Making an accurate impression of root canals prepared for cast dowel and cores can be impeded by the number of teeth involved and the working time of the impression material. These factors aside, the technique described can be used to obtain a detailed full-arch impression that precisely captures remaining tooth structure and all canal spaces. The two-stage technique involves first fitting tapered plastic sprues and making individual canal impressions. A full-arch pickup impression is then made to capture the individual canals. This simple and easily correctable procedure ensures an accurate master cast on which dowels and cores can be indirectly made.
