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

Figure 8

Failure mode type 3 demonstrating cohesive failure within the cement. (a) Top view of the fiber post with the resin cement (1) encircling the whole failed post (2) after bond strength testing. (b) Top view of the simulated acrylic resin canal (3) showing resin cement (4) covering the whole simulated resin canal. (c) Lateral view of inner surface of simulated acrylic resin canal (5). Pictures were taken under stereomicroscope at 35X magnification.
