摘　　要：下颌骨作为面部的关键承重结构,其生物力学特性对于面部形态的维持以及功能的执行至关重要。要想获取其生物力学特性可以通过试验或数值模拟获得,但由于试验有成本伦理等条件的限制,所以数值模拟的应用更为广泛。数值模拟技术通过构建数学模型和计算机算法模拟复杂的下颌骨力学行为,为理解颌面部功能和疾病状态提供了新的视角和方法。本文综述了数值模拟技术在下颌骨生物力学特性研究中的应用与进展,探讨了数值模拟技术在下颌骨整形手术、下颌骨骨折手术、正颌手术、下颌骨病变治疗和下颌骨缺损重建等多个临床领域的实际应用,并对提高数值模拟技术的精度与效率的未来发展方向进行了讨论。通过构建高精度的三维有限元模型,数值模拟不仅能够预测下颌骨在不同生理和病理条件下的力学响应,还能辅助临床医生设计个性化的手术方案,预测手术结果,优化治疗策略,提高治疗成功率的同时降低后期并发症的发生率。尽管数值模拟技术仍在模型精确度和计算资源上存在一定的局限性,但随着该技术与3DP、AI、3D VSP和3D投影技术等前沿技术的发展与融合,数值模拟技术在下颌骨生物力学特性研究中有望得到进一步发展,为临床治疗提供更科学有效的方案。The mandible,as a critical load-bearing structure of the face,is essential for maintaining facial form and executing functions.Its biomechanical properties can be obtained through experiments or numerical simulations.However,due to the limitations of experiments in terms of cost and ethics,numerical simulation is more widely applied.Numerical simulation technology,which constructs mathematical models and computer algorithms to simulate the complex mechanical behavior of the mandible,provides a new perspective and method for understanding maxillofacial functions and disease states.This article reviews the application and progress of numerical simulation technology in the study of mandibular biomechanical properties,discusses its practical application in various clinical fields such as mandibular plastic surgery,mandibular fracture surgery,orthognathic surgery,treatment of mandibular lesions,and reconstruction of mandibular defects,and explores future development directions for improving the accuracy and efficiency of numerical simulation technology.By constructing high-precision three-dimensional finite element models,numerical simulation can not only predict the mechanical response of the mandible under different physiological and pathological conditions but also assist clinicians in designing personalized surgical plans,predicting surgical outcomes,optimizing treatment strategies,and improving treatment success rates while reducing the incidence of postoperative complications.Although numerical simulation technology still has certain limitations in model accuracy and computational resources,with the development and integration of cutting-edge technologies such as 3D printing,artificial intelligence,three-dimensional virtual surgical planning,and 3D mapping,it is expected to further develop in the study of mandibular biomechanical properties,offering more scientific and effective solutions for clinical treatment.
