Lithium Disilicate
I've got a question/comment about strength.
YZ runs around 1200 Mpa, Empress Esthetic around 140 Mpa, Lithium Disilicate around 400 Mpa.
Now tell me if i'm correct, Porcelain is as only strong as the strength between the porcelain and substructure. Now on YZ, the porcelain on the YZ is only 90 Mpa. Empress Esthetic stays the same 140 Mpa. Lithium Disilicate is also the same at 400 Mpa. Making Lithium Disilicate stronger than anything on the market. Now I know the YZ substructure is stronger, but it's weak between the porcelain and YZ substructure (90 Mpa).
Please tell me your thoughts, because what I've seen from most labs and techs for that matter is that they are seriously confused about this and think Zirconium, YZ, In-Ceram is the strongest thing out there, when technically, they're factually wrong. Unless I'm wrong............maybe?
