摘要
本研究描述了一种新型的“SAVE”装置,通过有限元分析(finite element analysis, FEA)量化和评估上颌的变化,有效地延长了III类错颌的缺失上颌。材料和方法:使用Autodesk Fusion 360对获得专利的新型SAVE装置进行三维建模。现有的计算机断层扫描(CT)扫描显示III类错牙合的病人被用来产生一个有限元(FE)模型。节点总数为8,49,682,元素总数为5,30,716。器械的材料选择是医用级聚醚醚酮(PEEK)聚合物。加载模拟上颌拉伸(在指定材料属性后)。模拟各侧与咬合平面成30°角的3.5、5.5和9 N的加载力。颜色根据最大(红色)和最小(蓝色)变形区域变化。结果:拉伸力为3.5、5.5、9 N时的有限元分析结果显示上颌向前、向下均有变形。SAVE装置上的等效von Mises应力显示主框架的上表面和力模块连接的支柱下方区域的应力。相对于种植体,应力集中在种植体周围的后上方区域。结论:有限元分析力向量显示上颌向前和向下的变形,逆时针旋转,支持新型矫治器可以在较短的时间内实现有效的上颌牵引。本文引用方式:Shetty S, T NB, Amin V等。SAVE:一种新型上颌牵引装置的效果-有限元分析。中华儿科杂志(英文版);2009;17(12):1377-1382。
Efficacy of SAVE: A Novel Maxillary Protraction Device-A Finite Element Analysis.
Introduction: This study describes a novel device known as "SAVE" to effectively protract the deficient maxilla in class III malocclusion by quantifying and evaluating the changes in the maxilla through a finite element analysis (FEA).
Materials and methods: The patented novel SAVE device was three-dimensionally modeled using Autodesk Fusion 360. An existing computed tomography (CT) scan of a patient exhibiting class III malocclusion was used to generate a finite element (FE) model. The total number of nodes was 8,49,682 and 5,30,716 elements. The material of choice for the appliance was medical-grade polyetheretherketone (PEEK) polymer. The loading was performed to simulate maxillary protraction (after assigning material properties). The loading forces of 3.5, 5.5, and 9 N were simulated on each side with 30° angulations to the occlusal plane. The color changes in terms of areas of maximum (red) and minimum (blue) deformation.
Results: The FEA results with protraction forces of 3.5, 5.5, and 9 N showed deformation of the maxilla in the forward and downward directions. Equivalent von Mises stress on the SAVE appliance showed stress on the superior surface of the main frame and on the area below the struts where the force module was attached. In relation to the implant, the stress concentration was on the posterior and superior area around the implant.
Conclusion: The FEM analysis force vectors showed a forward and downward deformation of the maxilla with counterclockwise rotation, supporting the fact that the novel appliance could bring about effective maxillary protraction in a shorter duration.
