Posts are recommended to fortify weak, endodontically treated teeth against intra-oral forces by channeling torquing forces through the radicular dentin to supportive tissue along the roots. The subsequent case studies demonstrate an interdisciplinary approach that employed custom cast posts and complete veneer crowns to repair severely damaged treated teeth, restoring both their appearance and functionality. Coordinating prosthetic and endodontic treatments, while carefully considering the patient's expectations and requirements, played a pivotal role in achieving positive outcomes and ensuring patient satisfaction. Traditionally, the cast metal post and core system has been widely used as the foundational restoration for a prosthetic crown, benefiting from a natural extension of the post within the core. The post's function is to bolster the core restoration, which rebuilds the compromised coronal structure. This article explores the utilization of cast post and core systems alongside porcelain-fused-to-metal restorations for addressing injured maxillary central incisors.
