However, it had a higher than expected fracture rate. This material was said to have a flexural strength of 560 MPa, slightly more than e.max CAD. After all, Dentsply Sirona is also the manufacturer of Celtra DUO, a zirconia-reinforced glass-ceramic. More independent studies are necessary to make any judgment. To put it into perspective, Ivoclar Vivadent’s IPS e.max CAD has a biaxial flexural strength of about 500 MPa.ĭoes stronger mean better, however? It is too soon to tell, and it’s not that simple.
#CEREC TESSERA VS EMAX FULL#
We assume that Dentsply Sirona plans to eventually introduce a full range of VITA shades and is simply testing the waters with the ‘best seller’ range first.Īccording to the manufacturer, the biaxial strength of CEREC Tessera is “more than 700 MPa,”. The material is sold in boxes of 4 blocks, and it is currently available in these shades:Īs you can see, the selection is quite limited. The aesthetics are quite a subjective topic which we will get to later in this article. Simply put, CEREC Tessera claims to be not only aesthetic but also a high-strength ceramic material.
#CEREC TESSERA VS EMAX CRACK#
These crystals increase the density of the material while helping protect against crack propagation.” These blocks also contain virgilite (lithium aluminum silicate), a component of many glass ceramics, which supposedly helps with the aesthetic properties.
According to the official information by Dentsply Sirona, “rod-shaped crystals provide strength in the same manner as rebar embedded in cement. Technically speaking, Tessera is what the company likes to call an 'advanced' lithium disilicate. Only time will tell whether this material is all Dentsply Sirona promises it to be (or if it is another Celtra DUO).īelow are our investigations about its processing and aesthetic properties. We have started using this material in our clinics and so far our experiences have been generally positive. CEREC Tessera promises to be a “trifecta of speed, strength, and esthetics". In March 2021, Dentsply Sirona introduced CEREC Tessera - a lithium disilicate block that seemingly competes with Ivoclar Vivadent’s IPS e.max CAD.
