摘　　要：目的:对下颌钛植入支架进行生物力学分析,以期提高修复成功率。方法:根据镂孔孔径不同及孔间隔的不同,对下颌钛植入支架进行不同方案镂孔设计,并利用Ansys有限元分析软件对其进行力学分析。结果:对钛植入支架不同镂孔设计方案的力学分析表明,基桩预留孔道之间钛表面连接部分,以及孔道周围应力较集中,建议孔径可采用4mm～6mm,孔之间横向间隔为3mm或以上,纵向间隔为2mm或以上。结论:所设计的下颌钛植入支架完全可满足咀嚼所需的力学承载要求。Objectives： In order to improve the success rate, the biomechanical design of the individual mandibular titanium framework was analysed. Methods： Different hollowed-out designs of the framework （mainly on the diameter of the hollow and the space of the hollows） were analysed through ANSYS. Results： The analysis of the different hollowed-out design of the framework indicated that the concentrate area of stress was between the 2 abutment screw holes. It is suggested that 4-6mm of the diameter of the hollow is suitable,and the horizontal space of the hollow is 3mm at least, while the vertical space is 2mm at least. Conclusion： This research shows that this individual mandibular titanium framework design is feasible.
