Abstract

Access cavity preparation represents the initial step in root canal treatment. Minimally invasive approaches have gained increasing attention and involve advancements in the traditional access cavity preparation. Simultaneously, the development of three-dimensional finite element analysis (3D-FEA) has provided a theoretical foundation for evaluating the merits and drawbacks of various access cavity preparations. Studies using static loading 3D-FEA have suggested that conservative access cavity preparation reduces the concentration of stress in the cervical region, thereby strengthening fracture resistance. However, the lack of support from clinical data raises concerns about the validity of this suggestion. Conversely, studies involving cyclic loading 3D-FEA and dynamic loading 3D-FEA have challenged the prevailing perspectives by taking into account additional factors such as filling materials, thus providing a more comprehensive understanding of the impact of access cavity preparation on fracture resistance. Existing research lacks a comprehensive comparison of the different 3D-FEA methods, and this review fills this gap by providing a systematic assessment of different 3D-FEA methods and their applications in access cavity preparation.

三维有限元分析检修洞准备对第一磨牙抗折性的影响:范围综述。
入路腔预备是根管治疗的第一步。微创方法日益受到关注,并在传统的通路洞预备中取得了进步。与此同时,三维有限元分析(3D-FEA)的发展为评估各种通路洞预备方法的优缺点提供了理论基础。使用静态加载三维有限元分析的研究表明,保守的入路腔准备可减少颈椎区域的应力集中,从而增强抗骨折能力。然而,由于缺乏临床数据的支持,人们对这一观点的有效性产生了担忧。相反,涉及循环加载 3D-FEA 和动态加载 3D-FEA 的研究通过考虑填充材料等额外因素,对普遍观点提出了挑战,从而更全面地了解了入路腔准备对抗骨折性的影响。现有研究缺乏对不同 3D-FEA 方法的全面比较,本综述通过对不同 3D-FEA 方法及其在通路空腔制备中的应用进行系统评估,填补了这一空白。

期刊介绍: The European Journal of Oral Sciences is an international journal which publishes original research papers within clinical dentistry, on all basic science aspects of structure, chemistry, developmental biology, physiology and pathology of relevant tissues, as well as on microbiology, biomaterials and the behavioural sciences as they relate to dentistry. In general, analytical studies are preferred to descriptive ones. Reviews, Short Communications and Letters to the Editor will also be considered for publication. The journal is published bimonthly.
