Corrected master cast procedure for intraoral luted implant frameworks

Large cast frameworks rarely fit multiple implant abutments passively without time-consuming labor-intensive adjustment procedures. Intraoral luting of components has been suggested to achieve a passive fit and eliminate most adjustment procedures. When the intraoral luted framework is returned to the master cast, the implant analogs may not be properly aligned to framework abutments. To complete the restoration, master cast modification or replacement may be required. The procedure described in this article produces a corrected master cast that fits the final framework and preserves the tissue topography of the original master cast.
