三维有限元分析法因其建模准确、重复性高、应用范围广、高效灵活、直观性强等原因应用于口腔种植学领域,已成为研究口腔种植学口腔生物力学的重要手段。种植修复的机械并发症与种植体结构、种植体植入设计方式、咬合负载等原因相关;近年来,许多学者们使用有限元分析法对种植生物力学研究。本文对近年来三维有限元分析法对口腔种植学的研究进展综述。Three-dimensional finite element analysis has the advantages of accurate modeling, high complex-ity, wide application range, effective and flexible, and strong intuitiveness. It has become an im-portant method for the study of oral biomechanics in the field of oral culture. The mechanical com-plications of implant restoration are related to implant structure, implant design and occlusal load. In recent years, many researchers have used finite element analysis to study the biomechanics of plantation. This paper reviews the research progress of three-dimensional finite element analysis on oral implantology in recent years.
目的:通过对胸腰段骨折的有限元分析,寻求一种适用于胸腰段骨折的安全、可靠的有限元模型。方法:回顾、总结、归纳国内外有关胸腰椎骨折有限元分析的相关文献。结果:由于有限元法能全面地反应脊柱及邻近组织的受力情况,故在研究胸腰段骨折的发病机理、治疗和预后等方面具有较大的优势。能较好地替代传统的生物力学实验,使实验条件的可控更加容易。结论:采用有限元法指导胸腰段脊柱骨折研究是可行的。Objective: Through the thoracic lumbar fracture finite element analysis, to find a safe and reliable finite element model for thoracic lumbar fracture. Methods: To review, summarize, and conclude the domestic and foreign related-literature about thoracolumbar fracture finite element analysis. Results: The finite element method can fully reflect the stress of the spine and adjacent tissues, so it has great advantages in the study of the pathogenesis, treatment and prognosis of thoracolumbar fractures. It can better replace the traditional biomechanical experiment and make the experimental conditions easier to control. Conclusion: It is feasible to use the finite element method to guide the study of thoracolumbar spinal fractures.
目的:探究有限元分析法在运动生物力学中应用的研究热点、前沿与趋势,为未来该领域研究提供参考。方法:使用CiteSpace可视化软件,以2001~2022年间中国知网中240篇中文文献和Web of Science中283篇英文文献为样本,通过关键词聚类分析、作者与所属机构分析、突现词探测等生成知识图谱。结果:近二十年有限元分析法在运动生物力学中的应用研究总体呈上升趋势。美国都柏林大学的Gilchrist教授是发文量最多的学者,前交叉韧带和头部分别是突现时间最长和突现强度最高的关键词。结论:以体育学和生物医学工程为主的交叉学科基础下,膝关节和头部的几何模型重建,足球、羽毛球、冰球等专项动作的仿真分析和损伤力学机制探究是当下研究热点,足-鞋和踝关节的仿真分析是前瞻性研究。未来应加强机构间作者的合作,积极探寻人体内部结构在运动过程中的力学响应和损伤机制。
