Effect of Fiber Post-Resin Matrix Composition on Bond Strength of Post-Cement Interface

Figure 7

Failure mode type 2 demonstrating adhesive failure between fiber post and the resin cement. (a) Top view of a section following bond strength testing demonstrating resin cement (1) lining the simulated canal made in the PMMA block (2). (b) A lateral view of segments 1 and 2 of the corresponding failed fiber post (3). (c) A lateral view of the same fiber post (3) with no remnants of cement around the fiber post. Pictures were taken under stereomicroscope at 35X magnifications.
