个性化下颌体部钛植入支架的生物力学设计

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4ram～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。

The biomechanical design of the individual mandibular titanium framework

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.
