Mandibular flexure, characterized by unique biomechanical behaviors such as elastic bending and torsion under functional loading, has emerged as a crucial factor in oral clinical diagnosis and treatment. This paper presents a comprehensive review of the current research status on mandibular flexure, drawing insights from relevant studies retrieved from the PubMed database (www.ncbi.nlm.nih.gov/pubmed), including research conclusions, literature reviews, case reports, and authoritative reference books. This paper thoroughly explores the physiological mechanisms underlying mandibular flexure, discussing different concurrent deformation types and the essential factors influencing this process. Moreover, it explores the profound implications of mandibular flexure on clinical aspects such as bone absorption around dental implants, the precision of prosthesis fabrication, and the selection and design of superstructure materials. Based on the empirical findings, this review provides crucial clinical recommendations. Specifically, it is recommended to exert precise control over the patients mouth opening during impression-taking. Those with a high elastic modulus or bone-tissue-like properties should be prioritized when selecting superstructure materials. Moreover, this review underscores the significance of customizing framework design to accommodate individual variations in facial morphology and occlusal habits. Future research endeavors in this field have the potential to advance clinical diagnosis and treatment approaches, providing opportunities for improvement.
下颌弯曲，其特征在于在功能负荷下具有弹性弯曲和扭转等独特的生物力学行为，已成为口腔临床诊断和治疗中的一个关键因素。本文对下颌弯曲的当前研究现状进行了全面综述，从PubMed数据库（www.ncbi.nlm.nih.gov/pubmed）检索到的相关研究中汲取见解，包括研究结论、文献综述、病例报告和权威参考书。本文深入探讨了下颌弯曲的生理机制，讨论了不同的并发变形类型以及影响这一过程的关键因素。此外，还探讨了下颌弯曲对临床方面的深远影响，如牙种植体周围的骨吸收、假体制作的精度以及上部结构材料的选择和设计。基于实证研究结果，本综述提供了关键的临床建议。具体而言，建议在取印模时精确控制患者的开口度。选择上部结构材料时，应优先考虑具有高弹性模量或类似骨组织特性的材料。此外，本综述强调了定制框架设计以适应个体面部形态和咬合习惯差异的重要性。该领域未来的研究努力有可能推进临床诊断和治疗方法，提供改进的机会。
