摘要

Direct intraoral fabrication of multiple post-coping restorations for an overdenture in the same arch can be a time-consuming chairside clinical procedure. In addition, accurate intraoral fabrication of resin patterns with intracrevicular margins is not always possible as a result of limited access. This article presents a direct-indirect method that uses an elastic cast for fabrication of multiple post-coping restorations with intracrevicular margins. Custom post patterns are fabricated directly in the root canal with autopolymerizing resin (Duralay). An impression is made of the remaining tooth structure, which also includes the post patterns, and a flexible cast is poured chairside. The cast is available within 6 to 8 minutes of impression making and can be trimmed similar to a stone die. The procedure also provides flexibility that allows separation of the cast from the impression without fracture of the custom post pattern or cast. The fabrication of the post-coping restoration can be completed in the laboratory, or if necessary, completed chairside and verified intraorally, before dismissing the patient.
