Challenges in luting fibre posts: Adhesion to the post and to the dentine

The failure pattern of adhesively-luted fibre posts differs from that of metal posts: whereas fibre posts often fail due to debonding, metal posts often cause root fracture [1 –3]. Thus, debonding of adhesively-luted posts has been reported to represent 37% of all failure modes [4,5]. In order to minimize such failures, efficient adhesion to two distinct substrates is required: (1) to the surface of the post and (2) to the dentine of the root canal.
