The overall goal of this review was to observe how the material properties of the unfused midpalatal suture have been considered by researchers in finite element analyses of maxillary expansion. Literature from Scopus, PubMed, and Biosis were all considered. Upon completion of the review, it was found that researchers assumed the suture to be vacant, have the same elastic properties as bone, or have elastic properties indicative of soft tissues. By performing a simplified analysis of the maxilla complex during expansion, it is shown that the suture may have a significant influence on treatment outcome. As a result, despite valuable contributions from previous studies, it would be ideal to incorporate a more representative model of the midpalatal suture into finite element simulations.
本综述的总体目标是观察在对上颌骨扩展进行有限元分析时，研究人员是如何考虑未融合的腭中缝材料特性的。我们考虑了来自Scopus、PubMed和Biosis的文献。在综述完成后发现，研究人员假设该缝是中空的，具有与骨相同的弹性特性，或具有指示软组织的弹性特性。通过对上颌复合体在扩展过程中进行简化分析，结果表明该缝可能对治疗结果有重大影响。因此，尽管先前的研究做出了有价值的贡献，但将更具代表性的腭中缝模型纳入有限元模拟中将是理想的做法。
