摘要：

背景：在口腔医学中存在着大量的生物力学问题，有限元法是对人体力学行为进行数值模拟的一种有效工具，其在口腔生物力学中的应用越来越广泛。
目的：综述有限元法在解决口腔正畸、口腔修复、口腔种植、口腔颌面外科等领域生物力学问题的研究进展。
方法：以“有限元分析；口腔；生物力学”为中文关键词，以“finite element analysis (FEA)；oral cavity；biomechanics” 为英文关键词。采用计算机检索PubMed数据库、维普数据库1995-01/2011-10有关有限元分析法在口腔生物力学领域应用的文章。
结果与结论：有限元分析可以对口腔结构、形状、载荷和材料力学性能等进行应力分析，可获得模型任何部位的应力值和位移值，并借助计算机从而快速精确地求解，客观、准确、真实地反映应力的分布状况，为研究口腔医学中的有关基础性问题、解决口腔医学中的临床实际问题、发展口腔临床技术手段提供了力学基础，为进一步研究口腔疾病治疗方法提供参考和借鉴。

Abstract:

BACKGROUND: There are a lot of biomechanical problems in stomatology. Finite element method is an effective tool to numerically simulate the mechanical behavior of human; it has more wide application in the dental biomechanics.
OBJECTIVE: To summarize the research progress in the application of finite element method to solve biomechanical problems in orthodontics, prosthodontics, oral implantology, oral and maxillofacial surgery and other fields.
METHODS: A computer-based online search of PubMed and VIP databases was performed for articles related to the application of finite element method in dental biomechanics, published between January 1995 and October 2011, with the key words of “finite element analysis (FEA)”, “oral cavity” and “biomechanics” in English and Chinese.
RESULTS AND CONCLUSION: The stress analysis of oral cavity structure, shape, load and mechanical properties of materials can be performed using finite element analysis; the stress value and displacement value of any part of the model can be gained and the solving process is rapid and accurate with the aid of a computer. The finite element analysis can reflect the stress distribution objectively, accurately and veritably; it provides the mechanical foundation for the research of relevant basic problems in the stomatology, the solution of clinical practical problems in the stomatology and the technical development of dental clinical practice; it provides reference for the further investigation of treatment of oral disease.
