The root canal space prepared for a foundation restoration is often elliptic or too large, and an unintentionally prepared undercut is sometimes detected. This article presents a dental laboratory technique to reconstruct an endodontically treated tooth using a pre-impregnated fiber-reinforced composite (FRC) system instead of a conventional fiber post. Particular attention was paid to increase the volume of the fiber in the root canal, and care was taken to achieve adequate primary laboratory polymerization of the matrix monomer. This simple technique is useful in the fabrication of an FRC dowel core with increased fiber content. (J. Oral Sci. 49, 179-182, 2007)
