摘要：

目的：探讨预成金属桩、铸造金属桩、陶瓷桩、纤维桩等材料在临床应用中的优缺点,评价纤维桩的机械性能、美学性能以及材料的生物相容性。
方法：以“纤维桩，桩核修复，口腔材料，粘固材料，黏结剂”为中文关键词；以“fiber post, post-core restoration, dental materials, cement material, binder”为英文关键词，采用计算机检索1990-01/2008-10相关文章。纳入与纤维桩在残根残冠修复中的应用研究相关文章；排除重复研究或Meta分析类文章。以24篇文献为主重点讨论了纤维桩的机械性能、生物相容性以及纤维桩的黏接固位。组织工程血管材料的种类及其性能。
结果：鉴于传统的金属桩容易导致根折的发生、易腐蚀、同时存在美学性能和生物相容性的问题，纤维桩与传统的金属桩相比,纤维桩的强度、硬度、美学性能、抗腐蚀、抗疲劳性能以及生物相容性均比较优越。而且，纤维桩可以通过树脂类黏接剂与根管牙本质之间达到很高的黏接强度，这可以延长修复体的使用寿命，并能减少根折的发生，有利于牙齿的保存和失败后的再修复。同时纤维桩质量更轻是金属桩的很好替代品。而且在修复失败后，纤维桩更易取出，使得再修复容易进行。纤维桩和树脂类核的联合使用，可以使最终的修复体更加接近天然牙的本来结构。                                                                             
结论：纤维桩具有合适的弹性模量，良好的美容修复效果，黏结效果可靠，易鉴别、易去除，修复成功率高，操作简便，是一种新型、理想的美观桩核材料，值得在临床上广泛推广应用。

Abstract:

OBJECTIVE: To investigate advantages and disadvantages of preexisting metal post, casting metal post, ceramic post, and fiber post for clinical application, and to evaluate mechanical function, esthetical performance, and biocompatibility of fiber post.
METHODS: Articles were retrieved with the key words of “fiber post, post-core restoration, dental materials, cement material, binder” in both English and Chinese between January 1990 and October 2008. Inclusion criteria: Articles addressing clinical application of fiber post for repairing residual root and crown were included. Exclusion criteria: Duplicated studies or Meta analysis was excluded. A total of 24 articles were included to investigate mechanical function, biocompatibility, and stickiness and retention of fiber post.
RESULTS: Traditionally, metal post was easily folded and corrosive; in addition, esthetical performance and biocompatibility were still dissolved. Intension, hardness, esthetical performance, corrosion proof, fatigue resistance, and biocompatibility of fiber post were superior to those of traditional metal post. Furthermore, fiber post was able to highly adhere to root canal dentin via resin splicing agent, which could prolong useful life of dental prosthetic restoration, reduce root folded onset, and benefit for dental storage and repairing. Light mass of fiber post was another advantage compared with metal post. If the repair was failure, fiber post was easily taken out and reused. The combination of fiber post and resin nucleus was beneficial for dental prosthetic restoration which was highly closed to original structure of natural teeth.
CONCLUSION: Fiber post was characterized by suitable elastic modulus, great esthetical repairing effect, reliable stickiness, easy identification and removal, high achievement ratio of repairing, and convenient operation; therefore, fiber post was a new and ideal material for clinical application.
