SEM photomicrograph of SP110 group showing: (A) Magnification (80x) showed cohesive failure within the hybrid ceramic with fractured lines. (B) Mixed failure mode of type (M2) with hybrid ceramic appeared as if it was dragged from the resin cement. (C), Higher magnifications (600x magnification) showed irregularly distributed resin on the surface. (D) Magnifications (1000x) showed separate clusters of thick layers of the resin cement.
