竹纤维素应用于牙科纤维桩的探讨与展望

Discussion and prospect of bamboo cellulose applied to dental fiber post

纤维桩具有美观、优良的生物安全性等优点,被广泛地应用于临床,但也存在局限性和失败病倒,主要表现为纤维桩松动、脱落、折断、核破坏和不可降解等缺点。随着生态可持续发展,植物纤维已被普遍应用,如椰壳、竹纤维等。竹纤维因其具有机械性能好、成本低、可降解、无毒、抗菌、生物相容性好等优点已被学者们密切关注。从现有研究来看,竹纤维具有的机械性能和物理性能基本可满足牙科桩核系统要求,然而这些研究大多都是非医学实验,作为牙科桩核系统的相关研究国内外几乎没有。该文从竹纤维素的机械性能、物理性能、抗菌性、细胞毒性和生物相容性等方面进一步探讨竹纤维素在牙科桩核系统的应用潜力,同时提出限制竹纤维素应用的相关问题与可能改进方法。这将对丰富牙科桩核系统的发展具有比较重要的临床指导意义。

Fiber post has the advantages of beautiful appearance and excellent biosafety,which is widely used in clinical practice.However,it has limitations and failure rate,manifested as shortcomings like fiber post loosening,falling off,breaking,core damage and non-degradability.With the sustainable development of ecology,plant fibers have been widely used,such as coconut shell and bamboo fiber.Bamboo fiber has been paid close attention to by scholars due to its advantages including good mechanical properties,low cost,degradability,non-toxicity,anti-bacteria and good biocompatibility.Based on existing research,the mechanical and physical properties of bamboo fiber basically meet the requirements of dental post and core system.However,such studies are mostly non-medical experiments,and little research at home and abroad focuses on dental post and core system.This paper will further explore the application potential of bamboo fiber in dental post and core system in terms of mechanical and physical properties,anti-bacteria,cytotoxicity and biocompatibility of bamboo fiber.Moreover,related problems limiting application of bamboo fiber and possible improvement methods are proposed.It provides clinical guidance for the development of dental post and core system.
