Abstract

Purpose: To evaluate and compare the efficacy of three osteosynthesis systems in fixation of mandibular angle fractures using Finite Element Analysis.

Materials and methods: In this study, we used a three-dimensional finite element analysis to assess the stress, deformation and strain in three different groups with bite force loads. A three-dimensional finite element model of the mandible with three different plating techniques using modelling software 'Solidworks2018' and was analysed for stress, deformation and strain produced in the bone following biting loads of different magnitude using analysing software 'ANSYS Workbench'.

Results: In this study, we found out that the tensile forces in the matrix miniplate with vertical struts were well distributed in the cortical and cancellous bone on comparison with other two fixation systems in fixation of the mandibular angle fracture and therefore prevents lateral displacement, torsion and bending. The matrix miniplate system revealed less displacement of the fracture segments as compared to the other two plating systems.

Conclusion: The use of matrix miniplate for the treatment of mandibular angle fractures can be considered efficacious. The stress transferred onto the cortical & cancellous bone is least in the matrix plate leading to better stability of the fixation system.

单、双、基质微型钢板在下颌角区骨折中的有限元分析

目的：利用有限元分析评估和比较三种骨合成系统在下颌角骨折固定中的功效：在本研究中，我们使用三维有限元分析评估了三组不同咬合力载荷下的应力、变形和应变。使用建模软件 "Solidworks2018 "建立了三种不同电镀技术的下颌骨三维有限元模型，并使用分析软件 "ANSYS Workbench "分析了不同大小的咬合力载荷在骨骼中产生的应力、变形和应变：在这项研究中，我们发现在固定下颌角骨折时，与其他两种固定系统相比，带有垂直支柱的基质小板的拉力在皮质骨和松质骨中分布良好，因此可以防止侧向位移、扭转和弯曲。与其他两种固定系统相比，基质小钢板系统显示骨折段的移位较少：结论：使用基质微型钢板治疗下颌角骨折是有效的。基质小钢板转移到皮质骨和松质骨上的应力最小，因此固定系统的稳定性更好。
