Why choose a fiber post instead of metal or ceramic?
The main reason is mechanical properties. Fiber posts simply behave and perform differently.
1. In addition to the obvious esthetic advantages, fiber postscannot corrode, like base metals (including stainless steel) can.
2. Because the stiffness (Elastic Modulus) of fiber posts is like the tooth structure, they function with the tooth instead of
against it, in helping to prevent fractures and other problems.
