**2.1 Fiber reinforced epoxy resin posts**

Reinforced with black carbon fibers which are later coated with quartz fibers to mask the black color and to improve the easthetics. These posts possesses inherent flexibility that is similar to that of natural teeth [dentine], allowing the post to behave similar to the radicular dentine, which absorbs stresses and prevents root fracture. at the same time these posts causes failure of the cement seal at the margins of the artificial crown, especially when the ferrule is minimum [5].
