Abstract
Endodontically treated teeth may require custom cast post and core foundations fabricated using direct or indirect methods.1–5 Direct fabrication involves gutta-percha removal to the desired post length and precise adaptation of autopolymerizing resin to the canal space (Figure, A). Poor lubrication or the presence of undercuts in the root may result in a fracture of the resin post pattern within the canal space (Figure, B). Removal of this unwanted resin is difficult and presents a clinical challenge.
