[摘要]桩核系统目前已成为一种重要的牙体修复技术，临床上桩核冠多用于修复经过完善根管治疗但无法取得良好固位的牙齿。长期以来，金属桩核在临床上占据了重要的地位，但其弹性模量远高于牙本质，易致严重的根折。由于纤维桩的弹性模量与牙本质相似，可以减少根折，以及断裂后易取出等优点，自20世纪90年代问世以来，便备受临床医生的青睐。本文从预成纤维桩的分类、性能、临床适应证等应用的研究进展方面作一综述。

    [Abstract]Nowadays, post-and-core systems have become an important technology of prosthodontics. Clinically, post-and-core crowns are used to restore teeth which have received perfect root canal treatment, but cannot achieve good retention. In a few decades, metal posts have held an important place in clinical application. But the elastic modulus of metal posts is higher than that of dentin, contributing to severe root fractures. Since the elastic modulus is similar to the dentin, fiber posts can reduce root fractures. They can also be easily taken out after fractures. Owing to these advantages, fiber posts have been accepted by dentists since 90 years of 20 centu-ry. This review aims to introduce advanced studies of prefabricated fiber posts in terms of classification, properties and clinical application. ......
