To perform comparative finite element analysis (FEA)for 2.0 mm standard miniplate and 1.5 mm microplate in isolated symphyseal mandibular fractures.
Two FE models of mandible were developed and symphyseal fracture was created in both of them. Each fractured model was reduced and fixed using two mini plates and two microplates, respectively according Champ's principle. Stresses thus developed in the plates after application of masticatory load were observed in the models.
Results of the study indicated there was no significant difference in the stresses developed in either of the bone plating system.
1.5 mm Microplates can be used in place of 2.0 mm miniplates in isolated symphyseal fractures of the mandible.
对孤立性下颌骨联合部骨折采用2.0毫米标准微型钢板和1.5毫米微型钢板进行对比有限元分析。
建立两个下颌骨有限元模型,并在两者中制造联合部骨折。根据尚普原理,分别使用两块微型钢板和两块微型接骨板对每个骨折模型进行复位和固定。在模型中观察施加咀嚼负荷后钢板中产生的应力。
研究结果表明,两种接骨板系统中产生的应力没有显著差异。
在孤立性下颌骨联合部骨折中,1.5毫米微型接骨板可替代2.0毫米微型钢板使用。
