摘要:

文题释义:

非龋性颈部缺损:指发生在牙颈部的牙釉质和牙骨质处除龋损外的牙体硬组织丧失,形态多样,如浅凹状、圆盘状或楔状缺损,可仅累及牙冠部、牙根表面,或同时累及牙冠和牙根部,累及牙根者往往伴随牙龈退缩。 
三维有限元分析:是分析复杂几何体应力和变形的方法,其原理是将复杂几何体划分为更小、更简单的有限元素,有限元素经过分析后再整合起来得到原几何体的解。
背景:使用纤维桩修复穿髓型非龋性颈部缺损可以改变牙齿的应力分布,显著降低患牙折裂风险,但关于纤维桩改善牙体抗折性的力学机制及穿髓型非龋性颈部缺损的最佳冠部修复方式尚有争论。
目的:综述纤维桩修复穿髓型非龋性颈部缺损后的应力分布模式,在各种受力状态下的抗折能力与断裂模式,以及纤维桩联合不同冠部修复方式的最新研究进展。
方法:应用计算机在PubMed和中国知网数据库中检索2008年9月至2023年9月发表的相关文献,英文检索词为“non-carious cervical lesions,endodontically treated teeth restoration,endodontically treated teeth stress distribution”,中文检索词为“非龋性颈部缺损,根管治疗后牙体修复,根管治疗后牙齿应力分布”,最终纳入56篇文献进行分析。

结果与结论:穿髓型非龋性颈部缺损根管治疗后,应用纤维桩修复可部分改善牙齿颈部应力,同时不会增加牙根纵裂的风险;使应力分布更加均匀,提高牙齿的抗折性。使用纤维桩修复的非龋性颈部缺损牙齿若折断,其断裂模式显示出有利的、可恢复的或可修复的断裂模式。纤维桩联合瓷贴面或贴面式嵌体可能会成为修复穿髓型非龋性颈部缺损的一种较理想微创修复方法。

Abstract: BACKGROUND: The use of fiber post to repair the endodontically treated non-carious cervical lesions teeth can change the stress distribution of the tooth and significantly reduce the risk of fracture of the affected tooth. However, the mechanical mechanism of fiber posts improving tooth fracture resistance and the optimal crown restoration for endodontically treated non-carious cervical lesions teeth are still debated.
OBJECTIVE: To review the stress distribution pattern after restoration of endodontically treated non-carious cervical lesions teeth with fiber posts, the fracture resistance and fracture pattern under various stress states, and the latest research progress on fiber posts combined with different crown restorations. 
METHODS: The computerized search was applied in PubMed and CNKI to retrieve articles published from September 2008 to September 2023 with Chinese and English search terms “non-carious cervical lesions, endodontically treated teeth restoration, endodontically treated teeth stress distribution.” Finally, 56 articles were included for analysis.
RESULTS AND CONCLUSION: The application of fiber post restoration for endodontically treated non-carious cervical lesion teeth can partially improve the cervical stress of the tooth without increasing the risk of vertical root fracture, can lead to a more consistent distribution of stress and enhance the tooth’s ability to withstand fractures. Non-carious cervical lesion teeth with fiber posts that fracture would show favorable, restorable, or repairable fracture patterns. Fiber posts in combination with porcelain veneers or veneer-type inlays may become a more desirable minimally invasive restoration for repairing endodontically treated non-carious cervical lesion teeth.
