摘　　要：背景:根管治疗后牙髓根尖周病变患牙往往因失去较多健康牙体组织等原因导致抗折强度降低,如何增强牙齿抗折强度一直是临床医生密切关注的问题。有限元分析能直观地展示不同状态下患牙各个部分的受力情况,对牙体结构和材料力学性能等进行综合分析。目的:综述有限元分析在牙髓根尖周病根管治疗中的应用进展,并对未来的发展趋势进行展望。方法:在PubMed、Web of Science数据库和中国知网、万方数据库、维普数据库、中国生物医学文献服务系统中检索使用有限元法分析牙髓根尖周病根管治疗的相关文献,英文检索词为“FEA,finite element analysis,stress analysis,root canal treatment,pulp opening,root canal preparation,root canal filling,restoration”,中文检索词为“有限元分析,应力分析,牙髓根尖周病,根管治疗,开髓,根管预备,根管充填,修复”,最终纳入103篇文献进行综述。结果与结论:有限元分析可以通过构建牙体及周围组织的有限元模型分析牙齿在咀嚼、咬合等过程中的应力分布和变形情况。借助有限元分析,临床研究者能够对牙髓根尖周病根管治疗中不同开髓洞型、根管预备方式、根管充填材料及修复方案等对牙体力学性能的影响进行分析,从而选择出最佳的治疗方案,提高治疗效果和患者预后。有限元分析有助于医生在临床治疗中减少牙体组织的损失,提高治疗效果和患者预后。有限元模型是对实际情况的简化,需结合临床试验进行综合分析。BACKGROUND:Fracture strength of the affected teeth after root canal therapy is often reduced due to the loss of healthy tooth tissues.How to enhance its fracture strength has always been an issue of concern for clinicians.Finite element analysis can visually show the stresses on various parts of the tooth in different states,and provide a comprehensive analysis of the tooth structure and the mechanical properties of materials.OBJECTIVE:To review the progress in the application of finite element analysis in endodontic root canal treatment of endodontic periapical disease and to look forward to the future development trend.METHODS:Literature related to the use of finite element analysis in root canal treatment of endodontic periapical disease was searched from foreign language databases(PubMed and Web of Science)and Chinese language databases(CNKI,WanFang,VIP,and China Biomedical Literature Service System).The search terms in English were“FEA,finite element analysis,stress analysis,root canal treatment,pulp opening,root canal preparation,root canal filling,restoration”and the search terms in Chinese were“finite element analysis,stress analysis,endodontic periapical disease,root canal treatment,pulp opening,root canal preparation,root canal filling,restoration.”Finally,103 articles were included in the review.RESULTS AND CONCLUSION:Finite element analysis can be used to analyze the stress distribution and deformation of the tooth during mastication and occlusion by constructing a finite element model of the tooth and surrounding tissues.With the help of finite element analysis,clinical researchers can analyze the effects of different types of open cavities,root canal preparation methods,root canal filling materials and restorative solutions on the mechanical properties of the tooth body in the root canal treatment of endodontic periapical diseases,so as to select the optimal treatment plan that improves therapeutic outcomes and patient prognosis.Finite element analysis helps clinicians to reduce the loss of
