Fixed partial denture abutments severely damaged by dental caries or fracture present a challenge to the dentist. The fixed partial denture may need to be removed for endodontic treatment with post and core fabrication. Frequently, the existing fixed partial denture can be recycled as a provisional restoration. Retrofitting the post and core greatly improves the stabilization of the interim as well as the remake of the definitive fixed partial denture. This article describes a chair side procedure for retrofitting posts and cores and, at the same appointment, converting the original fixed partial denture to an effective provisional restoration.
因龋齿或折断而严重受损的固定局部义齿基牙给牙医带来了挑战。可能需要拆除固定局部义齿以进行根管治疗并制作桩核。通常，现有的固定局部义齿可以被改造成临时修复体。对桩核进行改造可大大提高临时修复体以及最终固定局部义齿翻制的稳定性。本文介绍了一种在椅旁对桩核进行改造的方法，并且在同一次就诊时，将原来的固定局部义齿转变为有效的临时修复体。
