Adapting fiber-reinforced composite root canal posts for use in noncircular-shaped canals.
Post placement in oval-shaped root canals implies the sacrifice of sound dental tissue to adapt the canal shape to fit the post, which can result in one of several significant complications. A semidirect, single-visit, chairside procedure is proposed, which permits the use of an almost anatomically shaped post, starting from a preformed fiber-reinforced composite root canal post of the largest size commercially available. The utilization of this post capitalizes on the advantages of both the fiber post and the anatomical post in oval- and ribbon-shaped canals to provide restoration of endodontically treated teeth.
