Despite it being an older, conventional production method, the cast metal post and core is still often considered the best option for the restoration of severely damaged teeth. The direct technique for fabrication of cast post-and-core patterns, however, can pose challenges due to the inefficiencies and guesswork involved in creating an appropriate form and dimension for the core segment. This article presents an enhanced technique for cast post-and-core fabrication in reference to the desired dimensions of the final restoration. As the authors demonstrate, the procedure involves creation of an accurate and passive pattern of each post space. Bis-acrylic composite resin is then injected into a putty impression of the idealized wax-up and seated on the prepared post patterns. A preparation of the abutments is then performed by creating the cores according to the desired dimensions of the final restoration. The major advantages of this technique include a more efficient workflow and a reduction in the number of adjustments needed after insertion.
