Fiber posts simply behave and perform differently.<br />1， In addition to the obvious esthetic advantages， fiber posts cannot corrode， like base metals (including stainless steel) can.<br />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.<br />Material：fiber<br />Package ： 160 * FIBER POST    32* DRILLS
