A clinical case is presented in which a new type of fiber post was used in combination with the proprietary dual-curing resin cement to bond in a wide, nonrounded root canal. The anatomic post was inserted and the relining resin photopolymerized. The anatomic post was then removed and a luting procedure was performed, as for any other translucent post. The clinical procedure was simple, and a superior fit to the root canal walls was achieved, thus reducing the amount of cement needed. The luting procedure described can be proposed as a clinical technique for routine use when the prepared root canal is too wide or not perfectly round.
