of these restorations. Seamless workflows in the dental laboratory and the dental practice can offer an additional advantage.
Benefits
The trifecta of speed, strength, and aesthetics in the dental laboratory
CEREC Tessera blocks achieve exceptional three-way performance through a unique chemistry that incorporates two complementary crystal structures within a glassy zirconia matrix. These two crystals work together to create an unprecedented fusion of strength and beauty in one block while significantly improving overall processing time.
Rod-shaped crystals provide strength in the same manner as rebar embedded in cement. These crystals increase the density of the material while helping protect against crack propagation.
Used in glass ceramics, these crystals are unique to CEREC Tessera material. They are activated through the matrix firing process and add strength while contributing to the outstanding aesthetics that give the convincing appearance of natural teeth.
