The Strength of Resin
A large percent of young dentists believe that resin is a vastly inferior material to some ceramics. An Empress onlay was placed ~2006 as a large DOL (B) restoration. It fractured in 2011 and I placed a direct restoration in tooth #1 but in #2 position. This distal surface of the upper last molar takes the highest forces of any tooth in the mouth. The compressive, flexural and tensile strength of Filtek Supreme Ultra is 3-4 times that of Empress.
