摘　　要：种植体的生物力学性能常采用有限元分析方法(FEA)进行评定,种植体受到的力直接传递到骨组织中,而种植体螺纹参数对种植体、皮质骨、松质骨的应力分布具有不同程度的影响。采用UG NX 12.0软件建立24组种植体结构,通过ABAQUS软件分析种植体、皮质骨、松质骨的应力分布,对具有较好生物力学性能的种植体系统用FE-SAFE软件预测其疲劳寿命。分析结果表明:最大应力出现在种植体上,其次是皮质骨,松质骨应力最小;V形螺纹形态下,螺距0.85 mm、螺纹深度0.3 mm组成的种植体(P1-H1)和螺距1.0 mm、螺纹深度0.4 mm组成的种植体(P2-H2)均具有较好的生物力学性能,其疲劳寿命也满足使用要求。研究结果为牙科种植体的结构设计提供了理论参考,在临床植入体实际应用中具有一定的指导价值。The biomechanical properties of implants are often evaluated using the finite element analysis(FEA)method,where the forces on the implant are transmitted directly into the bone tissue,and the implant threading parameters have varying degrees of influence on the stress distribution in the implant,cortical bone,and cancellous bone.UG NX 12.0 software is used to establish 24 groups of implant structure,and the stress distributions of implants,cortical bone,and cancellous bone are analyzed by ABAQUS software,and the fatigue life of implant systems with better biomechanical properties is predicted by FE-SAFE software.The analysis results show that the maximum stress appeared in the implant,followed by the cortical bone,and the cancellous bone have the lowest stress;in the V-shaped thread shape,the implant composed of a pitch of 0.85 mm and a thread depth of 0.3 mm(P1-H1)and the implant composed of a pitch of 1.0 mm and a thread depth of 0.4 mm(P2-H2)had good biomechanical properties,and their fatigue life also met the requirements for use.The results of the study provide a theoretical reference for the structural design of dental implants and have certain guiding value in the actual clinical application of clinical implants.
