Abstract: BACKGROUND: Fiber post is a non-metallic dental restoration material with excellent mechanical properties, biocompatibility, and aesthetic effect. It can be used to restore endodontically treated teeth with a wide range of structural defects.
OBJECTIVE: To review the classification characteristics of fiber posts and their application progress in clinical prosthodontics.
METHODS: The articles about fiber post were searched in CNKI and PubMed databases by computer. The Chinese search terms were “fiber post, classification, dentin ferrule, restoration failure, fiber post removal, CAD/CAM.” The English search terms were “dental fiber post, classification, ferrule, failure of repair, dental fiber post removal, CAD/CAM.” A total of 82 articles were finally included for analysis. 
RESULTS AND CONCLUSION: According to the fiber composition, fiber posts can be divided into carbon fiber posts, glass fiber posts, and quartz fiber posts, and glass fiber posts are the most widely used in clinical practice. The retention force and resistance of fiber posts are closely related to the remaining ferrule, and the number, height, and thickness of the remaining ferrule usually determine the choice of fiber post restoration indications. The bonding process of fiber posts has certain technical requirements, so it is particularly important to follow the standardized operation process. Although fiber posts have good mechanical properties, they may not fit the root canal, become loose, fall off, break or demolition after failed repair during clinical use. It is expected to improve the clinical application effect of fiber posts by customizing and personalizing fiber posts, selecting appropriate surface treatment methods, and exploring new materials and technologies.
