An alternative 2-step cementation technique to reduce polymerization shrinkage stress in root canals: a case report.

The functional rehabilitation of teeth with endodontic involvement and substantial loss of coronal structure can be a challenging scenario. The use of fiber-reinforced posts (FRPs) promotes retention and supports the restoration. The main cause of failure associated with the use of FRPs is the debonding of the post, mainly due to polymerization contraction or incorporation of voids in the thick resin cement layer during the cementation protocol.
