Should adhesive debonding be simulated for intra-radicular post stress analyses?

Computational stress analyses of intra-radicular restorations sometimes seem to contradict in vitro and clinical studies. A meta-analysis of in vitro studies evaluating roots restored with metal or fiber posts showed higher fracture strengths with metal posts [1]. However, several clinical systematic reviews that compared intra-radicular restorations showed inconclusive or contradictory results [2 –8]. Some finite element analyses (FEA) showed lower stress values for fiber post restorations while others have suggested similar stress values regardless of post material [9–11].
