Effect of Load Cycling on the Fracture Strength/Mode of Teeth Restored with FRC Posts or a FRC Liner and a Resin Composite

Figure 5

Fractured specimens of group B: (a) fracture of buccal, mesial, and distal walls (arrow indicates fiber-reinforced composite); (b) buccal tooth wall fracture with arrow showing the fiber-reinforced material; (c) lateral view of fracture of the buccal tooth wall, with minor secondary cracks (arrow) not extending to the margins; (d) top view of the same specimen (c) showing fracture of the buccal tooth wall extending to restoration margins.
