中文摘要

有限元法作为近年来热门的一种力学分析方法,为研究者们进行生物力学研究开辟了一条更加高效的途径。随着当前材料和技术的不断发展,桩核冠修复已经成为牙体缺损后残根残冠保留与修复的最常见方式之一。但是,对于功能状态下桩核冠应力分布状态的研究结论不尽相同。本文就有限元法在桩核修复所涉及的材料、形态、数目、箍结构、粘接剂等研究领域进行综述,并对影响有限元法结果的相关因素展开讨论。

英文摘要

As a new and non-invasive method for oral biomechanical research, finite element method is an effective tool for dental researchers. As developments in materials and technologies increase, post-and-core restoration has become a common approach for tooth conservation in treating massive dental destruction. However,Results for stress distribution of post-and-core restoration under functional states remain controversial. This article is a brief review of some applications of finite element method in studying post-core-crown restoration, as well as a discussion of the related factors that affect outcomes.
