The Rehabilitation of Severely Damaged Tooth Through Using a Customized Cast Post

Posts have been proposed to reinforce weak teeth that have undergone endodontic treatment, by transferring twisting pressures through the dentin of the tooth roots to the surrounding supporting tissue. The subsequent case studies applied an interdisciplinary approach in utilizing custom cast posts to restore severely damaged treated teeth, resulting in the complete restoration of their appearance and functionality. Ensuring a satisfactory outcome and satisfying the patient required the careful coordination of prosthetic and endodontic treatments, considering the patient's expectations and needs. Traditionally, a durable metal post and core were commonly employed over an extended duration to serve as the foundational restoration for a prosthetic crown. The cast post and core system offer the advantage of having the core seamlessly integrated with the post. The purpose of the post is to maintain the core restoration, which involves rebuilding the damaged coronal structure. This article discusses the use of cast post and core and zirconia restorations for a maxillary left premolar that has been damaged.
